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 an uneven cut.
Check the pressure at the valve stem after every
50 operating hours or monthly, whichever occurs first
(Fig. 39). 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 50 operating hours
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important
Use the specified oil or equivalent. Other
fluids could cause system damage.
Hydraulic System Oil Capacity: 67 oz. (2.0 l)
Note: There are 2 ways of checking the hydraulic oil. One
is for warm oil and the other for cold oil. The baffle inside
the tank has 2 levels depending on whether the oil is warm
or cold.
1. Move the machine onto a level surface and set the
parking brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 40).

3. Remove the cap from the filler neck and look inside to
check if there is fluid in the reservoir (Fig. 40).
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 18.
6. Check the fluid level while the fluid is warm. The fluid
m–1872
should be between the Cold and Hot levels.
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. 40).
8. Install cap on filler neck.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
If hydraulic fluid is injected into the skin, it
must be surgically removed within a few hours
by a doctor familiar with this type of injury;
otherwise, gangrene may result.
Keep your body and hands away from pin hole
leaks or nozzles that eject high-pressure
hydraulic fluid.
Use cardboard or paper to find hydraulic leaks.
Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
Ensure that all hydraulic fluid hoses and lines
are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
