OM3020.1 12/99 Operation - Section 3 Operating Instructions Page 3-3 6. Move outboard of the front wheel, and inspect attaching nuts/studs to be sure all are tight and complete. Check tires for cuts, damage or “bubbles” and that inflation appears to be correct. 7. Move behind the rear of the front wheel, inspect for leaks at hub or brakes or any unusual conditions. Inspect wheel speed sensor and harness. Inspect suspension hardware to be sure it is all in place. Inspect live end of steering cylinder for proper greasing, and for security of all parts. Inspect for any hydraulic leaks. 8. Inspect sight glass on hydraulic tank.
With engine stopped and body down, hydraulic fluid must be visible in lower sight glass. 9. Move on around the hydraulic tank and in front of the rear dual tires, inspect the hoist cylinder for any damage and leaks, also that lower guard is in place. Inspect both upper and lower hoist cylinder pins for security, and for proper greasing. 10. Before leaving this position, look under the lower edge of the chassis to be sure the flexible duct that carries the air from the main blower to the final drive housing is in good condition with no holes or breakage. Also look up at the main hydraulic pumps to see that there is no leakage or any other unusual condition with pumps or pump drive shafts. 11.
Move on around the dual tires, check to see that all nuts/studs are in place and tight. Inspect wheel for any leakage that would indicate brake leakage, or wheel motor leakage. Check dual tires for cuts, damage or “bubbles” and that inflation appears to be correct. If truck has been run on a “flat”, the tire must be cooled before parking truck inside . Inspect for any rocks that might be lodged between dual tires, and that rock ejector is in good condition and straight so that it can not damage a tire. 12. Inspect left rear suspension for damage and for correct rod exposure, and that there are no leaks.
See that covers over the chromed piston rod are in good condition and inspect for proper greasing. 13. Open rear hatch cover. Inspect for leaks around the parking brakes, and that there are no rags or tools left behind. Inspect condition of cooling air exhaust ductwork to be certain that it is intact and that there are no obstructions. 14. While standing in front of rear hatch, look up to see that rear lights are in good condition, along with dual backup horns. Look up at panhard rod to see that it is getting proper greasing. Also look at both body hinge pins for greasing and any abnormal condition. Check hoist limit switch and clear any mud/debris from contacts. 15.
Perform the same inspection on the right rear suspension as done on the left. 16. Move on around the right dual tires, inspect between the tires for rocks, and for condition of the rock ejector, inspect the tires for cuts or damage, and for correct inflation. 17. Perform the same inspection for wheel nuts/studs and wheel leaks that was done on the left hand dual wheels. 18. Move in front of right dual tires, and inspect the hoist cylinder the same as was done on the left side. Check security and condition of bodyup limit switch. Remove any mud/dirt accumulation from switch. 19.
Move on around the fuel tank, inspect the fuel quantity gauge, (this should agree with what will show on the gauge in the cab). Inspect the attaching hardware for the fuel tank at the upper saddles, and then at the lower back of the tank for the security and condition of the mounts. Check hoist filters for leaks. 20. Move in behind the right front wheel, and inspect the steering cylinder, suspension attaching hardware and suspension extension, as well as greasing and attaching hardware for the steering cylinder. Inspect the hub and brakes for leaks and any unusual condition. Inspect wheel speed sensor and harness. Be sure the suspension protective boot is in good condition. 21.
Move out and around the right front wheel, inspect that all nuts/studs are in place and tight. 22. Move in behind the front of the right front wheel, check hub and brakes for leaks and any unusual condition. Inspect wheel speed sensor and harness. Inspect steering cylinder for security and for proper greasing. Inspect the engine compartment for any leaks and unusual condition. Inspect the fan guard, and belts also for any rags or debris behind radiator. Turn work light off, if used, and secure the ladder up and latched. 23. Inspect auto lube system. See Maintenance Section 4 for specific details concerning auto lube system. 24.
Move on around to the right front of the truck, drop the air cleaner pans to remove dirt, latch up and secure. Inspect battery box cover for damage and be sure it is in place and secure.
