SAFETY: General Rules
12. USE SAFETY GLASSES. Also use face or
dust mask if cutting operation is dusty.
As with all power tools there is a certain amount of
hazard involved with the operation and use of the
tool. Use the tool with the respect and caution demanded where safety precautions are concerned.
This will considerably lessen the possibility of personal injury. When normal safety precautions are
overlooked or completely ignored, personal injury
to the operator can result.
1. KNOW YOUR TOOL. Read the owner’s
manual carefully. Learn the tools applications and
limitations, as well as the specific potential hazards peculiar to it.
2. KEEP GUARDS IN PLACE and maintained
in working order.
3. GROUND ALL TOOLS. If tool is equipped
with three-prong plug, it should be plugged into a
three-hole electrical receptacle. If an adapter is
used to accommodate a two-prong receptacle, the
adapter plug must be attached to a known ground.
Never remove the third prong.
4. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from
tool before turning it on.
5. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
6. AVOID DANGEROUS ENVIRONMENT.
Don’t use power tools in damp or wet locations, or
expose them to rain. Keep work area well lighted.
7. KEEP CHILDREN AND VISITORS AWAY. All
children and visitors should be kept a safe distance
from work area.
8. MAKE WORKSHOP CHILDPROOF - with
padlocks, master switches, or by removing starter
keys.
9. DON’T FORCE TOOL. It will do the job bet-
ter and be safer at the rate for which it was designed.
10. USE RIGHT TOOL. Don’t force tool or attachment to do a job it was not designed for.
11. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, or jewelry that can
get caught in moving parts. Nonslip footwear is
recommended. Wear protective hair covering to
contain long hair.

13. SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than using your
hand and frees both hands to operate tool.
14. DON’T OVERREACH. Keep your proper foot-
ing and balance at all times.
15. MAINTAIN TOOLS IN TOP CONDITION.
Keep tools sharp and clean for best and safest performance. Follow instructions for lubricating and
changing accessories.
16. DISCONNECT TOOLS before servicing and
when changing accessories such as chisel and bit.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended accessories. The use of improper accessories may
cause hazards.
18. AVOID ACCIDENTAL STARTING. Make sure
switch is in “OFF” position before plugging in cord.
19. NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the cutting tool
is accidentally contacted.
20. CHECK DAMAGED PARTS. Before further
use of the tool, a guard or other part that is damaged should be carefully checked to ensure that it
will operate properly and perform its intended function - check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced.
21. NEVER LEAVE TOOL RUNNING UNAT-
TENDED. TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.
22. DRUGS, ALCOHOL, MEDICATION. Do not
operate tool while under the influence of drugs, alcohol, or any medication.
23. ADDITIONAL HEALTH HAZARDS. Some
dust created by power sanding, sawing, grinding,
drilling and other construction activities contains
chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
* Lead from lead-based paint.
* Crystalline silica from bricks and cement and
other masonry products
* Arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals, work in a wellventilated area, and work with approved safety
equipment, such as those dust masks that are specifically designed to filter out microscopic particles.
SAFETY: Specific Rules
5. Make sure the abrasive belt is tracking properly.
6. Support your workpiece with the work table.
7. When front work table is to be used at an incline, check that the work table is firmly fixed on
the machine.
1. Before you turn on the machine, make sure
everyone is clear of it. Keep hands away from
abrasive belt.
2. Never remove safety guards during operation.
