Table 4-1.Maintenance Frequency Table

Light to Moderate

Perform all of the scheduled inspections and maintenance during the suggested intervals. The time intervals given in this guide are based on Deadman Hours (HD) under normal operating conditions.

When operating under Severe or Extreme conditions, perform these services more often as indicated in Table4-1 .

Refer to the “Lubrication Equivalency Chart” on pageA-2 in the Appendix for lubrication equivalents. Refer to the manufacturer’s supplements for components not identified in this manual.

An eight hour shift of basic material handlingFirst inspection at 90 days or 250 hours and then every 180 days or 500 hours, whichever comes first

Severe•Extended heavy duty operation

•Freezer operation

•Sudden temperature changes such as going from freezer to room temperature

Extreme•All UL Type EE rated lift trucks

•Dusty or sandy conditions such as in cement plants, lumber or flour mills, coal dust or stone-crushing areas

•High temperature areas such as in steel mills, foundries, enclosed (TypeEE) applications

•Corrosive chemical atmosphere such as in chlorine or salt-sea air environments

•Adverse high humidity, wet, damp, or moist conditions

60 days or 250 hours, whichever comes first

Initial 90 Day/250 Deadman Hour (HD) Maintenance

Perform the following maintenance tasks 90 days or 250 HD after the truck was put into service, whichever comes first.

Component Task

Drive UnitChange fluid. See “Lubrication Equivalency Chart” on pageA-2. Clean magnet on drain plug. See “Drive Unit Housing Lubrication” on page7-27.

Hydraulic ReservoirChange hydraulic fluid. See “Lubrication Equivalency Chart” on pageA-2 Clean filter screen and magnet. See “Filter Screen” on page7-77

Electrical CablesInspect all cables for nicks or cuts (including battery pack and charger cables). Give special attention to those cables that are not stationary, for example, cables to the traction motor. Replace any cable that is damaged or shows signs of excessive heat. Failure to do so may cause intermittent system shutdowns and/or electronic failures.

Arm Angle SwitchCheck the adjustment. See “Arm Angle Proximity Switch Adjustment” on page7-57.

Traction AmplifierCheck bolt torque of all mounting and terminal hardware.
