Prior to Operation

WARNING:
• Install the appropriate saw blade. Do not use excessively worn
blades. The maximum rotation speed of the tool must not exceed
that of thesawblade.
• Do not attempt to cut excessively smallpieces.
• Allow the blade to cut freely. Do notforce.
• Allow the motor to reach full speed beforecutting.
• Make sure all locking knobs and clamp handles aretight.
• Secure theworkpiece.
• Although this saw will cut wood and many nonferrous
materials,these operating instructions refer to the cutting of wood
only. The sameguide-lines apply to the other materials. Do not cut
ferrous (iron and steel) materials or masonry with this saw! Do not
use any abrasivediscs!
• Make sure to use the kerf plate. Do not operate the machine if the
kerf slot is wider than 10mm.
• Placing the workpiece on a piece of wood will increase the
capacities to 300mm.
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.
The attention of UK users is drawn to the “woodworking machines regulations
1974” and any subsequentamendments.
Ensure the machine is placed to satisfy your ergonomic conditions in terms
of table height and stability. The machine site shall be chosen so that the
operator has a good overview and enough free surrounding space around
the machine that allows handling of the workpiece without anyrestrictions.
To reduce effects of increased vibration, make sure the environment is not
too cold, the machine and accessory are well maintained and the workpiece
size is suitable for thismachine.
Switching On and Off (Fig.A)
The lock off switch
29
located on the the on/off trigger switch
1
must be
flipped in order for the saw to turnon.
1. To run the tool, flip the lock off switch
29
and press the on/off trigger
switch
1
.
2. To stop the tool, release thetrigger switch. The lock off switch will
re-engageautomatically.
Use of XPS™ LED Worklight System (Fig.A,R)
NOTE: The mitre saw must be connected to a powersource.
The XPS™ LED Worklight System is activated by engaging the trigger or
pressing the XPS button
34
on top of the saw housing.
To cut through an existing pencil line on a piece ofwood:
1. With the XPS light on, pull down on the operating handle
3
to bring
the saw blade
8
close to the wood. The shadow of the blade will
appear on thewood.
2. Align the pencil line with the edge of the blade’s shadow. You may
have to adjust the mitre or bevel angles in order to match the pencil
lineexactly.
Your saw is equipped with a battery fault feature. The XPS™ worklight
begins to flash when the battery is near the end of its useful charge, or
when the battery is too hot. Charge the battery prior to continuing cutting
applications. Refer to Charging A Battery for battery charginginstructions.
