Replace Steel Track
1. Thoroughly wash entire chassis and all components.
Note: Steel track assemblies weigh 340 kg (748 lb) each.
2. Position machine on a firm level surface near an over-
head lifting device. Ensure boom is in the lowered and
stowed position.
3. Rotate turntable as needed for unrestricted access to
side of chassis having track replaced.

RELEASED. GREASE IS UNDER PRESSURE. FITTING COULD FLY OFF AND CAUSE
INJURY.
