Hydraulic Oil Tank and Filter
NOTE:
Used hydraulic oil must be disposed of properly. Do
not pour it down a drain or sewer, or dump it on open land,
this creates an environmental hazard. Please be aware of the
environment when disposing of used oil.
Place the tractor on a level surface and engage the parking
1.
brake.
Stop the engine and remove the key from the ignition
2.
switch.
Raise the seat forward to expose the hydraulic oil fill point.
3.
Clean the area around the hydraulic fill oil cap.
4.
Remove hydraulic fill oil cap.
5.
Place a suitable container (at least 2 gallon) under the
6.
hydraulic reservoir and filter.
Remove the two bolts securing the hydraulic filter and
7.
allow the hydraulic oil to drain. Remove the drain plug from
the bottom of the hydraulic oil tank to drain. Replace the
plug. See Fig. 6-3.
Place a small pan under the pump motor frame. Remove fill
8.
oil cap from hydraulic reservoir for faster drainage. Remove
nut caps and drain oil from both left and right pumps.
Replace and retighten nuts. See Fig. 6-3.
Remove the three screws from the top of the oil filter and
9.
replace the oil filter element. Coat the sealing surface
with Shell Rimula 15W40 oil or equivalent. Install the three
screws back into the oil filter.
Add proper amount of hydraulic oil to reservoir and 1.5
10.
ounces of Ornite additive.
Run and purge pumps and motors. Check oil level.
11.
Add proper amount of hydraulic oil to reservoir and repeat
12.
step 11.
NOTE:
This unit is equipped with two traction drive pumps
and one pump for steering and implement lift.
NOTE:
After unit is up to operating temperature, turn off
engine and re-check hydraulic oil. If oil appears foamy or
contains excessive air bubbles, DO nOT OPERATE UnIT.
Contact service technician.
Contaminants or foreign matter in the oil will also damage the
pumps . To prevent this:
Use a filter that captures particles as small as 25 microns or
•
25 millionths of a meter in diameter.
Be very careful when you remove or repair a component in
•
the hydraulic system. Thoroughly clean off any component
before you work on it.
Plug the ends of any hose or line you remove with a rubber
•
or plastic plug.
Use plastic caps to seal off the ends of hydraulic fittings.
•
Place any component you remove in a clean plastic bag so
•
it can’t pick up dust or dirt.
Clean your hands frequently when working on the
•
hydraulic components.
NOTE:
The pumps are not owner-repairable. If a pump fails,
contact your Service Center. Do not disassemble the pump.
Hydraulic System
Hoses
Check the hoses from the hydraulic oil tank to the oil filter to
the hydraulic lines daily for leaks or abrasion and replace any
damaged hoses. Make certain there are no kinks or twists in any
hose. Look for a flattened condition or any leaks and repair or
replace as necessary. A flattened or leaking suction hose will
permit cavitation to develop which can destroy the pumps in a
short time.
General Battery Information
WARNING!
Should battery acid accidentally splatter into
•
the eyes or onto the skin, rinse the affected area
immediately with clean cold water. If there is any
further discomfort, seek prompt medical attention.
If acid spills on clothing, first dilute it with
•
clean water, then neutralize with a solution of
ammonia/water or baking soda/water.
NEVER connect (or disconnect) battery
•
charger clips to the battery while the charger is
turned on, as it can cause sparks.
Keep all sources of ignition (cigarettes,
•
matches, lighters) away from the battery. The gas
generated during charging can be combustible.
As a further precaution, only charge the
•
battery in a well ventilated area.
Always shield eyes and protect skin and
•
clothing when working near batteries.
Batteries contain sulfuric acid and may
•
emit explosive gases. Use extreme caution when
handling batteries. Keep batteries out of the reach
of children.
