D. Rotate the valve connection by the hexagonal nut provided, while holding the cable to stop it from
rotating until the lever is in the required position.
E. Re-tighten the two capscrews.
F. Re-tighten the locknut.
ADJUST LEVER PIVOT POSITION
The ration of lever movement to cable movement can be adjusted on the Lever units. The lever/cable
ratio is supplied at the highest ratio, but two lower rations can be selected, i.e. with less lever travel but
higher force required, as follows.
A. With the lever units off the tractor remove the 3 throughbolts and nuts.
B. Remove the gaiter from the body of a control unit FIGURE 3-5 (C).
C. Drive out the tension pin from the lever unit pivot FIGURE 3-5 (D).
D. Remove the circlip and pivot pin from the end of the cable and then remove the lever FIGURE 3-5
(E).
E. Remove the sleeve from the lever pivot and take out the nylon bushes from the original pivot position
and replace in the required position.
F. Replace the sleeve in the bushes and replace lever in the control unit in the reverse sequence to the
above.
H. Replace all the rubber boots and reassemble with the 3 throughbolts and nuts.
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. See FIGURE 3-6.
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 restric-
tions
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 re-
moved.
