The CROSSFIRE monitor can be used on either a truck mount adaptor, Extend-A-Gun or portable base. Installation on either base
makes use of a quick connect swivel joint. The use of each base and the quick connect joint is explained in the following sections.
Two pawls, actuated by the slide bar, engage in the base swivel to make the quick connect joint. A safety plunger engages in the slide
bar to prevent accidental unlocking of the slide bar when the monitor is under pressure.
To install the monitor on either the truck mount flange or portable base: Refer to figures 4.2.1, 4.2.2, & 4.2.3.
Side-to-side rotation is accomplished by rotating the monitor on its base. The rotational position can be locked by moving the rotation
lock lever to its down position as shown in Figures 4.4.1 & 4.4.2. Before the monitor is removed from the base, the rotation lock should
be manually disengaged. A small spring holds the rotational lock in the unlocked position. When not rotating the monitor on the base,
keep the rotation lock locked.
To remove the monitor from it’s base:
• Stop all water flow.
• Depress the safety plunger and lift the slide bar which will disengage the spring loaded pawls from the groove in the base.
• Lift the monitor straight up off the base by the handle on top of the monitor.
