LUBRICATION
Oil:
Ingersoll–Rand No. 50 Oil.
Grease:
Ingersoll–Rand No.67 Grease.
Fluid:
Use only Ingersoll–Rand Fluid Part Number
EQ106S–400–1.
After each 20 000 cycles, or as experience indicates,
drain and refill the Impulse Unit Drive Assembly (36) as
instructed in this manual using the Fluid Replacement Kit
(Part No. EQ106S–K400). Lubricate the hex drive and the
output shaft before assembly.
We recommend the use of an air line lubricator in the air
supply line. Attach the unit as close to the tool as practi-
cal. Where the lubricator cannot be permanently mounted,
we recommend using an Ingersoll–Rand No. L01–02–000
Lubricator. For permanent installations, we recommend
using an Ingersoll–Rand C22–03–G00 Filter–Lubricator–
Regulator Unit. These units have 1/4" pipe tap inlet and
outlet. The L01–02–000 has .25 oz. (7.5 cc) capacity; the
C22–03–G00 has 5 oz. (150 cc) capacity.
TORQUE ADJUSTMENT
To adjust the torque on these Twin Blade Impulse
Wrenches, proceed as follows:
1. Remove the Adjustment Hole Plug (69).
2. Rotate the Drive Shaft (50) until the Torque Adjust-
ment Screw (37) is visible in the opening.
3. Using a 1.5 mm hex wrench, rotate the Adjustment
Screw clockwise to increase the torque output and
counterclockwise to decrease the torque output.
Do not rotate the Oil Plug (58).
Make all final adjustments at the job
4. Replace the Adjustment Hole Plug.
CHANGING THE MECHANISM FLUID
To change the Mechanism Fluid in the Impulse Mecha-
nism, proceed as follows:
1. For model 380PQ1, use a pointed probe to to push
the Spring Seat (75) against the Retaining Sleeve
Spring (74). While the Spring is compressed, use an-
other pointed probe or thin blade screwdriver to re-
move the Retaining Ring (76). Lift the Spring Seat,
Spring and Bit Retaining Sleeve (73) off the Drive
Shaft (50) and remove the Bit Retaining Ball (72).
2.
Remove the Rubber Housing Boot (77).
3.
Using copper–covered vise jaws, carefully grasp the
flats of the Mechanism Cover (67) with the output
end of the Drive Shaft downward.
