Operating the Tool
1.
Select a bit. Retract the bit collar. Insert the bit and release the retracted collar. To avoid
damaging fasteners, make sure the proper bit is suitable for the head of the fastener.
2.
Rotate the torque adjustment nut to set the torque limit. Turn clockwise to increase torque
and counter clockwise to decrease torque.The scale adjacent to the Torque Adjustment
Nut is a reference guide. The torque output from the driver can change depending on
various fastening factors like friction, type of joint, and the type material being used like a
washer.
3. Make sure the FOR/STOP/REV switch is in the “Stop” position. Connect power cord.
4. Turn driver on and check for proper rotation. FOR-clockwise, REV-counterclockwise.
5. To apply torque, squeeze the lever (Push-to-Start models - place light downward pressure
on the nose of the driver). The driver will automatically stop when the preset torque has
been reached. Never run the motor continuously for extended periods. Use tool
intermittently: (example 5 seconds on and 3.5 seconds off).
6. To remove the screw, turn the FOR/REV switch to REV.
Testing Power Tools:
1. Application Method: Use a torque analyzer in “Peak Mode” with a
rotary transducer between the power tool and the actual application.
This is the best way to test since you are using the actual joint
as the test station. You will see the actual torque
applied to the fastener. Caution: Variances in tool
performance may occur do to the addition of the
rotary transducer.
2. Simulated Method: Always use a quality
joint rate simulator (run down adapter)
with a torque analyzer when testing
power tools in a simulated application.
Use Joint rate and Breakaway methods to obtain
most accurate torque readings in a simulated
rundown.
CARE
1. The screwdrivers are a precision torque control
instrument and should be handled with care at all
times.
2. Operate under safe conditions. Do not place in
operation where such objects as hair, strings,
clothing, etc. can become tangled in the rotating bit.
3.
Keep away from moisture. Never use in high
humid, moist or damp environment.
4. Never change the direction of the rotation when
the tool is in use.
5. Never run the motor continuously for extended
periods.
6.
Never lubricate electrical parts.
7.
Check carbon brushes periodically.
8. Avoid continuous cycling over short periods.
9. It is recommended not to use the tool for fastening
applications with long rundown times.
10. Never use the power cord for hanging the tool (use
hanger for it) and don’t carry the tool by the cord.
