• Loosen security screw that secures the set screw for emergency lowering (marked with red
colour) in the hydraulic main bloc (located in the command unit) with a hexagon socket
screw key (see pic.7).
• Loosen the set screw until the lowering procedure starts.
• With danger close the emergency lowering screw at the operating unit.
• Fasten set screw when the upper parts of the ratchets have passed the last ratchet tooth and
the ratchets cannot engage anymore.
• Remove the supports from ratchets.
The supports must be removed before lowering the lift to the lowest position. Otherwise
the lift can be seriously damaged.
• Continue lowering the lift (loosen set screw again) until the lift has reached its lowest
position.
