STARTING/STOPPING THE SCREWDRIVER
To turn the screwdriver ON, depress the switch
trigger. Release the switch trigger to turn the
screwdriver OFF.
VARIABLE SPEED
SWITCH
Your hammer drill has
a variable speed dial
on switch. The speed
is regulated by the
pressure applied to
the switch.
Variable speed is particularly useful when
starting the hammer drill. Also allows you to
set an optimal speed for any kind of job.
LOCK-ON BUTTON
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 button and the screwdriver
will continue running.
To release the lock, depress the switch trigger
and release.
If you have the lock-on feature engaged dur-
ing use and the screwdriver becomes discon-
nected from the power supply, disengage the
lock-on feature immediately.
FORWARD/REVERSE LEVER
The direction of rotation of the bit is controlled
by a lever located above the switch trigger.
With the screwdriver held in normal operat-
ing 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 for-
ward/reverse 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 trig-
ger and allow the screwdriver to stop before
changing its direction.

SETTING DEPTH
The adjustable nosepiece of your tool will
automatically drive screws to preset depths.
It may be helpful to begin each new job by
driving several test screws in scrap material to
check and adjust the depth setting.
To make preset depth adjustments:
· Rotate the adjusting sleeve until you obtain
the desired depth for the bit holder or screw-
driver bit.
· Test drive a screw in scrap material to deter-
mine if it is correct.
· Adjust as necessary to increase or decrease
the desired depth.
DRIVING SCREWS
There are two two options for gripping the
handle of the screwdriver, determined by op-
erator comfort and working angle.
The screwdriver has a variable speed switch for
operator control of speed and torque limits.
· Be sure the screwdriver is in the OFF position
before connecting it to the power supply.
· Check the direction of rotation lever for cor-
rect setting (forward or reverse).
· Secure the workpiece. Use clamps if necessary.
· Plug the screwdriver into power supply
source.
· Depress the switch trigger to start the screw-
driver. Do not lock the switch ON for jobs
where the screwdriver may need to be stopped
suddenly.
· Hold the screwdriver firmly and place the bit
and screw at the point to be driven.
NOTE: The bit holder is magnetized and will
hold most commercial drywall screws.
· Apply quick, snap action type pressure to the
bit. The pressure applied will engage the clutch
and drive the screw.
