• Traction Forward and Reverse (Figure 46) (behind
the wheel motors) has a normal relief setting of
approximately 5300 psi and 50 to 150 psi charge
pressure. Use a gauge with 7500 to 10,000 psi full
scale rating.
• Cutting unit Counterbalance has adjustable pressure:
Normal Setting
Maximum Hill Climbing Setting
Maximum Quality of Cut
Setting
Lift circuit relief pressure is approximately 2650 psi when
counterbalance setting is 550 psi.
Note: Changes in counterbalance setting will effect
the lift circuit relief pressure.
• Cutting Unit Circuit has a normal relief setting of
approximately 2700–3000 psi.
• Steering Circuit has a normal relief setting of
approximately 1500 psi.
• Lift/relief Circuit has a normal relief setting of
approximately 2650–2750 psi.
• Charge Pressure Circuit has a normal relief setting of
approximately 100–150 psi.

Preparing the Traction Unit

1. Thoroughly clean the traction unit, cutting units,
and engine.
2. Check the tire pressure.
3. Check all fasteners for looseness and tighten them
as necessary.
4. Grease all grease fittings and pivot points. Wipe up
any excess lubricant.
5. Lightly sand and use touch-up paint on painted areas
that are scratched, chipped, or rusted. Repair any
dents in the metal body.
6. Service the battery and cables as follows:
A. Remove the battery terminals from the battery
posts.
B. Clean the battery, terminals, and posts with a
wire brush and baking soda solution.
C. Coat the cable terminals and battery posts with
Grafo 112X skin-over grease (Toro Part No.
505-47) or petroleum jelly to prevent corrosion.
D. Slowly recharge the battery every 60 days for 24
hours to prevent lead sulfation of the battery.

Preparing the Engine

1. Drain the engine oil from the oil pan and replace
the drain plug.
2. Remove and discard the oil filter. Install a new oil
filter.
3. Refill the oil pan with designated quantity of motor
oil.
4. Start the engine and run it at idle speed for
approximately two minutes.
5. Stop the engine.
6. Thoroughly drain all fuel from the fuel tank, lines,
and the fuel filter/water separator assembly.
7. Flush the fuel tank with fresh, clean diesel fuel.
8. Secure all fuel system fittings.
9. Thoroughly clean and service the air cleaner
assembly.
10. Seal the air cleaner inlet and the exhaust outlet with
weatherproof tape.
11. Check the antifreeze protection and add as needed
for expected minimum temperature in your area.
