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.

Wrenching Hexes on Drive Shafts
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.
