Tweety Operation Manual

Tweety Operation Manual

Refurbish History

Motor

1) Cummings Diesel (V6), 19842) Red Line 3000 (hums at 2800)3) Top Speed 60 MPH

Oil

1) Shell Retilla Diesel Oil2) Dip stick, normal location, screw dipstick type

Rear Differential

1) Still is a 1951, and was originally designed for V12 dual Carb gasoline motor

Body

1) Original Body was 1951 LaFrance2) Refirb by SuperVac:

Changed Open cab to four person enclosed for rollover protection

Cab windows are necessary for cab integrityBoth rear boxes added to include storage spaces (six

compartments, and rear compartments)Running boards changed to aluminum for less weight

Chassis

1) left as original chassis by SuperVac

Booster and B-Foam tank

Booster and Foam tank are one plastic tank with two cells: United Plastics Tank, CA. company.1) 300 gallons water2) 220 (Class B) gallons foam: 3M 3/6% ATC; 10 -15 years old, but has been sealed

A - Foam Tank

1) A-Foam 55 gallons, sits below the proportioner, and is portable, proportions not educts.2) Operation of A-Foam system:

1) Attack line pulled and flowing Start motor2) Three position switch, adjacent to percentage valve, (flush, prime,

run) turn to prime, squeeze bulb to prime3) Percentage valve selects: 0 -1% (check to verify) Run up motor to

full throttle4) Make sure quarter turn valve (orange handle) is open5) After foam is in the pick-up tube, turn the three position valve to

"run"6) Flow the line 7) When finished:

a) close pick-up tubeb) turn indicator to flushc) flow until clear

3) Leaks may occur at the pick-up tube; crack in pick-up tube (check fill tower for cracks)

B-Foam Operation

1) The B-Foam system is an eductor2) The manufacturer is from Williams Fire Control (bought as a package); package designed to deliver 1000 gallons per minute at 3%3) The nozzle is a self-educting nozzle: 1000 gpm nozzle; can use white/clear hose and drop into 55 gallon drum for more foam delivery 4) B-foam drain is above differential housing: quarter turn valve (verify)

Operation of system:a) Establish water supplyb) Put engine in pumpc) Quarter turn (blue) valve at base of master stream supplies water for

master streamd) Open (green) quarter turn valve at base of master stream

Pump Operation

1) Arrive on scene2) Set microbrake3) Clutch engaged4) Pull PTO (on dash above shifter, silver t-handle), is quarter turn handle; turn counter clockwise and pull, then turn quarter turn clockwise until firm5) Bring pump transmission to third gear6) Release clutch, slowly7) listen to pump engage and watch speedometer reading bounce8) Set pump lock levers for third gear9) Dismount and pull tank to pump, engage cooling

10) Tank pump and tank fill are same valve lever on pump panel

Pump Operation

8) Set pump lock levers for third gear

9) Dismount and pull tank to pump, engage cooling

10) Tank pump and tank fill are same valve lever on pump panel

Tank Capacities

Foam

1) A-Foam is 55 gallons2) B-Foam is 220 Gallons

Water

1) 300 Gallon Poly tank

Specifications

1) Diesel: 40 gallon tank (verify)

Basic Starting and Operation

1) Turn key 1/4 to on2) Depress clutch3) Hit either start button (recommended to hit both start buttons)4) Microbrake

Very hard to depress brake peddle enough to release hydraulic brakesCan turn off switch, then depress brake peddle.The brakes are hydraulicReservoir for brakes is under Officer's seat

5) Shifting:Non-syncromesh four-speedShifting pattern is not normal, third gear is up and is pump gearReverse is tricky because of the levers that lock into pump. The upper keeps you from third and reverse: leave down so you don't

end up in reverse by accidentThe lower lever keeps it in third gear when pumping

Pump Panel

Pump Panel from top left to bottom right: This panel was modified by SuperVac

1) Tank and foam level lights; panel heater light that indicates heat tape is activated2) 2 1/2" discharge gauges across top3) Pump overheat light (if pump is overheating this light will illuminate)4) Below gauges are the 2 1/2" drains5) Left side 2 1/2" discharge valves6) Preconnect valve R-side which is plumbed for A-foam7) Preconnect valve L-side is not foam, straight water8) Valve for R-side 2 1/2" discharge9) Tank to pump10) Top valve 2 1/2" intake suction11) Same 2 1/2" suction on L - side12) Compound and pressure gauges; tach, temp, oil pressure13) Prime is below gauge cluster; reservoir is under wood deck behind tank lights14) Throttle below gauge cluster

Trouble shooting: If pump wont prime the PTO cable probably isn't pulled and quarter turn set. Repeat pump engage sequence.

Emergency Lighting

1) Main dash: Quarter turn master switch, this must be on for any electrical to be

usedThis has to be on for any lights to workRadio powerFan defoggerAll accessories

2) On dash is six position toggle for:Emergency lights and spots

3) The VHF and UHF radios are behind seatsUHF is computer programmedVHF is MT500 radio convert-a-com
