INSPECTION:
Carefully unpack and inspect your 879 for shipping damage. Each machine is tested and inspected
before shipping. Any shipping damage incurred is the responsibility of the carrier. You should notify the
carrier immediately if you notice damage to the box, the machine, or its parts.
CLEANING SOLUTIONS:
We recommend liquid cleaning chemicals. Powder chemicals may be used, but unless mixed very thoroughly
they could cause a build-up in the pump, lines, and quick disconnects. Any problem caused by a chemical
build-up is not covered by warranty. Use a neutral cleaner with a pH between 5 and 10 to avoid premature
wear of the pump, seals, and/or other components. It is a good idea to test an inconspicuous area of
the floor.
MAINTENANCE:
For optimum performance flush the machine with clear water at the end of each working day. Once a
month, minimum, run a flushing compound through the machine to break up any mineral or chemical build-
up that may have formed. The vacuum motor and the pump do not require any scheduled maintenance;
however, the motor may require replacement brushes after 1000 - 1500 hours. Clean the body with an
all-purpose detergent, and protect it with an automobile interior polish. Lubricate the wheels, castors,
and quick disconnects with an all purpose silicone spray.
PARTS AND SERVICE:
Repairs, when required, should be performed by your Servpro distributor who maintains an inventory of
original replacement parts and accessories. Call the distributor from whom you purchased this machine if
you need parts and service. Be sure to specify the machine model. Have your serial number handy.
DANGER: DO NOT USE SOLVENTS, OR ANY CHEMICALS
THAT MAY BE FLAMMABLE, EXPLOSIVE, OR COMBUSTIBLE.

SET-UP & OPERATION
1. Before each use, inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
Make sure hoses are in good condition and the spray nozzle(s) is tight.
2. If not using the auto-dump feature, just make sure the brass cap is on the drain hose connector on the
front of the base of the machine.
If you choose to use the auto-dump feature, remove the brass cover on the hose connector on the
front of base of the machine, attach a hose, and place the open end of the hose in a drain. Make sure
the recovery tank drain gate is closed, and the lid is tight on the recovery tank.
3. If you choose not to use the auto-fill feature, just fill the tank with water and cleaning
chemical. Follow chemical directions regarding dilution and mixing. Do not use harsh chemicals; they
may damage seals in pumps and valves, and cause the pump to wear prematurely. .
If you choose to use the auto-fill feature, connect the fill hose to the auto-fill connector (located over
the solution tank fill hole). Turn on the water source -- HIGH PRESSURE IS NOT NECESSARY -- and
allow the tank to fill with water. When using the auto-fill system, the auto-fill float will automatically
turn on and turn off as the tank empties and then fills.
NOTE: Never put water with a temperature exceeding 130 °F / 54 °C in the solution tank
4. Pre-spray the area to be cleaned, with a pump-up sprayer, while the tank is filling. Follow chemical
directions.
5. Plug in the two power cords. Do not connect both cords to the same outlet. The green, ‘separate
circuit locator light (1) on the switch plate should light up. If the locator light does not come on,
check the circuit breaker box in the wall, and/or try different outlets until it does turn on. Although all
systems in the machine may work correctly if you are not on two circuits, a circuit breaker in a wall
panel may trip. If you make sure the green light is turned on, you will prevent tripped circuit breakers.
6. Prime the 1200 psi pump: fill the solution tank with water, if not already done, and turn on the pump.
You may notice a ‘tone’ change in the sound of the pump (smoother, with less of a rattle).
CAUTION -- NEVER TURN ON THE SOLUTION PUMP BEFORE CONNECTING YOUR
SOLUTION LINE TO YOUR MACHINE AND TO YOUR TOOL. If the pump builds pressure
before you connect the hose and tool, you will not be able to connect them.
7. Use defoamer to prevent foam.
8. Attach the solution spray hose to the solution quick disconnect. Attach the vacuum hose to the hose
barb on the front of the recovery tank. Connect the other ends of the hoses to the tool.
9. Turn on the vacuum (2) and turn on the dump pump (3). Begin spraying.
10. When the job is finished, turn off the water source. Vacuum the remaining solution from the solution
tank into the recovery tank.
11. Run a few gallons of clean water through the system. Drain the recovery tank by opening the drain
gate over a bucket or drain. Disconnect the hoses from the cleaning tool.
12. Unplug the power cords.
13. Clean the machine and the tool. Never store your machine outside, and keep it from extremes in tem-
peratures.
NOTE: if the green, circuit locator light does not illuminate when the cords are plugged in, then both cords
are on
the same circuit. Try other outlets with one of the cords until you get the locator light to come on.
NOTE: if the heat switch is turned on when both cords are on the same circuit, the breaker in the wall may
trip.

1 Operation:
•Attach a 3/4” garden hose to the auto-fill valve, and connect the other end of the hose to your water
source.
• Make sure the float that hangs from the auto-fill valve into the tank is free of obstruction and can
move freely.
• Turn the water supply on.
• The auto-fill float will automatically shut-off the flow of incoming water when the solution tank is
nearly full, and it will allow the valve to open again once the water level has dropped to a predeter
mined level.
AUTO-FILL
1 Operation:
•Before each use: if necessary, unscrew the stainless steel filter at the bottom of the recovery
tank and clean it. Also make sure the float in the recovery tank is clean.
•Attach a 3/4” garden hose to the dump pump outlet fitting on the back of the base of the
machine.
•Run the other end of the hose into a drain.
•Turn ON the dump pump switch (switch is located on the switch panel on the top of the machine).
•NOTE: the dump pump is ‘self-priming.’ You should see water start to flow within 30 seconds of
the pump turning on. If water does not begin to flow, check the filter to see if it is plugged with
debris.
•After each job: run clear water though the dump pump to wash out any chemical residue.
Remove and clean the stainless steel filter in the back of the tank. Reinstall the filter once it is
clean. Clean and empty the recovery tank.
AUTO-DUMP
CAUTION: Use care when handling hazardous chemicals.
CAUTION: Never leave the machine running when you are not actively using it.
CAUTION: always use a defoamer in the recovery tank to prevent water or foam
from entering the vacuum motor.
CAUTION: Always make sure the float cage is clean and the ball can
travel freely before turning on the machine.
AUTO VACUUM SHUTOFF:
When the recovery tank is full, the ball float will shut-off the suction to prevent the machine from
overflowing. NOTE: the float may not work if there is foam in the tank. Always use defoamer to
prevent overflow.
