Extra Notes (Numbers will appear
during scramble)
1. Tank to Pump Valve
2. Hale FOAM Master - Push "On" button to
activate foam at default setting of .5% for a
foam or CAF line.
3. Compressor on-off switch. Must engage-
disengage at idle
4. Pnuemax Auto-Sync Control - Left
Knob-"Fixed" setting is for using the
compressor to run air tools etc, keeps the PSI
from the compressor at a "static" setting.
"Auto" setting allows the compressor to match
water PSI with air PSI, use this when running
CAFS. Right Knob- "Run" setting is required
to activate the compressor along with the on/off
switch. "Unload" is used after compressor
operations are over, bleeds pressure from the
system.

5. Compressor SCFM/LPS-
Indicates the Cubic Feet Per
minute that the compressor puts
out (Also shows metric). The red
arrow on the right side indicates
the SCFM that will produce in the
Auto Sync "Fixed" position.
6. Master Discharge PSI Gauge - Aside from the black needle indicating water psi, you will notice a red needle
which indicates air PSI produced from the compressor. In the "Auto" setting on the Auto-Sync panel, and the
compressor engaged, you can watch the red needle follow the black needle as water pressure increases. Air
pressure will always match water pressure in this setting.
Black-Water & Red-Air PSI
7. Deck Gun Operations - There are 2 valves and 2 guages for deck gun ops. The Grey valve & guage is for water
only deck gun Ops. The Red valve handle and guage are for water/Foam or CAFS. In CAFS mode, the red air
adjustment valve is located to the right of the red valve handle.
8. Booster Reel - The booster reel is capable of plain water or producing a foam solution. IT IS NOT CAPABLE
OF CAFS. There is an air valve for the booster reel which comes from the compressor but it's only purpose is to
assist in draing water out of the booster reel.
9. TPM- "Total Pressure Master" System - Relief valve for the discharge side of the pump and the setting you
choose will also be the pressure setting for incoming water, ie. supply from a hydrant. Excess psi is dumped to the
atmosphere (outside).
Total Pressure Master
10A-10B - 10A is a direct tank fill inlet, 10B is inlet directly into the pump casing. During CAFS operation, use the
Direct Tank Fill inlet for your incoming water supply.
11. Foam Flush - This is a water valve that sends water to the foam
pump for flushing unused or coagulated Class A foam from the
foam pump. The Class A foam never enters the main pump casing,
the flush is only for the foam pump.
To flush- Engage the pump, tank to pump and open the Foam
Flush valve on the pump panel, change the by-pass valve above
the foam pump so the water can flow out of the red rubber hose.
Let it flow until clear, return the valve to it's original position.
Normal Foam operating mode/position. Foam comes from the foam pump up to the valve and to the injectors
Flush mode. Water sent from the Foam flush valve on the pump panel sends water through the foam pump, through the red tubing and onto the ground
TRV - Thermal relief valve - When temperatures inside the pump casing reach 120 degrees, the valve
opens allowing hot water to drain out of the pump and be replaced by cooler water. It is not a
substitute for properly circulating the pumps (Tank/pump-Tank Fill) or assuring a fresh and cooler
water source is available during longer operations. An overheated pump can cause severe damage.
Thermal Relief Valve
W-F-C - These letters on the graphic indicate their capabilty for each 2.5" discharge. W= water only,
no foam or compressed air foam can be used with this discharge. W-F= water and foam solution
capable. Means this discharge can flow water with whatever percent foam solution that comes from the
foam pump. W-F-C= Can flow plain water, water with a foam solution or a combination of water,
compressed air and foam solution (CAFS) CAFS=Compressed Air Foam System
Notes on rear discharges - Both rear 1.5" discharges are CAFS capable. CAFS lines should have a
solid bore nozzle attached. Fog nozzles will break down the bubble structure and quality of CAF.
Deck Gun, Forward/Extended attack with CAF - The deck gun when mounted on top of the apparatus can produce an amazing
amount of Compressed Air Foam. The Deck gun is not limited to using CAF only from it's truck mount. The ground mount,
portable base can be used with the Stinger Deck Gun if the #4 2.5" Discharge (CAFS Capable) is used supply the gun. This
may allow you distance away from the apparatus while applying a massive amount of CAF on a given area, ie. structure already
collapsed or "on the ground" on arrival. Elevation and horizontal control of the Stinger still allows flexibility of application as
well as a minimal water supply problem.
HAPPY PUMPING!
