Congratulations and thank you for buying a MASTER-

FORCE™ portable extractor. The MasterForce is designed to
give you truckmount performance in a portable machine that
is versatile to use and easy to transport. Years of experience,
engineering, planning, and practical know-how has gone into
the design and manufacture of the MasterForce. We take a
great deal of pride in MasterForce and want you to be com-
pletely satisfied with your purchase. Please take the time to
read this manual before operating the machine—it will be
time well spent.

SETUP AND OPERATION

ELECTRICAL CONNECTIONS

Plug electrical cords into grounded wall outlets. Master-

Force is designed to run on a 15 AMP and a 20 AMP circuit.
You will normally find 20 AMP separate circuits in the
kitchen and in bathrooms.

Never remove the ground plug

from the end of the cord.

If a circuit breaker trips during

operation, reset the breaker and move electrical cord to dif-
ferent outlet and resume operation. When cords are plugged
into “live” receptacles, the control switches will glow. If the
lights on the switches do not glow, this indicates that the wall
receptacle may be dead. Simply move the cord to a different
outlet. If the power cord is damaged, it must be replaced by a
qualified service person.

WARNING:

The MasterForce is designed for use

with water based cleaning solutions, such as, low
foaming detergents or acid rinses. NEVER USE DRY
SOLVENT SOLUTIONS! The use of dry solvents in
your MasterForce will void the warranty. Not
designed for outdoor use. Children should not be
allowed to play with machine.

AUTOMATIC CHEMICAL FEED

(If Equipped)

Chemical Metering:

The MasterForce may be equipped

with an automatic water fill/chemical feed metering system. As

the solution tank fills
with water, cleaning
concentrate is drawn
into the solution tank at
a designated rate via a
metering tip. A com-
plete set of metering tips
is included.

To adjust the amount

of cleaning concentrate
being drawn, simply
remove the plastic sup-
ply

tube

from

the

chemical feed metering valve (see Figure 1). Unscrew the col-
ored metering tip and replace with the tip that corresponds to
the portable dilution ratio for your cleaning product (refer to
Figure 2). Reconnect the plastic supply tube.

Liquid Concentrates:

MasterForce comes with the purple

metering tip installed at the factory. This tip is rated for .50
oz. of chemical per gallon of water, which is a standard dilu-
tion ratio for the most popular liquid cleaning products on the
market. Refer to your product’s dilution ratio for portable
extractors, and select the proper metering tip from Figure 2
(“Liquid Concentrated Dilution Ratio”).

Powder Concentrates:

For powdered cleaning detergents,

a liquid concentrate must be made. Combine two (2) cups of
powder in a one gallon solution jug. Fill the jug with water up
to the one gallon mark. Use the tip that corresponds to the
portable dilution ratio for your powdered cleaning product
(refer to Figure 2, “Powder Concentrated Dilution Ratio”).

Fresh Water Rinse:

For fresh water rinsing simply leave

the chemical supply tube in the solution tank.

Manual Filling:

To use the MasterForce without the auto-

matic filling system, simply pre-mix your solution in a bucket
of water, and pour into the solution tank. See Figure 3 for a
detailed break-down of the chemical feed system.

Figure 2

Setup:

Inside the solution tank is a bottle float suspended

on a chain. The length of the chain determines the level of
solution in the tank and can be adjusted. Check the chemical
feed supply foot valve for debris, and clean if necessary.
Insert the line into the cleaning concentrate so that it touches
