Description – purpose of use

Cordless mitre and chop saw with laser Extol® Industrial, that is part of the SHARE 20 V cordless power tool product range, is intended for performing precision cross and longitudinal cuts on wood used for construction purposes, for wood fiber, chipboard as well as thin plastics, aluminum profiles and thin non-steel materials with the use of circular saw blades intended for such purposes. The circular saw blade, which is a part of the saw is intended only for cutting wood.

Other materials such as, for example, steel, concrete, mineral materials must not be cut with these saws.

• The advantage of a miter and chop saw is the accuracy of the performed cut at an angle, which cannot be achieved using hand-held jigsaw or circular saws, where inaccurate cutting angles do not enable the cut materials to align as accurately as necessary.
• Option to set the mitre cutting angle (cut in the horizontal plane) in the range -45°/90°/+45° (left/right) and a chopping cutting angle (vertical angle) of 90-45° (left).
• Laser beam makes accurate alignment of the cut easier.
• Motor without carbon brushes provides more power output with lower power consumption for longer battery life and a longer lifespan.
• The saw has a removable dust collection bag.

The motor and the battery have electronic protection against overloading, which disconnects the power supply when an excessive load is detected.

The battery is equipped with electronic protection against full discharge, which damages it and which shuts off el. power supply when the battery’s terminal voltage falls below a certain threshold.

To put the dust bag on to the sawdust exhaust, it is necessary to enlarge the diameter of the bag clamp by moving the wire loops towards each other (fig. 3A), then slide it on to the sawdust exhaust and then release the wire loops (fig. 3B).

UNLOCKING ARM TRAVEL (FIG. 4)
To unlock arm travel, loosen the travel locking bolt (fig. 4).

ADJUSTING THE MITRE (HORIZONTAL) CUTTING ANGLE (FIG. 5)

To adjust the mitre cutting angle, release the rotating table from the locked position by turning the handle (fig. 1, position 24), then lift the lever (fig. 1, position 23) and turn the table to the required angle value on the scale, where the currently set value is determined by the position of the indicator on the scale (fig. 5). Secure the rotating table in the set position by turning the rotating handle (fig. 1, position 24). Prior to putting the saw into operation, always properly check that the table is securely locked at the set mitre cutting angle with the rotating handle.

ADJUSTING THE CHOP (VERTICAL) CUTTING ANGLE (FIG. 6)

In the event that it is necessary to adjust the chop cutting angle, release bolt (fig. 1, position 6) and tilt the arm to the side in the range 90°to 45°, whilst the currently set angle of the arm is given by the position of the indicator on the angle scale. Then firmly secure the saw arm at the set angle by tightening the bolt (Fig. 1, position 6).

INSTALLING THE WORKPIECE CLAMPING CLAMPS WITH SIDE SUPPORTS (FIG. 7)

• When working with the saw, always secure the workpiece in place against free movement using the clamping clamp. Secure the pin on which the clamping clamp is inserted in the base of the saw by tightening the bolt.
• Into the respective holes on both sides of the base, as shown in fig. 7, insert the bars of the side support (fig. 1, position 3) and in the base of the saw, secure both supports using the bolt.

WARNING
For safe work with the saw, it is necessary that the saw is used only with the complete accessories, i.e. with the side supports and the workpiece clamping clamp. The saw is shown completely assembled in fig. 7.

POSITIONING AND CLAMPING THE WORKPIECE (FIG. 8)

Place the workpiece against the partition (fig. 1, position 25) along the full length of the partition to safely secure the workpiece during the cutting process and secure it in place by screwing in the clamping clamp. Prior to putting the saw into operation, secure all the fastening elements of the clamping clamp against coming loose

ADJUSTING THE CUTTING DEPTH (FOR MAKING GROOVES)
The cutting depth can, if necessary, be set or adjusted using bolt (fig. 1, position 15), which sits on the limit stop (depth limit stop) (fig. 1, position 14) during the cutting process.

TURNING THE LASER EMITTER ON/OFF
Turn on the laser emitter by setting button (fig. 1, position 10) to the „I“ position. To turn it off, set it to the „0“ position.

CHECKING THE CORRECT FUNCTION OF THE SAW BLADE GUARD
If the saw arm is in the top position, the saw blade guard covers the circular saw blade. When tilting down the arm towards the saw table, the circular saw blade is automatically uncovered depending on how far the arm is tilted down. If the circular saw blade guard is not functioning correctly, do not use the saw and arrange for its repair at an authorised service centre for the Extol® brand.

Using the saw

INSERTING THE BATTERY
Insert a charged battery into the respective location on the saw (fig. 1, position 8) so that the battery is secured in place, which is confirmed by an audible click.

WARNING
Only use the power tool when the work surface, the groove in the saw table and the workpiece are free of unwanted items and debris (splinters, nails, soil, mortar, etc.). Small pieces of wood or other items, which come into contact with the rotating circular saw blade may be ejected and thereby cause injury to the user

TURNING THE SAW ON/OFF (FIG. 9).

WARNINGS

• Prior to putting the saw into operation, check that the workpiece is placed against the support partition along the entire length of the partition and that it is properly secured in this position with the clamping clamp. Do not cut material that is not properly flush with the saw table and that is not flush with the partition, e.g. branches, crooked, non-straight workpieces, etc. This could easily result in their ejection or jamming of the circular saw blade, etc. and may result in injury to the user.
• Check that the circular saw blade is properly secured in place and check that it has no cracks, that it is not bent, unbalanced, and that no tungsten carbide (TC) tips are missing. Do not use the saw with a damaged circular saw blade and arrange a replacement circular saw blade that is in perfect condition, which meets norm EN 847-1 and that corresponds to the technical specifications provided in chapter II – part number of the new circular saw blade for cutting wood Extol® Industrial 8791826A.

This is a special circular saw blade that is thin and light, and specially manufactured for cordless saws.

A thicker, heavier circular saw blade with other parameters could result in damage to the saw.
A damaged circular saw blade must not be repaired.

Use circular saw blades that have the same or higher speed specified on them than the speed specified on the rating label of the saw.

ATTENTION

• For cutting metals and/or plastics, use only special circular saw blades intended for such purposes. The circular saw blade supplied with the saw is intended exclusively for cutting wood and wooden materials and must not be used for cutting other materials.
• The saw is intended only for dry cutting without the use of water or liquid oil as coolant.

WARNINGS

Dust is generated during the cutting process, the inhalation of which is damaging to health, especially dust from chemically treated materials, therefore, always us the dust collection bag when working with the saw, and also use suitable protection of the respiratory tract with a filtration class of at least FFP2, and better yet FFP3 or a breathing mask (with a sufficiently level of protection of the respiratory tract and seek advice at a personal protective equipment store with respect to the workpiece material being cut. Ensure quality ventilation of the area during work. Dust from certain types of wood, e.g. oak and beech is considered carcinogenic.

Furthermore, use certified ear and eye protection, suitable work gloves and work clothing with a sufficient level of protection. Consult the sufficient level of protection and the suitability of the protective equipment at a personal protective equipment store.

PROCEDURE

1. Grasp the handle with your hand (fig. 1, position 12).
2. To start the saw, push down the trigger lock release button (fig. 1, position 13) and then press the trigger (fig. 1, position 11).
3. Guide the arm of the saw towards the workpiece running at full speed, whilst starting the cut from the side of the workpiece that is not leaning against the support partition and perform the cut along the cut line marked by the laser or a pencil, applying appropriate guiding force in the direction towards the support partition – do not exert excessive force on the circular cutting blade! To move the arm in the horizontal direction, the travel of the arm must be released (unlocked).
4. After performing the cut, do not release the arm of the saw from the lowest position, but rather, whilst applying counter pressure with your hand, allow it to rise to the top position, and the saw blade guard will cover the circular saw blade. Releasing the saw arm from the lowest position would result in the arm being thrust up to the top position, which could damage the saw.

ATTENTION
Overheating of the circular saw blade teeth manifests itself by the colour of the teeth changing, or by the melting of plastics (if plastics are being cut), which may be caused by excessive pressure being applied on to the circular saw blade while cutting, clamping of the circular saw blade in the workpiece or by the use of an inappropriate circular saw blade for cutting the given material. Please inform yourself about the suitability of use of the given circular saw blade for the given material from the manufacturer or supplier of the circular saw blade.

WARNING
Do not put your hands in the cutting area. Keep your hands at a safe distance from the cutting location.

WARNING
Prior to readjusting the power tool, always, for safety reasons, release the trigger of the saw and wait until the circular saw blade comes to a complete stop.

ATTENTION
In the event that there is an evident, unusual noise, vibrations or operation during the operation of the saw, immediately turn it off, disconnect it from the el. power supply and identify and rectify the cause of this unusual operation. If the unusual operation is caused by a fault inside the power tool, have it repaired at an authorised service centre for the Extol® brand through the vendor or directly at an authorised service centre (service locations are listed at the website address at the start of this manual).

INFORMATION ABOUT THE BATTERY/RUNNING TIME

The battery is equipped with electronic protection against full discharge, which damages it, and thereby extends its lifespan. This protection manifests its self by the power tool coming to a sudden stop even when the power switch is in the „On“ position. After setting the power switch to the „Off“ position and then turning it on again, after a certain time the power tool will start up again, however, it will again stop suddenly. This is not a fault of the power tool or battery, but rather serves as protection. When longer operation is required, purchase a battery with a greater capacity.

The motor and the battery have electronic protection against overloading, which disconnects the power supply when excessive load is detected, which manifests itself by the power tool coming to a stop. This is not a fault of the power tool or battery, but rather serves as protection

TURNING OFF THE SAW
To stop the saw, release the trigger.

Folding the saw to the transport position and carrying the saw

1.  Set the mitre and chop angle to 90°/90° and in the given setting, secure it in place by tightening the locking elements.
2. Tilt the arm down so that it is possible to insert the pin (fig. 1, position 19) underneath the stopper. For this purpose, it may be necessary to screw out the cutting depth adjustment bolt (fig. 1, position 15), otherwise it will not be possible to sufficiently tilt down the arm to enable the pin to be inserted underneath the stopper.
3. Carry the saw in the folded down state as described in the steps in point 1-2, whilst holding the grip part as shown in fig.10.

Safety instructions for mitre saws

SAFETY INSTRUCTIONS FOR MITRE SAWS

• a) Mitre saws are intended for cutting wood or materials similar to wood; they must not be used with abrasive cutting discs, which are intended for cutting steel materials such as profiles, rods, nails, etc. Dust generated during grinding causes the moving parts, for example the bottom guard to become blocked. Sparks that are generated during abrasive cutting will burn the bottom guard, burr guard and other plastic parts.
• b) Whenever possible, it is necessary to fasten the workpiece using a clamp. If the user rests the workpiece against their hand, it is necessary to always hold the hand at least 100 mm from both sides of the circular saw blade. This saw must not be used for cutting workpieces that are too small to be safely clamped or held in the hand. In the event that the hand of the user is too close to the circular saw blade, then this presents an increased risk of injury caused by coming into contact with the circular saw blade.
• c) The workpiece must be immobile and must be fastened or held against the guide rule and the table. Under no condition may the workpiece be slid towards the circular saw blade or cut „hand held“. Unclamped or moving workpieces could fly out at high speed and cause injury.
• d. The user must never intersect the imaginary cutting axis with their hands, i.e. neither in front of or behind the circular saw blade. Holding the workpiece „cross-handed“, i.e. holding the workpiece on the right of the circular saw blade with the left hand or vice versa is very dangerous.
• e) It is forbidden to touch the guide rule with either hand closer than 100 mm from both sides of the circular saw blade, whether that be to remove an off-cut or for any other reason while the circular saw blade is rotating. The fact that the rotating circular saw blade located close to the hand of the user may not necessarily be apparent, and the user may thus suffer serious injuries.
• f) It is necessary to inspect the workpiece before cutting. If the workpiece is bent or twisted then it must be secured with the clamp in such a way that neither of its sides that is bent out is pointing towards the guide rule. It is always necessary to ensure that there is no gap between the workpiece, guide rule and the table. Bent or twisted workpieces may twist or slide and may cause the rotating circular saw blade to jam during the cutting process. There should be no nails or any other foreign objects inside the workpiece.
• g) The saw unit must not be used until all tools, off- -cuts, etc., except for the workpiece, are cleaned off the table. Small debris or fallen off wood pieces or other object that come into contact with the rotating circular saw blade may be deflected at high speed.
• h) Only a single workpiece my be cut at any one time. It is not possible to clamp multiple workpieces placed on top of each other and they may become stuck on the circular saw blade or lift up during the cutting process.
• i) Prior to use, it must be ensured that the mitre saw is mounted or located on a level, rigid, work surface. A level and rigid work surface will reduce the risk that the mitre saw could become unstable.
• j) Work needs to be properly planned. Every time that the mitre or chop angle is adjusted, it is necessary to check that the adjustable guide bar is correctly set and that it supports the workpiece and does not collide with the circular saw blade or the system of protective guards. With the power tool turned off and without the workpiece on the table, it is necessary to pull the circular saw blade through the entire simulated cut to enable the user to ensure that no collision can occur and that there is no risk of cutting into the guide bar.
• k) It is necessary to provide sufficient support, for example by extending the table, wood cutting trestle, etc., when cutting workpieces that are wider or longer than the work plate of the table. Workpieces that are longer or wider than the table of the mitre saw may tilt over when not safely supported. In the event that the off-cut or workpiece tilts over, it may lift up the bottom guard or may be deflected by the rotating circular saw blade.
• l) Another person may not serve as a substitute for an extension of the table or as a supplementary support. An unstable support of the workpiece may cause the circular saw blade to jam or for the workpiece to be lifted during the cutting process, whilst it may pull the user or the auxiliary equipment towards the rotating saw blade.
• m) An off-cut must not jam or in any way push on the rotating saw blade. If the off-cut limits, i.e. when the workpiece length limit stop is used, then the off-cut could wedge into the circular saw blade, which could eject it violently.
• n) It is always necessary to use the clamp or a jig designed for the proper clamping of round materials, e.g. rods or pipes. Rods/poles have a tendency to turn when being cut, which causes the circular saw blade to „bite-in“ and to pull the workpiece together with the hand of the user towards the circular saw blade.
• o) Prior to coming into contact with the workpiece, the circular saw blade is allowed to reach full speed. This reduces the risk of the workpiece being deflected.
• p) If the workpiece or the circular saw blade jams, then it is necessary to turn off the mitre saw. It is necessary to wait until all the moving parts come to a stop and to disconnect the power plug from the power source or to remove the battery pack. Then it is possible to work on releasing the jammed material. Continuing to cut with a jammed workpiece could result in loss of control or damage to the mitre saw.
• q) When the cut is complete and before removing the off-cut, it is necessary to release the trigger, to hold the saw head down and to wait from the circular saw blade to come to a stop. It is dangerous for the user to come near to the head with a rotating circular saw blade.

The process of braking the saw may cause the head of  the saw to be suddenly pulled downwards.

The power tool, as well as the laser, creates an electromagnetic field during operation, which may negatively affect the operation of active or passive medical implants (pacemakers) and threaten the life of the user. Prior to using this power tool, ask a doctor or the manufacturer of the implant, whether you may work with this power tool.

SAFETY INSTRUCTIONS FOR THE LASER

****
LASER 2

• Prevent the laser beam from coming into contact with eyes. Do not look into the laser beam. Do not point the laser beam into eyes. In the event that eyes are impacted, immediately move your head away as a protective measure. Do not view the beam with optical devices.
• Prevent the laser beam from coming into contact with shiny surfaces. Shiny surfaces may deflect the beam towards the user and may cause impact with the eyes.
• Do not substitute the installed laser with a different type. Have repairs or replacement performed at an authorized service center for the Extol® brand.

Safety instructions for circular saw blades

The circular saw blade was manufactured in accordance with the requirements of norm for saw blades EN 847-1. Prior to starting work, it is necessary to carefully read this user‘s manual and to subsequently follow the provided instructions.

SAFETY INSTRUCTIONS FOR CIRCULAR SAW BLADES

Prior to mounting a circular saw blade on to the power tool, read the power tool‘s user‘s manual and when working with the power tool, adhere to the safety instruction provided in the power tool‘s user‘s manual. Prior to mounting a circular saw blade on to the power tool, first ensure that the circular saw blade will be rotating in the correct direction – the rotation direction of the power tool‘s spindle and the rotation direction of the circular saw blade are indicated by arrows on the power tool and the circular saw blade. In the event of counter-rotation directions, the circular saw blade must not be used with the given power tool. Prior to working on a given material, first remove all foreign objects, e.g. nails, wire, etc.

Only use a circular saw blade that is sharp, clean and in flawless condition. Prior to putting the saw into operation, always first check that the circular saw blade is undamaged – check for cracks, any missing TC tips, deformati on, correct rotational balance, etc. It is not permitted to repair damaged circular saw blades.

The circular saw blade may only be used by trained persons that have sufficient experience and skill in using tools
and handling them. The maximum rotation frequency indicated on the power tool must not be exceeded. If a rotation speed range is specified then it must be adhered to. Circular saw blades with a cracked body, must be discarded (repair is not permitted). Integral tools with visible cracks must not be used. Tools and tool elements must be clamped in such a manner that they must not come loose during work. On tools with a power connection, a cr and ca adjusting gauge must be used to ensure the radial and lateral blade overlaps. Tools must be mounted very carefully to ensure that the tool is clamped by its hub, i.e. clamping surface, and that the cutting edges are not touching each other or the clamping elements.

The fastening bolt and nut must only be tightened with respective tools, etc. and to the tightening torque specified by the manufacturer. Extending the length of arms of the tightening wrenches or using hammer impacts is not permitted. The clamping surface must be clean and free of any substances such as Vaseline, oil or water. Clamping bolts must be tightened according to the manufacturer‘s instructions. Only pressed or glued on solid rings may be used for setting the size of the saw blade hole to the diameter of the shaft. Using loose rings is not permitted.

Do not apply excessive pressure on to the circular saw blade when using it as this will overload the power tool or potentially overheat the tips of the circular saw blade and lead to poor quality results.

Resins and other stuck on materials may only be removed from the circular saw blade using solvents that do affect the mechanical properties of the circular saw blade. To clean the circular saw blade, use a brush with synthetic fibres. In the event that the circular saw blade is damaged, e.g. rotational imbalance as a result of being dropped, then for safety reasons, the circular saw blade must not be used. It is not permitted to repair a circular saw blade. In the event that it is necessary to sharpen the circular saw blade, have the circular saw blade sharpened by a professionally competent person with knowledge about construction requirements and awareness of the level of safety that should be achieved. When sharpening the circular saw blade, its rotational balance must remain unchanged. When sharpening a circular saw blade, it is necessary to ensure that the hub and the connection between the hub and blade is not weakened. The construction design of permanently connected tools must not be changed. Tolerances that ensure correct clamping must be maintained.

When handling the circular saw blade, use suitable protective gloves as protection against injury since the circular saw blade is sharp and may heat up to a high temperature during use.

Protect the circular saw blade against impacts and falls. Prior to transporting a circular saw blade that is not installed in the saw, insert it into a protective cover to protect it against damage.

Prior to putting the power tool into operation, with the battery removed (power supply to the saw is disconnected), first check that the circular saw blade is securely clamped on to the spindle of the power tool and that no part of the circular saw blade is touching the saw blade guard of the power tool.

When working with the circular saw blade, use certified eye, ear, hearing and breathing protection and gloves with a sufficient level of protection.

Maintenance and Repair

WARNING

• Prior to performing maintenance on the saw, remove the battery to eliminate the risk of accidental start up.
• Keep the power tool and motor vents clean. Regularly check that the motor vents are clean. Clogged vents prevent air circulation, which may cause overheating and damage to the motor.
• Dust can be cleaned away from the saw using pressurised air from an air gun, however, prevent pressurised air from coming into contact with the motor vents to prevent dust from entering the motor, or vacuum it out using a suitable industrial vacuum cleaner. Regularly remove short off-cuts and dust from the cutting groove (insert) in the table, e.g. by vacuuming with an industrial vacuum cleaner. Ensure that debris (off-cuts, splinters and dust) do not prevent the movement and function of the protective guards and adjustable elements. Before and after using the saw, it is necessary to check for the flawless functionality of all the protective and moving elements of the saw. Otherwise, do not use the saw and arrange a remedy.
• It be cleaned using a damp cloth, however, prevent the ingression of water into the power tool. Do not use aggressive cleaning products and solvents, this would result in damage to the plastic casing of the power tool.

INSTALLATION/REPLACEMENT OF THE CIRCULAR SAW BLADE

For cutting wood, install the circular saw blade Extol® Industrial 8791826A, which is a thin and light blade that is specially made for cordless saws. Using a thicker, heavier circular saw blade could damage the saw. Only circular saw blades which are marked with the same or higher rotation speeds than the rotation speed marked on the rating label of the saw and in the user‘s manual may be used. Only use the circular saw blades intended for the given type of material.

Circular saw blades with different parameters or those intended for different materials, may cause injury or damage the saw.

• Do not use blunt, damaged or warped circular saw blades. Circular saw blades with blunt or inappropriately
  arranged teeth cause increased friction, clamping of the circular saw blade and kickback. Blunt circular saw blades may only be sharpened by a specialist on sharpening equipment. The welding of cracks and repair of other defects on the circular saw blade is not permitted. In the event of damage to the circular saw blade, it is necessary to replace it with a new one.

• For cutting wood and similar materials, use only circular saw blades that meet the requirements of norm EN 847-1.

• When replacing the circular saw blade, use protective work gloves as protection against the sharp saw teeth. After using the saw, before replacing the circular saw blade, wait until it cools down.

• The circular saw blade supplied with the saw is intended only for cutting wood. For cutting soft non-steel metals and plastics, it is necessary to use a circular saw blade intended for this purpose.

PROCEDURE FOR REPLACING/INSTALLING CIRCULAR SAW BLADES (FIG. 11 – FIG. 15):

1. Secure the travel of the arm by tightening the locking bolt (fig. 1, position 18).
2. Tilt open the circular saw blade guard.
3. Press the spindle lock button (fig. 1, position 20) and turn the circular saw blade by hand to block the rotation of the spindle.
4. With the saw blade guard tilted out, screw out the cover of the saw blade clamping bolt and screw out the bolt and remove the clamping washer and remove the circular saw blade from the spindle (fig. 11 – fig. 15).
5. Put a new circular saw blade on to the spindle in such an orientation that the rotation direction arrow marked on the circular saw blade points in the same direction as the arrow marked on the saw blade guard.
6. To fasten the circular saw blade in place, proceed in the reverse order to disconnecting it.
7. With the rotation of the spindle locked, use your hand to check that the circular saw blade is firmly clamped on the spindle and is not slipping (rotating).
8. Finally check that the saw blade guard automatically covers the circular saw blade, that the arm is in the top position and that the circular saw blade is uncovered when the arm is tilted down.
