– Always wear a dust mark during work.

Instructions on operation:

Sawing method
** Danger
– Keep hands away from the cutting area and the blade. Keep your second hand on the 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 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 the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
– Hold the 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 could give the operator an electric shock.
– 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 off-centre, causing a loss of control.
– Never use damaged or incorrect blade washers or bolts. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.
Kickback causes and related warnings
– kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing anuncontrolled saw to lift up and out of the workpiece toward the operator;
– When the blade is pinched or jammed 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, center the saw blade in the kerf so that the saw teeth are not engaged in the material. If a saw blade binds, 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.
Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding, and kickback.
Blade depth and bevel adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding and kickback..
Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.
Lower guard function
Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of the cut. Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. The lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
– The lower guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”. Raise the lower guard by the retracting handle and as soon as the blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.
– Always observe that the lower guard is covering the blade before placing the saw down on the bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after the switch is released.
Riving knife function
– Use the appropriate saw blade for the riving knife. For the riving knife to function, the body of the blade must be thinner than the riving knife and the cutting width of the blade must be wider than the thickness of the riving knife.
– Adjust the riving knife as described in this instruction manual. Incorrect spacing, positioning, and alignment can make the riving knife ineffective in preventing kickback.
– Always use the riving knife except when plunge cutting. The riving knife must be replaced after plunge cutting. The riving knife causes interference during plunge cutting and can create kickback.
– For the riving knife to work, it must be engaged in the workpiece. The riving knife is ineffective in preventing kickback during shortcuts.
– Do not operate the saw if the riving knife is bent Even a light interference can slow the closing rate of a guard.
Instructions on service and maintenance:**
– Regularly cleaning the machine, especially the adjusting devices and guides, constitutes an important safety factor.
– Only original MAFELL spare parts and accessories may be used. Otherwise, the manufacturer will not accept any warranty claims and cannot be held liable.

Setting / Adjustment

4.1 Charging the rechargeable battery
Check whether the rated voltage of the rechargeable battery agrees with the information specified on the machine.
The rechargeable battery and charger are matched to each other. Only use the MAFELL – APS 18 chargers for recharging.
Before using a new machine, first of all charge the rechargeable battery.
A description of how to start up and charge the APS 18 can be found in the appended instructions “APS 18 rechargeable power station”. The rechargeable battery is equipped with a temperature monitoring system. This guarantees that the rechargeable battery is only charged in the temperature range between 0°C and 50°C. This achieves a long service life for the rechargeable battery.
A considerably shortened operating time per charging procedure indicates that the rechargeable battery is spent and needs to be replaced.
Danger
Explosion hazard
Protect the rechargeable battery from heat, fire, and moisture.
Do not place the rechargeable battery onto heating appliances and do not expose the rechargeable battery to strong solar radiation for a longer period of time. Temperatures above 50°C are detrimental to the rechargeable battery. Allow a heated rechargeable battery to cool down before charging it. The optimum storage temperature ranges between
10°C and 30°C.
Do not open the rechargeable battery and protect it from impacts. Keep the rechargeable battery in a dry and frost-proof place.
Danger

For cuts in laminate:
– Circular saw blade carbide Ø 120 x 1.8 x 20 mm (4 ¾ x 5/64 in. x 20 mm), 40 trapezoidal teeth
Order No. see special accessories.
4.6 Saw blade change

**** Danger
Unplug the rechargeable battery for all service work.

  1. Press the locking bolt 8 (Fig. 2).
  2. Using the Allen-key 3 (brackets Fig. 1), unfasten the flange screw 8 (Fig. 3) counterclockwise; remove the screw as well as the front clamping flange 7.
     Now you can remove the saw blade after opening the retractable saw guard 9.
     The clamping flanges must be free of adhering parts.
     Pay attention to the sense of rotation when inserting the saw blade.
     Afterward, mount the clamping flange, attach the flange screw and tighten it by clockwise turning.
     In doing so, keep the locking bolt depressed.

4.7 Riving knife/splitter
**** Danger

Unplug the rechargeable battery for all service work. The riving knife/splitter 6 (Fig. 3) prevents the saw blade from jamming during longitudinal cutting. The
correct distance to the saw blade is shown in (Fig. 8).

  • For adjustment, unfasten screw 4 (Fig. 3) with the Allen key supplied with the saw 3 (Fig. 1).
  •  Adjust the riving knife/splitter by shifting it in its longitudinal slit. Afterward, retighten the screw.

Operation

5.1 Initial operation
Personnel entrusted to work with the machine must be made aware of the operating instructions, calling particular attention to the chapter “Safety instructions”.
5.2 Switching on and off

  • Switching on: First press the switch-on lock 1 (Fig. 1) and then press the switch trigger 2.
  • Switching off: To switch off, release the switch trigger.

5.3 Cutting depth adjustment
The cutting depth is continuously variable between 0 and 40 mm (1 15/16 in.).
Proceed as follows:

  • Unfasten the clamping lever 5 (Fig. 1).
  • Set the cutting depth with the plunge lever 6 (Fig. 2).
  • The cutting depth can be read off the scale 2 (Fig. 5) on the cover. Zone 1 on the plunge lever with the red background serves as indicator for this purpose.
  • Retighten the clamping lever.

Always set the cutting depth approx. 2 to 5 mm (5/64 to 13/64 in.) larger than the material thickness to be cut.
5.4 Setting for bevel cuts
For bevel cuts, the saw unit can be set to any angle between 0° and 45°.

  • Unfasten the wing screws 5 (Fig. 3).
  • Adjust the angle according to the scale on the segment for tilting.
  • Afterward, tighten the wing screws 5.

5.5 Setting for miter cuts

  • Release the limit stop 21 (Fig. 7) and adjust the angle plate according to the scale on the guide rail.
  • Afterward, retighten the limit stop.
  • Place the machine with the two stop bolts at the bottom side of the guide rail against the workpiece to be processed and carry out the cut by pushing the machine forward.
  • After the cut, return the saw to its original position by reversing.

5.6 Plunge cuts

Danger
Risk of backlash during the plunge cuts! Prior to plunging, place the machine with the rear edge of its base plate against a limit stop fastened on the workpiece. Keep a firm hold on the machine handle during plunging and push the saw lightly forward!

  • Unfasten the clamping lever 5 (Fig. 1) on the switched-off machine.
  • Reset the plunge lever 6 (Fig. 2).
  • Open the retractable saw guard with lever 2 (Fig. 3) so that the machine can be placed onto the workpiece to be machined. The saw blade is now running freely above the material and can be aligned for tracing.
  • Switch on the machine only now.
  • Push the plunge lever 6 (Fig. 2) vertically downwards so that the saw blade plunges vertically into the workpiece. While doing so, the plunge depth can be read off the scale 2 (Fig. 5). The riving knife/splitter swings up and away when the blade enters the workpiece. As soon as the slit behind the saw blade is cleared during the forward motion of the machine, the riving knife reverts to its normal position.

5.7 Sawing with FLEXI rail
Danger
The support rail is pre-tensioned and may snap open in an uncontrolled manner – the risk of injury. It should therefore be securely held with both hands during opening and closing.
Initial operation
Trim the splinter guard 4 (Fig. 4) before initial operation:

  • Place the FLEXI rail on a flat support.
  • Set the cutting depth to approx. 3 mm ( 1/8 in. ) and the angle scale to 0°.
  • Turn on the machine and push it evenly in the direction of the cut. The resulting cut edge on the splinter guard serves as a tracing edge for straight cuts and bevel cuts.
  • Place the FLEXI rail onto the workpiece. Knock against the workpiece and align it on the tracing. So as to fix the FLEXI rail, tighten the two clamping claws 1 (Fig. 6) with the screw clamps.

Operating method

  • Set the cutting depth and cutting angle on the machine.
  • Place the machine on the start of the FLEXI rail such that the guide elements 1 (Figure. 4) of the rail engage in the base plate groove.
  • Turn on the machine and push it evenly in the direction of the cut.

Do not clean the FLEXI rail with solvents. The non-skid coating may get damaged.

5.8 Sawing shadow gaps
The minimum shadow gap width is:

– if used without parallel stop 13 mm (33/64 in.)
– if used with parallel stop 14 mm (35/64 in.) (at cutting depth of 0 – 32 mm / 0 – 1 ¼ in.)
– if used with parallel stop 18 mm (45/64 in.) (at cutting depth of 32 – 42 mm / 1 ¼ – 1 21/32 in.)

  • Set the required cutting depth.
  • Retract the retractable saw guard with lever 2 (Fig. 3) and set the machine onto the first fitted workpiece.
  • Switch on the machine and push the machine evenly in the cutting direction, in addition using the extraction device.

5.9 Sawing with parallel stop

The parallel stop 4 (Fig. 1) serves to cut parallel to an already existing edge. The limit stop can be attached to the left or right of the machine. The cutting range on the right-hand side amounts to approx. 65 mm (2 9/16 in.) and on the left-hand side to approx. 250 mm (9 27/32 in.).
You can adjust the cutting width after unfastening the wing screws 9 (Fig. 2) by moving the limit stop accordingly and afterward refastening the wing screws.
In addition, by simply turning it over (the guide surface for the workpiece edge is pointing upwards), the parallel stop can be used as double support to improve machine guidance. Now the machine can be guided along with a lath that is fastened on the workpiece.
5.10 Sawing according to tracings with guide rail
When sawing according to tracing, the right edge of the guide rail serves as a tracing indicator. This also applies to bevel cuts. Please take note of Section 5.4.

  • For sawing, place the guide rail onto the workpiece.
  • Switch on the machine (see Chapter 5.2) and slide the machine evenly in the cutting direction.
  • When the cut is completed, switch off the saw by releasing the switch trigger 2 (Fig. 1)
  • While it is resting on the workpiece, pull the machine back into the home position and in this position remove it from the workpiece. Proceeding in this manner ensures that the retractable saw guard is completely closed.

5.11 Sawing according to tracings without guide rail
Danger
When sawing without a guide rail it is imperative to install the enclosed parallel stop. It serves as double support to improve machine guidance and is for your safety.
Set the machine’s cutting depth to at least 30 mm (1 3/16 in.). Afterward, you can remove the machine from the guide rail to the rear by actuating the lockinglever 20 (Fig. 7).
The base plate is equipped with a tracing edge 10(Fig. 3) both for straight cuts and for bevel cuts. This tracing edge corresponds to the saw blade’s inside.
For bevel cuts, the tracing can be viewed through the opening on the left-hand side of the upper saw guard.

  • Hold the machine by its handles and place the front part of its base plate onto the workpiece.
  •  Switch on the machine and evenly advance the machine in the cutting direction.
  • When the cut is completed, switch off the saw by releasing the switch trigger 2 (Fig. 1).
