WARNING
• See General Warnings, Section 1, Page 1-2.
• Always wear eye protection and protective clothing when working on and around hydraulic systems.
• Remove jewelry and objects that might conduct electricity while working on power units.
• Hydraulic fluid poses a fire hazard and can cause burning or skin irritation if not properly handled.
• Hydraulic fluid under pressure can penetrate skin or eyes, causing serious injury or death. Fluid leaks
under pressure may not be visible. Use a piece of cardboard or wood to find leaks. Do not use your
bare hand. Wear safety goggles. If fluid enters skin or eyes, get immediate medical attention from
a physician familiar with this injury.
• Devices being operated by the hydraulic system should be immobilized so they cannot move and
cause injury while being inspected or repaired. Disconnect from electrical source.
• Prior to performing any maintenance make sure the equipment is turned off and that any stored
energy, for example pressure, is released. Also, extended equipment or cylinders should be lowered
and mechanically locked as required.
• The manufacturer is not responsible for misuse or misapplication of product. If you have any
questions about application, please contact a local dealer.
• Fluids should be contained and disposed of properly.
This section contains procedures for inspection, troubleshooting, removal, installation, maintenance, and regular
servicing of vehicles equipped with the hydraulic attachment system.
MODEL IDENTIFICATION
This vehicle uses a Monarch Hydraulics Inc. model M-3518 Pump Unit.
RELIEVING HYDRAULIC SYSTEM PRESSURE
To prevent serious injury or death, hydraulic pressure must be relieved before disconnecting or removing the pump,
hoses and valves. Pressure can also cause difficulty in connecting or disconnecting the auxiliary hydraulic quick
connect fittings. Use the following procedure to relieve hydraulic pressure in the system.
TO RELIEVE HYDRAULIC FLUID PRESSURE
1.
Remove attachment if installed.
See Attachment Interface on page 19-2.
2.
Lower attachment interface, fully extending the lift and tilt cylinders.
3.
Turn the key switch to the OFF position to shut off vehicle. Turn the key switch back to the ON position, but DO
NOT start the utility vehicle engine. Keep the joystick ON/OFF switch set to ON.
4.
Relieve pressure in the desired circuit:
4.1.
For the tilt circuit, slightly retract the tilt cylinder to relieve most of the built up pressure.
4.2.
For the lift circuit, activate the float feature to relieve pressure.
