OPERATION
What Floor System Works Best With The Charger 2300BP/2500BP .
Dry polishing or burnishing works best with the Charger 2300BP/2500BP. Use mop on restorers rather
than spray buff systems to restore the shine.
Spray buffing is time consuming, uses more pads because they become loaded with floor finish, and
can cause overloading of the machine’s circuit breaker.
HOW THE CHARGER 2300BP/2500BP WORKS
• The Charger 2000BP/2500BP utilizes a 2.5 HP permanent magnet motor to drive the 20" pad.
The pad pressure is adjustable by turning a knob on the top of the machine, which will either
increase or decrease the pad pressure.
•
The level of pad pressure is indicated on the dial on the right-hand side of the control panel. The
pad is adjusted properly when the arrow on average stays in or on the green arrow indicating
proper amps.
• Due to imperfections in the floor, the amps will change slightly. Periodic adjustment may be
necessary to keep the dial running in the green. Too much pad pressure (dial pointing in the
red) may cause the circuit breaker to disconnect the circuit to the motor. If this happens, reduce
the pad pressure, push the black button that says “70” and continue running the machine.
To Begin Operation
Make sure that the correct pad (7/8" to 1") x 20" has been properly installed on the pad driver with pad
grabber and ring in place.
You are now ready to run the machine.
WARNING: MACHINE MUST BE MOVING AT ALL TIMES WHEN PAD IS ROTATING OR
FLOOR MAY BE DAMAGED.
• Turn the master switch to “I”, check the level of battery work range (put machine on “charge” if
not in the high range).
•
Push the machine forward slightly and squeeze the deadman switch lever to activate pad driving
motor. (on VS Model, set knob to desired speed setting prior to operation)
• With the machine moving forward, watch the amp meter for the average needle position on the
meter. Adjust the black knob in the center of the control panel counter clockwise to increase the
pad pressure. It will move the amp indicator needle more toward the right, or the red area.
•
Adjust the knob clockwise to decrease the pad pressure, decreasing the amps which moves the
needle to the left. Adjust until the amp meter needle averages in the area of the green arrow,
indicating proper amps.
WARNING: NEVER OPERATE MACHINE WITH THE NEEDLE IN THE RED AREA OF THE GAUGE,
OR DAMAGE TO THE MACHINE FROM OVERLOAD MAY RESULT.
Floors that have high or low spots will cause the amp meter to enter into the red area occasionally. This
is to be expected and will cause no harm to the machine. If you operate the machine continuously in the
red area, the circuit breaker in the rear panel can, and will blow, indicating too much pad pressure or
load. Push the button to reset, decrease pad pressure by 2 or 3 turns or more on the adjustment knob,
change or turn the pad; otherwise, damage to the machine will result.
Operating the machine with higher than recommended pad pressure in the red area will shorten the
operating time per battery charge. Maximum operating time can be achieved by adjusting pad pressure
throughout the buffing cycle.
Battery Meter Gauge
Turn the switch to the “I” position. Check to see that the indicator light is on. With master switch on ,
check battery meter for charge indication. If needle is in the red area on the left side, marked “recharge”,
the batteries are too low to operate and should be recharged. The middle, green area, indicates
whether or not the batteries are in the high or low range. The right side of the gauge indicates (when the
battery charger is connected and charging and switch is on) the level of the charge in the batteries,
whether high, low or in between. When needle is in the far right, red area, shown as high, and the
automatic charger has shut off, charging of the batteries is complete.
