3.3 Connecting hydraulic hoses
•
Before connecting the hydraulic hoses, make sure that the carrier vehicle hydraulic system is
not pressurized.
•
Before connecting, make sure all connections are clean. Impurities in the hydraulic fluid can
cause severe damage to the hydraulic system.
•
Stop the motor.
•
Move the hydraulic controls back and forth to relieve any excess pressure.
•
Remove the protective covers (7:T) from the couplings and connect the hydraulic connection
as shown in figures 7 - 9.
Detaching
4
•
Observe the information from the carrier vehicle operating manual.
•
When uncoupling there is a risk of injury, e.g. due to crushing. Exceptional care is required.
•
The procedure for uncoupling the attachment is as follows:
1. Raise the attachment and move the supports to the lower end position.
2. Detach the chain from the shaft guard on the carrier machine and disconnect the
shaft.
3. Lower the attachment and stop the motor.
4. Release any excess pressure in the hydraulic system by moving all hydraulic controls
back and forth.
5. Disconnect the hydraulic hoses and fit the protective covers on the couplings.
6. Disconnect the electrical connection to the carrier vehicle.
7. Remove the locking bolts (4:P) and carefully reverse away.
Operation

5.1 Maximum brush plate operating speed
Caution:
•
The maximum speed of the shaft is 1,600 rpm. Note that when the power take-off is turned on,
the throttle lever may not be pushed further forward (see Fig. 13) than indicated by the
adhesive label (13:K) attached next to the throttle lever (13:L).
•
Section 3.1 describes how to attach the adhesive label (13:K).
•
The adhesive label (13:K) is part of the machine's safety equipment. The attachment
may not be operated without this adhesive label.
5.2 Adjusting the brush plate
5.2.1 General
•
The working height of the brush plate is adjusted using the trailing stabilizer wheel (1:G). The
working height depends on the position of the brush plate (1:B) and the degree of wear of the
brushes (1:C).
•
The plate is adjusted according to the severity of the weed growth. The working range of the
brush plate is shown in Figure (10:A). A good performance is achieved when the brush plate is
tilted slightly to the right and slightly backwards, viewed in the direction of travel.
•
Particularly good results are achieved after precipitation and in damp weather.
•
The travel speed depends on the severity of the weed growth.
