- 51 – TES1518/E
If the hydraulic hoses are damaged replace them and continue on as described in the
operating instructions.
6.2.1 Emergency lowering of the automotive lift
• Loosen the lock nut (marked with red colour) at the valve located at the bottom of each
cylinder. This nut secures the set screw. Turn the set screw about one turn clockwise. This
has to be done at both cylinders.
Warning !
In the case where hydraulic hoses are defective, the lift will lower into the safety
ratchets, once the ratchet is engaged the lift can not be lowered any more. The
defective hydraulic hoses must be replaced to use the lift again.
• In the case where the hydraulic hoses are not defective, the ratchets can be raised off the
hydraulic cylinders manually. This can be done by inserting a wooden wedge between the
cylinder and upper part of the ratchet so that the ratchet cannot engage (see pic. 9). This
must be performed at both hydraulic cylinders.
Pic 9: supporting ratchet
• Remove motor-covering from command unit (see pic. 5)
• Loosen locking screw of emergency lowering screw at command unit (marked with red
colour, see pic. 10)
• Loosen emergency lowering screw (threaded pin) about one turn anti-clockwise to start
lowering.
Pic 10:
Position of the emergency screw
• Fasten set screw when the upper parts of the ratchets have passed the last ratchet tooth
(the ratchets can no longer engage) (see pic. 11)
• Remove supports from ratchets at both cylinders
The supports must be removed before lowering the lift to the ground. Otherwise the lift
can be seriously damaged.
