OM4016 08/07 Maintenance - Section 4 Lubrication and Service Page 4-1 LUBRICATION AND SERVICE Preventive Maintenance will contribute to the long life and dependability of the Komatsu truck and its com- ponents. The use of proper lubricants and the perfor- mance of checks and adjustments at recommended intervals is most important. The service intervals presented here are in hours of operation. These intervals are recommended in lieu of an oil analysis program which may deter- mine different intervals. However, if the truck is being operated under extreme conditions, some, or all, of the intervals may need to be shortened and the service performed more frequently.
Lubrication requirements are referenced to the lube key found at the top of the Lubrication Specifications Chart (next page). Refer to engine manual when servicing the engine or any of its components. For detailed service requirements for specific compo- nents, refer to the shop manual section for that com- ponent (i.e. Section "G" for Final Drive, Section "H" for Suspensions, etc.). Refer to Transmission Oil Level Check, page 4-7. COOLING SYSTEM ANTI-FREEZE RECOMMENDATIONS (Ethylene Glycol Permanent Type Anti-Freeze) Percentage of Anti-Freeze Protection To:
