d. Raise the seat forward to expose the hydraulic oil
fill point.
e. Clean the area around the hydraulic fill oil cap.
f. Remove hydraulic fill oil cap.
g. Place a suitable container (at least 1 gallon) under
the hydraulic reservoir and filter.
h. Remove the hydraulic filter to allow hydraulic oil
to drain. Remove the drain plug from the bottom
of the hydraulic oil tank to drain. Replace the
plug.
i. Place a small pan under the pump motor frame.
Remove fill oil cap from hydraulic reservoir for
faster drainage. Remove nut caps and drain oil
from both left and right pumps. Replace and
retighten nuts.
j. Remove the three screws from the top of the oil
filter and 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.
k. Add proper amount of hydraulic oil to reservoir.
Use Shell Rimula 15W40 or equivalent with 1.5
ounces of Ornite additive.
l. Run and purge gearboxes. Check oil level.
m. Add proper amount of hydraulic oil to reservoir
and repeat step L.
C.Electrical Circuit
Danger:
Read General Safety Precautions Nos. 9 and 10.
1. Battery: The battery is located beneath the opera-
tor’s seat. Remove the fillcaps and check the level of
the liquid electrolyte in the battery every 50 operat-
ing hours. If the level in any of the six cells has
dropped below the bottom of the split ring inside the
fill hole, refill the cell with distilled water. To keep
the outside of the battery clean, brush on a strong
solution of bicarbonate of soda and water and rinse
with clean water. Keep the contacts and cable ends
clean with a wire brush and make sure the connec-
tions are tight. Coat the terminals with petroleum
jelly to prevent corrosion.
2. Battery Storage: When storing the Mower for long
periods of time the following guidelines should be
taken.
a. Disconnect the battery cables from the terminals
and remove the battery. You will have to remove
the control panel to access the battery strap.
Replace control panel.
b. Clean the battery before storing. A dirty battery
will lose its charge over time.
c. Store the battery with a full charge. A discharged
battery will freeze (refer to the table below)
d. Recharge battery when ever the specific gravity
value is less than 1.225
3. Battery Removal
Warning:
When removing the cables from the battery follow
these steps to avoid a short between the wrench and
the frame.
a. Remove the Negative (black) cable.
b. Remove the Positive (red) cable.
c. Release the hold down straps.
d. Remove the battery without tipping.
4. Installing the Battery
Note:
The battery is delivered from the factory
fully charged and filled with electrolyte.
a. Attach the Positive (red) cable.
b. Attach the Negative (black) cable.
c. Attach the rubber battery strap.
5. Jump Starting
Warning:
Note:
For E.F.I. Tanks, the battery must be discon-
nected (Negative lead) for storage exceeding four
weeks. Do not “Jump Start” an E.F.I. unit, recharge
or replace battery to avoid damage to the Electronic
Control Unit (ECU).
Failure to use this starting procedure can cause
sparking, and the gases in the battery to explode.
