HOURMETER - CHECK FOR MAINTENANCE INTERVAL
The hourmeter on the machine is used to determine maintenance intervals for the machine. The hourmeter
indicates the total number of hours the engine has been in operation.
Maintenance intervals are based on normal operating conditions. When operating under severe conditions, the
maintenance intervals should be shortened.
MACHINE - GREASE
As a general rule, grease machine after it is shut down for the day or at 5 service hours if required. This protects
metal under seals from corrosion caused by condensation as temperature drops.
Ensure all fittings and nozzle of grease applicator are clean before applying grease. If any grease fittings are
missing, replace them immediately.
RECOMMENDED FLUIDS
Refer to the Specifications section in the Maintenance Manual for fluid and lubricant requirements.
