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
USB002-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to hammer drill safety
rules. If you use this tool unsafely or incorrectly, you can suffer
serious personal injury.
1.
Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord.
Contact with a “live” wire will
make exposed metal parts of the tool “live”
and shock the operator.
2.
Always be sure you have a firm footing.
Be
sure no one is below when using the tool in
high locations.
3.
Hold the tool firmly with both hands.
Always use the side grip.
4.
Keep hands away from rotating parts.
5.
Do not leave the tool running.
Operate the tool only when hand-held.
6.
Do not touch the bit or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
