5.1 APPLICATION TIPS
ATTENTION!
• Always sand from left to right! This ensures that the left-
hand lateral wheel always runs over the newly sanded
surface, making the surface more even with each sanding
pass and preventing waviness!
• One sanding track comprises a forward and reverse
movement over the same lane without offset!
• We advise a sanding track offset of 50%!
•
Deep sanding marks due to the selection of a too coarse grit
grade can be prevented by starting the first sanding operation
with the finest grit grade possible.
•
Carry out a test sanding process using a 50 or 60 grit grade
(a few test sanding tracks). If this test is satisfactory and you
envisage a good sanding result within a reasonable period,
it is more efficient to start the sanding work with these finer
grit grade.
•
Prevent sanding marks made by previously used grit grade by
adhering to the order of the sandpaper grit grade and never
skip more than one grit grade.
•
Vacuum the floor thoroughly always directly
before each
workstep (every sanding step, gap filling or surface treat-
ment).
•
Clean the wheels of the machine before starting each new
sanding operation.
•
In order to avoid chatter marks, use sanding belts with bud
joints and tape.
•
After replacing the sanding belt, start working in poorly lit
areas of the room in order to remove the initial aggressiveness
of the sanding medium.
