Floors are sanded in sanding paths which are arran-
ged overlappingly from left to right.
7.9 Remarks about sanding parquet and plank fl oors
Check the fl oor to see if any boards are loose. These must be fastened before
sanding.
Caution! Fire risk!
If there are nails in the fl oor, they must be countersunk so low every time before
sanding that there is no risk of hitting a nail while sanding.
Hitting a nail while sanding can produce sparks and can cause a fi re.
For example a spark can create a fi re in the dust bag.
