f.
When ripping always use a rip fence or straight edge guide. This improvesthe accuracy of cut
and reduces the chance of blade binding.
g.
Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades
that do not match the mounting hardware of the saw will run eccen- tri- cally, 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.
Causes and operator prevention of kickback:
a.
Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, caus- ing an
uncontrolled saw to lift up and out of the workpiece toward the opera- tor;
b.
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;
c.
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.
d.
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.
e.
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 com- plete stop. Never attempt to
remove the saw from the work or pull the saw back- ward while the blade is in motion or
kickback may occur.
f.
When restarting a saw in the work-piece, centre the saw blade in the kerf and check that saw
teeth are not engaged into the material.
g.
Support large panels to minimize the risk of blade pinching and kickback.
h.
Do not use dull or damaged blades. Unsharpened or improperly set blades pro- duce narrow
kerf causing excessive friction, blade binding and kickback.
i.
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 sawing into existing walls or other blind areas. The protruding blade
may cut objects that can cause kickback.

Lower guard function
a.
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.
b.
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.
c.
The lower guard may be retracted manually only for special cuts such as "plunge cuts and
compound cuts" . Raise the lower guard by retracting the handle and as soon as the blade
enters the material, release the lower guard. For all other sawing operations, the lower guard
should operate automatically.
