4) Aerial Operation

This Truck comes with a 3-section telescopic boom that has a lightweight ladder mounted to it.
The aerial boom features a 1000 GPM masterstream on its tip.
In order to power the Aerial Boom you have to make sure that the engine of the truck is turned on.
Movement of the boom is only possible once the outriggers have been fully extended to stabilize the truck.
The outriggers can only be retracted when the aerial boom is in its resting position. To quickly return the aerial boom click on the joystick.
The aerial operator stand is at the rear end of the truck. You can 'sit' on the control panel in order to start controlling it.
You can either click directly on the controls panel elements in combination with your keyboard or use the Modular HUD.
The outriggers can be extended and retracted by using the EXT and RET buttons on the rear control panel.
The aerial boom control unit has a basic collision avoidance protection.
This means that the turntable can only be rotated once the aerial boom has been sufficiently raised in order to clear the cab and lightbar.
Also negative elevation is only possible while the aerial boom is pointing towards the rear area of the truck.
The turret can only be moved from side to side when it has been fully unfolded from its stored position.
There is the option to automatically align the rungs of the lightweight ladder that is mounted to the aerial boom.
This keeps the sections of the boom moving after the input has been released until an alignment position has been reached.

Step-By-Step Setup Guide

- Stop Truck and apply Parking Brake
- Ensure Engine is turned on
- 'Sit' on rear Control Panel
- Confirm Main Power Light is On
- Fully extend outriggers
- Confirm Outriggers Deployed Light is On
- Operate Aerial Boom as needed
- Click on Joystick to Auto-Stow Aerial Boom
- Fully retract outriggers

Aerial Master Stream

In order to utilize the Aerial Master Stream you have to make sure that the pump is running.
To turn the pump on click on the Power-Take-Off (PTO) switch on the left side of the cab dashboard and switch it from Road to Pump.
Either sit in the drivers seat and switch to the 4th gear or simply click on the manual gear shift stick to switch into 4th gear.
Confirm that the displays on the pump panel are lit up and functional.
If no external water source is used click on the Tank-To-Pump valve on the right side of the pump panel to use the internal water tank.
Now you can use the Master Valve on the rear of the truck to open up the Aerial Master Stream and start spraying water.
Please note that water will only start spraying once the turret has been moved from its folded position.
