INSPECTION, MAINTENANCE AND ADJUSTMENT Preventive Maintenance Safety Precautions Periodic checks and replacement of oil, grease, filters, etc. must be made at specific intervals, to keep the machine in good working condition. The following pages describe the items to be checked, the lubricants to be used, and the time interval between each check. 1. Before performing any maintenance checks, move the pilot cutoff switch to the locked posi- tion. Place a warning tag on the controls so that no one begins to operate the machine while the maintenance checks are being performed. NOTE 2. Clean up all fuel spills. Fuel spills are hazardous, especially around the engine.
The time interval between each service check may need to be shortened if the machine is operating in severe atmospheric conditions. Machines working in extremely hot or dusty conditions will require more frequent service checks. The total hours of machine operation are determined by the hour meter that is located on the front instrument panel. 3. Inspect all fuel lines for leakage. Replace any lines, fittings, O-rings, or filters that show signs of wear or damage. 4. If a test procedure requires the engine to be running, keep all unnecessary personnel away from the machine.
