SERVICE POINTS

WARNING
The PTT unit should be fully tilt up posi-
tioned (all the tilt rod should be fully
lengthen) for disassembly to cancel the
internal pressure and prevent the hydrau-
lic fluid from spurting out.
After removing the tilt motor or oil reser-
voir, do not push down the tilt rod. It may
cause hydraulic fluid to spurt out from
the port.
CAUTION:
Do not wipe components of the hydraulic
system with rags, paper, tissues, or the like
as fibers from such material will cause mal-
function if they enter the system.
NOTE:
Tilt cylinder removal is not required for the
cylinder repair.
