5.4 RECOMMENDED PARK POSITION

For truck mounted applications it is recommended that the monitor
be parked in a position such that the monitor's nozzle rests against
a bracket or support surface. If a support surface is not available,
run the elevation against one of its travel stops to take some of
the backlash out of the gear drive. This will minimize bouncing of
the nozzle when the apparatus is traveling. Always be sure the
monitor is properly parked before moving the truck and know the
overall height to avoid damage from overhead obstructions such
as doors or bridges.

5.5 OVERRIDE KNOBS

In the event of electrical system failure on the monitor or fi re truck
the Monsoon Monitor is factory supplied with knobs so the monitor
may be manually operated. To make the Monsoon RC more
compact the manual override knobs may be removed. The drive
shafts have a hex so an 11/16" wrench or socket may be used for
manual override. Each drive shaft also has a secondary hex at
mid shaft so the shaft may be shortened by cutting and still have a
wrenching hex. The wrenching hexes are shown in fi gure 5.5.
