8.1 Machine lowers on its own
Adjust the lowering valve by following
this procedure
• Loosen the M8 grub screw
• Leave the lowering pedal in its nor-mal
position
• Using a screwdriver slightly adjust the
valve spindle:
- Anticlockwise, to raise the lower-ing
speed.
- Clockwise, to reduce the lowering
speed and to ensure that the pump
holds the load in position.
• Lightly tighten the grub screw after eve-
ry adjustment.
• When adjustment is correct fully tighten
the grub screw.
