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.
