ADDITIONAL SAFETY RULES FOR HAMMER-DRILLS
1. Apply forward force only on pistol grip handle and ONLY with your
hands when drilling.
2. Do not use bits larger than those recommended. They may cause
personal injury due to jamming and loss of control. Large bits may also
overload the drill and damage the motor and gears.
3. Verify that the mode selecting ring, the speed selector, and the reversing
switch are in correct positions for the operation being performed.
4. Use only percussion-type carbide-tipped bits when hammer-drilling.
5. Always wear ear protectors and safety glasses when hammer-drilling.
6. Do not attempt to cut through reinforcing rods with percussion-type bits.
7. Should the drill bit become jammed in the work, release switch trigger
immediately to prevent personal injury. Remove the battery from the tool and
remove the drill bit from the work. Do not attempt to free the stalled bit by
starting and stopping the motor. This could result in bodily injury.
