Where to Add Light Oil or Spray
Lubrication
Lubricate the machine in the following areas with spray
type lubricant or light oil. Lubricate every 160 hours.
Seat switch actuator
Brake handle pivot
Brake rod bushings
Motion control bronze bushings
Checking the Tire Pressure
Maintain the air pressure in the front and rear tires as
specified. Uneven tire pressure can cause uneven cut.
Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Fig. 54). Check the tires when they are cold to get the
most accurate pressure reading.
Pressure: 13 psi (90 kPa) drive wheels and caster wheels

Servicing the Hydraulic
System
Checking the Hydraulic Fluid
Check the hydraulic fluid level:
Before the engine is first started.
After the first 8 operating hours.
After every 25 operating hours.
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important
Use oil specified or equivalent. Other
fluids could cause system damage.
Hydraulic System Oil Capacity: 4 quarts (3.8 l)
Note: There are two ways of checking the hydraulic oil.
One is when the oil is warm and one is when the oil is
cold. The baffle inside the tank has two levels depending
if the oil is warm or cold.
1. Position machine on a level surface and set the parking
brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 55).
3. Remove the cap from the filler neck. Look inside to
check if there is fluid in the reservoir (Fig. 55).
4. If there is no fluid, add fluid to the reservoir until it
reaches the cold level of the baffle.
5. Run the machine at low idle for 15 minutes to allow
any air to purge out of the system and warm the fluid.
Refer to Starting and Stopping the Engine on page 21.
6. Check the fluid level while the fluid is warm. The
fluid should be between cold and hot.
7. If required, add fluid to the hydraulic tank.
Note: The fluid level should be to the top of the hot level
of the baffle, when the fluid is hot (Fig. 55).
8. Install cap on filler neck.
