Castor Pivot Bearing
Adjustment
Check after every 500 operating hours or at storage, which
ever comes first.
1. Stop the engine, set the parking brake, remove the key
and disconnect the spark plug wire(s) from the spark
plug(s).
2. Remove dust cap from castor and tighten lock nut
(Fig. 48).
3. Tighten until spring washers are flat and then back off
a 1/4 turn to properly set the pre–load on the bearings
(Fig. 48).
Important Make sure spring washers are installed
correctly as shown in figure 48.

Servicing the Hydraulic
System
Checking the Hydraulic Fluid
Check the hydraulic fluid level before engine is first
started.
Check the hydraulic fluid level after first 8 operating
hours.
Check the hydraulic fluid level 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)
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. 49).
3. Remove cap from filler neck. Look inside to check if
there is fluid in the reservoir. (Fig. 49).
4. If there is no fluid, add fluid to reservoir
approximately a 1/4 in. (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. 49).
7. 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.
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.
