TM 5-3895-374-24-2 PREVENTIVE MAINTENANCE SCHEDULE A   schedule   should   be   set   up   and   followed   for   periodic   inspection   and   maintenance;   the frequency   of   cleaning   will   depend   on   the   conditions   of   operation.      Listed   below   is   the recommended schedule. Daily: 1. Check the circulating oil pump pressure. 2. Check the temperature; the thermometer on the rear of the firebox and the temperature controller readings should be about the same. Monthly:  (More often if necessary) 1. Remove all dust from the control panel. 2. Clean the lens and sight tube on the Mini-Peeper. 3. Clean and adjust the gas pilot assembly. 4. Clean and adjust the tailpiece assembly. 5. Check and, if necessary, adjust the combustion mixture. 6. Observe the fuel gauges for proper pressure. 7. Observe the thermometer and the temperature controller for proper calibration. 8. Simulate flame failure by disconnecting the Mini-Peeper while the burner is operating. Quarterly:  (More often if necessary) 1. Grease the pump and pump motor with a lithium base grease. 2. Check the pump and motor coupling for alignment. 3. Spray the damper motor linkage with WD-40 or equivalent.  Do not use oil or grease on linkage under dusty conditions. 4. Replace the fuel oil filter cartridge. Yearly:  (More often if necessary) 1. Simulate low oil to be sure low oil cutout is functioning. 2. turn the temperature controller to 450° F and observe that the highlimit switch cutout is functioning, 3.
