FILLING THE SOLUTION TANK
1. The PANTHER 20B can be filled in two
different locations:
a. Front fill area for use with a hose or a
bucket.
b. Rear fill area for use with a hose only.
2. Determine which fill area you would like to
use to fill the machine with water.
3. Fill solution tank with up to 13 gallons of
water. (water temperature should not exceed
140° F) The clear tube in the back left of the
machine has gallon markers to help determine
the water level in the solution tank
: If you are filling the solution tank with a
bucket, make sure the bucket is clean. This will
prevent debris from clogging the lines or solenoid.
: Do not put any flammable materials
into solution tank. This can cause an explosion or
a fire. Only use recommended cleaning chemicals.
Contact your janitorial supply distributor for
recommendations on proper chemicals.
MACHINE OPERATION
: Do not operate machine unless you
have read and understand this manual.
1. Set control housing to a comfortable operating
height by squeezing together the two thumb
levers directly underneath the housing. (see
machine components, item #10)
2. Lower squeegee assembly to the floor by
releasing the lift lever from its locked position.
(see machine components, item #13)
3. Lower brush head assembly to the floor by
stepping on the foot pedal and pushing pedal
forward. (see machine components, item #8)
4. Turn brush motor to “on” position. (see
machine components, item #2)
5. Turn vacuum motor switch to “on” position.
(see machine components, item #1)
6. Turn the solution switch to “on” position. (see
machine components, item #4)
a. Solution will not begin to flow until the
operating triggers are pulled.
7. To begin scrubbing, pull on one or both of the
red operating triggers. (see machine
components, item #23) When these triggers are
pulled, the brush will begin to spin and the
solution will begin to flow.
8. The PANTHER 20B Begin scrubbing by
moving the machine forward.
: Do not keep the machine in the same
position with the pad / brush spinning, or you
could cause damage to the floor.
9. Adjust amount of solution flow by turning the
solution control knob. Turn to the right for
more solution, or turn left for less solution.
(see machine components, item #5)
WHILE OPERATING MACHINE
1. Occasionally look through the clear recovery
tank lid to see if there is any foam build-up. If
excessive foam is found, add defoamer to the
recovery tank.
: Foam must not enter the float shut-off
screen, or damage can occur to the vacuum motor.
Foam will not activate the machines float shut-off
device.
2. Occasionally view the clear tube at the back
left of the machine to check the amount of
cleaning solution that is left in the machine.
3. Occasionally check the battery level meter.
(see machine components, item #3) When
meter is in the red, recharge the batteries.
: When battery meter is in the red, do
not continue to operate the machine. Battery
damage may result.
4. If the squeegee assembly leaves streaks on the
floor, raise the squeegee off the floor and wipe
the blades down with a damp cloth.
: Do not use your fingers to wipe or
remove debris from the blades, as injury may
occur.
5. When the solution tank runs empty, turn off
the brush switch, solution switch and raise the
brush head. Keep the squeegee down and
continue to vacuum until all the dirty water is
picked up. (see TANK DRAINING section to
learn how to drain recovery and solution tanks)
: The brush motor is circuit breaker protected
to protect it from damage. If this breaker trips, it
can’t be reset immediately. You must first
