READ ALL INSTRUCTIONS

1.

KNOW YOUR POWER TOOL. 

Read owner's

manual carefully. Safe operation of this power
tool requires that you read and understand this
owner's manual and all labels affixed to the tool.
Learn its applications and limitations as well as
the specific potential hazards related to this tool.

2.

GUARD AGAINST ELECTRICAL SHOCK.

Prevent body contact with grounded surfaces.
For example: Pipes, radiators, ranges,
refrigerator enclosures.

3.

KEEP GUARDS IN PLACE 

and in good working

order.

4.

KEEP THE WORK AREA CLEAN. 

Cluttered

work areas and work benches invite accidents.

5.

DON'T USE IN DANGEROUS ENVIRONMENTS.

Don't use power tools in damp or wet locations
or expose them to rain. Keep the work area well
lit.

6.

KEEP CHILDREN AND VISITORS AWAY
FROM POWER TOOLS. 

Do not let visitors

contact tool or extension cord. All visitors should
wear safety glasses and be kept a safe distance
from work area.

7.

STORE IDLE TOOLS. 

When not in use tools

should be stored in a dry and high or locked-up
place — out of the reach of children.

8.

DON'T FORCE THE TOOL. 

It will do the job

better and safer at the rate for which it was
designed.

9.

USE THE RIGHT TOOL. 

Don't force a small tool

or attachment to do the job of a heavy duty tool.
Don't use the tool for a purpose not intended —
for example — A circular saw should never be
used for cutting tree limbs or logs.

10.

WEAR PROPER APPAREL.

 Do not wear loose

clothing, neckties, rings, bracelets, or other
jewelry that can get caught in the tool's moving
parts and cause personal injury. Rubber gloves
and nonskid footwear are recommended when
working outdoors. Wear protective hair covering
to contain long hair and keep it from being drawn
into air vents or getting caught in rotating parts.

11.

ALWAYS WEAR SAFETY GLASSES. 

Everyday

eyeglasses have only impact-resistant lenses;
they are 

NOT

 safety glasses.

12.

PROTECT YOUR LUNGS. 

Wear a face or dust

mask if operation is dusty.

13.

PROTECT YOUR HEARING. 

Wear hearing

protection during extended periods of operation.

14.

DON'T ABUSE THE CORD. 

Never carry the

tool by its cord or yank the cord to disconnect it
from the receptacle. Keep the cord from heat, oil
and sharp edges.

15.

SECURE THE WORK. 

Use clamps or a vise to

hold the work when practical. It's safer than using
your hand and it frees both hands to operate the
tool.

16.

DON'T OVERREACH. 

Keep proper footing and

balance at all times. Do not use on a ladder or
unstable support.

17.

MAINTAIN TOOLS WITH CARE. 

Keep tools

sharp and clean for best and safest performance.
Follow instructions for lubricating and changing
accessories.

18.

DISCONNECT TOOLS. 

When not in use, before

servicing, or when changing attachments, blades,
bits, cutters, etc., all tools should be disconnected
from power supply.

19.

REMOVE ADJUSTING KEYS AND WRENCHES.

Get in the habit of checking to see that keys and
adjusting wrenches are removed from the tool
before turning it on.

20.

AVOID ACCIDENTAL STARTING. 

Don't carry

plugged-in tools with finger on switch. Be sure
the switch is off when plugging in.

21.

 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 undersized
cord will cause a drop in line voltage resulting in
loss of power and overheating. A wire gage size
(A.W.G.) of at least 14 is recommended for an
extension cord 50 feet or less in length. A cord
exceeding 100 feet is not recommended. If in
doubt, use the next heavier gage. The smaller the
gage number, the heavier the cord.

22.

OUTDOOR USE EXTENSION CORDS.

 When

tool is used outdoors, use only extension cords
suitable for use outdoors. Outdoor approved
cords are marked with the suffix W-A, for
example - SJTW-A or SJOW-A.
