3.3 REMOVING MONITOR TOP FROM BASE
3.4 SIDE-TO-SIDE ROTATION AND ROTATION LOCK
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 3.4.1 & 3.4.2. 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:
a) Stop all water flow.
b) Depress the safety plunger and lift the slide bar which will disengage the spring loaded pawls from the groove in the base.
c) Lift the monitor straight up off the base by the handle on top of the monitor.

The handwheel controls nozzle elevation (Figure 3.5.1). Clockwise rotation of the wheel will
raise the nozzle and counter-clockwise rotation of the wheel will lower the nozzle. A spring
loaded stop pin limits the nozzle elevation to 35° with respect to the base.
3.5 ELEVATION CONTROL AND STOP PIN
A sliding monitor can cause
injury.
When
used
on
a
portable
base,
keep
the
horizontal angle between the
water stream and the anchor
strap as small as possible. At
large angles the base can
slide in an arc around the
anchor point.

Operating on a portable base below this safety stop is DANGEROUS. Do not operate on portable base
below safety stop. Injury or death can occur if the monitor and base slides or lifts off the ground.
DANGER
When mounted on a truck base, the nozzle may be lowered below the 35° safety stop by pulling out the stop pin and rotating the
handwheel below the 35° stop. When the nozzle is raised back above 35°, the spring loaded stop pin will snap back into position
automatically limiting the elevation of the nozzle with respect to the base to 35°.
