Checking Conditions Of The Floor; Operating The U-Sand® Equipment - USand BT700 Manual Del Operador

CHECKING CONDITIONS OF THE FLOOR

Check for condition of floor using one of the following tests and follow appropriate directions:
Wax Floor:
Place a damp cloth (approx. 18" x 18") on the floor. Lift after an hour and check for any cloudy
coloration. A white cloudy coloration indicates wax. In this case, strip the wax using a wax stripper
before sanding is attempted. Excess wax will clog the sandpaper.
Painted Floor:
Chemically remove paint before attempting to sand floor.
Varnished Floor:
U-Sand® equipment will remove most kinds of varnish. Excessive layers of varnish, however, may
require chemical removal before attempting to sand the floor.
Unfinished Floor:
Start the sanding process with the least aggressive grit as possible, progressing to the finer grits of
sandpaper ranging from 24 grit (the most aggressive/coarse) 36, 40, 60, 80, 100, 120 grit (less
aggressive, coarse). Etc.
OPERATING THE U-SAND® EQUIPMENT
WARNING: Always remove the electrical plug from the electrical outlet before installing and
changing the sandpaper.
Select the paper to start:
Select the least aggressive grit as possible that removes the desired amount of surface. Too aggressive
grits leave swirl marks that are difficult to remove with finer grits that will be used later. Grits that are
not aggressive enough do not take enough of the surface off and result in more work and a slower
process
Installing Paper:
Sandpaper should be installed by leaning the machine back and placing the sandpaper on the backer
pads (BP6).
Changing Sandpaper:
Paper should be changed when you notice less pull when running the equipment and see less material
being removed by the process (10-15 minutes).
CAUTION: To prevent damage to backer pads, you must change sandpaper when it becomes
loaded or clogged.
