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 tool from power source before making
any adjustments or removing/installing attachments or
accessories. Be sure the trigger switch is in the OFF position. An
accidental start-up can causeinjury.
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)
A hole
28
is provided in the on/off switch
1
for insertion of a padlock to
lock thetool.
1. To run the tool, press the on/off switch
1
.
2. To stop the tool, release theswitch.
Use of XPS LED Worklight System (Fig. A, N)

The XPS LED Worklight System is activated with a push button switch, fitted
on the handle under the guard lock release lever
2
. The XPS LED Worklight
System is independent of the mitre saw’s triggerswitch. A failure of XPS has
no effect on the intendedoperation.
To cut through an existing pencil line on a piece ofwood:
1. Push the black plastic lever, then pull down on the operating handle to
bring the saw blade
7
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.
Speed Control Dial (Fig. A)
DWS771 only
The speed control dial
27
can be used for advance setting of the required
range ofspeed.
Turn the speed control dial
27
to the desired range, which is indicated by
a number (1–5).
• Use high speeds for sawing soft materials such aswood.
• Use low speeds for sawinghardwood.
Body and Hand Position (Fig. O)
Proper positioning of your body and hands when operating the mitre saw
will make cutting easier, more accurate andsafer.

WARNING:
• Never place your hands near the cuttingarea.
• Place your hands no closer than 100mm from theblade.
• Hold the workpiece tightly to the table and the fence when cutting.
Keep your hands in position until the switch has been released and
the blade has completelystopped.
• Always make dry runs (without power) before finish
cuts so that you can check the path of theblade.
• Do not cross yourhands.
• Keep both feet firmly on the floor and maintain properbalance.
• As you move the saw arm left and right, follow it and stand slightly
to the side of the sawblade.
