-It is prohibited to go beneath the trailer when operating the crane or trailer.
-Before driving check that no tools or equipment are located on or under the trailer.
-Do not use the trailer for work that it is not intented for.
-The load on trailer of has to be evenly distributed to prevent the trailer from tipping over.
-Check that tire pressure and axel weight are right before towing the trailer( tire pressure
suggested 1kPa).
-Use only original spare parts from manufacturer to prevent damaging the crane or trailer.
-Never put a bigger load on the trailer then is allowed by the manufacturer, otherwise the
warranty of the trailer will expire. ( MAX LOAD 1500 kg)

Manual
Crane
Before working with the crane follow these instructions:
−ALWAYS use the treilers support legs when operating the crane.
−If you use the crane without support legs the trailer can tip over or will brake down. Be
convinced that the trailer is firmly standing on the ground.
−Before starting to work with crane study carefully the functions of the leavers that operate
the crane shown on page 7.
−To prolong the life of the trailer and crane it is important to lubricate the moving parts
shown on the maintainance page 11-13.
−Never stretch the crane to full extent when fully loaded.
−Oil volume in housing box is 0,7 L .
−The oil used in the housing is GX80W90 GL4/5. Change oil at least once a year.
−Check the oil amount in the housing through a valve that is in front of housing box.
−No one is allowed to be in the working area when operating the crane(safe distance
10m)
Hydraulic unit
−Check the engine oil every time before starting the engine.
−Before connecting the loader to the tractors hydraulic system make sure that the oils are
compatible. Check the hydraulic oil level.
−Change engine oil after every 75 work/h. ( Oil used - Addinol MV1045 10W-40)
−Hydraulic units oil filter has to be changed after 300 times of using.
−Hydraulic oil used in unit is HVLP-46 Addinol.
−Ensure that the control valve’s pressure line has been connected properly and that the
return is unobstructed.
−Ensure that the hoses can move freely. Remove any transport supports and ties.
Trailer
−Air pressure in wheels is maximum 1kPa.

Before starting engine:
NB! Before starting the engine, check that all hoses from hydraulic
engine are connected correctly to hydraulic valve package. If the hoses
are not correctly connected the hydraulic system can have a malfunction
and vital parts of device can be damaged.
1. Check that oil volume in engine is in normal level(fasten the engine on steady ground).
2. To check the oil level, look at the oil meter on the oil tank.
3. Gasoline tank must be filled with right gasoline(octane 95).
4. Check that gasoline valve is in position ON.
5. Start the engine (engine with electric starter).
6. Pull the string(manual start engine).
7. After engine starts release start button (engine with electric start).

Cranes control valves operating instructions
Before you start to work, study carefully the operating principles of leavers.

Testing
Ensure that the control valve’s control levers are in the middle position. Connect the oil flow to
the loader and let oil flow through the valve for a while. Lower the support legs. Carefully
drive the loader movements one by one to their extreme positions and repeat this until the
movements are smooth. After testing the loader, inspect the joints and repair any leaks.
Check the mounting bolts of the loader and the fitting stand, and tighten them if necessary.
Check the hydraulic oil level, and top up the oil if necessary.
Be careful when bleeding air from the system. If you drive a cylinder to its extreme
position at full force, the air pressure in the cylinder will damage the seals!
Be extremely careful when there is air in the cylinders!
Practice runs
Drive through every movement with an unloaded loader, paying attention to the positions in
which the loader can hit obstacles.
Don’t forget to lift the support legs UP before moving to another place!
Move the control levers smoothly and steadily, avoiding quick and jerky movements. Learn to
use several functions simultaneously. This enables smooth, precise operation. Start off at a
low engine speed in order to avoid sudden movements. When you have become accustomed
to the loader’s movements, choose the appropriate engine speed so that operation is efficient
but you still have the movements under control.
Never move the boom to its extreme position at full speed!

DETACHING THE LOADER
Ensure that the ground under the loader is sufficiently hard and level. Ensure that there are
no extra people around and that no danger will be caused to others where the loader is to be
stored. Pay special attention to the storage location of the control valve, ensuring that, e.g it is
out of the reach of children.
Always switch the pump off before removing the quick coupling between the loader
and the vehicle!
•Lower the support legs to the desired height
•Fix the loader firmly by proper hoist
•Make sure that the loader cannot lean over
•Detach the loader from the vehicle
•Detach and cover the control valve’s quick couplings
