Double Scrubbing
 This procedure provides deeper cleaning on heavily
soiled floors. One or more cleaning passes are made
before picking up the chemicals with the squeegee.
This allows dwell time. Best results are achieved by
placing the brush motors in the heavy scrub position.
Caution: The floor surface becomes extremely slippery
in this operation. This machine should be operated only
in slow to medium speed and great care should be
taken when walking on this wet surface.
Stripping
 This procedure is used to remove moderate build-up
of floor finish from the floor. The most aggressive
pads or grit brushes are used in this procedure.
 The stripper solution is applied to the floor with a mop
and then double scrubbed as above. Stripping
solution should not be put into the solution tank.
Clean water from the solution tank is applied to the
floor to keep the chemicals and finish in a "liquid"
condition. The floor surface becomes extremely
slippery in this operation. This machine should be
operated only in slow to medium speed and great
care should be taken when walking on this wet
surface.
 If equipped, the scrubber may be used to apply the
wax stripper using the Sidekick Chemical dispenser.
Set the dilution ratio to the rate recommended by the
chemical manufacturer. If the wax stripper you are
using requires dilutions stronger than 20:1, then you
will need to apply the stripper with a mop.
 After applying the stripper, thoroughly purge the
Sidekick Chemical dispenser lines with clean water to
remove all traces of wax stripper. Purge the lines
while the scrub brushes are positioned over a floor
drain. Purging the Sidekick's lines will dispense
chemical thru the scrub pads and onto the floor.
Sidekick Chemical Dispenser Operation
***CAUTION: Purging the Sidekick lines may
dispense a small amount of the chemical directly
onto the floor. If using wax stripper or harsh
chemicals, be sure to purge the lines in an area
that cannot be damaged by the chemical in use,
such as over a floor drain.
See Preparing the Machine for instructions on how to
connect the chemical bottle, and purge the lines.
After proper connection of the chemical supply line and
purging, the Sidekick Chemical Dispenser provides fully
automatic chemical dilution during scrubbing
operations. The Sidekick measures the amount of
water flowing out of the solution tank, and pumps the
correct amount of chemical into the water line to provide
the ratio of water to chemical according to the dilution
ratio selected on the control panel.
The pump will not operate unless water is flowing from
the solution tank (except when the purge button is
pressed). This means the Solution Control valve must
be on, and the brushes must be spinning.
Basic Operation
 Turn on the Scrubber.
 Turn on the Sidekick Chemical Dispenser.
 Select the desired dilution ratio by pressing the Select
Dilution button until the light next to the desired ratio
is illuminated.
 The scrubber can be turned off, and when the
scrubber is turned back on, the Sidekick will recall the
last dilution setting.
 During use, the Purge button may be pressed to
provide and extra dose of chemical for heavily soiled
areas (always follow chemical manufacturer's usage
directions).
To Change Chemicals
 Loosen the cap on the chemical bottle, and remove
the suction line from the chemical bottle.
 Dispose or store any remaining chemical according to
local and federal regulations.
 Place the suction line into a container of clean water.
 With the machine over a floor drain, press and hold
the purge button until the clean water is drawn thru
the pump and dispensed at the brushes.
 Remove the suction line from the container of clean
water. Replace the container of clean water with a
container of the desired chemical, and install the
suction line.
 Press and hold the Purge button until chemical is
seen being drawn up to the pump, and pumping down
the tube from the pump to the tee fitting below the
machine.
 After each use, always flush the Sidekick lines
with clean water to prevent dried chemical from
accumulating in the lines.

MACHINE MAINTENANCE

Routine maintenance is critical to ensure proper
machine operation and cleaning performance. Perform
all maintenance procedures as follows.
Always turn OFF all machine switches (except the
EMERGENCY STOP) before performing any
maintenance.
Adjusting the Squeegee Assembly:
 Turn the vacuum motor ON and open the water valve
slightly.
 Squeegee blades should lie over slightly (like a
window squeegee) when the machine is moving.
 If adjustment is required adjust the blade angle by
removing the rear bolt of the top squeegee arm, turn
the arm into or out of the ball joint to change the angle
as needed.
Adjust Side Skirt Wiper Blades:
 Install the side skirts on the machine.
 Loosen the retaining strip screws.
 Pull down evenly on the entire length of the wiper
blade so that it firmly touches the floor.
