Fault: 1.
The engine only runs when the Start button is pushed to the bottom.
Check: 1.
Ensure that there is enough oil in the oil tank. Oil must be added if
the red piston is visible in part number 49. When adding oil, first press the piston
of the oil tank into the lower position, the piston moves about 90 mm downwards
(use the tool supplied with the machine or screwdriver, min 100 mm long).
Fill the oil tank completely, close the oil filler hole carefully.
Check: 2.
Ensure that the airpressure is sufficient by checking the compressor
pressure gauges. Requirement 5 bar / 72 psi minimum.
Check the air hoses, their connectors and possible leaks. The hoses must
be tight and should not be pressed flat. Hoses must not be so tightly bent
that air flow is prevented.
Fault: 2.
The motor runs normally when The Start button is pushed to the bottom but
the engine power does not seem sufficient.
Check: 1.
Check the compressor pressure gauges that the pressure is sufficient.
Requirement
5 bar / 72 psi.
Check: 2.
Check the air hoses, their connectors and possible leaks. The hoses must
be tight and should not be pressed flat. Hoses must not be so tightly bent
that air flow is prevented.
Check: 3.
Check the function of the rush prevention valve, part number 14 ”Air Axle”.
Remove the air in the hose and lift the motor part to the upright position.
Using a small screwdriver to move the part 14 gently up and down.
The cause of faults 1 and 2
may also be poorly filtered compressed air.
If debris have entered into the oil reservoir with compressed air, they may
cause various defects. Cleaning and adjusting the oil cleaner must be done
by an authorized service center.
Fault: 3.
The blade does not rotate, the engine does not rotate.
Check:
Unplug the machine from the compressed air supply. Then rotate the blade
manually. If the blade does not rotate by hand or rotates only with high force,
the engine or gearbox is damaged. Take the machine to service.
Fault: 4.
The blade does not rotate, the engine rotates.
Check:
Unplug the machine from the compressed air supply. Check the blade tension
using the blade key supplied with the machine. Ensure that the blade tension
is appropriate and can not slip between the flanges.
