6.2.5 OPERATOR STATION PANELS
The operator stations are all equipped with the same monitor movement functions. From the operator stations, the operator can
command the monitor up, down, left, right and command the nozzle pattern shaper from fog to straight stream. Operator stations
supplied with the membrane switch, shown on the left below, allow the operator to program and perform the oscillate and stow features.

6.2.6 OVERRIDE KNOBS
In the event of electrical system failure on the monitor or fire apparatus, the Tornado RC
Monitor is factory supplied with override knobs so the monitor may be manually operated.
If desirable, the override knobs may be removed. The drive shafts have a hex so a
wrench or socket may be used for manual override. The wrenching hexes are shown in
figure 6.2.3.

6.3 RECOMMENDED STOWING POSITION
For truck mounted applications, it is recommended that the monitor be stowed in a
position such that the monitor's nozzle rests against a bracket or support surface. This
will minimize bouncing of the nozzle when the apparatus is traveling. Always be sure
the monitor is properly stowed before moving the truck and know the overall
height to avoid damage from overhead obstructions such as doors or bridges.
