SECTION 6 - TORQUE ADJUSTMENT OPERATION

The screwdriver tightens a screw until the torque level set by the torque adjusting
ring is reached. When the torque level is reached, power is automatically
removed from the motor. To adjust the screwdriver's torque, follow the procedure
outlined below:
1. Increase or decrease the torque level by rotating the torque adjusting ring by
hand. Rotating the ring clockwise to a higher number increases the torque level.
Rotating the torque adjusting ring counterclockwise to a lower number decreases
the torque level.
2. Check the new torque level with a torque meter. The torque should be
checked for each job because a number of factors affect the torque output from
one job to another. The final torque level should be set using the actual job
pieces through a series of gradual torque increases. You should always start
below the desired torque level and work upward.
3. Since the torque output value is less than 9 in-lb, the torque of the SKD-2000,
SKD-2200 and SKD-2300 series screwdrivers can be measured with our KTM-
10/A Torque Meter. For the SKD-5200 and SKD-5300 series screwdrivers the
KTM-100/A Torque Meter is required because of the larger torque output values.
4. After using a torque meter to measure and adjust the torque of the
screwdriver, you may want to install a torque fixing ring accessory around the
torque adjusting ring. The torque fixing ring simply screws onto the housing of the
screwdriver. The torque fixing ring prevents operators from re-adjusting the
torque of the screwdriver. For further adjustments, the torque fixing ring must
first be removed.
5. Sometimes the Reverse "R" torque required to remove (Dis-Assembly) a
screw is larger than the torque that was used to tighten that screw. If the
tightened screw will not loosen easily, the clutch may skip or slip. If slipping does
occur, you must reset the screwdriver torque to a higher value to loosen the
screw.
