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.
3. 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.
4. Lower guard should be retracted manually
only for special cuts such as "Pocket 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.
5. 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.
6. 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.
7. 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 make exposed metal
parts of the tool "live" and shock the operator.
8. When ripping always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance for blade binding.
9. 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.
10. Never use damaged
washers or bolts. The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.
11. 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
or incorrect blade
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. 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 as shown
in Fig. 1.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the
saw on the workpiece, the saw should be rested on
the larger portion and the smaller piece cut off.
Fig.1
To avoid kickback, do support
board or panel near the cut.
