86447840 Operators Manual - Commodore Duo
19
Normal Scrubbing
Plan the scrubbing pattern in advance.
For efficient operation, the runs should be the longest
possible without turning, stopping, or raising or
lowering scrub deck. The longest track is around the
perimeter of the area to be cleaned and a collapsing
rectangle pattern is most efficient.
In order to achieve the best possible results, the area
which is to be cleaned, should be vacuumed before
scrubbing. Large debris, strings and wire must be
removed to prevent being caught in brushes.
If the machine is allowed to stand in neutral with the
scrub deck down for more than 2 seconds, the
solutions flow stops and brush motor stops. When
forward travel is resumed, the solution flow and the
scrub brush motor will continue. Overlap the brush
path and avoid transporting over previously cleaned
areas.
Recommended Scrubbing Path:
To Begin Scrubbing
When operating the machine around people, pay
close attention for unexpected movement. Use
extra caution around children.
Lorsque vous utilisez la machine en présence de
gens, portez une attention particulière aux mouve-
ments inattendus. Soyez plus prudent, surtout en
présence d’enfants.
1. Turn machine power on.
2. Position rotary switch to the position matching the
process to be preformed, and the chemical that
was added to the solution tank either interim or
extraction/cleaning.
3. Check position of reverse button and the position
speed control knob so that the machine is set to
travel in the direction and the speed intended.
4. Drive machine forward by pressing either throttle
switch to begin scrubbing.
To Stop Scrubbing
1. While scrubbing turn off the pump switch to stop
spraying solution. Continue to scrub and recover
the solution for an additional pass.
2. Allow the throttle switches to return to neutral.
3. Rotate the selector switch to the accessory
position so that the vacuum motor continues to run
and evacuate the system. This will also raise the
deck and vacuum shoes.
4. Turn the rotary switch to the off position by rotating
the selector switch clockwise. Turn machine power
off.
FOR SAFETY: Before leaving or servicing machine:
stop on level surface, turn off machine and remove
key.
FOR SAFETY: When using machine, go slow on
inclines and slippery services.

Batteries (Wet Cell Only)
The batteries provide the power to operate the
machine. The batteries require regular maintenance to
keep them operating at peak efficiency.
The machine batteries will hold their charge for long
periods of time, but they can only be charged a certain
number of times. To get the greatest life from the
batteries, charge them when their charge level reaches
25% of a full charge. Use a hydrometer to check the
charge level.
Do not allow the batteries to remain in a discharged
condition for any length of time. Never expose a

baking soda and water. Do not allow the cleaning
fluid to enter the battery cells, electrolyte will be
neutralized.
2. Maintain the proper electrolyte level in each battery
cell. If a cell should accidentally overflow, clean
immediately.
3. Wipe off the top of the batteries at least once a
week.
4. Test battery condition with a hydrometer at least
once a week.
5. Ensure that all connections are tight and all
corrosion removed.
6. Every 4 to 6 months, remove that batteries from
the machine and clean the battery cases and
battery compartment.
Checking Battery Specific Gravity
Use a hydrometer to check the battery specific gravity.
86447840 Operators Manual - Commodore Duo

NOTE: Do not take readings immediately after adding
distilled water, if the water and acid are not
thoroughly mixed, the reading may not be accurate.
Check the hydrometer readings against this chart.
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80°F (27°C),
the reading must be temperature corrected.
To find the corrected specific gravity reading when the
temperature of the battery electrolyte is other than 80°F
(27°): Add (+) to the specific gravity reading 0.004 (4
points), for each 10°F (6°C) above 80° (27°C).
Subtract (-) from the specific reading 0.004 (4 points),
for each 10°F (6°C) below 80°F (27°C).
