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.
