2.4 Hitching Up

2.4.1 Hitching up a Tractor

to the SLD / Preparing for
Transport

When hitching-up the machine,

ensure that no-one is between the

tractor and the machine.

When the SLD is parked for

extended periods of time it should

ideally be left in the unfolded,

i.e. work, position for stability,

safety and ease of access for

maintenance. However, parking

the SLD in the folded position

(using the parking pins provided)

is acceptable in the normal course

of operation.

Tractor Oil Flow Adjustment:

As a general rule the tractor oil flow

rate should be set in the lowest set-

ting before starting. This can then

be increased to allow the desired

rate of operation as applicable.

This will minimise excessive oil flow

and consequent power usage and

heat generation.

1. Ensure the tractor hydraulics are

depressurised and in the locked or

closed (not float) setting.

2. Couple the hydraulic hoses to the

tractor ensuring that the two wing

hoses (yellow) are together, the two

lift circuit hoses (red) are together,

the trip-reset tine hoses (green) are

together and the roll circuit hoses

(blue) are together.

3. Connect the tractor to the drawbar

using the hydraulics to raise or lower

the height of the shackle.

4. Carefully operate the hydraulics to

lower the drawbar and tilt the SLD onto

the road transport wheels. Retract the

drawbar cylinder onto the shims and

lower the machine using the lift axle

cylinders.

5. If the machine is already folded it is

now ready for transport. If the machine

is unfolded then operate the fold circuit.

Refer to 2.6.2.

2.5 Air Brake Coupling

Procedure

Please refer to the following procedure when

coupling or decoupling any item of SIMBA

machinery fitted with an AIR brake or AIR

and HYDRAULIC brake system. Please

note that this procedure does not apply to

any machines fitted with a HYDRAULIC

system ONLY.

2.5.1 When Coupling

1. Reverse up to the machine and

connect the machine to the tractor as

instructed to in Section 2.4.1.

2. With the machine connected couple

the air lines. When coupling ensure the

yellow line is attached first followed by

the red line.

3. Your brake hoses are now attached

and are ready for operation.

4. Continue with the coupling process as

instructed in Section 2.4.1.
