ADJUSTING THE REAR ROLLER.
As mentioned in 5.1, the rear roller 22 (Fig 5.) should be close to the ground to prevent
scalping of the turf when the machine is used as a scarifier or sweeper.
To adjust the rear roller, work as follows see fig.6.:
•
Be sure the engine is shut off
•
The head should be raised and secured with D- shackle 13 (see fig.5.)
•
Don’t creep under the machine.
•
Be sure the machine is blocked.
Adjusting the rear roller goes as follows, see fig 6.:
1.
Slacken nut 12.
2.
Move the roller up or down by hand.
3.
When the desired position is achieved, tighten nuts 12 at both sides.
@ Be sure both sides are set the same.
6.3
WEIGHT COMPENSATION SPRINGS.
The roller can support the head all the time.
However when small turns are made with the machine during work, the weight from the head
has to be reduced. If not the head is pushed sideward and damages will appear to the head
and the lift mechanism.
The spring load 2 (Fig.6.) can be adjusted by shortening or lengthening the chain 1. If the
spring load is increased, (tighter) turns are easier to make.
The spring load 2 can only be changed when the head is fully up and secured. Choose the
next chain shackle (adjust both springs evenly). The spring load also retracts the hydraulic
cylinder when the unit is lowered and the valve is opened for a little longer.
