To install the monitor on either the truck mount flange or portable base: (Refer to figures
4.4.1, 4.4.2, & 4.4.3)
a) Turn elevation handwheel to make sure the elevation of the nozzle is above the 35°
safety stop. Verify that the elevation stop pin is down and engaged.
b) Make sure the slide bar is in the up position.
c) Hold the monitor by the top carrying handle, position monitor over base and slide
straight down.
d) Push the slide bar down and watch the pawls engage the groove in the base and the
safety plunger engage in the hole in the slide bar.

4.5 PORTABLE BASE ANCHORING
A sliding monitor can cause injury.
Remove all slack between the anchor
and base before flowing water.
Whenever the monitor is operated on the portable base, the base must be anchored
to a substantial immovable object. An attachment point is provided on the front of the
base for this purpose. A strap, with a minimum breaking strength of 3000 lbs of force,
is supplied with the portable base. A loop on the end of the strap may be placed over
the anchor point or the strap may be wrapped around an object, such as a tree, and
the snap end of the strap passed through the loop and pulled tight. Keep the entire
length of the strap as close to the ground as possible. Snap the hook
into the hole in the front of the portable base below the carrying
handle. The length of the strap may be adjusted by the sliding the
buckle on the strap. If the strap is too short to reach a suitable anchor,
it may be extended with strong rope or chain. Keep the distance
between the base and anchor point as short as possible.
WARNING
At low nozzle elevation angles the base may also require additional anchoring. The ability of a single anchor to stop sliding is a function
of the horizontal angle between the strap and water stream. When the stream is in line with the anchor any sliding will be arrested by the
anchor. As the horizontal angle increases between the anchor strap and the stream, the base can begin to slide in an arc around the
anchor point. In this situation multiple anchor points may be required.
The strap should be stored inside the monitor base when not in use. The black rubber cap on the strap will hold the strap in the base
and protect the sealing surface of the quick connect swivel joint.
