Refer to Figure 1-20:
WARNING
!
To prevent serious injury or death:
•
Stop the tractor and release the pressure from the hydraulic
system before starting any work on the hydraulic system.
•
Hydraulic fluid under high pressure can penetrate the skin
and/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. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.

Blue Caps (#1): Hoses for lateral adjustment.
•
Red Caps (#2): Hoses for incline adjustment.
2. Connect the quick release couplings with blue
caps (#1) to the duplex outlet on the tractor
designated for operating the lateral adjustment.
3. Connect the quick release couplings with red
caps (#2) to the duplex outlet on the tractor
designated for operating the incline adjustment.
