OPERATION INSTRUCTIONS
Pre-Start Procedures:
1. Inspect the compressor for any damaged components. Do not operate if compressor is
damaged.
2. Check oil level in the compressor pump (See "Checking Oil Level").
3. Verify that the tanks have been drained and are clear of any moisture or dirt (See
"Draining Tank").

GENERAL MAINTENANCE
Service and Maintenance:
Prior to performing service and maintenance to the compressor, always disconnect all
accessories and attachments from the unit and shut off gasoline engine. When replacing
parts, only use Genuine BOSTITCH replacement parts.
Checking the pump Oil Level :
1. Verify that the compressor is turned off and on a level surface.
2. Observe the oil level through the clear sight glass that is located at the base
of the crankcase.
3. If oil is visible to the middle of the sight glass, then the oil level is acceptable.
Changing the Oil: Oil should be changed every 3 months or 300 hours of operation.
1. Verify the compressor is turned Off.
2. Place a small catch basin under the oil drain port (an 8oz. cup will work fine).
3. Remove the oil fill plug.
4. Remove the oil drain plug.
5. Allow the oil to drain into the catch basin - tilting the compressor toward the
drain plug is beneficial.
6. Insert the oil drain plug into the oil drain port.
7. Add 7.5 oz of SAE 40 weight non detergent oil to the crankcase.
8. Insert oil fill plug.
