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 stability. Secure blocking prevents equipment from drop- ping due to hydraulic leak down, hydraulic system failure, or mechanical component failure.

„Keep all persons away from operator control area while performing adjustments, service, or maintenance.

CAUTION

„Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.
