ADJUSTMENTS
SETTING THE POWER REGULATOR
Impact wrenches are not torque control devices.
Fasteners with specific torque requirements
must be checked with suitable torque measuring
devices after installation with an impact
wrench.
231G Impact Wrench incorporates a power regulator
into the reverse mechanism that allows the operator to
have either full power output in one direction and
reduced power output in the other direction or full
power output in both directions. To adjust the power,
proceed as follows:
For full power in both directions,
rotate the reverse
valve until the notch on each end of the reverse valve
aligns with the number 5 on each side of the housing.
The numbers 0 thru 5 on
the housing are only for
reference and DO NOT
denote a specific power
output. Zero (0) desig-
nates the lowest power
output while five (5)
denotes the highest.
(Dwg. TPD1247)
For reduced power in the forward direction and
full power in the reverse direction,
push the reverse
valve inward on the right side of the tool and rotate
the reverse valve until the notch on the right side
aligns with the desired number on the right side. This
provides reduced power in forward but full power in
reverse when the reverse valve is pushed in the oppo-
site direction.
See Dwg. TPD1248.

For reduced power in the reverse direction and
full power in the forward direction,
push the
reverse valve inward on the left side of the tool and
rotate the reverse valve until the notch on the left side
aligns with the desired number on the left side. This
provides full power in forward but reduced power in
reverse when the reverse valve is pushed the opposite
direction.
See Dwg. TPD1249.

LUBRICATION
Ingersoll-Rand No. 50
Ingersoll-Rand No. 105
Always use an air line lubricator with these tools.
We recommend the following Filter-Regulator-Lubri-
cator (FRL) Unit:
Inside USA use FRL unit #C28-04-FKG0-28
Outside USA use FRL unit #C28-C4-FKG0
After each forty-eight hours of operation,
or as
experience indicates, inject about 4 cc of the recom-
mended grease into the Grease Fitting (4).
