5.12 HYDRAULIC HOSES _______________________________________________________
!
WARNING
To prevent serious injury from hot, high pressure oil
never use your hands to check for oil leaks; use paper
or cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected into
the skin it must be surgically removed within a few
hours by a doctor familiar with this form of injury or
gangrene may result.
1. Always disengage all drives, engage parking brake,
stop engine, and remove key before inspecting or
disconnecting hydraulic lines or hoses.
2. Check visible hoses and tubes daily. Look for wet
hoses or oil spots. Replace worn or damaged hoses
and tubes before operating the machine.
3. The replacement tube or hoses must be routed in
the same path as the existing hose. Do not move
clamps, brackets, and ties to a new location.
4. Thoroughly inspect
connections every 250 hours.
5.13 HYDRAULIC RESERVOIR AND FILTER ________________________________________
Refer to Section 7.3 for specific maintenance intervals.
Normally the hydraulic system will not need additional
fluid. Sometimes a leak may develop causing the system
to require repair and refilling. If you notice hydraulic fluid
escaping when the system is being used or if a leak is
suspected turn off all hydraulic functions and stop
the engine.
Periodically check the hydraulic fluid level (hydraulic level
should be checked every 100 hours of operation). Loss
of fluid can signal a small leak before it becomes worse.
To check the fluid level:
1. Place vehicle on a flat and level surface. Fully lower
any accessory attachment, including the dump box.
Stop the vehicle engine.
2. Remove the dipstick/breather tube from the top of
the tank. Wipe the dipstick then place in tank with
the threaded flange resting on the tank (do not
screw in). Fluid should show on the knurled portion
of the dipstick. Add GreensCare 68™ fluid as
required.
The hydraulic system is protected by one 10 micron filter.
The filter is located under the side console near the
parking brake lever.

MAINTENANCE
IMPORTANT: The hydraulic system can be
permanently damaged
contaminated. Before disconnecting any hydraulic
component clean the area around the fittings and the
hose ends to keep impurities out of the system.
a. Before disconnecting any hydraulic component
tag or mark the location of each hose then clean
the area around the fittings.
b. As you disconnect the component be prepared to
assemble plugs or caps to the hose ends and
open ports. This will keep impurities out of the
hydraulic system and also prevent oil spills.
c. Make sure O-rings are clean and hose fittings
are properly seated before tightening.
d. Keep the hose from twisting. Twisted hoses can
cause couplers to loosen as the hose flexes
during operation resulting in oil leaks.
e. Kinked or twisted hoses can restrict the oil flow
causing the system to malfunction, the oil to
overheat and also lead to hose failure.
To replace hydraulic oil filter:
1. Remove the old filter.
2. Fill new filter with GreensCare 68 fluid then install
new filter. Hand tighten only.
3. Operate engine at idle speed with hydraulic system
in Neutral for five minutes.
4. Check hydraulic oil level and fill with GreensCare 68
to knurled mark on gauge.
