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.
Hydraulic
pumps

Unfasten hose and drain from this side of both pumps.
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)
Specific Gravity | Freezing Temp (°F) |
|
|
1.265 | |
|
|
1.250 | |
|
|
1.200 | |
|
|
1.150 | 5 |
|
|
1.100 | 16 |
|
|
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.
