Switching On and Off (Fig. A)
For safety reasons the trigger switch
1
of your tool is equipped
with a lock‑off button
2
.
Press the lock‑off button to unlock thetool.
To run the tool, press the trigger switch
1
. As soon as the
trigger switch is released, the lock‑off switch is automatically
activated to prevent unintended starting of themachine.
NOTICE: Do not switch the tool ON or OFF when the saw
blade touches the workpiece or othermaterials.
LED Worklight (Fig. A)
The LED worklight
10
is activated when the trigger switch is
depressed. When the trigger is released, the worklight will stay
illuminated for up to 20seconds.
NOTE: The worklight is for lighting the immediate work surface
and is not intended to be used as aflashlight.
Proper Hand Position (Fig. V)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position asshown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
suddenreaction.
Proper hand position requires one hand on the main handle

OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.
Prior to Operation
• Make sure the guards have been mounted correctly. The
saw blade guard must be in closedposition.
• Make sure the saw blade rotates in the direction of the
arrow on theblade.
• Do not use excessively worn sawblades.
Kerf Indicator (Fig. S–U)
The front of the saw shoe has a kerf indicator
41
for vertical
and bevel cutting. This indicator enables you to guide the saw
along cutting lines penciled on the material being cut. The kerf
indicator lines up with the left (outer) side of the saw blade,
which makes the slot or “kerf” cut by the moving blade fall to
the right of the indicator. Guide along the penciled cutting line
so that the kerf falls into the waste or surplus material. Fig.T
shows the saw in the parallel cutting position relative to the
guide rail. Fig.U shows the saw in the bevel cutting position
relative to the guiderail.
1. Undo the screw inside the rail adjuster to allow for
adjustment between the saw and the guiderail.
2. Retract the lower guard and place the unit on the guide rail,
ensuring the blade is in the highestposition.
3. Rotate the adjuster until saw locks on guiderail.
IMPORTANT: Make sure the saw is securely attached to the
rail by trying to push the saw forward. Ensure there is no
movement of thesaw.
4. Rotate the adjuster back slightly until saw slides easily along
therail.
5. Hold the rail adjuster in position and tighten the
screwagain.
NOTE: ALWAYS adjust the system for use with otherrails.
The rail adjusters are now set up to minimise sideways deviation
when cutting with the saw on the guiderail.
Before using the saw, the anti‑splinter guard
38
on
the guide rail will need tuning in. Refer to Tuning the
Anti‑SplinterGuard.
Tuning the Anti-Splinter Guard (Fig.N)
The guide rail
35
is equipped with an anti‑splinter guard
38
that has to be tuned to the saw before the firstuse.
The anti‑splinter guard
38
is situated on each edge of the
guide rail (Fig.N). The purpose of this anti‑splinter guard is to
provide the user with a visible blade cut line while reducing
the chipping that occurs along the workpiece cut edge
duringcutting.
IMPORTANT: ALWAYS read and follow the Setting
the Circular Saw to the Guide Rail before cutting the
splinterguard!
Steps to Tune the Anti-Splinter Guard (Fig.O–R)
1. Place the guide rail
35
on a scrap piece of wood
39
with
a minimum length of 100mm overhanging the workpiece
(Fig. O). Use a clamp to ensure that the guide rail is securely
attached to the workpiece. This will ensureaccuracy.
2. Set the unit to a 20mm depth ofcut.
3. Place the front of the saw on the overhang end of the guide
rail, making sure that the blade is positioned in front of the
rail edge (Fig.P).
4. Turn the saw on and slowly cut the splinter guard along the
full length of the rail in one continuous operation. The edge
of the splinter guard now corresponds exactly to the cutting
edge of the blade (Fig.Q).
To tune in the anti‑splinter guard on the other side of the guide
rail, remove the saw from the rail and rotate the rail 180°.
Repeat steps 1through4.
NOTE: If desired, the splinter guard can be bevelled to 45°,
then repeat steps 1through 4. This allows one side of the rail for
cutting parallel cuts and the other side of the rail is tuned in for
45° bevel cuts (Fig.R).
NOTE: If the anti‑splinter guard is tuned in for parallel cutting
on both sides, then when the unit is bevelled, the blade will not
run true to the edge of the anti‑splinter guard. This is because
the pivot point of the unit bevel is not stationary and the blade
moves out over when the unit isbevelled.
