1.1. OILS AND GREASES
1. Always use only the types of oils recommended by the manufacturer. If these recommendations
arenotfollowed,itmaydamagethemachineorcausethemachinenottooperateproperly,
which again may cause serious bodily injury or material damage.
2. Do not mix different kinds of fluids or oils together.
3. Remember that not all bearings are alike. Each bearing has its own characteristics and
lubrication requirements. Follow the instructions provided by the manufacturer.
4. Use the control equipment with special care until the hydraulic oil has reached the correct
temperature. Warm up the hydraulic oils in accordance with the instructions provided by the
manufacturer.
2. SAFETY INSTRUCTIONS FOR THE HYDRAULIC
CIRCUITS
1. Only trained and experienced technicians are allowed to install, repair or service hydraulic
equipment.
2. Check the equipment for possible leaking. All leaks in the hydraulic system must be repaired
before the equipment is taken into operation. Check all hydraulic hoses, especially those which
have to bend in use and replace the hoses as necessary. Check that all the safety caps and
filling plugs have been closed tightly.
3. Check that all the safety equipment such as pressure control valves, pressure gauges etc. are
in place and in operating condition. You must know how to use them. The safety systems
must never be bypassed.
4. All hydraulic hoses, which are in bad condition or leaking must be replaced.
5. It is forbidden to change the pressure values of any operation.

6. Check daily and always after damage the most important parts of the hydraulic system. Repair
the damaged parts immediately.
7. Clean the surface of the components to be repaired. Do not use dissolvents when cleaning the
parts.
8. Do not try to do repairs which you do not master.
9. Never try to do repairs in the hydraulic circuit, when the system is pressurized. A compressed
oil jet may penetrate your skin and be lethal.
10. Do not use the equipment if the system has a leaking hose.
11. Make sure that all joints are tight and that the lines have not been damaged.
12. Do not work underneath a machine or component, which is only held up hydraulically. Use
separate supports when servicing or repairing.
13. Do not disconnect the cylinders of the machine or their counter valves before the machine has
been supported well.
14. The length and quality of the pipe connectors and hoses must correspond to the set
requirements. When replacing or repairing the hoses, use original spare parts or hoses and
connectors, which are in accordance with the manufacturer’s recommendations. It is to made
sure, in particular, that the pressure classes of the hoses and connectors correspond to the
operating pressures.
15. All changes in the equipment require a written permit from the manufacturer.
16. Hydraulic oils do not normally evaporate easily. However, hot oil, splashes and oil fog (under
pressure) are danger factors. Small amounts do not normally cause intoxication when inhaled
or swallowed. Old, dirty oil is more dangerous than new oil.
17. If you get oil in your eyes, rinse them with abundant water and see a doctor.
18. Occasional skin contact is not normally harmful if the skin is healthy and there are no open
wounds. You can wipe or wash the oil from the skin. The problem is repeated skin contact,
which results in dry and chapping skin of the hands. The oil dissolves the natural protective
grease layer off the skin and the skin gets small cuts and scratches easily. Hydraulic oil that
penetrate the scratches can cause an inflammation and a rash.
19. If you cannot avoid splashes or skin contact, use safety gloves, glasses and clothing as
necessary. Do not use oily clothes.
20. Hydraulic oil must not get into the environment, because it may pollute the water system and
groundwater. However, if it is necessary to work in ecologically sensitive areas, mineral oil
should be replaced by vegetable oil (rape---seed oil).
21. Store the oil in a closed vessels provided by the factory. Try to get the oil directly from the
vessel into the tank.
22. If you must pour oil into other containers, it is important that they are clean. Also the caps,
funnels, filters and filling holes must be clean.
23. Do not store oil out---of---doors to prevent water from condensing in the oil.
24. Always drain waste oils into a vessel and not into the environment.

7. MOUNTING
7.1. MOUNTING
1. If the trailer is not a ready---made one, the installation must begin by assembling the trailer. When
the base frame has been assemblied, the hydraulic hoses must be lead through the base beam
to the connectors of the back part of the trailer. See the spare parts book the base frame
assembly and connection of the hydraulic hoses.
2. Fix the trailer to the trailer hitch of the vehicle.
3. Connect the hydraulic system of the trailer to the hydraulic system of the vehicle. Connect the
optional hydraulic steering to vehicle hydraulics.
4. For choosing the drive direction of a trailer with traction, the vehicle requires a double---acting,
floating position directional control valve with two 190 bar check valves. The valve has three
positions for traction: forwards, neutral and backwards. See the hydraulic schema below.

7.2. MOUNTING OF HYDRAULIC or PNEUMATIC BRAKES
Theforesttrailercanbeequippedalsowithbrakes.Seethesparepartsmanualhowtoinstall
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.
Otherwisethecranewillbeinstallednormally.
8. OPERATION
8.1. PRE--OPERATION CHECKS
DCheck the oil level in the vehicle hydraulic system.
DEnsure that the trailer is correctly coupled to the vehicle, that the hoses and the hydraulic
components are correctly mounted and are funtioning.
DBefore driving make sure the brakes are disengaged.
DCheck the tyre pressures. If needed, increase or decrease tyre pressure. Don’t exceed
recommended tyre pressures.
DMake sure that the directional control valve is in neutral position.
8.2. DRIVING
DBraking heavily will wear or even damage the brakes. Apply the brake steadily.
DIf you use a hydraulic steering, do not suddenly overload the control cylinders.
DBe careful not to turn over the vehicle or the forest trailer.
DWhen 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.
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.
CAUTION!
In prolonged constant traction, note the hydraulic oil heating.
CAUTION!
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.
CAUTION!

8.3. ADJUSTING THE COMPRESSION OF THE TRACTION ROLLERS
Adjusting the traction rollers compression is carried out by two valves.
DOpen the valves fully open. For initial setting turn the restriction knobs 3---4 rounds in closing
direction. If necessary to adjust the rollers compression turn the knobs to the opening or closing
direction.

8.4. USE OF THE BRAKE POWER REGULATOR (PNEUMATIC)(STANDARD EQUIPMENT)
The brake power regulator is used to adjust the pneumatic pressure going to the brakes, thus
adjusting the brake power. The regulator has a handle with three positions; empty, half and full load;
representing trailer’s state of load.

8.5. USE OF THE BRAKE POWER REGULATOR (HYDRAULIC) (OPTIONAL)
The brake power regulator is used to adjust the hydraulic pressure and hydraulic flow rate going to
the brakes thus adjusting brake power. Flow rate which goes to the brakes is adjusted in the flow
control valve (1). The pressure reduction valve (2) restricts the pressure going to the brakes to a
maximum 150 bar value.

9. LUBRICANT RECOMMENDATIONS
When lubricating or servicing the trailer, turn off the vehicle. Never attempt to clean, lubricate or
service the trailer while it is in motion.
Ensure regularity of lubrication by following the lubricating schedule.
Inspect equipment daily for signs of failures or beginning of failures.
Use proper tools for service.
Keep flammable materials away from heat, sparks and open fire.

13. VARIO 101 VARIATIONS
One of the best characteristic of the VARIO 101 is it’s variation, which happens simply and easily by
changing moduled parts. For instance, if you have purchased a forest trailer, which is a basic
