Hydraulic System
Checking the Hydraulic Fluid
Check the hydraulic fluid level:
• Before engine is first started.
• After first 8 operating hours.
• After 25 operating hours.
Fluid Type: Mobil 1 15W–50 synthetic motor oil.
IMPORTANT: Use only oil specified. Other
fluids could cause system damage.
System Capacity: 2.1 qt. (2.0 l)
1. Position machine on a level surface, stop the
engine and set the parking brake.
2. Clean area around filler neck of hydraulic tank
(Fig. 36).
3. Remove cap from filler neck. Look inside to
check if there is fluid in the reservoir. (Fig. 36).
4. If there is no fluid, add fluid to reservoir
approximately a 1/4(6mm) below the top of
baffle.
5. Run the machine 15 minutes to allow any air to
purge out of the system and warm fluid.
6. Recheck level while fluid is warm. Add fluid to
raise level to top of the baffle, if required.
Note: Fluid level should be to the top of the
baffle when fluid is warm (Fig. 36).
7. Install cap on filler neck.

POTENTIAL HAZARD
• Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
WHAT CAN HAPPEN
• Fluid accidentally injected into the skin
must be surgically removed within a few
hours by a doctor familiar with this form of
injury or gangrene may result.
HOW TO AV
OID THE HAZARD
• Make sur e all hydraulic fluid hoses and
lines ar e in good condition and all
hydraulic connections and fittings are tight
before applying pressure to hydraulic
system.
• 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.
