OPERATION OF THE DUAL SPEED
MACHINES
Follow the operation procedures described for 175 RPM machines.
The proper speed selection is important to properly operate these
machines. Speed selection Low (175 RPM) or High (320 RPM) is
made with the switch located on the base and motor housing.
(See Picture #4)
Stripping, scrubbing, bonnet cleaning and
shampooing should be performed at 175 RPM Low Speed. Spray
buffing and dry buffing should be performed at 320 RPM, High
Speed. Spray cleaning is a two speed maintenance operation.
Apply a spray buff chemical to the floor ahead of the machine.
Make the first passes through the spray buff at low speed with an
open weave blue cleaner pad or the brown hoghair blend spray
cleaner pad. Remove the spray cleaning pad and place a buffing
pad on the machine, yellow, beige or natural hoghair blend pads.
Switch the speed to High 320 RPM and buff the dulled finish to
a high gloss. Unplug the power cord and wrap it under the cord
hook and over the right handle grip. Clean the cord off to prevent
heavy soiling and cleaning residues from building up on the cord.
This is a good time to inspect the cord for cuts, gashes and loose
prongs. Tip the machine back and remove the pad and the drive
block or brush. The condition of the floor pad or brush has a direct
affect on the performance of your floor machine. When the pad
becomes dirty, turn it over and use the other side. When finished,
wash the pad or brush and allow it to dry completely before using
it again. Stand the wet brush on the bristles until dry, then hang up
the brush.
Do not store the machine with the drive block, pad or brush on the
machine.
Wipe off the machine housing and wheels to prevent build-up of
unnecessary residue.
TRANSPORTING THE MACHINE
Place the handle in the upright position. Lock the handle cam release
lever. Tip the machine back and transport on the wheels.
MAINTENANCE
For 97598 and 97599 only:
The length of the carbon brushes
should be inspected annually. If they are no longer extended
past the holder window, they should be replaced. Replacement
of the carbon brushes should only be done by a qualified
service technician.
TROUBLESHOOTING
Machine does not run.
The circuit breaker has tripped. Allow the circuit breaker 2 min-
utes to cool before resetting. Plug is broken or has loose con-
tact. Replace.
Prevent circuit overload.
Check the pad and change it if it is rough or dirty. Spray buffing
or spray cleaning is not a substitute for scrubbing or mopping a
floor. Prepare the floor surface before spray buffing. Eliminate
any extension cord that is smaller than 12/3 wire or greater than
25 feet in length. Unplug anything other than the machine from
the circuit or locate another circuit.
Machine will not start.
Circuit breaker is not reset. Reset breaker.
Plug is broken or has a loose contact. Replace.
Circuit breaker is defective or weak. Replace.
Switch is defective. Replace switch.
Machine will not reach operating speed.
Unplug anything else other than the machine from the circuit or
locate another circuit.
Motor runs but pad or brush does not turn.
Coupling is broken. Replace. Coupling is not covered under war-
ranty. Do not attempt to place a running machine over a block or
brush. Always place and remove the block or brush by hand.
SAFETY INSTRUCTIONS
This Floor Machine should be grounded while in use to protect
the operator from electric shock. This machine is equipped with
a 3-conductor cord and a 3-prong grounded type attachment cap
plug to fit the proper grounding type receptacle. The green (or
green and yellow) conductor in the cord is the grounding wire.
Never connect this wire to anything other than the grounding
blade. The Floor Machine is provided with an attachment cap
plug, as shown in Sketch A, and is intended for use on a nominal
120 volt circuit. If a properly grounded receptacle, as shown in
Sketch A, is unavailable, an adaptor, as shown in Sketch C, is
available and should be installed, as shown in Sketch B, if the
outlet box that houses the receptacle is grounded. Be sure to fas-
ten the grounding tap to the faceplate screw.
*This applies only to North America. The 230v model is designed
to operate on a 230/50 Hz electrical connection. Make sure the
electrical outlet is grounded and all safety precautions are taken.
