APPLICATIONS
You may use this product for the purpose listed below:

Driving screws in drywall and wood
STARTING/STOPPING THE SCREWDRIVER
See Figure 2, page 11.
To turn the screwdriver
ON, depress the switch trigger.
Release the switch trigger to turn the screwdriver OFF.
VARIABLE SPEED
The screwdriver has a variable speed switch for operator
control of speed and torque limits.
Depress the switch trigger all the way for maximum speed
and torque. Depress the switch trigger only part of the way
for less speed and torque.
Avoid running the tool at low speeds for extended periods
of time. Constant use at low speeds may cause overheating.
If this occurs, cool the screwdriver by running it without a
load and at full speed.
LOCK-ON BUTTON
See Figure 2, page 11.
The screwdriver is equipped with a lock-on feature which
is convenient for continuous driving of screws for extended
periods of time. To lock-on, depress the switch trigger, push
in and hold the lock-on button located on the side of the
handle, then release switch trigger. Release the lock-on but-
ton and the screwdriver will continue running.
To release the lock, depress the switch trigger and
release.
If you have the lock-on feature engaged during use and the
screwdriver becomes disconnected from the power supply,
disengage the lock-on feature immediately.
FORWARD/REVERSE LEVER
See Figure 3, page 11.
The direction of rotation of the bit is controlled by a lever
located above the switch trigger. With the screwdriver held
in normal operating position, the direction of rotation lever
should be positioned to the left of the switch for forward
driving operation. The direction of rotation is in reverse when
the lever is to the right of the switch.
NOTE: The screwdriver will not run unless the forward/re-
verse lever is pushed fully to the left or right. The design of the
switch will not permit changing the direction of rotation while
the screwdriver is running. Release the switch trigger and
allow the screwdriver to stop before changing its direction.
