NSS CHARGER 1500 Mode D'emploi page 5

Setting Pad Pressure (Charger 2500 Only)
Pad pressure relates to buffing performance. Too
much pad pressure will give uneven results, may
score the floor, and may cause the circuit breaker to
trip. Too little pad pressure will result in poor
burnishing performance. Since new pads are
different thicknesses and all pads thin down during
use, periodic adjustment of pad pressure is required.
Pad pressure is adjusted using the adjustment knob
on the front of the machine as follows:
 Begin by turning the adjustment knob clockwise,
until the pad only slightly touches the floor.
 Run the machine and observe the gauge on the
motor cover, which should show minimum pad
pressure with the indicator all the way to the left.
 Turn the adjustment knob counterclockwise until the
indicator is approximately centered in the green
area.
NOTE: Machine must be moving. Operating in one
place will damage the floor.
 Continue to observe this gauge during operation
and adjusting as necessary.
NOTE: If the circuit breaker on the machine trips,
immediately reduce pad pressure by one full turn or
more of the adjustment knob.
Running the Machine
 Floors should be dust mopped to remove surface litter
and damp mopped to remove grit (preferably
scrubbed with an autoscrubber), otherwise the buffer
will anneal dirt into the finish.
 Start at a point nearest the electrical outlet and walk
as far as the cord will let you travel. Make a 180-
degree turn away from the cord and walk the
machine in a path parallel to the first pass, slightly
overlapping the preceding path.
 Never buff in one location for more than 5 seconds,
especially if using the Charger 2500, or scoring of the
floor finish or tile may result.
 Without letting go of the handle, release the switch
levers to stop machine.
CAUTION: Machine pad will continue to rotate a few
seconds after the switch lever is released.
Over-Load Protection
A circuit breaker is located on the right hand side of the
switch box below the switch lever. The circuit breaker
is designed to prevent operator induced overloads. If
the circuit breaker trips, the machine is experiencing an
overload situation.
To prevent the circuit breaker from tripping, reduce pad
pressure (Charger 2500 only), change pads more often
or reduce the amount of spray cleaner, spray buff, etc.
being applied to the floor. For the Mustang 1500 and
Electric Charger, do not lift up on the handle, as this
will also cause an over-load condition.
If the circuit breaker continues to trip, do not run the
machine. See the "Troubleshooting" section, or
contact your authorized NSS service center.
Applications
Charger 1500 and Mustang 1500
Operations you can perform with these machines:
 High speed buffing/polishing
 Spray buffing
 Use any thick pad of any type
 Damp stripping
Operations you cannot perform with these machines:
 Wet scrubbing (flooded floor)
 Carpet shampooing
 Operating with weights added
Utilize more aggressive pads, such as the NSS "Blue"
pad to help remove scuffing and surface soiling.
Charger 2500
The Charger 2500 is recommended for dry polishing or
burnishing of marble or Terrazzo floors. Use mop on
restorers rather than spray buff systems to restore the
shine.
Do not spray buff because it is time consuming, uses
more pads because they become loaded with floor
finish, will ruin the Velcro liner on the skirt, and can
cause overloading of the machine's circuit breaker.
The blue NSS pad can be used to remove layers of
wax on dry surfaces or while the floor is still wet from
damp mopping with cold water or a neutral cleaner.
Operations you can perform with this machine:
 High speed buffing/polishing
 Buffing mop-on restorers (after drying)
 Buffing damp floors mopped with a neutral cleaner
or plain water
Operations you cannot perform with this machine:
 Wet scrubbing
 Spray buffing
 Carpet shampooing
 Operating with weights added
Important Tips for Buffing
Floor Pads – Polishing
The selection of which floor pad to use is contingent
upon several factors, including hardness of the floor
finish being used, the color of the floor tile (light or
dark) and the general frequency of dust mopping, wet
cleaning, and high speed buffing. Given these
variables, choosing the WRONG pad can lead to FAR
LESS than optimum results. For example, if a swirling
or smearing effect appears while buffing, the pad
being used is too abrasive or dirty. A new, clean pad
or a softer pad is necessary to attain a uniform level of
high gloss. If you are unsure as to which pad is
correct for a particular situation, consult your NSS
distributor.
Floor Pads – Spray Buff/Restorer Products
When spray buffing or using a restorer or top-dressing
type material, the pad must be a more aggressive
material than, for instance, a white super speed polish
pad, to remove residue and haze left by the mopped-
on or sprayed-on material.
