repetitive motions or uncomfortable positions may
be harmful to your hands and arms. Stop using any
tool if discomfort, tingling feeling or pain occurs.
Seek medical advice before resuming use.

• Always turn off the air supply and disconnect the

air supply hose before installing, removing or

PLACING TOOL IN SERVICE

LUBRICATION

Ingersoll–Rand No. 10. Ingersoll–Rand No. 28.

Always use an air line lubricator with these tools.
We recommend the following Filter–Lubricator–Regulator

Unit:

For USA – No. C22–04–G00
For International – No. C26–04–A29

Motor

Before starting the tool and after each eight hours of
operation, unless the air line lubricator is used, detatch

the air hose and inject 1.5 cc of Ingersoll–Rand No. 10 Oil
into the air inlet.

For models with D, H, J, JJ, K, and L gearing, after
each 50,000 cycles or one month of operation,

whichever comes first, inject approximately 6 cc of
Ingersoll–Rand No. 28 Grease into the Grease Fitting (39).

For models with M, N, or Q gearing, after each 50,000
cycles or one month of operation, whichever comes first,

inject approximately 9 cc of Ingersoll–Rand No. 28
Grease into the Grease Fitting (39).

INSTALLATION

An air line filter can greatly increase the life of an air tool.
The filter removes dust and moisture. Low pressure (under
90 psig; 6.2 bar/620 kPa) reduces the speed of all air tools.
Low air pressure not only wastes time, but also costs
money . High air pressure (over 90 psig; 6.2 bar/620 kPa)
raises performance beyond the rated capacity of the tool
and could cause injury. Be sure all hoses and fittings are
the correct size and are tightly secured.
See Dwg. TPD905–1 for a typical piping arrangement.
