HYDRAULIC SAFETY
1. Hydraulic fluid is under high pressure. If you need
service on your hydraulic system, please see your
dealer.
Keep body and hands away from pin holes or nozzles
that eject fluid under high pressure. Use paper or
cardboard, not hands, to search for leaks.
Hydraulic fluid escaping under high pressure may
have sufficient force to penetrate your skin and cause
serious injury. If fluid is injected into your skin, a
physician familiar with this form of injury must re
move it surgically within a few hours or gangrene
may result.
2. Make sure all hydraulic fluid connections are tight
and all hoses and lines are in good condition before
applying pressure to the system.
ADJUSTMENTS
Neutral Adjustment
1. Set the machine up on jack stands so the drive
wheels are free to rotate. Block the caster wheels to
prevent an accident if the machine should acciden-
tally fall off the jack stands.
2. Run Position: Move the dump valve lever (on Left
Hand side of mower) behind the hook on the frame
to close hydraulic dump valves on the pump. (See
Figure 1)
Free Wheel Position: ull lever back and to the
left, then push forward to relieve pressure. (See
Figure 1)
Figure 1
3. Start the engine and check if one or both of the
drive wheels are turning.
4. Adjust each drive wheel separately by using the
turnbuckles located under the seat. Loosen the jam
nut on the turnbuckle. (See Figure 2)
5. If the drive wheel is rotating forward, adjust the
turnbuckle clockwise. If the drive wheel is rotating
rearward, adjust the turnbuckle counterclockwise.
