MAINTENANCE OF TRACKED UNDERCARRIAGE
RUBBER TRACK TENSION
When the tracked undercarriage is lifted the rubber track must sag 10-15 mm.
When tension decreases it must be re-tightened to prevent the track from coming off.
Do not over tighten. If you continue to pump grease into the cylinder once the track is already
tight, you will compress the cylinder spring and cause excessive damage.
CORRECT INSPECTION AND MAINTENANCE PROCEDURES.
Always perform maintenance on a solid and level surface.
Never grease or lubricate or perform maintenance on the machine while it is in motion.
Solidly support the undercarriage if it needs to be lifted up for maintenance.
Use great care when maintaining the hydraulic system since oil is very hot when the machine
has just finished working.
Circuits are under high pressures even when the machine is not working.
Keep all components properly installed and in good condition.
Immediately repair all damage and replace worn or broken parts.
Remove any build-ups of grease, oil or debris.
Check for oil leaks and /or damaged hydraulic hoses.
Use recommended lubricants. Do not mix different brands of lubricants.
Use only original spare parts.
Keep undercarriage widening cylinder and track-stretcher grease nipples clean.
Intervals for periodic maintenance are indicated for normal work conditions. If the tracked
undercarriage is used in severe work conditions then maintenance must be performed at
shorter intervals.
Dispose of lubricants in an ecologically safe way. Thoughtless disposal of lubricants can
damage the environment. Become familiar with local anti-pollution laws and regulations before
disposing of lubricants.
Use suitable containers when draining lubricants. Do not use beverage or food containers that
might tempt someone to drink from them. Never pour lubricants on the ground or in a canal,
pond or watercourse. Comply with current environmental protection regulations when
disposing of lubricants.
GEAR OIL
Avoid using oils with different characteristics and brands
CHOICE OF TYPE OF REDUCTION UNIT OIL
We recommend, for reduction units, using gear oils with E.P. additives and viscosity class
according to ISO VG 150 or SAE 80W/90.
When temperature variation ranges are very high we recommend using synthetic oils with E.P.
properties and minimum 165 viscosity index and viscosity class VG
