Deadman switch
To operate the controls you must lift up the lower rain on the control handle and then you will be able to move the control
The tiller ladder is equipped with for special emergency ladder functions what are they
Override switch
emergency hydraulic power switch areal stabilizer emergency power switch
electrical failure operations
The override switch is used to bypass
Safety interlocks except the emergency stop
Where are manual override stablizer control’s found
Only on the engineer side behind fold down door
Ariel stabilizer emergency hydraulic power switch
Used when the apparatus has a total catastrophic failure this means the Ariel master in hydraulic pump are not working and more likely the truck will not be running
The aerial stabilizer emergency power switch 
Will activate the electric backup pump when engaged
Where are the manual override Ariel controls located
On the turntable inside the aerial control tower behind a latch that flips down the alarm will sound when hatch is open
When using manual override what systems are deactivated
Ariel controls in collision avoidance
Where is the warning triangle displayed
Lower right hand corner on the touch screen as a turntable controls
The emergency pump unit
Operates off the truck batteries it is use for special emergency ladder functions to stow the aerial in case of a primary pump failure
The EPU has a limited run time before Possible overheating
The EPU can operate continuously for up to 30 minutes do not run the EPU for more than 30 minutes without allowing at least 30 minutes for cooling down
How many batteries does the ladder truck have
Six
How many batteries does the EPU use
One that is why it is a limited run time
Where is the EPU switch located
Located at the manual stabilizer controls
What is the telescoping waterway itself constructed of
Anodized aluminum tubing
What is the diameter tube in the base section
4.5 inches
What is the diameter of the tube in the lower midsection
4 inches
What is the diameter of the tube in the upper midsection
3.5 inches
What is the diameter of the tube and fly section
3 inches
What is the aerial capable of discharging
1000 GPM’s at 100 psi parallel to the ladder and 90° to each side of the center
What is the adjustable pressure relief valve Preset at
250 psi
How many drains are located on each side of the ladder and what size
Two and 1.5 inches
When done flowing water what must be opened to allow water to drain from the water way
2 drains
What are the waterway seals made of
Type B polypak design will withstand pressures up to 2000 psi in temperatures in excess of 250 degrees F
Lubricating the exterior of the ladder pipe should be done using a light coat of
Automatic transmission fluid
The ladder truck is equipped with how many communication system
Three separate
Where are all intercom functions controlled
From the turntable council
The push to talk is at the intercom station the tip intercom station is
Hands-free which means all the operator must do is talk to be heard at the console
What are normal signals that engineer positions can do for audible alarm
1 beep stop
2 beeps go
3 beeps back up 
Where are two places to activate the audible alarm in the tiller cab
Floor pedal and the switch in the center of the steering wheel 
What is the generator PTO switch profile powered
The two cord reels , tiller cab AC and other functions
What does the signal buzzer for switch profile to both drivers
A secondary nonvoice means of communication
What does the heavy duty tiller cab steering column lock enable
The apparatus to be driven by only one driver in the front main cab
Where is the tiller can heater fuel level gauge located
Located on top of the heater fuel tank 
Where does the first arriving ladder place apparatus
Proceed to an advantageous location near the affected area of involved address
Position the ladder with the following in mind
Ariel placement Intended use Expected progression of the fire Width needed for jack deployment Overhead wires
Ladder placement of a single story structure and a multi story structure is
Single-story will be spotted in front of the structure in multi story it could be near the corner this permits the ladder company to place a turntable in position to reach two sides of the structure
Reasons why ladder needs to be raised (LEEEGUSO)
Ladder pipe operations Elevated rescue Elevated ventilation Egress for interior crews Gain access to upper levels Used as an extort standpipe Special rescue situations Overhead scene lighting
Fully extended stabilizer goes out ?
Approx 5 feet from the side of the ladder
The minimum the stabilizer on the working side
Fully extended
Non working side stabilizer
Does not need to be extended ( short jack)
Jack placement considerations (ACUA)
Avoid manhole covers concrete is better than asphalt undisturbed earth not sand avoid underground parking facilities
Ariel must maintain at least from powerlines and at least from high-voltage powerlines
20 ft clearance from power lines and 50 ft from high voltage power lines
Scrub area will differ depending on numerous factors
Type of ladder truck setback from the building obstructions spotting of the ladder 
Setback is the distance from the work inside of the ladder truck to the
Building
Taylor ladder with the aerial fully retracted needs a minimum setback of
30 feet roughly 15 paces from the side of the ladder to the top of the Aerial
When the nozzle located in fire mode
Located on the fourth fly section of the Ariel this allows the nozzle to be at the tip of the ladder for maximum height reach during operations
When the nozzle is placed and rescue mode
And also spend on the third upper midsection and rescue mode will be less obstruction at the tip of the ladder to make rescuing or access to a building easier
When supplying a ladder pipe within 100 feet the recommended initial PDP is
150 psi
At full ladder height expect to flow
180 psi
When pumping a ladder never exceed
200 psi
Ariel Akron automatic fog nozzle GPM
GPM 500-2000. Do not exceed 1000GPM
Ariel smoothbore nozzle
3 1/2 to 2 1/2 stream shaper and largest smooth bore tip is 2 equal to 1000 gpm
