2500 Hayliner
17
2. Hydraulic System
WARNING Escaping fluid under pressure can have sufficient force to
penetrate the skin, causing serious personal injury. Before repairing, adjusting, or
disconnecting lines, be sure to relieve all pressure.
WARNING Never operate the 2500 Hayliner with frayed or damaged
hoses or leaking fittings. A burst would cause the lift arm to drop suddenly and result in
serious injury or death and cause damage to the loader or tractor.
Before applying pressure to the system, be sure all
connections are tight and the lines, pipes, and hoses are
not damaged.
Wear proper hand and eye protection when searching for
leaks. Use a piece of wood or cardboard instead of hand
to check for leaks.
Maintain all components in good working order.
If injured by escaping fluid, see a doctor at once. Serious
infection or toxic reaction can develop if proper medical
treatment is not administered immediately.
Regularly check the fluid level in the tractor reservoir and
follow the maintenance procedures in the tractor
Operator’s Manual.
Regularly inspect cylinders, hoses and fittings for leaks,
crimps and abrasions or other signs of wear and tear or
impending failure.
Ensure hoses do not bind or stretch during operation.
Always keep hoses tied or supported to prevent rubbing against sharp areas or
being pinched. We suggest using tie wraps to support hoses.
Replacement hoses must have a working pressure of 3000 psi (20685 kpa) or
higher.
