Functional Check
1.
Remove the deck safety chain from the latch position
and place the loose end on the stowage hook
provided. See Figure 2-9. Start the tractor and adjust
the 3-point hitch until the PTO shaft is approximately
level.
2.
Cycle the parallel arm and deck cylinders for proper
operation.
!
DANGER
Hydraulic fluid under pressure can penetrate skin. 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 hydraulic leaks. If
hydraulic fluid is injected into the skin, it must be treated by a
doctor within a few hours or gangrene may result.
a. In Step 1.a. (Hydraulic Hookup), two hoses from
the Solenoid Control Valve were connected to a
single duplex outlet on the tractor. If the tractor is
equipped with more than one remote duplex
outlet, you must first determine which console
lever is used to control this outlet. The control
lever must then be locked into the “Automatic
Extend Position” or the “Automatic Retract
Position”.
NOTE: The following procedure assumes that the
cutter is equipped with the optional Electric Cylinder
Control. Go to step “c” if your cutter is not equipped
with this option.
b. Toggle the switch on the control box labeled
“ARM1” by pushing it forward (away from you).
The inboard parallel arm should extend outward.
If it does not move, or moves in the opposite
direction (retracts), you should either change the
position of the console lever (from retract to
extend or vice-versa) or reverse the hoses at the
duplex outlet. Toggle the ARM1 switch by pulling
back on it. The inboard parallel arm should
retract. See Figure 2-10.
Repeat this procedure for the remaining arm and
deck cylinders. Cycle all of the cylinders to full
extension and retraction to remove any air that
might be trapped in the system.
Check the hydraulic fluid level in your tractor's
reservoir. If low, add fluid to the system before
proceeding. The cylinders and hoses will require
approximately 1 3/4 gallons from the tractor.
c. Operate the tractor console control lever
designated for “ARM1” by pushing it forward. The
inboard arm should extend outward. If the arm
tries to retract, reverse the hoses at the duplex
outlet. See Figure 2-10.
Repeat this procedure for the remaining arm and
deck cylinders. Cycle all of the cylinders to full
extension and retraction to purge any air that
might be trapped in the system.
NOTE: The following procedure is for those cutters
that are not equipped with the Electric Cylinder
Control.
