13.1 Test the pneumatic and hydraulic
system
The pneumatic connections must be established
on-site by the user.
1.
Only connect the pneumatic line to the pneu-
matic female coupler.
2.
Set the air pressure on the manometer to 6 ... 8
bar.
3.
Set the main switch to ON.
4.
Move the unloaded lift to full rise and the bottom
position several times using the Up and Down
buttons. This will completely remove any air
pockets in the hydraulic system.
5.
For variants with rolling jacks, move the unload-
ed rolling jacks up and down several times.
6.
Carry out a visual inspection of the hydraulic
and pneumatic system. In doing so, check all
lines, especially the couplings. No leaks must
be found.
7.
Lower the lift and rolling jack completely and
check the hydraulic oil level. This must also
correspond to the maximum level.
8.
Finally check that the hydraulic and pneumatic
hoses and components are fitted securely.
13.2 Test the safety mechanism
Test the
“Lower in the danger zone” Function
1.
Raise the main lift around ½ m with the Up but-
ton.
2.
Push the Down button. The lowering process
must stop at a height of around 120 mm (foot
protection).
3.
Push the Down button and Lock button together
until the main lift has been lowered completely.
A buzzer sounds constantly during the lowering
process.
4.
Test the safety shut-off for the rolling jack in the
same way.
Test the "Anti-
Misalignment“ on the rolling jacks
5.
Raise the rolling jacks with the Up button.
6.
Mask the photosensors between the runways.
7.
Push the Down button (whilst turning the selec-
tor to main lift and rolling jack respectively).
The Down function must be deactivated. Neither
the main lift nor the rolling jacks may be low-
ered.
8.
Remove the adhesive strips on the photosen-
sor.
Test the "Slack cable
” function
9.
Lock the main lift to the latch bars with the Lock
button. Press the button until the cables are
completely slack.
10.
Push the Electronic Alignment Control button
(
Chapter 6) together with the Up button until
the cables are tensioned and the buzzer switch-
es off.
Test the “broken cable” function
1.
Ensure that no vehicle is on the lift or the rolling
jacks (lift unloaded).
2.
Raise the main lift by around 1 m with the Up
button.
3.
Place a wood block under a cross beam directly
next to a lift column and lower the main lift with
the Down button.
4.
Lower the main lift onto the wood block, until the
lift column cable is slack.
The lowering process must now automatically
stop and the locking latch (lock cams into the
latch bar) must engage.
An alarm sounds. All functions on the control
unit, with the exception of the Rolling Jack
Down function must now be out of order.
5.
Push the Electronic Alignment Control button
(
Chapter 6) together with the Up button until
the cable is tensioned again and the buzzer
switches off.
6.
Now carry out the test (steps 2 to 5) on the oth-
er lift columns.
