5.3 MAINTENANCE TASKS
Maintenance tasks are described in the following sections.
5.3.1 AFU
Clutch performance may be compromised if the machine has been “crashed,” has
seen over a thousand hours of operation, or is operated in a dirty environment.
If the axial feed fails, check that the shear pins are intact. Extra pins are included
with the assembly. The pins must be in place (notched end out) to engage the feed.
Freezing temperatures may cause the axial feed box to run sluggishly.
5.3.2 Boring bar
Check the bar regularly for nicks, cuts, or abrasions. Dress the bar smooth if neces-
sary. A bar with nicks or gouges can damage the bearing supports and RDU
beyond repair. Wipe the bar clean with solvent to remove dirt and chips.
5.3.3 Hydraulic power system
For information on maintaining the hydraulic power system, see the manufac-
turer’s documentation for your hydraulic system.
