An adapter Fig. “B” and “C” is available for connecting Fig. “A” type plugs to two-prong

nected to a permanent ground, such as a properly grounded outlet box.
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
breakdown or accident. Check tightness
of screws carefully before operation.
6.
In cold weather or when the tool has not
been used for a long time, let the tool
warm up for a while by operating it under
no load. This will loosen up the lubrica-
tion. Without proper warm-up, hammering
operation is difficult.
7.
Always be sure you have a firm footing.
Be sure no one is below when using the
tool in high locations.
