Checking the Hydraulic Fluid
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.
Warning
The hydraulic system is designed to operate on SAE
10W–30 engine oil or, as a substitute, SAE 10W–40
engine oil. The reservoir is filled at the factory with
approximately 4.75l (160 oz.) of 10W–30 engine oil.
Check reservoir oil level before engine is first started and
daily thereafter.
1. Raise seat and remove belt guard. See Removing Belt
Guard on page 21.
2. Position machine on a level surface and stop the
engine.
3. Remove dipstick cap from filler neck (Fig. 35) and
wipe it with a clean rag. Insert dipstick cap onto filler
neck; then remove it and check level of oil.
4. If level is not within 1/2 inch from full mark on
dipstick, add SAE 10W–30 engine oil to raise level to
FULL mark. Do not overfill.
5. Install dipstick filler cap onto filler neck (Fig. 35).
6. Run engine for approximately 1 minute, recheck
reservoir oil level and add as required.
7. Reinstall belt guard. See Installing Belt Guard on page
21.

Changing the Hydraulic Oil
The hydraulic system oil must be changed after every 250
hours of operation or yearly, whichever comes first. The
reservoir has a capacity of approximately 4.75l (160 oz.).
1. Park machine on a level surface, lower cutting unit,
engage parking brake. and shut engine off.
2. Clean the area around the hydraulic oil filter and
remove the filter from the bottom of the filter housing.
use bottom type filter wrench (Fig. 36).
3. Disconnect tube assembly and hose assembly from
reservoir and allow the oil to flow into a drain pan
(Fig. 36).
Note: To drain oil remaining in system, disconnect spark
plug wires and crank engine for 15 seconds. This will
pump remaining oil out of system thru tube assembly. Do
not crank engine for more than 15 seconds.
4. Install the new hydraulic filter onto bottom of the filter
housing (Fig. 36).
