4.0 OPERATING INSTRUCTIONS
To deploy the Extend-A-Gun VP:
1. Raise the waterway by selecting the UP position of the Deck Monitor Switch on the pump panel. This will unlock the valve hand
wheel and illuminate the Deck Monitor Extended indicator light in the cabin.
2. Open the valve using the manual hand wheel.
To stow the Extend-A-Gun VP:
1. Fully close the valve using the manual hand wheel. This will unlock the waterway control.
2. Retract the waterway by selecting the DOWN position of the Deck Monitor Switch on the pump panel. When the waterway is fully
retracted, the Deck Monitor Extended indicator light will shut off.
3. Verify water is fully drained following use to avoid possible damage due to freezing
4.1 OPERATION BELOW FREEZING TEMPERATURES
The apparatus that the Extend-A-Gun VP is mounted to may be stored in sub-freezing conditions. Ice may temporarily prevent the
Extend-A-Gun VP from extending until heat in the pump compartment has melted the ice.
4.2 MANUAL OVERRIDE
The Extend-A-Gun VP is equipped with a manual override pin to lock the waterway in the raised position in the event of damage to the
Truck or Air System to which the unit is connected.
To engage the Manual Override:
1. Remove one E-Clip and the clevis pin from the clevis at the top of the pneumatic cylinder. Store these parts in a safe place.
2. Lift the monitor by hand to the fully raised position.
3. Remove the manual override pin from the STORED position.
4. While holding the monitor in the fully raised position, insert the pin through the center hole of the bracket and into a small pocket
on the inner tube (LOCK position).
To disengage the Manual Override:
1. Support the monitor.
2. While continuing to support the monitor, remove the manual override pin from the LOCK position.
3. Slowly lower the monitor by hand to the fully retracted position and set the upper bracket into the clevis of the pneumatic cylinder.
4. Install the manual override pin back into the STORED position.
5. Install the clevis pin through the holes in the clevis and upper bracket, then install the E-Clip.
Figure 4.2
NOTICE
Do not exceed 10 ft-lb / 13.5 N-m torque to the valve driveshaft (60 lb / 27 kg applied to the knob of a
4" hand wheel). Excessive torque may damage the driveshaft and render the valve inoperable.
NOTICE
Built in safety devices prevent the valve from being opened unless the waterway is fully raised, and
prevent the waterway from retracting unless the valve is fully closed.
CAUTION
Failure to support the weight of the monitor while installing or removing the override pin may result
in injury or equipment damage due to uncontrolled movement. Always support the monitor and
slowly raise and lower when installing or removing the manual override pin.
CAUTION
Damage may occur if the truck drives under a low hanging object while the Extend-A-Gun VP is
extended. Drain water from the piping and retract the Extend-A-Gun VP before moving the
apparatus.
