WARNING
!
To avoid serious injury or death:
Hydraulic fluid under high pressure will penetrate the skin or
eyes causing a serious injury. Wear protective gloves and
safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than hands
when searching for leaks. If an accident occurs, seek
immediate emergency medical care or gangrene may result.
Hydraulic hoses and cylinders are supplied fully charged
with oil from the factory and should not require bleeding.
If any of the decks raise or lower in a jerking motion, then
bleed the hydraulics as follows:
1. With mower decks lowered onto the ground, remove
connecting pins (#1) from rod end of the 2 wing
cylinders (#2) and center deck cylinder (#3).
2. Support cylinders in a vertical position with rod end
up.
3. Cycle hydraulic system to extend both wing cylinders
and center deck cylinder. Retract cylinders and
repeat this process 2 times.
4. On each cylinder, crack rod end cylinder fitting (#4)
and apply hydraulic pressure until air free oil leaks
from fitting and tighten fitting.
5. Support cylinders in a vertical position with base end
of cylinder up and repeat bleeding process on the
base end fitting (#5).
6. Re-pin all clevises. Secure connecting pins with
cotter pins (#6) by bending one or more legs of cotter
pin.
7. Slowly cycle all decks to transport position checking
to make sure the hydraulic hoses are not pinched in
the process.
