WARNING
!
To avoid serious injury or death:
•
Shut power machine down and release all hydraulic
pressure to the equipment before connecting or
disconnecting hydraulic hoses to or from the power
•
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.
The double-acting wing cylinders (#1) should be attached
to a duplex outlet at the tractor with float capabilities to
allow the wings to float over the contour of the ground
while harrowing. The double-acting hydraulic lift cylinder
(#2) should be attached to a duplex outlet at the tractor
set for non-floating.
1.
Clean all dirt from tractor duplex outlets and all
hydraulic hose quick disconnect couplers (#8).
2. Make certain wing cylinder hydraulic hoses (#10) are
routed through hose loops (#19, #20 & #21).
3. If tractor has float option on one of the duplex outlets,
connect hydraulic hoses (#10) to that outlet and set
duplex outlet in float position.
4. Make certain lift cylinder hydraulic hoses (#11) are
routed through hose loops (#19, #20 & #21).
5. Attach lift cylinder hydraulic hoses (#11) to a duplex
outlet of the operator’s choosing. If duplex outlet has
float option, set outlet to non-float.
