FLUSH SOLUTION TANK AND PUMP: (continued from previous page)
•
Disconnect the solution hose and tool.
•
Use the vacuum hose to vacuum the remaining acid solution out of the solution tank.
•
Pour two or three gallons of clean water into the solution tank.
•
Connect a solution hose to the solution outlet female quick connect. The other end of the hose
should have an open quick connect or no quick connect to allow full flow out of the hose.
•
Direct the open end of the solution hose into the recovery tank vacuum barb.
•
Turn one or both of the vacuums ON and turn the solution pump ON. Let the pump run until most
of the water has been pumped out of the solution tank.
Do not let the pump run dry. Turn the
pump OFF before the water gets to the bottom of the tank.
•
Turn the vacuums OFF and disconnect the open flow solution hose.
•
Place a bucket under the drain valve and open the drain valve to drain the water out of the recovery
tank.
•
Close the drain valve and dispose of the water.
CLEAN PUMP INLET FILTER
A restricted Pump Inlet Filter can prevent the solution pump from providing adequate pressure for cleaning.
A restriction or air leak on the pump inlet hose can also
damage the solution pump check valves and plunger seals.
•
To examine the filter, open the solution tank lid on
the front of the machine. The filter is in the bottom
of the solution tank.
•
Grasp the filter cap and unscrew the filter from the
brass nipple by turning counter-clockwise. Clean or
replace the filter as needed (PP14-806504).
Before proceeding with this procedure,
drain the solution tank & recovery tank. Make sure
both power cords are disconnected.
•
To examine the pump inlet hose, release the latches on the front/bottom of the machine and tilt the
tanks off of the base assembly.
•
Examine the hose for kinks, clogs or holes and repair or replace the hose as needed.
(Replacement Hose: NM5086 – sold per foot)
•
Tilt the tanks back onto the base and secure the latches.
