MAINTENANCE
The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when
cleaning tools with compressed air. Before each use:
•
Inspect the cordless hammer drill, the variable-speed trigger switch, and the cord for damage.
•
Check for damaged, missing, or worn parts.
•
Check for loose screws, misalignment or binding of moving parts, or any other condition that may
affect the operation.
•
If abnormal vibration or noise occurs, turn the cordless hammer drill off immediately, and have the
problem corrected before further use.
CHUCK REMOVAL
(fig 14)
The chuck can be removed and replaced with a new
one.
1. Lock the variable-speed trigger switch by placing
the direction-of-rotation selector in the centre
position.
2. Open the chuck jaws. Using a screwdriver, remove
the chuck screw by turning it clockwise.
3. Insert a 5/16” (8 mm) or larger hex key into the
chuck of the hammer drill and tighten the chuck
jaws securely.
4. Tap the hex key sharply with a mallet in a counter-clockwise direction. This will loosen the chuck for
easy removal.
5. Attach a new chuck to the spindle and tighten the chuck screw.
