INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Always let the Trigger (36) rest in its “OFF” position, remove
the Battery (37) from the tool, and unplug the Charger (39) from its electrical
outlet before performing any inspection, maintenance, or cleaning.
2. Before each use: Inspect the general condition of the Impact Wrench. Check for
misalignment or binding of moving parts, cracked or broken parts, leaking Battery,
damaged Charger wiring, chipped or broken sockets, and any other condition that
may affect its safe operation. If abnormal noise or vibration occurs, have the prob-
lem corrected before further use.
Do not use damaged equipment.
3. Daily: With a clean cloth, remove all dirt, grease, and oil from the Impact Wrench.
Do not immerse the Impact Wrench in any liquids.
4. It may become necessary at sometime to replace or clean the two Carbon Brushes
(29) when the Motor performance decreases, or stops working completely.
To replace the Carbon Brushes: Remove the two Brush Holder Caps (28). Then,
remove the two Carbon Brushes (29), keeping track of the orientation and location
of each. If either Carbon Brush is worn more than halfway, replace
both
Carbon
Brushes. If the Carbon Brushes are just dirty, however, they may be cleaned by
rubbing them with a pencil eraser. If cleaning and replacing used brushes, try to
install them in the same holders and in the same direction they were removed. When
installing the Carbon Brushes, make sure the carbon portion of the Carbon Brushes
contact the Motor’s Rotor and that the springs face away from the Motor. Also, make
sure the springs operate freely. After replacement or cleaning, replace the two Brush
Holder Caps.
NOTE: New Carbon Brushes tend to arc or spark when first used until they wear
and conform to the Motor’s Rotor.
5. CAUTION! All maintenance, service, or repairs not listed in this manual
are only to be attempted by a qualified service technician.
