1. Make sure that the tool is only connected to the voltage
marked on the name plate.
2. Never use the tool if its cover or any bolts are missing. If
the cover or bolts have been removed, replace them
prior to use.
Maintain all parts in good working order.
3. Always secure the tool when working in elevated
positions.
4. Never touch the blade, drill bit, grinding wheel or other
moving parts during use.
5. Never start the tool when its rotating component is in
contact with the work piece.
6. Never lay the tool down before its moving parts have
come to a complete stop.

ACCESSORIES:
The use of accessories or attachments
other than those recommended in this manual might
present a hazard.

REPLACEMENT PARTS:
When servicing use only
identical replacement parts.
INSTRUCTIONS FOR SAFE HANDLING
a) Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or motor
housing.
If both hands are holding the saw, they cannot
be cut by the blade.
b) Do not reach underneath the workpiece.
The guard
cannot protect you from the blade below the workpiece.
c) 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.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform.
It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
e) Hold power 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
power tool "live" and shock the operator.
f) When ripping always use a rip fence or straight edge
guide.
This improves the accuracy of cut and reduces
the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that
do not match the mounting hardware of the saw will run
eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers or
bolt.
The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
i) 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 lower guard lever and make sure it moves freely
and does not touch the blade or any other part, in all
angles and depths of cut.
j) 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
build-up of debris.
k) Lower guard should be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts." Raise lower guard by lower guard lever and as
soon as blade enters the material, the lower guard
must be released.
For all other sawing, the lower guard
should operate automatically.
l) Always observe that the lower guard is covering the
blade before placing saw down on bench or floor.
An
unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is released.
− 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 toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below.
a) Maintain a firm 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.
b) 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 backward while the blade is
in motion or kickback may occur.
Investigate and take
corrective actions to eliminate the cause of blade binding.
c) 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.
d) Support large panels to minimise 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.
e) Do not use dull or damaged blades.
Unsharpened or
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f) 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.
g) 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.
