SPECIFIC SAFETY RULES
USB010-2
DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to rotary ham-
mer 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.
Con-
tact 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 recom-
mended that you wear a dust mask and thickly
padded gloves.
4.
Be sure the bit is secured in place before opera-
tion.
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 lubrication. 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.
8.
Hold the tool firmly with both hands.
9.
Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
13. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
