WARNING
To avoid injury, follow all applicable safety
instructions, when cutting non-ferrous metals:
• Use only saw blades specifically recommended for
non-ferrous metal cutting.
• Do not cut metal workpieces that must be hand held. Clamp
workpieces securely.
• Cut non-ferrous metals only if you are under the
supervision of an experienced person and the dust bag has
been removed from the saw.
WHEN SAW IS RUNNING
WARNING
Do not allow familiarity from frequent use
of your mitre saw to result in a careless mistake.
A careless fraction of a second is enough to cause a
severe injury.
Before cutting, if the saw makes an unfamiliar noise or vi-
brates, stop immediately. Turn the saw OFF. Unplug the saw.
Do not restart until finding and correcting the problem.
BODY AND HAND POSITION (FIG. S)
WARNING
Never place hands near the cutting area.
Proper positioning of your body and hands when oper-
ating the mitre saw will make cutting easier and safer.
Keep children away. Keep all visitors at a safe distance
from the mitre saw. Make sure bystanders are clear of
the saw and workpiece. Don’t force the saw. It will do
the job better and safer at its designed rate.
Starting a cut:
• Place hands at least 6-3/4 in. away from the path of the
blade – out of the “no-hands zone” (1). (Fig. S)
• Hold workpiece firmly against the fence to prevent
movement toward the blade.
• With the power switch OFF, bring the saw blade down to
the workpiece to see the cutting path of the blade.
• Press in lock-off switch in trigger switch handle.
• Squeeze trigger switch to start saw.
• Lower blade into workpiece
with a firm downward motion.
Finishing a cut:
• Hold the cutting arm in
the down position.
• Release trigger switch
and wait for all moving
parts to stop before
moving your hands and
raising the cutting arm.
• If the blade doesn’t
stop within 6 seconds,
unplug the saw and
follow the instructions in
TROUBLESHOOTING
GUIDE section.

TURNING SAW ON (FIG. T)
To reduce the likelihood of accidental starting, a thumb acti-
vated lock-OFF switch is located on top of the switch handle.
The lock-OFF switch (1) must be pushed in before the trigger
switch (2) can be activated and the mitre saw started.
WARNING
Make the switch child-proof. Insert a
padlock through the hole (3) in the trigger switch and
lock it. This will prevent children and other unauthorized
users from engaging the trigger switch ON.
