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!
