General safety instructions:
1. REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see that keys and adjusting wren-
ches are removed from tool before turning it on.
2. KEEP WORK AREA CLEAN. Cluttered areas and ben-
ches invite accidents.
3. DON'T USE IN DANGEROUS ENVIRONMENT. Don't
use power tools in damp or wet locations, or expose
them to rain. Keep work area well lighted.
4. KEEP CHILDREN AWAY. All visitors should be kept safe
distance from work area.
5. MAKE WORKSHOP KID PROOF with padlocks, master
switches, or by removing starter keys.
6. DON'T FORCE TOOL. It will do the job better and safer
at the rate for which it was designed.
7. USE RIGHT TOOL. Don't force tool or attachment to
do a job for which it was not designed.
8. USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersi-
zed cord will cause a drop in line voltage resulting in
loss of power and overheating. Table 1 shows the cor-
rect size to use depending on cord length and name-
plate ampere rating. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the
cord.
Exception No. 1: The reference to the table and the
table itself may be omitted if a statement indicating
the appropriate gage and length is incorporated into
the instruction.
Exception No. 2: The information regarding extension
cords need not be provided for a permanently
connected tool.
9. WEAR PROPER APPAREL. Do not wear loose clo-
thing, gloves, neckties, rings, bracelets, or other jewel-
ry which may get caught in moving parts. Non-slip
footwear is recommended. Wear protective hair cover-
ing to contain long hair.
Exception: The reference to gloves may be omitted
from the instructions for a grinder.
10. ALWAYS USE SAFETY GLASSES. Also use face or
dust mask if cutting operation is dusty. Everyday
eyeglasses only have impact resistant lenses, they are
NOT safety glasses.
11. SECURE WORK. Use clamps or a vise to hold work
when practical. It's safer than using your hand and it
frees both hands to operate tool.
12. DON'T OVERREACH. Keep proper footing and
balance at all times.
13. MAINTAIN TOOLS WITH CARE. Keep tools sharp and
clean for best and safest performance. Follow instruc-
tions for lubricating and changing accessories.
14. DISCONNECT TOOLS before servicing; when chan-
ging accessories, such as blades, bits, cutters, and
the like.
15. REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure switch is in off position before plugging in.
16. USE RECOMMENDED ACCESSORIES. Consult the
owner's manual for recommended accessories. The
use of improper accessories may cause risk of injury
to persons.
17. NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the cutting tool is unintentionally
contacted.
18. CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate pro-
perly 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 pro-
perly repaired or replaced.
19. DIRECTION OF FEED. Feed work into a blade or cut-
ter against the direction of rotation of the blade or
cutter only.
20. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
POWER OFF. Don't leave tool until it comes to a com-
plete stop.
