WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and
open flame away. Keep battery compartment open
when charging.
FOR SAFETY: When servicing machine, wear
protective gloves when handling batteries or
battery cables. Avoid contact with battery acid.
INSTALLING PAD

operate over 2000 RPM. The pad should be a
maximum of 25.4 mm (1 inch) thick,
483 mm (19 inch) in diameter with a standard
89 mm (3.5 inch) center hole.
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.
2. Tap the right front side of the pad shroud with your
toe. The head will rise to the pad mounting
position (Figure 2).
FIG. 2
3. Remove the plastic centerlock from the pad driver
by turning it clockwise. Position the pad accurately
centered on the pad driver, and screw the
centerlock in place counter-clockwise until it is
tight (Figure 3).
Close Open
FIG. 3
NOTE: This machine is equipped with a pad
centerlock with a left hand thread.
NOTE: Make sure centerlock does not cross thread or

MACHINE OPERATION
FOR SAFETY: Do not operate machine unless
operator manual is read and understood.
PRE–OPERATION
1. Check battery meter charge level to ensure
batteries are fully charged. See CHARGING
BATTERIES.
2. Sweep or dust mop the floor to remove debris.
Then damp mop or scrub the floor to assure that
dirt is not burnished into the finish.
3. Check that a pad is installed.
4. Check that a dust bag is installed.
5. Make sure floor to be burnished is dry.
BURNISHING WITH BR–2250 MODEL
1. Turn key switch to the ”ON”position (Figure 4).
The key ON light on the panel will light green.
FIG. 4
2. With the control grips released, step down on the
rear of the pad shroud until the head locks in the
down position (Figure 5).
FIG. 5
3. Remove foot from the pad shroud.
4. Twist the control grips forward (Figure 6). The pad
motor will start and suction will draw the moving
pad to the floor. Immediately push or pull the
machine in the desired direction.
FIG. 6
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
ATTENTION: Keep machine moving at all times to
prevent floor damage.
5. To stop, release the control grips. The pad will
automatically lift from the floor until the grips are
activated again.
BURNISHING WITH BR–2500 MODEL
1. Turn the key switch to the ”ON”position
(Figure 4). The key ON light on the panel will light
green.
2. With the control grips released, step down on the
rear of the pad shroud until the head locks in the
down position (Figure 5).
3. Remove foot from the pad shroud.
4. Select a speed with the travel speed selection
switch (Figure 7):
UP position provides both slow and fast forward
speeds.
DOWN position provides slow forward speed only.
Use this position for maneuvering in tight areas.

OPERATION
BR–2250/BR–2500(11–01) 7
5. Twist control grips forward until the pad motor
starts (Figure 6). The machine will transport
forward and suction will draw the moving pad to
the floor.
6. To reverse, twist the control grips backward. The
pad motor will start and the machine will transport
backwards.
7. To stop, release the control grips.
FOR SAFETY: When using machine, go slow on
inclines and slippery surfaces.
ATTENTION: Keep machine moving at all times to
prevent floor damage.
8. To increase travel speed (mode switch in ”UP”
position), twist the control grips all the way forward
to select the second (high) travel speed.
9. To stop, release the control grips and hold back on
the machine until it stops moving. The reverse
direction may be used as a stopping brake if
desired.
NOTE: The drive circuit is equipped with a circuit
breaker located on the lower left rear frame. If the
driver system is overloaded during use the breaker will
trip. Allow it to cool for a few moments and reset the
breaker by pushing on the black button (Figure 8).
FIG. 8
ADJUSTING PAD PRESSURE
CAUTION: The pad head must be in the full
up (pad load) position before making the pad
pressure adjustment. DO NOT ADJUST in the
down position as the head could release and
pinch arm or fingers in the mechanism.
1. Your machine has a pad pressure meter located
on top of the control console. This meter has one
green bar and 2 red bars (Figure 9):
GREEN BAR: The operating zone within which the
needle must read.
RED BAR TO THE RIGHT: Indicates too much
pressure or pad resistance.
RED BAR TO THE LEFT: Indicates too low pressure
or that the battery charge is low.
FIG. 9
2. Operate the machine on the actual floor with the
finish and pad you will be using. Notice the needle
position on the meter. For most jobs the needle
should be in the center of the green bar.
3. If the needle is not in the center of the green bar,
raise the pad head into the full up position and
locate the pad pressure knob under the rear frame
(Figure 10).
FIG. 10
4. If the needle indicates too much pressure turn the
knob counterclockwise and repeat testing until the
needle is in the center.
5. If the needle indicates too little pressure turn the
knob clockwise and repeat testing until the needle
is in the center.
NOTE: Increasing pad pressure will improve shine but
it will also reduce battery run time.
ATTENTION: Do not adjust the pressure so the
needle runs in the right red bar. This will cause
the circuit breaker to trip.

OPERATION
8BR–2250/BR–2500(11–01)
6. If high performance is needed and run time is not
a consideration, adjust the pressure so the needle
runs in the higher (right side) of the green bar.
7. If long run time is needed, adjust the pressure so
the needle runs in the lower (left side) of the green
bar.
Once initial pad pressure has been set:
8. If during use the needle moves into the right red
bar, it will cause the circuit breaker to trip. Allow
the pad motor to cool down and then press the
pad motor circuit breaker red reset button.
9. If the needle moves again into the right red bar
and the circuit breaker trips, the pad may have
become dirty and filled with finish. Turn the pad
over to a clean side or replace the pad. Then reset
the circuit breaker. To remove/change pads see
INSTALLING PAD .
NOTE: The operator should watch the pad meter
during operation and change the pad before the circuit
breaker trips.
10. If the needle drops into the left red bar, this
indicates the battery charge is low and recharging
is required. See CHARGING BATTERIES section.
BATTERY LEVEL METER
1. Your machine has a battery level meter located on
top of the control console. This meter has one
green bar and one red bar (Figure 11).
GREEN BAR: The operating zone within which the
needle must read.
RED BAR: Indicates the batteries need to be
recharged. See CHARGING BATTERIES section.
FIG. 11
HOUR METER
1. Your machine has an hour meter located inside
the battery compartment next to the machine
connector (Figure 12).
FIG. 12
2. To gain access to this meter remove the battery
cover.
3. This meter keeps a running total of the hours of
operation of your machine.
4. Use this meter to determine when your machine
should to be maintained.
CARBON BRUSH INDICATOR LAMP
1. Your machine has an amber carbon brush
indicator lamp which will light when the carbon
brushes in the pad drive motor need to be
replaced (Figure 13). See QUARTERLY
MAINTENANCE section.
