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
USB010-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to rotary hammer 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.
Wear ear protectors when using the tool
for extended periods. Prolonged exposure
to high intensity noise can cause hearing
loss.
3.
Wear a hard hat (safety helmet), safety
glasses and/or face shield. Ordinary eye
or sun glasses are NOT safety glasses. It
is also highly recommended that you wear
a dust mask and thickly padded gloves.
4.
Be sure the bit is secured in place before
operation.
5.
Under normal operation, the tool is
designed to produce vibration. The
screws can come loose easily, causing a
