WARNING: To reduce the risk of fire, electric shock, or injury:
1. You must be trained to operate this machine. This machine is to be operated for its intended use only.
2. Do not operate this machine unless it is completely assembled.
3. Always use a three-wire electrical system connected to the electrical ground. For maximum protection against
electricalshock, usea circuitthat isprotected bya groundfault circuitinterrupter. Consultyour electricalcontrac-
tor.
4. To prevent electric shock, always remove the electrical plug from the electrical outlet before doing any repairs or
maintenanceandwhen leaving themachineunattended.
5. To preventelectric shock, keepthe machine surfacedry. Donot subjecttorain. Store themachine inadry building
area. Clean the machine with a dry cloth only.
6. Machines can cause an explosion when near flammable materials and vapors. Do not use this machine with or
near fuels, grain dust, solvents, thinners, or other flammable materials. Do not use flammables to clean this
machine.
7. Aqualifiedor authorizedperson must domaintenance andrepairs.
8. Topreventdamagetothepowercord,donotmovethismachineoverthepowercord. Alwaysliftthepowercordover
themachine. Donot pullorcarry cord, usecord as ahandle, close adooron cord,orpull cordaroundsharp edges
orcorners. Keep cordaway from heated surfaces.
9. Do notusewith damaged cordor plug. If themachineis notworkingas it should,has been dropped,damaged,left
outdoors,ordropped intowater, return it toa servicecenter.
This machine must be grounded. If it should malfunction or break
down, grounding provides a path of least resistance for electric
currenttoreducetheriskofelectricshock. Thismachineisequipped
with a cord having an equipment-grounding conductor and ground-
ing plug. The plug must be inserted into an appropriate outlet that
is properly installed and grounded in accordance with all local
codes and ordinances.
WARNING - Improper connection of the equipment-grounding con-
ductor 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 machine - if it will not fit the outlet, have a proper outlet installed
by a qualified electrician.
This machine is for use on a nominal 120-volt circuit, and has a
grounded plug that looks like the plug illustrated in figure A. A
temporary adapter that looks like the adapter illustrated in figures B
and C may be used to connect this plug to a 2-pole receptacle as
shown in figure B if a properly grounded outlet is not available.
The temporary adapter should be used only until a properly
grounded outlet (figure A) can be installed by a qualified electri-
cian. The green colored rigid ear, lug, or the like extending from the
adapter must be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the adapter is
used, it must be held in place by a metal screw.
NOTE: In Canada, the use of a temporary adapter is not permitted
by the Canadian Electrical Code
EXTENSIONCORDS
Use only three-wire 12/3 or larger gauge approved extension
cords that have three-prong grounding type plugs and three-pole
receptacles that accept the appliance’s plug. Replace or repair
any damaged cords or plugs.
When servicing, refer to authorized person only. Use only identi-
cal replacement parts.

WARNING! For the safe operation of this machine
follow the instructions given in this booklet and
the training given by your supervisor. Failure to
do so can result in personal injury and/or damage
to machine and property!
DONOTOPERATE MACHINE INANEXPLOSIVE EN-
VIRONMENT!
Themodelsshowninthis manual areintendedforcom-
mercial use.
PREPARATION
Topreparethemachine foroperation,make sureitis of
correct voltage and properly assembled. If in doubt,
askyoursupervisor.
Your new floor machine operates in a straight-line for-
wardmotion,rather than thenormalside tosidemotion
ofa conventional singledisc machine. Beprepared by
having your floor area cleared and ready for the fast
actionof a burnisher.
Preparethefloorareabysweeping,dusting or mopping
as needed. Check the proper application recommen-
dationsandproceduresfoundon the labelofyourfinish
container. IFIN DOUBT,CALLYOUR SUPERVISOR.
WARNING! NEVERUSETHISMACHINEWITHFLAM-
MABLEOREXPLOSIVE MATERIAL!
For Burnishing: Select the correct clean floor pad
(yoursuppliercanhelpyou).The lighter color floorpads
(bufforwhite) arenormallyused fortheburnishing pro-
cedure.
NEVER OPERATE THE MACHINE WITHOUT THE
FLOORPADINSTALLED!
It is very important to select clean, dry pads of uniform
thickness. Pads with high or low sections, or hard or
soft spots are unacceptable. Pads of open weave are
recommended;because closeweaves tend to load up
fast, bog down the machines, cause circuits to over-
loadand generally givepoor results.
Unplugthemachinefromthe wall outletandthentipthe
machine back to expose the pad driver. Remove the
padcenter lock ring. Carefullycenter the padonto the
pad driver and secure with the locking ring. Check for
level,centering and flatness.
OPERATION
Set the machine upright onto the pad. Plug the
machine’spower cableinto aproperly grounded outlet
(see Safety Instructions). Next, release the handle by
unlockingthe knob and allow thehandle tolower into a
comfortable position. THEN ALWAYS SECURE THE
HANDLELOCKINGKNOB. Thiswillallowthe operator
to easily control the pad pressure.
Depressthe handleslightly to elevate the padfrom the
floor. This is toavoid burning theflooron initialstartup,
before the operator is ready to move forward. Pull out
on the “Watch Dog” Safety Lock button and start the
machine by depressing either the left or right switch
levers.
Whenyou’rereadyto move forward, lowerthemachine
headandpadtothefloorandproceedforwardinastraight
line, at a steady pace.
MAINTENANCE
AFTER EACH USE: Store the machine in a clean dry
area. Wipe the entire machine and cord down with a
cleancloth.Removethepadandcleanthoroughly. Wrap
the machine’s electrical cord onto the handles and the
cordhookprovided.CHECKthecordandplugfornicks,
cuts or damage. Report these to your supervisor for
correction.
WARNING! Always disconnect the machine’s elec-
trical plug from the electrical outlet before per-
forming any service, maintenance, pad changing
or inspection of the machine.
MOTOR: The motor is lubricated for life under normal
use. Nooilingorgreasingis necessary. However,if the
machine is used in dusty areas the motor should be
cleaned.Blowing themotor outwith compressedair or
withthe exhaust froma vacuum issuggested. Keeping
the motor clean will allow the clear passage of air for
ventilationandpreventoverheating.
BELT TENSION: Proper belt tension is important for
smooth operation and belt life. Check the belt tension
andhave nomore thana 1/8-inchdeflection. If adjust-
ment is needed, loosen the four (4) motor mounting
bolts. Then move the motor and retighten the four (4)
motormounting bolts.
