Operating Instructions

4.12 Parking the machine

In order to avoid damage as a result of

moisture, the machine should be parked, if

possible, indoors or under cover.

When manoeuvring the machine,

pay attention to your surroundings.

Ensure that nobody is in the

manoeuvring area (watch for

children!).

• Park the machine on level and solid ground.

• Fit chocks under the wheels

• Raise the machine and remove shims from

the lift axle cylinders.

• Lower the machine to the ground, ensuring

that it is stable.

• Remove the drawbar pin and drive forward

slowly until hitch is clear of tractor drawbar.

• Lower the drawbar to the ground.

• Switch off the tractor.

• Disconnect hydraulic lines from the tractor.

4.10 Depth Control

Working depth can be set by mid or rear roll

and/or by transport wheels. Under normal

conditions the weight of the machine will be

carried on the roll and the drawbar of the

tractor, with the main lift wheels fully raised.

Depth is set using the depth control cylinders

situated on the roll unit with shims added and

removed as appropriate. The front to rear

pitch of the machine should be adjusted as

appropriate to compensate for changes in

working depth by adjusting the amount of

shims on the drawbar cylinder.

Some conditions or finished effects may

dictate that depth control is carried out using

both the roll and the lift wheels.

Rear Roll

Use roll depth cylinder to set machine

working depth - ensure wheels are lifted

clear of ground. Use shims in the drawbar

cylinders to set chassis pitch level.

4.11 Work Instructions

Driving speed

The SLD can be driven at speeds of up to

12 km/h.

This depends on the field conditions (type

of soil, surface trash, etc.).

Drive more slowly if the conditions are diffi-

cult or a firmer finish is required.

Turning:

Before turning, the machine should

be eased out of work onto the trans-

port wheels while driving. Likewise,

it should eased back into work once

the turn has been completed.
