primary drive. The drive system must be maintained at the
proper belt tension and pulley alignment to obtain the desired
performance and life. When maintaining the primary belt drive
system, follow this procedure:
1. If the machine is in the raised position, Install transport
locks on left and right side of the lift axles to avoid cyl -
inders settling during servicing.
(See"Transport Locks:
Locking & Stowing" on page 4-12)
