Fitting controls
The position of the lever unit inside the tractor cab depends largely upon the route of the cables between
unit and control valve.
The control valve is mounted on the front face of the oil tank.
The cable normally can be routed through the rear cab window and should be as free of bends as
possible. DO NOT PINCH CABLE IN CLOSED WINDOW.
NOTE : Avoid sharp bends. The rotor control cable must not have a bend of less than 150mm (6 in)
radius.
If the tractor cab has special apertures for cables the lever unit should be through them before they are
attached to the tractor cab.
Follow instructions below for fitting lever unit.
A. Pass lever unit and cable through suitable aperture in rear of tractor cab.
NOTE : It is essential not to drill mounting holes through any structural member of the safety cab.
B. Mount the unit securely on to the mounting bracket with bolts provided.
C. Finally, check levers for smooth operation in both directions. If any stiffness is felt or if levers do not
return to center, check cable route for sharp bends.
Hydraulic systems
It is to not necessary to connect to the tractor hydraulics. The second pump, mounted on the PTO -
driven gearbox, provides the hydraulic supply to the control valve for operation of the rams. A diverter valve
in the main rotor drive circuit, operated by remote cable control, allows the rotor unit to be stopped while
the PTO drive is in operation.
FILL TANK WITH OIL
NOTE
: Before filling tank with oil connect the Drive Hose together, using one of the adaptors from the
motor fitted to the cowl.
The correct procedure for filling the oil tank is as follows:
A. Remove breather cap and strainer assembly and place at side of tank.
B. Check unions on suction hose from tank to pumps for tightness and freedom from kinks and restrictions
C. Fill tank with 150 liters (40 gal) of oil.
D. Replace breather cap and strainer assembly.
E. Avoid contamination at all time, particularly when the breather cap and strainer assembly are removed.
Hose layout
It is important that hoses are fitted correctly. To ensure that there are no kinks, sharp bends and that
the hoses do not chafe against sharp edges, the following layout should be used as a guide.
Twists
Hoses should never be twisted or kinked. On most hoses there is a line which runs the full length of the
hose acting as a useful guide (see
FIGURE 3-8 ). If there is no guideline running along the hose follow
the fitting instructions below
