control.
6. 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.
7. Check lower guard for proper closing before each use. Do not operate 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 Lever and make sure it
moves freely and does not touch the blade or any other part, in all angles and
depths of cut.
To check lower guard, open lower guard by hand, then release and watch
guard closure. Also check to see that Retracting Lever does not touch tool
housing. Leaving blade exposed is VERY DANGEROUS and can lead to
serious personal injury.
8. Check the operation and condition 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
buildup of debris.
9. Lower guard should be retracted manually only for special cuts such as
"Plunge Cuts" and "Compound Cuts". Raise lower guard by Retracting Lever.
As soon as blade enters the material, lower guard must be released. For all
other sawing, the lower guard should operate automatically.
10. 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.
11. When ripping always use a rip fence or straight edge guide. This improves the
accuracy of cut and reduces the chance for blade binding.
12. Always use blades with correct size and shape (diamond versus round) arbor
holes. Blades that do not match the mounting hardware of the saw will run
eccentrically, causing loss of control.

13. Never use saw blades made of high-speed steel.
14. 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.
15. Causes and Operator Prevention of Kickback:
— 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 operator.
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 firm grip with both hands on the saw and position your body and arm
to allow you to resist KICKBACK forces. 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
backward while the blade is in motion or KICKBACK may occur. Investigate and
take corrective actions to eliminate the cause of blade binding.
When restarting a saw in the workpiece, center 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.
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
