Maintenance
Pump
The pump is located on underside of the recovery tank.
The pump delivers solution from the tank to the scrub
deck.
To repair or replace pump:
1. Remove bracket assembly from the bottom side of
the recovery tank.
2. Remove hoses connecting the pump.
3. Remove screws that secures pump to mounting
plate.
Solution Strainer
The solution strainer is located under the recovery tank.
The strainer protects the pump, solenoid valve and jets
from debris. If there is little or no solution flow to the
ground, check the strainer for debris. Clean the solution
strainer. To remove the strainer, turn the bottom part of
the strainer counterclockwise until the bottom is sepa-
rated. Clean out the debris from the wire mesh and the
bowl and re-assemble. Make sure the O-ring gasket is
in place when re-assembled.
Solenoid Valve
The solenoid valves is mounted on the front of the
scrub deck, on left side.
The solenoid valves shuts off solution flow to jets
whenever scrubbing stops or in reverse. To repair or
replace solenoid valve, remove screws that secure it to
deck.
Jets
The two sets of jets are located in front of the scrub
deck.
The jets spray cleaning solution onto the carpet. The
spray pattern should be checked regularly and if jets
become clogged they should be cleaned or replaced
immediately.
To clean jets:
1. Remove jet from jet body by rotating it counter-
clockwise.
2. Blow debris back through orifice if possible. Do not
use pointed object to unplug jet. This will damage
jet and cause improper spray pattern and solution
flow through jets.
3. If jet cannot be cleaned by blowing debris back
through its orifice, submerge jet in small container
of acetic acid and let soak for up to six hours.
4. After soaking jet, use a soft brush to remove debris
and rinse thoroughly.
5. Install jet in jet body by rotating it clockwise firmly
into place.
6. For lower flow in extraction "B" other jets are avail-
able. (See Accessories page).
