MACHINE OPERATION
Controls
Movement control
The control lever has 4 functions:
1. To put the machine in neutral to stop it or start the engine.
2. To engage the wheel drive: Gradually push the control towards the front to adjust the
speed.
3. To stop the machine, release the control.
4. To reverse, push the control to the back, beyond neutral. This can be done whenever the
engine is running and allows instant forward/reverse operation. When the control lever is
released from the reverse position, the machine automatically switches to neutral.
5. Depending on the application, work is done in forward (chip spreading) or backward
motion (hot mix spreading).
Parking brake
It is automatic. When the movement control is released, the machine is automatically
immobilized due to the hydrostatic transmission. The same applies when the engine is
stopped.
Accelerator control
By moving the accelerator lever towards the front (towards the
engine), the engine speed is increased until the maximum regulated
speed is reached. By bringing the accelerator backwards (towards the
operator), the engine speed is reduced.
There is a built-in choke located after the maximum speed, with the
lever pushed fully forward. To stop the engine, place the lever
completely to the rear, beyond the idling point.

P a g e 15 | 101
Right thickness adjustment control (A)
Push the control up to increase the spreading thickness on
the right side and down to reduce it.
Left thickness adjustment control (B)
Push the control up to increase the spreading thickness on
the left side and down to reduce it.
Gates pre-selection control (C)
Close the valves for the gates that are not to be used
Gates control
Turn towards the back to open the pre-selected gates and to the front to close them.
Handlebar height adjustment control
Hold the lock, select the handlebar height, release to re-lock.
Bridge uncoupling control
Remove the beta pin, place the control in the rear position and re-pin. In this configuration
the machine can be moved without the engine, without being able to exceed 3.2 km/h [1.99
m/h] .

BEFORE STARTING THE ENGINE
1. Check the engine oil level and top up if required. Open the fuel valve under the fuel tank.
Check that the movement control is in neutral.
2. For cold starts, push the accelerator lever completely forward to activate the choke.
3. Pull the starter to start the engine.
4. As soon as the engine starts, gradually remove
the lever from the choke position until the
engine runs without it.
Using the machine
Practise at low speed until you completely master the controls.
For normal work, the accelerator should be in the fully open position. By using the
movement control to speed up or slow down the machine during use, you can keep
maximum control.
If you use the machine at less than full engine speed in difficult conditions, the machine
will struggle and risk excessive wear.
The centre of gravity moves when the machine is loaded. Keep in mind your physical
capacities to keep yourself out of danger and be able to control the machine in all
situations.

P a g e 17 | 101
Use on a slope
EXERCISE THE UTMOST CAUTION WHEN WORKING ON SLOPES.
ASSESS THE RISKS INVOLVED BEFORE STARTING ANY WORK ON SLOPES.
Beware of rises and falls that affect the slope. Beware of holes, stones on the ground or any
other hidden hazards. Avoid surfaces that could make the machine skid.
If the operator is not comfortable or not sure of the machine’s stability, they must stop it
immediately.
The final liability for the safe use of the machine on slopes is the operator’s.
Reduce speed and be very careful on slopes, in particular when making sharp turns, to
prevent the machine from tipping over and to avoid losing control. Be extremely careful
when changing direction on a slope.
To stop the machine
Cut the accelerator to slow down the engine, cut the engine by placing the accelerator
lever in its maximum rear position.
REMARK: Carry out all adjustments when the engine is cut and the spark plug wire
disconnected.

SPREADING MATERIALS
Spreading hot mix
Place the machine in “hot mix spreading” configuration (see the “hot mix spreading” / “chip
spreading” configuration section).
Start the machine and run the engine at full speed for at least 20 minutes before starting to
spread, in order to allow the smoothing plate to rise in temperature. Too low a temperature
will cause the smoothing plate to stick to the hot mix, this will smooth incorrectly and there
will be defects in the spread product.
Spray a non-stick product, of the bio oil type, inside the hopper, on the gates and under the
smoothing plate. Repeat the operation whenever necessary (the product must not stick to the
sides). Cut the engine for this operation (risk of crushing).
Check the gates are in working order, warm them if necessary in the event of sticking.
Check that the machine gates are closed and fill the hopper by gravity at the supply truck gate.
Do not exceed the maximum load indicated on the manufacturer plate (500 kg [1,102
lbs] MAX).
Move the machine to the work area, place it on the smoothing plate, adjust the spreading
thickness using the right and left jacks. Check the requested height using the graduated index.
Open the number of gates corresponding to the required width and push the movement
control gradually towards the back without pushing the handlebar. The machine levels on its
own. Check the applied thickness and correct using the jacks if necessary.
As soon as the product is no longer visible in the hopper and distribution box, close the gates
and continue to spread in order to spread the hot mix present in the machine’s distribution
channel before reloading. Carefully clean the gates, the distribution channels and the
smoothing plate when work is complete in order to facilitate use on the next site.

P a g e 19 | 101
Chip spreading
Place the machine in “chip spreading” configuration (see the “hot mix spreading” / “chip
spreading” configuration section).
Position the chip spreading stop bar (2 available positions, depending on the chip size).
Fit the chip spreading distributor. Fixing from below, do not place the hands inside the
gates.
Only use the machine in the high position to avoid damaging the distributor.
Check that the machine gates are closed and fill the hopper by gravity at the supply truck gate.
Do not exceed the maximum load indicated on the manufacturer plate (500 kg [1,102
lbs] MAX).
Move the machine to the work area, use the machine in forward only. Select the number of
gates corresponding to the required width. Move forward and open the gates to start chip
spreading, the dosage will be obtained depending on the machine’s forward speed.
As soon as no product is visible between the hopper and the distributor box, close the gates
and reload.

P a g e 20 | 101
“Hot mix spreading” / “chip spreading” configuration
Before starting, you must prepare your machine to the type of spreading required: “hot mix
spreading or “chip spreading”.
Two elements have to be adjusted:
The chip spreading stop bar
The chip spreading distributor
You need:
A 14 « Allen » key
“Hot mix spreading” configuration:
The chip spreading stop bar is in position High (CAUTION : must be done on both sides)
The chip spreading distributor stays on the hopper
“Chip” spreading:
The chip spreading stop bar has to be positioned depending on the chip size (CAUTION :
must be done on both sides)
The chip spreading distributor is placed under the application table.
