IMPORTANT:
Foreign material such as dirt, dust, and water is the major cause of trouble in the hydraulic system.
If hydraulic system components must be disconnected for service, protect the ends of hoses, tubing, and
ports of components from contamination with clean, lint-free towels, or clean plastic bags.
Before installing any replacement hose, fl ush the inside with unused diesel fuel or unused commercial
petroleum cleaning solvent for ten seconds minimum. Do
NOT
use water, water soluble cleaners, or
compressed air.
The hydraulic system components are built to very close tolerances and have been adjusted at the factory.
Do
NOT
attempt to service these components except to maintain proper oil level, change oil and fi lters, and
to adjust relief pressures as described in this manual.
See your MacDon Dealer for all other service.
