Komatsu — QUICK FILL SERVICE CENTER

OM4041 08/11 Lubrication and Service - Section 40 Page 40-1 LUBRICATION AND SERVICE Preventive maintenance contributes to the long life and dependability of the truck and its components. The use of proper lubricants and the performance of checks and adjustments at recommended intervals are crucial. Unacceptable Practices Use of high-silicate anti-freeze. Under concentration or over concentration of Extended Service Additive (SCA). Lubrication requirements reference the lube key found in the lubrication chart. For detailed service requirements for specific components, refer to the shop manual. Use of anti-freezes/coolants that are not fully formulated for extended service intervals.

Use of sealing additives (stop-leak) in the cooling system. The service intervals presented here are in hours of operation. Oil change intervals are recommended in the absence of an oil analysis program which may determine different intervals. However, if the truck is being operated in extreme conditions, some or all of the intervals may need to be performed more fre- quently. Use of soluble oils in the cooling system. Use of poor-quality water. See the engine manufacturer’s specifications for water quality requirements. Use of anti-freeze, Extended Service Additive (SCA) or coolant filter(s) that do not meet the engine manufacturer’s specifications.

Refer to the engine service manual when servicing the engine or any of its components. Use of Treated Water coolant. Use of coolants with less than 40 percent antifreeze. QUICK FILL SERVICE CENTER The service center (Figure 40-1) is located on the left side of the truck below the hydraulic tank. The ser- vice center can be used to fill system fluids at a higher rate of speed than manually adding fluids and grease. Connect a filling device to the appropriate fitting on the service center to add fluids/grease. Use caution when adding fluids to avoid overfilling. COOLANT SPECIFICATIONS For ambient temperatures of -25° F (-32° C) and above, use a standard 50/50 anti-freeze-to-water mixture.

For arctic climates with ambient temperatures between -25° F (-32° C) and -65° F (-54° C), use a 60/40 anti-freeze-to-water mixture. NOTE: Do not use propylene glycol coolant in arctic climates. Only use ethylene glycol coolants. FIGURE 40-1.
