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: 67 oz. (2.0 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 the machine on a level surface and set the
parking brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 50).
3. Remove the cap from the filler neck. Look inside to
check if there is fluid in the reservoir (Fig. 50).
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 19.
6. Recheck 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. 50).
8. Install cap on filler neck.

Warning
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.
Gangrene may result if this is not done.
Keep 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.
Make sure all hydraulic fluid hoses and lines
are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
