7.2. MOUNTING OF HYDRAULIC or PNEUMATIC BRAKES
The forest trailer can be equipped also with brakes. See the spare parts manual how to install
hydraulic or pneumatic brakes. When the question is of the hydraulic brakes the hydraulic hose has
to be connected to the 1---function control valve of the driving vehicle. The brake power regulator is
available as an optional for the hydraulic brakes. Note that the red claw coupling is connected to the
feeding line and the yellow claw coupling is connected to the brake line in 2---line brake systems.
The brake power regulator is a standard equipment in the pneumatic brakes. In the brakes there is
not a adjustment possibility. Check the brake shoes, if necessary or when the braking effects have
weakened.
7.3. CRANE (optional) MOUNTING
The crane has to be installed on to the mounting plate on the frame. If you use crane HK 3861 and
assembly base AP3800, then you have to make bevels to the mounting plate as shown below.
Otherwise the crane will be installed normally.

8. OPERATION

8.1. PRE- - OPERATION CHECKS
D Check the oil level in the vehicle hydraulic system.
D Ensure that the trailer is correctly coupled to the vehicle, that the hoses and the hydraulic
components are correctly mounted and are funtioning.
D Before driving make sure the brakes are disengaged.
D Check the tyre pressures. If needed, increase or decrease tyre pressure. Don't exceed
recommended tyre pressures.
D Make sure that the directional control valve is in neutral position.

8.2. DRIVING

D Braking heavily will wear or even damage the brakes. Apply the brake steadily.
D If you use a hydraulic steering, do not suddenly overload the control cylinders.
D Be careful not to turn over the vehicle or the forest trailer.
D When needed traction, choose the driving direction by using the directional control valve. The
traction must be switched off by turning the directional valve to the floating position (neutral)
when the driving speed of the vehicle exceeds the traction speed produced by the pump. Pay
attention to the fact that in that case the friction rolls will rise out of the traction position.
CAUTION!
CAUTION!
CAUTION!
VARIO 101
When traction is engaged, the trailer cannot be pulled faster than
the pump's output enables. Maximum traction speed at pump
output 50l/min is 2,7km/h.
In prolonged constant traction, note the hydraulic oil heating.
DO NOT CHANGE DRIVE DIRECTION IN MOTION! Change the
drive direction only when the trailer is standing still. Changing
the drive direction in motion damages traction motors and wears
out tyres.
