Opening aid - Gas-pressurised springs:
Chapter 04: Assembling the opening aids
The gas-pressurised springs can be adjusted for force by fitting an adjustable stop.
1. First, screw the piston rod head to the frame at the bottom using the pre-fitted screw.
Only tighten the nut to a point where the screw can still be rotated!
2. Next, install the cylinder head as shown; when the lid is moved, the screw slides in
the slot, so do not tighten this nut firmly either.
3. By fixing the stop / sleeve at a variable height, it is possible to adjust the point to
which the gas-pressurised spring also slides up when opening the lid.
If the shaft cover has only one gas-pressurised spring, the point is to be chosen such
that the lid stops when opened at around 80°. It is then easy to move the lid manually
into the latch locking position. On lids with a depth of 600 mm, the stop is not
required.
If multiple gas-pressurised springs are used, it is sensible to fit the stops in such a way
that the gas-pressurised springs are used in succession. The advantage of this is that,
when opening, the lid does not open too quickly and, when closing, there is no need to
push immediately against the force of all the gas-pressurised springs. The further the
stop is moved downwards, the greater the force of the gas-pressurised springs when
opening starts.
Please note: Do not move the stop so far downwards that the piston of the gas-
pressurised spring comes into contact with the base of the cylinder!
