SPECIFIC SAFETY RULES
GEB003-2
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to hammer drill safety rules. If you use this power
tool unsafely or incorrectly, you can suffer serious
personal injury.
1.
Wear ear protectors with impact drills. Exposure
to noise can cause hearing loss.
2. Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
3. Hold power 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.
4. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
5. Hold the tool firmly with both hands.
6. Keep hands away from rotating parts.
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the bit or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
9. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
SAVE THESE INSTRUCTIONS.
