Before each use
1. Inspect the hammer drill, the trigger switch, the cord and the accessories for damage.
2. Check for damaged, missing, or worn parts.
3. Check for loose screws, misalignment or binding of moving parts, or any other condition that may
affect the operation.
4. If abnormal vibration or noise occurs, turn the tool off immediately and have the problem corrected
before further use. Unplug the tool from
the
power source before cleaning or performing any maintenance.
Using compressed air may be the most effective cleaning method. Always wear safety goggles when
cleaning tools using compressed air.
Removing the chuck (Fig. 8)
1. Unplug the hammer drill from the power source.
2. Open the chuck jaws by turning the sleeve in a counterclockwise direction.
3. Use a Phillips screwdriver (not included) to remove the chuck screw by turning it in a clockwise
direction.
4. Insert a 5/16 in. or larger hex key (not included) into the chuck and securely tighten the chuck jaws
around the hex key.
5. Tap the hex key sharply with a mallet (not included) in a counterclockwise direction. This will loosen
the chuck for easy removal.
NOTICE:
The chuck screw has left-handed threads. Attach a new chuck to the spindle and
tighten the chuck screw.
