GENERAL INFORMATION

GENERAL REPAIR INSTRUCTIONS

1. Before performing any service operation with the engine mounted, disconnect the grounding cable

from the battery.

This will reduce the chance of cable damage and burning due to short circuiting.

2. Always use the proper tool or tools for the job at hand.

Where specified, use the specially designed tool or tools.

3. Use genuine INGERSOLL-RAND parts.

4. Never reuse cotter pins, gaskets, O-rings, lock washers, and self locking nuts. Discard them as you

remove them. Replace them with new ones.

5. Always keep disassembled parts neatly in groups. This will ensure a smooth reassembly operation.

It is especially important to keep fastening parts separate. These parts vary in hardness and design,

depending on their installation position.

6. All parts should be carefully cleaned before inspection or reassembly.

Oil ports and other openings should be cleaned with compressed air to make sure that they are

completely free of obstructions.

7. Rotating and sliding part surfaces should be lubricated with oil or grease before reassembly.

8. If necessary, use a sealer on gaskets to prevent leakage.

9. Nut and bolt torque specifications should be carefully followed.

10. Always release the air pressure from any machine-mounted air tank(s) before dismounting the engine

or disconnecting pipes and hoses. To not do so is extremely dangerous.

11. Always check and recheck your work. No service operation is complete until you have done this.
