4.8 DRAINING RESIDUAL WATER
There is no drain on the Tornado monitor itself. A drain valve should be installed on the piping to which the monitor is attached.
5.0 OPERATING INSTRUCTIONS
5.1 MANUAL (TILLER) MODEL SPRAY TRAJECTORY ADJUSTMENT
On the Tiller Bar model the horizontal rotation is changed by pushing or pulling horizontally on the Tiller Handle. Elevation is changed by
moving the Tiller Handle up or down. Twisting the Rotation Locking Knobs clockwise will increase the drag on the swivel joints to “lock”
the monitor in a particular direction.
5.2 OPERATION OF OSCILLATING MONITORS
5.2.1 HORIZONTAL ROTATION CONTROL
A handwheel controls the monitor’s horizontal rotation direction. Clockwise rotation of the handwheel moves the nozzle to the left and
counter-clockwise rotation to the right. Approximately 8.5 turns of the handwheel will give a 90 degree change in horizontal rotation
direction.
5.2.2 ELEVATION CONTROL
A handwheel controls the monitor’s elevation direction. Clockwise rotation of the handwheel raises the elevation and counterclockwise
lowers it. About 13 turns of the handwheel will give the complete 135 degree elevation travel range of the monitor.
5.2.3 TO ENGAGE THE OSCILLATING MECHANISM
If the nozzle moves freely left to right by hand, the oscillating
mechanism is not engaged. To engage, ensure the black knob on the
side of the oscillator is released, and move the nozzle from one side to
the other until the black knob clicks into the groove on the spring
canister. The minimum flow required to oscillate is 175 gpm (650 L/
min).
The oscillating mechanism is equipped with a safety device that
prevents damage to the gear train in case the oscillator comes in
contact with an object. The safety device will allow the mechanism to
continue to oscillate the portion of its sweep path not blocked by the
obstruction. The safety mechanism also allows the oscillating
mechanism to sweep vertically without disengaging the oscillator.
Once obstruction is removed, sweep pattern will return to normal.
WARNING
Monitors, valves, and piping may be damaged if frozen while containing sufficient amounts of
water. Such damage may be difficult to detect visually and can lead to possible damage, injury, or
death. Equipment that may be exposed to freezing conditions must be drained immediately
following use to prevent damage.
CAUTION
Structural damage from corrosion can result from failure to drain appliance between uses. Damage
from corrosion can cause injury due to equipment failure. Always drain appliance between uses.
WARNING
Debris in the nozzle may cause off center nozzle reaction. Injury or damage from spinning or
sudden movement of the monitor could occur. To reduce the risk of an out of control monitor:
• Always check for waterway obstructions before flowing water
• Always keep the rotation lock tight when not rotating the monitor
• Always keep one hand on the tiller handle when loosening the rotation lock
• When 360° rotation is not needed, install horizontal rotation stop bolts to limit monitor travel
DANGER
Modifying this oscillating mechanism to fit any other monitor will cause the reaction force of the
nozzle to be unaligned with the center of rotation. An unaligned monitor may spin very fast with a
very high force, which can result in serious injury or death. Do not modify the oscillator to fit any
other monitor.
CAUTION
The oscillator unit contains moving parts that can pinch fingers and hands when the unit is in
operation. Keep hands and fingers away from the moving parts of the oscillating unit when water is
flowing.
