HOW TO PREPARE THE MACHINE FOR
OPERATION
The Image 26B uses three 12-Volt batteries. The
batteries are located on a battery tray that can be
accessed by opening the front cover and lowering the
frontbridge. Toinstallthebatteries,followthisprocedure:
1. Turnkeyswitch off.
2. Make sure both tanks are empty.
3. Placethebatteriesinthebatterytrayasshownin

WARNING: Liftingbatterieswithouthelpcould
result in an injury. Get help to lift
the batteries. The batteries are
heavy.
WARNING: Working with batteries can be
dangerous. Always wear eye
protectionandprotectiveclothing
when working near batteries. NO
SMOKING!
4. Connectthebatterycablesbetweenbatteriesand
install long battery cable assembly as indicated.

Battery Maintenance
Theelectricalpowertooperatethemachinecomesfrom
thestoragebatteries. Storagebatteriesneedpreventative
maintenance.
Tomaintainthebatteriesingoodcondition,followthese
instructions:
1. Keep the electrolyte at the correct level. The
correctlevelisbetween1/4"belowthebottomof
the tube in each cell and above the tops of the
plates. Check the level of the electrolyte each
time you charge the batteries. See figure 12.
NOTE: Checkthelevelofelectrolyteprior tocharging
thebatteries. Besuretheplatesineachcell
arecoveredwithelectrolyte. Do not topoff
the cells prior to charging the battery.
Electrolyte expands during charging. As a
result,theelectrolytecouldoverflowformthe
cells. Always top off the cells with distilled
wateraftercharging.

Clarke®Operator's Manual IMAGE 26B Page -11-
HOW TO PREPARE THE MACHINE FOR
OPERATION
CAUTION: Irreversible damage will occur to
the batteries if the electrolyte
level does not cover the plates.
Keep the electrolyte at the
correct level.
CAUTION: Machine damage and discharge
across the tops of the batteries
can occur if the batteries are
filled above the bottom of the
tube in each cell. Do not fill the
batteries up to the bottom of the
tube in each cell. Wipe any acid
from the machine or the tops of
the batteries. Never add acid to
a battery after installation.
CAUTION: Tap water may contain contami-
nants that will damage batteries.
Batteries must be re-filled with
distilled water only.
2. Keep the tops of the batteries clean and dry.
Keep the terminals and connectors clean. To
clean the top of the batteries, use a damp cloth
with a weak solution. To clean the terminals
andconnectors,usea terminal and connector
cleaning tool. Do not allow ammonia or bicar-
bonate of soda to get into batteries.
3. Keepthebatteriescharged.
How to Charge the Batteries
WARNING: Charging the batteries in an area
without adequate ventilation
could result in an explosion. To
prevent an explosion, charge the
batteries only in an area with
good ventilation.
WARNING: Lead acid batteries generate
gases which could explode.
Keep sparks and flames away
from batteries. NO SMOKING!
WARNING: Failure to disconnect the AC
plug from the wall receptacle
before connecting or disconnect-
ing the DC connector on the
charger could result in an
explosion. Always disconnect
the AC plug from the wall recep-
tacle before connecting or
disconnectingtheDCconnector
on the charger.

4. Turn the key switch to the "ON" position.
5. Press either of the traverse switches to activate
spray.
6. Allowthesolutiontorunthroughthemachineover
the floor drain until the solution tank is empty.
CAUTION: Cleaning solution in the
machine and tools can leak
onto the carpet and cause
light spots or stains. Do not
leave the extractor or other
cleaning machines or tools
on the carpet when not in
use.
Tochargethebatteries,followthisprocedure:
1. Put the charger on a flat surface. Make sure
the vents on the side are at least two inches
away from walls and other objects. Make sure
there are no objects near the vents on the
bottom of the charger.
2. Make sure the key switch is in the "OFF"
position.
3. Disconnect the battery pack connector from the
control housing connector. See figure 13, A.
4. Connect the DC connector on the charger to the
battery pack connector. See figure 14.
5. Connectthechargertoaproperlygrounded
singlephase(3-wire)wallreceptaclehavingthe
voltage,frequency,andamperecapacity
specifiedonthenameplateofthecharger.
For more instruction on the use of the charger, read
the instruction book supplied with the charger.
DANGER: Failure to read the operator’s
manual before operating this
machine could result in injury to
you or to other personnel,
damage to the machine or to
other property as well.
CAUTION: The antifreeze solution that is
shipped in your machine will
damage carpet. Flush the
antifreeze solution from the
system before using the machine.
Your new machine has been shipped with antifreeze
solution in the machine's system. This antifreeze must
be flushed out prior to using the machine the first time.

CAUTION: Pump damage can occur if the
pump is operated without water in
the solution tank. Do not activate
the pump if the solution tank is
empty.
1. Put water and cleaning solution into the solution
tank. Clarke recommends using Clarkare®
ExtractorConcentrate asacleaningsolution. For
everygallonofwater,add betweentwoand ten
ouncesof Clarkare®. Theamountofcleaning
solutionused dependsontheconditionof thecarpet.
DANGER: Electrocution could occur if
machine is connected to an
electrical outlet that is not properly
wired or grounded. Always use a
3-wire electrical system connected
to electrical ground. For maximum
protection, use a circuit that is
protected by a ground fault circuit
interrupter (GFCI). Consult your
electrical contractor.
2. Make sure battery pack is plugged into machine.
