that a slurry nozzle is on each of the gun assemblies at the ends of the discharge hoses. See that the two
fire hose foam nozzles and two fire hose water nozzles are in the toolbox.
Inspect the suction and blender hoses and the two discharge hoses for breaks, cuts, or damage that would
result in leaks.
Suction and Blender Hoses. See that gaskets are on the connector ends of the hoses. Check that each
connector is complete and in good condition. See that the foot valve assembly is undamaged and is
clean. Inspect for enlarged holes that would allow large pieces of foreign matter to be drawn into the
M12A1 PDDA. See that the four bracket clamps that fasten the suction hose (with the blender hose
inside) are in place on top of the tank unit assembly. See that the exhaust pipe extensions are coiled next
to the suction hose and are fastened by criss-crossed lashing. Fasten lashing through the bracket clamps.
Discharge Hoses. See that gaskets are in place and are not damaged. See that couplings are complete
and all threads are clean and free of nicks and burns. Make sure that the two hose reels are in good
condition and that the crank handle is in the toolbox.
To inspect the drive belts and the generator belt, remove the lower right and lower left front panels of
the pump unit. Inspect the belts for breaks, and for worn or frayed edges. Inspect the belts for proper
tension using the V-belt tensiometer shown in Figure 14. If the belts are too loose or too tight, you will
need to adjust them.
Figure 14. Tensiometer.
Drive Belts. To adjust the drive belts, use the following steps.
Step 1. Remove the tensiometer from the toolbox and check to see that it is clean and serviceable.
