Special Safety Instructions

For your own protection and for the protection of your power tool pay atten- tion to all parts of the text that are marked with this symbol!

Sawing procedure

• DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
• Do not reach underneath the workpiece. The safety guard cannot protect you from the blade below the workpiece.
• Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
• Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable platform. It is important to support the work properly to minimise body exposure, blade binding, or loss of control.
• Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and shock the operator.
• When ripping always use a rip fence or straight-edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
• Always use blades with the correct size and shape (diamond versus round) of arbour holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
• Never use damaged or incorrect saw blade plain washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.

Kickback – causes and corresponding safety instructions

• kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the work-piece toward the operator;
• when the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
• if the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

• Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backward, but kickback forces can be controlled by the operator if proper precautions are taken.
• When the blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw teeth are not engaged into the material. If the saw blade is binding, it may walk up or kick-back from the workpiece as the saw is restarted.
• Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
• Do not use dull or damaged blades. Unsharp-ened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kick-back.
• Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.
• Use extra caution when making a “plunge cut” into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

Function of the lower protective cover

• Do not operate the saw if lower safety guard does not move freely and close instantly. Never clamp or tie the bottom safety guard in an open position. If the saw is accidentally dropped, lower safety guard may be bent. Raise the lower guard with the retracting handle (25)and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.
• Check the operation of the lower safety guard spring. If the safety guard and the spring are not operating properly, they must be serviced before use. Lower safety guards may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
• Open the lower safety guard by hand only when making special cuts, such as plunge cuts and angle cuts. Raise lower guard by retracting the handle (25) and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower safety guard must be released.
• Always observe that the lower safety guard is covering the blade before placing saw down on the bench or floor. An unprotected, coasting blade will cause the saw to walk backward, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

Do not use grinding wheels.
Keep hands away from the rotating tool! Remove chips and similar material only with the machine at a standstill.
Wear ear protectors.
Wear protective goggles.

• Press the spindle locking button only when the motor is at a standstill.
• Do not reduce the speed of the saw blade by pressing on the sides.
• The movable safety guard must not be clamped in the pulled-back position for sawing.
• The movable safety guard must move freely, auto-matically, easily, and exactly back into its end posi-tion.
• When sawing materials that generate large quantities of dust, the machine must be cleaned regularly. Make sure that the safety appliances, e.g. the movable safety guard, are in perfect working order.
• Materials that generate dusts or vapors that may be harmful to health (e.g. asbestos) must not be processed.
• Check the workpiece for foreign bodies. When working, always make sure that no nails or other similar materials are being sawed into.
• If the saw blade blocks, turn the motor off immediately.
• Do not try to saw extremely small workpieces.
• During machining, the workpiece must be firmly supported and secured against movement.
• Dust from materials such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders.
• Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists.
  • Where the use of a dust extraction device is possible it shall be used.
  • To achieve a high level of dust collection, use a suitable Metabo vacuum cleaner together with this tool.
  • The workplace must be well ventilated.
  • The use of a dust mask of filter class P2 is recommended.
• Follow national requirements for the materials you want to work with.
• Clean gummy or glue-contaminated saw blades. Contaminated saw blades cause increased friction, jamming of the saw blade and increase the risk of back-kicks.
• Avoid overheating of the saw tooth tips. Avoid melting of the material when sawing plastic. Use a saw blade that is suitable for the material being sawn.
• Protect battery packs from water and moisture!
• Do not use faulty or deformed battery packs!
• Do not expose battery packs to naked flame!
• Do not open battery packs!
• Do not touch or short-circuit battery packs!
• Remove the battery pack from the machine when not in use.
• Remove the battery pack from the machine before any adjustment or maintenance is carried out.
• Before fitting the battery pack, make sure that the machine is switched off.
• Slightly acidic, flammable fluid may leak from defective Li-ion battery packs!
• If battery fluid leaks out and comes into contact with your skin, rinse immediately with plenty of water. If battery fluid leaks out and comes into contact with your eyes, wash them with clean water and seek medical treatment immediately.
• LED working light (8): Do not observe the LED radiation directly with optical instruments

Initial Operation, Setting

IRemove the battery pack from the machine before any adjustment or maintenance is carried out. Before fitting the battery pack, make sure that the machine is switched off.

Battery pack

Charge the battery pack before use (12).
If performance diminishes, recharge the battery pack.

“Li-Power” li-ion battery packs have a capacity and signal indicator: (26)

• Press the (27) button, the LEDs indicate the charge level.
• If one LED is flashing, the battery pack is almost flat and must be recharged.

Removal:
Press the battery pack release (13) button and pull the battery pack (12) upwards.

Inserting:
Slide in the battery pack (12) until it engages.

Setting depth of cut

Loosen the locking screw (19). Read the depth of cut that has been set from the scale (18). Tighten the locking screw again.
It is advisable to set the depth of cut in such a way that no more than half of each tooth on the saw blade juts out under the workpiece. See illustration on page 3.

Slanting saw blade for diagonal cuts
Loosen the locking screw (2). Tilt the motor part against the guide plate (7). Read the angle which has been set from the scale (1). Tighten the locking screw again.

Correcting the saw blade angle
If, at 0°, the saw blade is not at right angles to the guide plate: release lock nut (17) and correct saw blade angle with adjusting screw (16). Then retighten the lock nut.

Extraction connection piece / dust  ejection

• Sawdust extraction:
  connect a suitable dust extraction unit with suction hose to the connection piece to extract the sawdust. (6)

• Sawdust ejection:
  Turn the nozzle (6) to the desired position (away from body if possible).

Use

Automatic protection mode If the machine switches off automatically, the machine electronics have activated automatic protection mode. A warning signal sounds (continuous beeping). The beeping stops after a maximum of 30 seconds or when the trigger is released (5).

Causes and remedies

1. Battery pack almost flat (the electronics prevent the battery pack from discharging totally and avoid irreparable damage).
   If one LED is flashing (26), the battery pack is almost flat. If necessary, press the (27) button and check the LEDs (26) to see the charge level. If the battery pack is almost flat, it must be recharged.

2. Long continuous overloading of the machine will activate the temperature cut-out. Leave the machine or battery pack to cool.
   Note : If the battery pack feels very warm, the pack will cool more quickly in your “AIR COOLED” charger.
   Note : The machine will cool more quickly if you operate it at idling speed.

3. If the current is too high (for example, if the machine seizes continuously for long periods), the machine switches off.
   Switch off the machine at the trigger (5). Then continue working as normal (in this case, read in particular the safety instructions in Chapter

4. Kickback… in addition to all other safety instructions). Try to prevent the machine from seizing.

Switching on and off
Switching on: Press locking button (4) and hold in; then actuate the trigger (5).
Switching off: Release the trigger (5).

Working instructions

• Do not switch the machine on or off while the saw blade is touching the workpiece.

  • Let the saw blade reach its full speed before making a cut.
  • When the hand-held circular saw is added, the movable guard is swung backwards by the workpiece.
  • When sawing, never remove the machine from the material with the saw blade turning.
  • Allow the saw blade to come to a standstill.
  • If the saw blade blocks, turn the machine off immediately.

• Sawing along a straight line: the cutting indicator is used here (10). The left notch (marked 0°) indicates the direction of the cut if the saw blade is held vertically. The right notch (marked 45°) indicates the direction of the cut if the saw blade is held at 45°. Sawing along a rail secured on the workpiece: In order to achieve an exact cutting edge, you can attach a rail to the workpiece and then guide the hand-held circular saw by means of the guide plate along this rail.

• Sawing with parallel stop :
  For cuts parallel to a straight edge. The parallel guide (9) can be inserted from either side into the support provided for it. Read the cut width from the right or left of the cutting display (10). Tighten the locking screw (11). It is best to calculate the exact cut width by making a test cut.

• Sawing with guide rail 6.31213:
  For straight, tear-free cut edges, precise to the millimetre.
  The anti-slip coating keeps the surface safe and protects the workpiece against scratches. For  guide rail 6.31213, see chapter on Accessories.

• Battery pack heat generation:
  Under extremely hard application conditions (e.g. sawing thick wooden planks), the heavy load can cause the battery pack to heat (> 60 °C). To conserve the battery pack, allow it to

LED lights

Vibration total value (vector sum of three directions) determined in accordance with EN 60745:

• ah, D = Vibration emission value (Sawing chipboard)
• Kh,D = Uncertainty (vibration)

The vibration emission level given in this information sheet has been measured in accordance with a standardized test given in EN 60745 and may be used to compare one tool with another. It is also suitable for a provisional estimate of the vibratory load.
The specified vibration level applies to the main applications of the power tool. However, if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This can considerably increase the vibratory load over the entire working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintaining the tool and the accessories, keeping the hands warm, organization of work patterns.

Typical A-effective perceived sound levels:

• LpA = Sound pressure level
• LWA = Acoustic power level
• KpA, KWA= Uncertainty (noise level) During operation the noise level can exceed 80 dB(A).
