Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
Only trained personnel should work on system hydraulics!
Protecting Hydraulic Motor Seals
Low Pressure (Case) Drain Connection
Motor Seal Damage Risk:
Case Drain Hose must be attached prior to inlet and return
hoses being connected. Also, it must be unhooked last to
prevent damage to the fan motor.
1. Attach case drain hose to low pressure drain
connection.
Note: Case drain hose must be hooked up first. Also, it
must be unhooked last to prevent damage to
hydraulic motor seals.
2. Connect low pressure return hose to low pressure
return connector.
Hydraulic Motor Performance Risk:
DO NOT hook case drain line to a “power-beyond port”.
3. If the tractor has a limited number of remotes
capable of continuous flow, use one for the fan. (See
“Specifications and Capacities” on page 97 for
tractor requirements.)
