INTENDED USE

This tool is intended for lengthways and crossways cutting of
wood with straight cuts as well as angle cuts to 45°; with the
appropriate saw blades also non-ferrous metals, light build-
ing materials and plastics can be cut

SAFETY
WARNING! Read all instructions. Failure to follow all in-
structions listed below may result in electric shock, fi re
and/or serious injury.
DANGER
• Keep hands away from cutting area and the blade;
keep your second hand on front handle (if both hands
are holding the saw, they can not 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 piece being cut in your hands or across
your leg (it is important to support the work properly
to minimize body exposure, blade binding, or loss of
control)
• Hold 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 tool
"live" and shock the operator)
• When ripping always use a rip fence or straight edge
guide (this improves the accuracy of cut and reduces the
chance for blade binding)
• Always use blades with correct size and shape
of arbor holes (diamond or round) (blades that do
not match the mounting hardware of the saw will run
eccentrically, causing 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
• Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator
• When the blade is pinched or bound 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 towards operator
KICKBACK - OPERATOR PREVENTION
Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below
• Maintain a fi rm 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
backwards, but kickback forces can be controlled by the
operator, if proper precautions are taken)
• When 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 backwards while the blade is
in motion or kickback may occur (investigate and take
corrective actions to eliminate the cause of blade binding;
avoid cutting nails or screws)
• When restarting a saw in the workpiece, centre the
saw blade in the kerf and check that saw teeth are
not engaged into the material (if saw blade is binding, it
may walk up or kickback 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 a dull or damaged blade (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 cut (if blade
adjustment shifts while cutting, it may cause binding and
kickback)
• Use extra caution when making a plunge cut into
existing walls or other blind areas (the protruding blade
may cut objects that can cause kickback)
WARNING
• Check lower guard for proper closing before each
use
• Do not operate the saw if lower guard does not
move freely and close instantly
• Never clamp or tie the lower guard into the open
position
• If saw is accidentally dropped, 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 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 (lower guard may operate
sluggishly due to damaged parts, gummy deposits, or a
