4.1.3. Check the condition and fastening of the battery and wiring
Check the condition and correct fastening of the battery. Perform visual inspection of all
electric wiring.
4.1.4. Check the levelling system
Aso-calledSlaveCylinderSystemisappliedfor
levelling of the platform. The slave cylinder under
the platform is controlled by a master cylinder.
The platform keeps its level position only if the
valves in the system are tight.
The levelling system comprises of the following parts:
1. Master cylinder
2. Slave cylinder
3. Load regulation valve
4. Double load regulation valve
5. Electric directional valve
If the platform, viewed by the operator, drifts forwards, the reason can be:
• aleakintheslavecylinderdoubleloadregulationvalve(onthepistonrodside)inthe
directionoftheelectricdirectionalvalve(whichisnottight)
• an internal leakage in the cylinder
If the platform, viewed by the operator, drifts backwards, the reason can be:
• aleakintheloadregulationvalve(3)onthepiston(bottom)sideoftheslavecylinderin
thedirectionoftheelectricdirectionalvalve(5)(whichisnottight)
• an internal leakage in the cylinder
Theleakwillcausedriftingoftheplatformuntiltheloadregulationvalve(23)underthe
platform is closed. The closing is caused by dropping of the pressure on the piston rod side
to the opening ratio, which is 5:1
Air in the levelling system causes inaccuracy during levelling of the platform.
If the valves are not tight, refer to the service instructions for checking the load regulation
valves.
Settings of the load regulation valves:
• theopeningpressureofthedoubleloadregulationvalves(20)is25MPa(250bar)
• theopeningpressureoftheloadregulationvalve(23)undertheplatformis21.5MPa
(215bar)
Do not change the preset values.
