In the Field
Watch out for the wing nut on the
drain valve when you load and trans-
port the pump. The nut can be easily
damaged if something is banged
against it. Then you can't fill the
pump. Give the nut extra protection
for transport by taping bubble wrap
or something similar over it.
Be careful connecting the hoses. If you
crossthread a hose, it leaks and you'll have
trouble building up pressure. Crossthreading
can also damage the hose gasket. If the hose
is screwed on correctly, the locking ring
should turn easily. If it doesn't, take the hose
off and try again.
Once you have the hose connected right,
tighten the locking ring hand-tight and then
use the spanner wrench to give the ring 1/2
turn more. Stop there. Any tighter can dam-
age the hose gasket.

M17-Series Decon,
M12A1 Decon.…
T
he 65-gpm pump used with the M17 and M12 decons is the little helper that gen-
erally does its job without much attention from you. But if it stops pumping, you
soon stop deconning. Here are some secrets for keeping the pump pumped up.
In the Motorpool
Before you go to the field, make sure
both the inlet and outlet hose connector
gaskets are in place and in good shape.
If a gasket is missing or cracked, you
can't build up water pressure for pump-
ing. Order new gaskets with PN
13230E5325 from Schleyer Pump,
(765) 643-3334.
After you drain the pump housing,
tighten the wing nut hand-tight only.
Forcing the nut tighter can damage it
and make draining difficult later.

Remember, never run salt water through the pump. Salt corrodes the engine and
locks up the pump.
