22.

Use only accessories that are recom-
mended by the manufacturer for your
model.

 Accessories that may be suitable for

one tool, may become hazardous when used
on another tool.

SERVICE

23.

Tool service must be performed only by
qualified repair personnel.

 Service or main-

tenance performed by unqualified personnel
could result in a risk of injury.

24.

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.

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 undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-
ber, the heavier the cord.

SPECIFIC SAFETY RULES

USB008-5

DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to circular saw safety
rules. If you use this tool unsafely or incorrectly, you can suffer
serious personal injury.

1.

DANGER! 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.

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 Oper-

ator Prevention of Kickback”)

Do not reach underneath the work.

 The

guard can not protect you from the blade
below the work. Do not attempt to remove cut
material when blade is moving.
CAUTION: Blades coast after turn off. Wait
until blade stops before grasping cut material.
