Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
1. Turn the flow adjustment knob (H) counterclockwise
until it stops.
2. Turn the motor power switch (S) off.
3. Hold the hose firmly against a pail.
4. If the ball valve kit (17J703) has been installed,
open the ball valve.
5. If you suspect the hose is completely clogged, or
that pressure has not been fully relieved after
following the previous steps, slowly open the fluid
drain/purge valve (C) at the pump outlet and drain
material into a waste pail.
Clearing a Clogged Hose
1. Follow the
2. If you suspect there is a clog in the hose, disconnect
the hose at the connection farthest from the pump.
Continue to disconnect the hose back toward the
pump (upstream) until the hose with the clog is
reached.
3. To clear a clogged hose:
a. Disconnect the clogged hose from the pump if
not done already.
b. Use a rope or a strap to secure the clogged
hose to a permanent, stationary column.
c. Use a water hose to clear the clogged or dried
material from the material hose. Do not use a
hammer on the hose, or insert any potential
projectiles (such as sticks, rebar, etc) into the
hose end.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid and moving
parts, follow the Pressure Relief Procedure when you
stop spraying and before cleaning, checking, or
servicing the equipment.
To avoid injury from splashing fluid, never open a
cam-lock hose or applicator fitting while there is
pressure in the fluid line.

NOTICE
