ADJUSTMENTS
8. Remove the mechanism from the fluid and rotate the
Adjustment Screw clockwise until it stops.
9. Thread the Oil Plug with the Oil Plug Seal and Seal
Support into the mechanism until it is snug.
10. Wipe the outside of the mechanism dry and clean and
remove the Oil Chamber Plug. Using the syringe,
withdraw 0.9 cc of fluid from 1100PS4 models and
1.5 cc from 1900PS4 models.
11. Install the Oil Chamber Plug and tighten it between 20
and 25 in–lb (2.3 and 2.8 Nm) torque.
12. Position a new Hammer Case Gasket on the Motor
Housing and install the assembled mechanism on the
rotor shaft.
13. Place the Hammer Case Cover over the Drive Shaft
against the Housing and Gasket. Install the three
Hammer Case Cap Screws and Lock Washers. Tighten
each Screw between 45 an 50 in–lb (5.1 and 5.6 Nm)
torque.
14. Test the tool for torque at maximum, minimum and
mid–range torque settings. If the tool does not perform
satisfactorily, repeat the refill procedure and pay
particular attention to removing unwanted air from the
fluid system. Refer to the section TORQUE
ADJUSTMENT for specific adjustment procedures.
15. If the torque is satisfactory but the tool fails to shut off,
only then, is it necessary to adjust the shutoff
mechanism. If it should become necessary, proceed as
follows:
a. Remove the Adjusting Hole Plug from the
Hammer Case.
b. Using a pointed probe, pick the paint out of the
wrench opening in the Adjustment Screw that
is 180 degrees away from the Torque Adjustment
Screw.
c. Rotate the Screw counterclockwise not more than
ten degrees.
Before operating the tool, mark the shutoff
Adjustment Screw with a permanent marker or
paint so that it can be distinguished for future
adjustments.
d. Permanently mark the Screw for future
identification and then retest the tool. Adjustments
to the shutoff mechanism should only be made in
five to ten degree increments.
