3.6 IN WORK
- Choose between tractor lifter "Position Control" or "Stress
control";
- Open valve faucet (fig.10).
- Lift up and unfold completely the machine;
- Lock tractor spool valve (only wings!) to prevent unintentional
unfolding;
- Lower the implement acting on tractor lifter and spool valve
(carriage);
ATTENTION
The implement working speed should be mantained betwe-
en 8 and 15 km/h to ensure a well-made field cultivation.
3.7 WORKING IN STRESS-CONTROL POSITION
- Check the FWD traction is switched on; (pic.15)
- Set lifter fall speed near the highest value; (pic.16)
- Set lifter moving speed near medium value; (pic.17)
- Identify lifter stress value that gives soil-implement right posi-
tion - parallellism (pic.18)
In this way lifter stress control action will act by lifting implement
(when pulling power requirement or slippage are too high) and
consequently optimizes traction.
If implement working arrangement needs to be modified, act ca-
refully on stress control potentiometer to avoid too large changes.
ATTENTION
The implement must only be used, mantained or repaired by
such people who have the right knowledge about it and who
have been advised about the various dangers.
Adjustement and maintenance operations must be carried
through with tractor engine stopped and implement in secure
and stable position.
