USE PROPER EXTENSION CORD

. Make

sure your extension cord is in good condi-
tion. Conductor size should be in accor-
dance with the chart below. The amperage
rating should be listed on the motor or tool
nameplate. An undersized cord will cause
a drop in line voltage resulting in loss of
power and overheating. Your extension
cord must also contain a ground wire and
plug pin. Always repair or replace exten-
sion cords if they become damaged. 

Minimum Gauge for Extension Cords

10. WEAR PROPER APPAREL.

Do not wear

loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Non-slip footwear
is recommended. Wear protective hair cov-
ering to contain long hair.

11. 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.

12. SECURE WORK.

Use clamps or a vise to hold

work when practical. It is safer than using your
hand and frees both hands to operate tool.

13. DO NOT OVER-REACH.

Keep proper

footing and balance at all times.

14. MAINTAIN TOOLS WITH CARE.

Keep

tools sharp and clean for best and safest
performance. Follow instructions for lubri-
cating and changing accessories.

15. USE RECOMMENDED ACCESSORIES.

Consult the owner’s manual for recom-
mended accessories. The use of improper
accessories may cause risk of injury.

Safety Instructions For Power Tools

16. REDUCE THE RISK OF UNINTENTION-

AL STARTING.

On machines with magnet-

ic contact starting switches there is a risk of
starting if the machine is bumped or jarred.
Always disconnect from power source
before adjusting or servicing. Make sure
switch is in OFF position before reconnecting.

17. MANY WOODWORKING TOOLS CAN

“KICKBACK” THE WORKPIECE

toward the

operator if not handled properly. Know what
conditions can create “kickback” and know
how to avoid them. Read the manual accom-
panying the machine thoroughly.

18. CHECK DAMAGED PARTS.

Before fur-

ther use of the tool, a guard or other part
that is damaged should be carefully
checked to determine that it will operate
properly and perform its intended function.
Check for alignment of moving parts, bind-
ing 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.

19. NEVER LEAVE TOOL RUNNING UNAT-

TENDED. TURN POWER OFF.

Do not

leave tool until it comes to a complete stop.

20. NEVER OPERATE A MACHINE WHEN

TIRED, OR UNDER THE INFLUENCE OF
DRUGS OR ALCOHOL. 

Full mental alert-

ness is required at all times when running a
machine.

21. NEVER ALLOW UNSUPERVISED OR

UNTRAINED PERSONNEL TO OPER-
ATE THE MACHINE. 

Make sure any

instructions you give in regards to machine
operation are approved, correct, safe, and
clearly understood.

22. IF AT ANY TIME YOU ARE EXPERIENC-

ING DIFFICULTIES

performing the intend-

ed operation, stop using the machine! Then
contact our service department or ask a
qualified expert how the operation should
be performed.
