1/4 IN. HEX CHUCK
1. Your driver is equipped with a tool-less 1/4 in. hex chuck, so you can quickly change bits
with no extra tools required.
2. Remove the battery pack or place the forward / reverse switch in the middle (neutral –
locked) position.
3. To insert or change bits, pull the chuck locking sleeve (see Parts Identification #7) away from
the tool. Hold it with one hand while inserting the bit with the other hand. Release the locking
sleeve to lock the bit in place.
4. Always make sure that the bit is seated firmly by pulling on the bit. Never attempt to operate
a bit that is wobbly, unstable, or broken.
5. To remove the bit, pull the chuck locking sleeve away from the tool, remove the bit and
release the sleeve.
NOTE:
Only use impact-quality bits with a locking groove.
GENERAL SCREWDRIVING
WARNING! The impact driver is not intended to be used as a drill.
WARNING! The impact driver is not a torque wrench. Do not use this tool for tightening fasteners to
a specific torque.
1. Clamp your work piece.
2. Drill pilot holes for larger screws or when driving screws into hardwoods.

tool do the work.

MAINTENANCE
Before making any adjustments or changing any accessory, turn off the tool and unplug it from its
power source.
1. Check for damaged parts. Before using any tool, any part that appears to be damaged should
be carefully checked to determine that it would operate properly and perform its intended
functions. Check for alignment and binding of moving parts, for broken parts or mounting
fixtures, or for any other condition that may affect proper operation. Any part that is damaged
should be repaired or replaced by a qualified technician.
2. When servicing, use only identical replacement parts. Only use accessories intended for use
with this tool. Replace damaged parts immediately.
3. Keep the tool clean. Wipe the tool with a clean cloth and periodically blow out all areas with
compressed air. If compressed air is not available, use a brush to remove dust from all areas.
Do not use harsh chemicals or solvents to clean the tool. These chemicals could seriously
damage the plastic housing.
CAUTION! Do not at any time let brake fluids, gasoline, petroleum-based products,
penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken
or destroy plastic which may result in serious personal injury.
4. Regularly inspect all mountings and screws to ensure tightness. Should any screws become
loose, tighten immediately.
