INSPECTION
Please carefully unpack and inspect your
GROUTHOG for shipping damage. Each unit is
operated and thorougly inspected before shipment,
and any damaged is the responsibliltiy of the
delivering carrier who should be notified immediately.
ELECTRICAL
The Grouthog is designed to operate on a standard
15 amp, 115 volt, 60 hz, AC household current.
Check that the voltage shown on the serial number
plate is suitable for the supply available. Voltages
below 105 volts or above 125 volts could cause
damage to the motor.
* 230/250 volt 50 hz models are available.
NOTE: The GROUTHOG is equipped with a safety
relay switching system that prevents accidental motor
start-up. If the power cord is unplugged during use,
the machine will not start when reconnected, until the
the ‘ON’ switch is depressed.
GROUNDING INSTRUCTIONS
This applicance must be grounded. If it should
malfunction or break down, grounding provides a
path of least resistance for electric current to reduce
the risk of electric shock. This appliance is equipped
with a cord having an equipment-grounding
conductor and grounding plug. The plug must be
inserted into an appropriate outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Improper connection of
the equipment-
grounding conductor can result in a risk of
electric shock. Check with a qualified electrician
or service person if you are in doubt as to
whether the outlet is properly grounded. Do not
modify the plug provided with the appliance. If it
will not fit the outlet, have a proper outlet
installed by a qualified electrician.
This appliance is for use on a nominal 120-volt
circuit, and has a grounded plug that looks like the
plug in “Fig. A” below. A temporary adaptor that
looks like the adaptor in “Fig. C” below may be used
to connect this plug to a 2-pole receptacle as shown
in “Fig. B” below, if properly grounded outlet is not
available. The temporay adaptor should be used
only until a properly grounded outlet (Fig. A) can be
installed by a qualified electrician. The green colored
rigid ear, lug, or the like extending from the adaptor
must be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the
adaptor is used, it must be held in place by a metal
screw.
To avoid electrical
shock, use indoors only.
EXTENSION CORDS
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine and should be limited to 50 feet in length.
Extension cord must be three wire grounded. The
machine is equipped with a 18/3-40’ power cord.
EQUIPMENT SETUP
NOTE: Attach stain relief/cord retainer to the power
cord.
1. Make a loop in power cord
approximately 18” from main
housing.
2. Slide cord loop through slot in
retainer arm. Pull slack cord
back though slot to secure.

OPERATION

SELECT THE RIGHT CHEMICAL FOR THE JOB:
1. For greasy or oily soil – Use a heavy-duty
degreaser.
2. For sealer or old wax - Use a heavy-duty
stripper.
3. For soap residue and lime build-up – Use a mild
acidic cleaner.
4. For routine maintenance – Use an all-purpose
cleaner.
Consult your Windsor
dealer for proper
chemicals. Always follow directions on the
container of the chemical being used.
SELECT THE RIGHT BRUSH FOR THE JOB:
1. For routine maintenance use the Universal
STANDARD Brush.
2. For cleaning groutlines use the Universal
AGRESSOR Brush.
CLEANING PROCEDURE
1. Remove trash receptacles, etc., from the area to
be cleaned.
2. Sweep or dust mop the floor.
3. Remove gum, labels or other debris from the
surface with a scraper.
4. Apply the pre-mixed solution generously with a
wet mop (or use optional tank) to a section of the
floor. Let solution stand for 5 to 10 minutes. Do
not allow solution to dry on the floor.
5. Plug the power cord of the machine into a
properly grounded outlet.
6. Adjust handle to a comfortable height.
7. Depress the “ON” switch to start machine.
(Depress the “OFF” switch to stop machine.)
The brush-drive motor is
thermally protected and
should an overload condition occur causing the
motor to stop, the machine will not start until the
“ON” switch is depressed.
8. Start cleaning at the farthest corner and work
toward the door. For best results, pull machine
backwards at a steady pace.
9. Keep the machine moving to avoid possible
damage to the grout.
10. Use a bristle hand brush to clean inside corners
and small areas not accessible by machine.
11. After scrubbing, rinse floor with clean water. Use
a wet vacuum to pick up loosened dirt an
solution.
12. Groutlines will appear dark at first, but will lighten
after they dry.

MAINTENANCE
GROUTHOG 86038000 05/17/07 5
Do not overheat block as
this will damage the bearing.
DAILY MAINTENANCE
1. Before storing the machine, clean exterior.
Remove brush and rinse clean with hot water.
2. Periodically inspect electrical cable and
connections. Because the cable will lie on wet,
abrasive floors, the cable must be well insulated.
If the insulation is broken or frayed, repair or
replace immediately.
3. Remove wheels periodically and apply silicone
lubricant to the axle.
SERVICING THE GROUTHOG
Always disconnect the
power cord from electrical
source before making repairs or adjustments.
BRUSH REMOVAL
1. Place handle in upright position. Tilt machine
back with handle resting on floor.
2. Loosen Knob Assembly (item 20) holding the left
bearing block (item 29).
3. Remove bearing block from the frame and brush
core.
4. Remove brush (item 33) from the right bearing
block (item 38). When re-installing the brush,
make sure that the guide pins (item 30) on both
ends are properly aligned with the holes in the
brush core and the bearing block (items 29) is
correctly seated.
BELT REPLACEMENT
1. Remove main cover (item 73 held on by (4)
screws). Remove bottom belt guard (item 34
held on by (2) screws).
2. Using an allen wrench, remove the screw holding
the right bearing block (item 56).
3. Remove bearing block along with the old belt.
Replace belt and bearing block. Check belt for
proper tension and alignment (see Motor
Replacement for belt adjustment).
BEARING REPLACEMENT
Using a small torch, heat the aluminum bearing block
just enough to allow the bearing and shaft (items 31
and 32, respectively) to be removed.
Use a bearing puller to remove old bearing. When
replacing bearing, use a socket or metal sleeve just
large enough to slip over the shaft and still contact
the inner bearing race. Use an arbor press or vise to
press new bearings on shaft. Re-heat aluminum
block just enough to allow re-assembly of bearing
and shaft.
MOTOR REPLACEMENT
1. Remove motor cover (item 73 held on by (4)
screws).
2. Remove (4) screws holding motor (item 60).
Disconnect motor lead and remove motor.
3. When re-installing the motor use a straight edge
to realign pulleys. A screw driver can be used to
adjust tension.
4. NOTE: Belt should be adjusted to snug fit to
prevent slipping. DO NOT OVERTIGHTEN.
