4. Starting the Spotter - Power Switches:
MA51
The new style MA5 without heat has two switches, one to turn on the vacuum motor & one to turn on the
solution pump.
(Older Power X Pro Spot Extractors without heat only had one switch for both the vacuum and the pump.)
When you are ready to start cleaning, turn the switches to the ON position. For standard cleaning turn on
both switches. For extraction only, you can turn on just the Vacuum Switch. The FloJet solution pump,
standard on the Power X Pro Spot Extractor is self-priming and usually additional priming procedures are not
required.
If the pump does not prime by itself, or if flow is low or unsteady, check the hose from the solution tank to
the pump and the filter screen for clogging, kinks, or restrictions. Clean or replace hose and/or filter and.
Turn switch ON. Check the valve operation and the jet on the tool for flow restriction that can affect
solution flow.
If you are having trouble with the pump, refer to the trouble shooting guide or contact your distributor for
advice or assistance.
MA51H
The MA5 H with heat has three switches one to turn on the vacuum motor, one for the solution pump &
one for the heater.
When you are ready to start cleaning, you should first turn the vacuum switch to the ON position. If you are
extracting only you do not need to turn on the solution pump switch or the heater switch.
If you will be spraying solution, turn the solution pump switch ON. The Flojet solution pump, standard on
the Power X Pro Spot Extractor is self-priming and usually additional priming procedures are not required.
If the pump does not prime by itself, or if flow is low or unsteady, check the hose from the solution tank to
the pump and the filter screen for clogging, kinks, or restrictions. Clean or replace hose and/or filter and.
Turn switch ON. Check the valve operation and the jet on the tool for flow restriction that can affect
solution flow.
If you are having trouble with the pump, refer to the trouble shooting guide or contact your distributor for
advice or assistance.
Once you have solution flow to the tool, you can turn the heater switch ON. Let the heater heat the solution
for about five minutes before you start spraying. For the best heater performance and maximum heat output
use the water slowly and take extra drying passes between spraying passes to give the water more time to heat
up.
5. Spotter Operation:
As you operate the spotter the water and soil you vacuum up will collect in the recovery tank. The Power X
Pro Spot Extractor is equipped with a Float Shutoff assembly which will block the vacuum air flow when the
tank is filled. The float rises with the water level in the recovery tank until it gets to the top, blocking the
vacuum air flow. When this happens you will notice a change in the sound of the vacuum motor. This is your
signal to turn off the unit and empty the recovery tank. Disconnect the hoses and drain the tank by pouring
the water out of the vacuum barb. Do not attempt to drain the recovery tank from the hatch cover opening.
Do not use the same bucket to drain the unit that you use to fill the solution tank. Add more defoamer to the
recovery tank before you resume cleaning.
After draining the tank, before you place the recovery tank back onto the spotter base, check the water level
in the solution tank and add more water and detergent as needed to complete your cleaning. Then place the
recovery tank back onto the solution tank, reconnect the hoses and resume cleaning.

CLEAN VACUUM SHUTOFF ASSEMBLY:
Inside the recovery tank, on top of the stand pipe, is the Vacuum Shutoff Assembly. It functions to prevent
debris and water from being sucked into the vacuum motors. Operating the Power X Pro Spot Extractor
without the Vacuum Shutoff Assembly or with a poorly maintained assembly will greatly decrease the life of
the vacuum motors and will void the warranty.
If debris builds up on this filter, it will reduce the vacuum air flow and may cause a significant decrease in the
rate of water recovery. If debris prevents the float from moving or seating inside the assembly, it may not
stop the airflow when the tank fill with water, and the water will be sucked into the vacuum and blown out
the exhaust. Always use efoamer to prevent foam or moisture from entering vacuums.
To clean:
. Twist to loosen and pull the assembly off of the stand pipe.
2. Pull fibers and lint off and rinse with clean water.
3. Push the assembly back onto the stand pipe and replace the recovery tank lid.
RINSE OUT RECOVERY TANK:
Clean out the tank on a regular basis to extend the life of vacuum & recovery components as well as keep the
tank smelling better.
. Remove the recovery tank lid.
2. Use a hose to rinse the dirt and debris out of the recovery tank.
3. Spray the tank with a deodorizer or disinfectant.
4. Replace the recovery tank lid.
5. Dispose of the dirty water and debris.
FLUSH SOLUTION TANK AND PUMP:
. Pour one gallon of clean water into the solution tank. Slosh the water around in the tank to clean tank
and pour water out and dispose of the dirty water.
2. Pour another gallon of clean water into the tank.
3. With Cord plugged in, connect the solution hose& tool to the solution outlet male quick connect.
4. Direct the tool into a bucket or sink and turn the solution pump ON.
5. Spray the tool into the bucket or sink until most of the water has been pumped out of the solution tank
6. Turn the pump OFF and disconnect the solution hose and tool.
7. Drain the remaining water out of the solution tank and dispose of the dirty water.
If there is a heavy chemical build-up in the machine, hoses, or tools, a mild acid can be added to the rinse
water in the previous procedure.
CLEAN PUMP INLET FILTER
A restricted Pump Inlet Filter can prevent the solution pump from providing adequate pressure for cleaning.
•Remove the stainless steel filter screen and clean as needed.
•Do not operate the machine without the pump inlet filter in place.
•Replace filter, hose & barb as needed.

20
Descaling Heater – MA51H Only:
