Air Supply Requirements
The 2955B2 requires an air system capable of supporting a large pneumatic impact wrench.
Before using the tool, make sure you have:
- 1/2-inch NPT fitting

- 90 psi operating air pressure
- An air supply capable of providing the required airflow
Insufficient airflow or pressure can reduce tool performance even when the compressor itself is operating normally.

The tool requires:
- 8–12 drops of IR #10 Air Tool Oil through the air inlet before each use
- Impact-mechanism lubrication according to the required operating interval
Note: The maintenance interval is based on actual tool runtime, not simply elapsed calendar time.

I was informed by my distributer that the #170 IR grease has been discontinued. What grease can we use for our 2925 Impact guns suggested by Ingersoll Rand ? Replacement has to match SG-0.88, ISO VG-40
Thanks,
SIrak
