run smoothly. This will optimize the airĆtoĆpowder mix and will help to
establish the most efficient working parameters.
If the pump should begin to cycle slowly (bog down), the powder can be
purged by depressing restart button. This will stop the pump and restart
the aeration cycle and allow time to increase air flow to the aeration ports
for proper material movement.
It is good operating practice to dry cycle the pump 5 Ć 10 seconds at the
end of each dispense cycle. This can be accomplished by closing off the
powder source at the suction of the pump or pull wand from material.
This will help clear the pump chambers of any residual powder.
MAINTENANCE
Refer to the part views and descriptions as provided on page 6 through
11 for parts identification and Service Kit information.
S Keep good records of service activity and include pump in prevenĆ
tive maintenance program.
S Certain ARO Smart Parts" are indicated which should be available
for fast repair and reduction of down time.
S Service kits are divided to service two separate diaphragm pump
functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SECĆ
TION is divided further to match typical part MATERIAL OPTIONS.
S Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during service
disassembly and reassembly.
S Before disassembling, empty captured material in the outlet manĆ
ifold by turning the pump upside down to drain material from the
pump.

TROUBLE SHOOTING
S Check for diaphragm rupture.
S Check tightness of (14) diaphragm screw.
S Check (176) check valve for damage or wear.
S Check for restrictions in valve / exhaust.
S Check air supply.
S Check for plugged outlet hose.
S Check for kinked (restrictive) outlet material hose.
S Check for kinked (restrictive) or collapsed inlet material hose.
S Suction hose must be a nonĆcollapsing type, conductive and capaĆ
ble of pulling a high vacuum (up to 30" mercury).
S Check all joints on the inlet manifolds and suction connections. ConĆ
nection must be air tight.
S Inspect the pump for solid objects logged in the diaphragm chamber
or the seat area.
