5.

6.
Repeat steps 3-5 for the swing arm on the other side of the cradle.
7.
Check that the arms are correctly adjusted:
a.
Visually assess that both arms are standing at 90° degrees (vertical) while the
cradle is lowered.
b.
Close the door and raise the cradle a short distance off the ground, then
check that both arms have pivoted horizontally across the face of the bin,
standing no more than 25mm proud.
c.
Conduct a complete lifting/lowering cycle and check that the bin is held

4.3.1.3
Secondary Swing-Arm adjustment
Type-E cradles have another pair of pivoting arms called
Secondary Swing-Arms
(yellow in the above diagram) to prevent 660L/770L wheelie
b f ‘ ll v ’ wh l
being tipped. This is necessary because the Primary Swing-Arms usually retain only 1100L bins.
The Secondary Swing-Arms have similar functionality to the Primary Swing-Arms, and are
mounted on the same axle, but are moved independently by
guide collars
the above diagram). By adjusting the guide collars, the Secondary Swing-Arms can be
configured separately from the Primary Swing-Arms. They should be adjusted to suit the
second-largest bins
that are to be emptied in regular operation (typically 660L or 770L).
The procedure to adjust the Secondary Swing-Arms is as follows:
1.
Lower the cradle completely to the ground and open the safety door.
2.
Place
a
sample of the second-largest bin that is to be regularly emptied
onto the
cradle, ensuring it is centrally positioned and firm against the backplate.
3.
At the front of the cradle, use a 4mm hex key to loosen the two screws securing one
of the guide collars.
4.
Rotate the swing arm horizontal and slide it forwards on its axle until it contacts the
back of the bin, then withdraw it by 10mm.
5.
Rotate the arm back to vertical, and holding it in this position, rotate the guide collar
until its crossbar makes firm contact with the swing arm.
6.
Re-tighten the screws on the guide collar.
7.
Repeat steps 3-6 for the collar and arm on the other side of the cradle.
In some cases, the collar screws do not lock onto the axle with enough force, causing the
collar to gradually slide out of position. Should this problem

may
be drilled into the axle with a 4mm drill bit, so the screws can lock into place.
8.
Check that the arms are correctly adjusted:
a.
Visually assess that both arms are standing at 90 degrees (vertical) while the
cradle is lowered.
b.
Close the door and raise the cradle a short distance off the ground, then
check that both arms have pivoted horizontally across the face of the bin,
standing no more than 25mm proud.
