3 Overload limiter
a) Place the service lift on the lowest travel point
b) Apply the Setup load + 20 Kg from the table
depending on the tower height.
c) Push the UP button. If the lift can go up
modify the adjustment of the overload system
until it is no longer possible to go UP following
the procedure below:
1. Loosen the set screw (7) in the casing
cover with an Allen key (size 2)
2. Remove the cap (8). Place an Allen key (size
41, 150 mm long) into the adjusting screw (6)
3. Turn the adjusting screw (6) clockwise, until
the test load can be lifted.
4.Gradually reduce the trigger point of the limit
switch (4) by means of the adjusting screw (6),
until the test load can no longer be lifted: 1)
Turn the adjusting screw by 1/4 turn anticlock
wise to reduce the trigger point; 2) Press
the UP-button
d) Apply Setup load. Push the UP button and
verify the lift can go up. If not, return to b) until
the lift is able to go UP with Setup load but is
not able to go UP with Setup load + 20 Kg
e) Apply Lift WLL and verify that it can perform
the travel to the top without triggering the
overload limit. If it is not possible verify loads
used and return to b), otherwise continue with f)
f) Go back to the lowest point and apply
Overload test load.
g) Press the UP button and verify the overload is
triggered. If it is not triggered verify test loads
and return to b), otherwise continue with h)
h) Tighten the set screw (7).
i) Remove the tools.
j) Insert the cap (8) into the casing hole.
k) Fill in the “Annual inspection test report” check
point 6.9 and sign.
