shaper be used with this monitor. The short length of the 282-A helps to minimize
stress on the discharge elbow gearing.
When the 8297 RF monitor is installed on a fire apparatus used in cold climates, a
drain valve should be provided in the riser pipe that supplies the monitor. The riser
should be drained immediately after each use during cold weather to prevent freezing
and possible damage to the monitor and piping. The discharge portion of the monitor
can be drained by simply lowering the discharge elbow below horizontal and allowing
the water to drain through the nozzle.
To reduce possibility of damage to the monitor by contact with overhead doors,
branches, etc, the nozzle discharge should be kept at the lowest possible angle.
B. Portable Monitor Mode
Carrying the upper monitor assembly on the truck mount adapter allows for its use as a
deck gun while the portable base and hose line(s) are being deployed. Determine the
portable base location (keeping in mind the need for a substantial stationary object to
which the safety strap can be attached that is in line with the intended stream
direction). Remember that the nozzle reaction force can be as high as 900 lbs.
1. Prepare the portable base for use by simply rotating each of the four folding
legs into its locked position, starting with the two rearmost legs. It is very
important that the legs be in the locked position prior to initiating water flow.
2. Anchor the portable base with
the safety strap (see Figure 18).
The safety strap should be
attached to the portable base at
the carrying handle support post
on the front leg bracket and
secured around a substantial
stationary object. The stationary
object, such as a stake, fence
post, etc., should be positioned
between the Stinger RF
® monitor
and the intended target. The leg
bracket of the portable base
should point directly at the
stationary object and the intended
target. The monitor should never
be used with any slack in the
safety strap. If no suitable object
is available, the Elkhart
81460001 anchor kit must be
used.

3. Attach the hose(s) to the portable base. To minimize the possibility of the
charged hose lines moving the monitor, the supply hose should be kept
straight in line with its respective inlet port for a distance of at least ten feet.
4. Disconnect the power/charging cable by rotating connector nut approximately
¼ turn. Remove the upper monitor and nozzle assembly from the deck mount
