DEALER SERVICE
The information in this section is written for dealer ser-
vice personnel. The repair described here requires
special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in
this type of repair, you may be time and money ahead
to replace complete assemblies.
■ Before working underneath, read manual
instructions, securely block up, and check sta-
bility. Secure blocking prevents equipment from
dropping due to hydraulic leak down, hydrau-
lic system failure, or mechanical component
failure.
■ Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
■ Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing,
and head; and respirator or filter mask where
appropriate.
