TRACK BASE MAINTENANCE
Safe Maintenance
• Solidly support the under carriage if it needs to be
lifted up for maintenance (see Chassis Jacking
Point section on page 20).
• Hydraulic systems may get very hot after working.
• Keep all components in good condition as they
are exposed to high pressures.
• Immediately repair damage and replace worn or
broken items.
Maintenance intervals are only guidelines. The amount of times maintenance is conducted should be increased beyond
recommended guidelines if severe conditions are encountered.
LUBRICATE VARIABLE TRACK BASE SLIDES
The variable track base slides must be lubricated weekly or more often
depending working conditions to prevent jamming.
1 Extend tracks fully.
2 Using a brush, generously coat all surfaces of the four slider bars with
general purpose grease. DO NOT USE GRAPHITE BASED GREASE.
3 Retract the tracks fully.
4 Cycle tracks in and out two more times.
