Section 4. MAINTENANCE & PARTS
FIGURE D-1. ROUTINE MAINTENANCE CHECKLIST
Service intervals are listed as hours/months, whichever occurs first.
Use only IMT’s synthetic compressor oil. The use of any other oil causes excessive carbon buildup, and will void the
warranty on the compressor.
NOTE 1.
Under normal operating conditions, oil changes are required every 3 months. When operating in a dirty environment,
change the oil and air filter more frequently as your particular operating conditions dictate. Oil capacity is 1-1/3 quarts.
NOTE 2.
Cylinder head stud torque MUST be checked after the initial 8-10 hours of operation. The compressor must be cold (room
temperature) before retorquing of studs. Torque studs to 240 in-lbs plus or minus 10 in-lbs.
