Lowering The Cab Manually

Clear all personnel from the cab area. Pull release for redundant mechanical stay arm to raise redundant mechanical stay arm off of cylinder rod. If unable to release redundant mechanical stay arm from the cylinder, the cab may need to be slightly raised. Hold redundant mechanical stay arm release cable until cab moves downward enough so the redundant mechanical stay arm won’t catch the end of the cylinder.

Keep all personnel clear of pinch point when lowering the cab to prevent injury.

Turn “Manual Lower Valve” (see Figure 2-16) on the cab tilt pump counter clockwise to manually lower the cab. Lowering of the cab may be stopped by turning the “Manual Lower Valve” on the cab tilt pump clockwise until tight. Do not attempt to drive the unit when the “Cab Not Locked” message is displayed. The cab is not locked when this message is displayed. Tighten “Manual Lower Valve”, by turning valve clockwise, after cab is lowered and locked. Tilt front jacks, if equipped, back to vertical position and secure with lock pins. Return front bumper components to normal “in use” positions.

Stabilizer Controls

Overriding of any interlock system must only be done when all consideration is taken for the stability of the vehicle and safety of all persons and equipment. Stability of the vehicle must be a major safety concern of the operating personnel at all times. If the vehicle must be used with the stabilizers not fully extended, special attention must be paid to the stability of the vehicle.

Positioning Vehicle at the Scene The purpose of this section is to give basic instructions on how to properly set up the vehicle for tower operation. Though it is impossible to create a procedure to handle every situation en- countered at a fire scene, following these instructions will give the operators a solid, safe base to start. Position the vehicle in a location free of overhead obstructions and best suited for ladder operation. The vehicle can be positioned facing uphill or downhill. In either condition, the vehicle must be capable of being leveled to within the following safe operating limits:

Safe Turntable Operating Angles at Full Load 0° - 5° Side-to-Side 0° - 5° Front-to-Back

Aerialscope II 3-16 7/2013 Section 3 Seagrave Fire Apparatus, LLC Aerialscope II

Surface must be firm and capable of support- ing 75 psi to support stabilizers. Do not set up over manhole covers, storm drains or underground parking facilities that do not meet these requirements. Never set up stabilizers shoring’s across ditches, culverts or any other surface opening.

Operating the aerial device on road grades greater than 8.5° will cause serious injury to the operators and personnel or equipment near the vehicle.

During long engine idling periods with the transmission in neutral, the engine coolant temperature may fall below the normal operating range. Incomplete combustion of fuel is the end result of this condition, which can cause crankcase dilution, formation of lacquer , or gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine.

Vehicle Stabilizers The vehicle stabilizers consist of four jacks (two front and two rear) and two center stabilizers.

Front Jacks (2) Stabilizers (2) (1 each side) (1 each side) Rear Jacks (1) (1 each side)

Figure 3-15. Location of Stabilizers (Applicable to both 75’ and 95’)

Set-Up For Aerial Operation Setting The Jacks and Stabilizers

Never operate the platform without first setting the jacks and stabilizers, and stabilizing the vehicle. Always use chocks at front wheels.

• Be sure the area on both sides of the vehicle is clear of people or obstructions which could result in injury or damage before operating the ground stabilizer.

• When setting up on an incline leave tires in contact with the ground surface and use wheel chocks.
