by placing the di-
rection-ofrotation
selector
in
the
center position.
2. Insert the bit
into the chuck.
You will hear a
"click" to indicate
that the bit is se-
curely installed in
place.
3. Pull on the bit to check if it installed securely.
REMOVING BITS
1. Lock the trigger switch on the impact driver
by placing the direction-of rotation selector in
the center position.
2. Pull the sleeve towards the front of the tool.
3. The bit should pop out from the chuck auto-
matically, if not, simply pull out the bit.
TIGHTENING AND LOOSENING SCREWS
1. Install the correct bit.
2. Apply just enough pressure to keep the bit
engaged on the screw.
3. Apply minimal pressure to the trigger switch
initially. Increase the speed only when full con-
trol can be maintained.
TIGHTENING AND LOOSENING NUTS AND BOLTS
Variable speed control must be used with cau-
tion for driving nuts and bolts with socket set at-
tachments. The best technique is to start slowly,
increasing speed as the nut or bolt runs down.
Set the nut or bolt snugly by slowing the tool to
a stop. If this procedure is not followed, the tool
will have a tendency to torque or twist in your
hands when the nut or bolt seats.

MAINTENANCE

WARNING: Always wear safety goggles or
safety glasses with side shields during power tool
operations, or when blowing dust. If operation is
dusty, also wear a dust mask.
WARNING: Do not at any time allow brake
fluids, gasoline, petroleum-based products, pen-
etrating oils, etc. to come in contact with plastic
parts. Chemicals can damage, weaken or destroy
plastic, which may result in serious personal injury.
The tool may be cleaned most effectively with
compressed dry air. Always wear safety goggles
when cleaning tools with compressed air.
Avoid using solvents when cleaning plastic
parts. Most plastics are susceptible to damage
15
from various types of commercial solvents and
may be damaged by their use.
Use a clean cloth to remove dirt, dust, oil,
grease, etc.

BEFORE EACH USE

1. Check for damaged, missing, or worn parts.
2. Check for loose screws, misalignment or bind-
ing of moving parts, or any other condition that
may affect the operation.
3. If abnormal vibration or noise occurs, turn the
tool off immediately and have the problem cor-
rected before further use.
