6. Belt tension adjustment
First loosen the 4 screws (Y) which secure the pulley
housing then loosen jam nut (T). Tighten belts using bolt
(Z) until tension is sufficient to prevent belts from slipping
during operation.
Do not overtighten belts as they also act as a safety device
and should slip in case the machine becomes blocked.
After adjustment, retighten all bolts (Y) and jam nut (T).
7. Forward speed
Operate with a forward speed of 6.4 km/hr (4 mph) and a PTO speed of 540 rpm. This allows 9-10 revolutions of the final
drive pulley for every 3 ft of travel. Maintain the PTO speed and adjust tractor speed by gear selection, not by acceleration.
TRANSPORT & PARKING POSITION
To change the machine from the working position to the
transport position, proceed as follows :
- Fit the finger guard (T) in place and secure with 2 screw
springs (R).
- Pull cord (X) to free stop (C).
- Manually raise the cutterbar (P) until it is automatically
secured by latch (G).
- Secure cutterbar in the vertical position by fitting
linchpin (D) in transport hole (F).
