2. Raise the slide plate until the button clicks into place.
WARNING
The attachment could fall off the truck if the
quick hook is not properly installed.
Slide plate must click into place. If the slide
plate does not click into place because the
truck carriage prevents the slide plate from
being raised up high enough, install shims
between the attachment and the body of
the quick hooks.
4.6 Hydraulic Connections
1. Before connecting the truck hydraulic system to the
attachment, the system
must
be purged through the
filtration system. This will eliminate any contamina-
tion that might exist in the auxiliary hydraulic system
of the truck.
2. Purge the system by installing a jumper line and
operating each hydraulic function (clamp, rotate
and side shift, if equipped) in each direction for a
minimum of 30 seconds. (Figure 4-7)
Hoses should meet or exceed SAE100 RI Type AT,
with maximum working pressure of 3,000 psi for all
attachment functions.
