Komatsu — AT THE TRUCK - GROUND LEVEL WALK AROUND INSPECTION

OM3005.1 Operation - Section 3 Operating Instructions Page 3-3 5. Look overhead at bottom of cab and check for leakage of the steering control valve, brake valves, and/or hoses. 15. While standing behind final drive housing, look up to see that rear lights are in good condition, along with back up horn. Inspect anti-sway bar to see that it is getting proper greasing. Also look at both body hinge pins for greasing and any abnormal condition. 6. Move outboard of the front wheel, and inspect attaching lugs/wedges to be sure all are tight and complete. Check tires for cuts, damage or "bub- bles" and that inflation appears to be correct. 16.

Perform the same inspection on the right rear suspension as done on the left. 7. Move behind the rear of the front wheel, inspect for leaks at hub or brakes or any unusual conditions. Inspect suspension hardware to be sure it is all in place. Inspect the tie-rod and steering cylinder for proper greasing, and for security of all parts. Inspect for any hydraulic leaks. 17. Move on around the right dual tires, inspect be- tween the tires for rocks, and for condition of the rock ejector, inspect the tires for cuts or damage, and for correct inflation. 18. Perform the same inspection for wheel lugs/wedges, wheel cover latches, and for leaks that was done on the left hand dual wheels. 8.

Inspect sight glass for transmission oil level. With engine stopped, hydraulic fluid should be visible about half way up in the glass. Also check the transmission filter for leaks. 19. Move in front of right dual tires, and inspect the hoist cylinder the same as was done on the left side. 9. Move to the side of the hydraulic tank and check the hydraulic fluid level in the hydraulic tank. Oil should be visible in sight glass with engine stopped and body down. Inspect the final drive anchor pivot area for evi- dence of proper greasing of the bearing and any evidence of wear or looseness in the pin or bear- ing. 10.

Move on around the hydraulic tank and in front of the rear dual tires, inspect the hoist cylinder for any damage and leaks. Inspect both upper and lower hoist cylinder pins for security, and for proper greasing. 20. Move on around the fuel tank, inspect the fuel breather. 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 condi- tion of the mounts. 11. Before leaving this position, look to see that there is no leakage or any other unusual condition with transmission, drive shaft, or parking brake. On the inside of the frame rail, check the hoist control valve and auxiliary manifold for leakage and security. 12.

Move on around the dual tires, check to see that all lugs/wedges are in place and tight. Inspect wheel for any leakage that may be coming from inside the wheel housing that would indicate planetary leakage. Check pumps on the right front of transmission for leakage, and that all parts are secure. 21. Move in behind the right front wheel, and inspect the tie-rod and steering cylinder for proper greas- ing, and for security of all parts. Be sure the suspension protective cover is in good condition. Check suspension attaching hardware and sus- pension extension, as well as greasing and attach- ing hardware for the steering cylinder.

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. 22. Move out and around the right front wheel, inspect that all lugs/wedges are in place and tight. 13. Inspect left rear suspension for damage and for proper inflation, and that there are no leaks. Inspect also for proper greasing, and that the covers over the chromed piston rod are in good condition. 23.

Move in behind the front of the right front wheel, check hub and brakes for leaks and any unusual condition. Inspect the engine compartment for any leaks and unusual condition. Inspect the fan guard, and belts also for any rags or debris behind radiator. 14. Check final drive housing breather. Clean or re- place breather, if obstructed. Check for leakage around final drive housing and wet disc brake housings and the hoses connected to the hous- ings. 24. Move on around to the right front of the truck.
