MACHINE - GREASE
As a general rule, grease machine after it is shut down for the day. This protects the metal under the seals from
corrosion caused by condensation as the temperature drops.
Ensure all fittings and grease applicator nozzle are clean before applying grease. If any grease fittings are
missing, replace them immediately.
ENGINE MAINTENANCE
•Checkfluidlevels.
•Checkaircleanerindicator.
• Perform walk-around inspection.
Refer to the Engine Operation Manual supplied with the machine for engine maintenance information.
FLUID LEVELS - CHECK
Check fluid levels daily before operating the machine. Also, inspect machine and
make any necessary adjustments and repairs before starting the engine. Refer to the
Engine Operation Manual.
Engine Oil Level - Check
With engine level, fill to full mark on dipstick. Do not overfill.
