ADDITIONAL SPECIFIC SAFETY RULES
SERVICE
1. Tool service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could result in a
risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow
instructions in the Maintenance Section of this manual. Use of
unauthorized parts or failure to follow Maintenance Instructions may create a
risk of electric shock or injury.
1. Keep hands away from cutting area and 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.
2. Keep your body positioned to either side of the saw blade, but not in
line with the saw blade. KICKBACK could cause the saw to jump backwards.
(See "Causes and Operator Prevention of KICKBACK.")
3. Do not reach underneath the work. The guard cannot protect you from
the blade below the work.
4. 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 Handle and
make sure it moves freely and does not touch the blade or any other part, in all
angles and depths of cut.
5. 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.
6. Lower guard should be retracted manually only for special cuts such
as “Pocket Cuts” and “Compound Cuts.” Raise lower guard by Retracting
Handle. As soon as blade enters the material, lower guard must be
released. For all other sawing, the lower guard should operate automatically.
7. 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.
8. NEVER hold piece being cut in your hands or across your Ieg. It is
important to support the work properly to minimize body exposure, blade
binding, or loss of control.
9. Hold tool by insulated gripping surfaces when performing an operation
where the cutting tool may contact hidden wiring. Contact with a “live” wire
will also make exposed metal parts of the tool “live” and shock the operator.
10. When ripping always use a rip fence or straight edge guide. This
improves the accuracy of cut and reduces the chance for blade binding.
11. Always use blades with correct size and shape (diamond vs. round)
arbor holes. Blades that do not match the mounting hardware of the saw will
run eccentrically, causing loss of control.
12. 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 is the result of tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below:
13. 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.
