OPERATION
MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, lubricant, grease, etc.
SETTING DEPTH
See Figures 4 - 5, page 12.
The adjustable nosepiece of the 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 screwdriver bit.
 Test drive a screw in scrap material to determine if it is
correct.
 Adjust as necessary to increase or decrease the desired
depth.
DRIVING SCREWS
See Figures 6 - 7, page 12.
There are two options for gripping the handle of the screw-
driver, determined by operator 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 correct 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 screwdriver. 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.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spack-
ling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes, com-
mutators, etc. Consequently, we do not recommended using
this product for extended work on these types of materials.
However, if you do work with any of these materials, it is ex-
tremely important to clean the product using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
