Dirt in load control valve or 
faulty valve. 
 
 
Dirt in emergency lowering 
valve or faulty valve. 
 
 
Emergency lowering valve(s) 
don’t work when emergency 
lowering button is pushed. 
 
 
Lift cylinder seals faulty. 
 

 
Clean valve with compressed 
air, if that doesn’t help change 
valve. 
 
Clean valve with compressed 
air, if that doesn’t help change

Check emergency lowering 
fuse, if all right check also 
emergency lowering valve(s) 
separately. 
 
Change lift cylinder seals. 

 
Outrigger gives in. 
 

 
Make sure that the ground 
doesn’t give in. 
 
 
Air in outrigger cylinder(s). 
 
 
Dirt in outrigger cylinder check 
valve. 
 
Faulty check valve. 
 
Faulty outrigger cylinder seals. 
 

 
Put extra support plates under 
the outriggers or move to 
another place. 
 
Drive outriggers up and down a 
couple of times. 
 
Clean valve with compressed 
air. 
 
Change valve. 
 
Change outrigger cylinder seals. 

 
Platform tilts backwards by itself

Dirt in load control valve of self 
levelling cylinder or faulty valve. 
 
 
Faulty self levelling cylinder 
seals. 

 
Start the engine/motor, drive the 
platform to extreme end 
positions by using the lever no.

oesn’t 

help, do the air bleeding of the 
platform self levelling system 
(there are bleeding screws in 
the self levelling cylinders). 
 
Clean valve with compressed 
air. If that doesn’t help, change 
the valve.
