FLOOR SANDING TECHNIQUE
HT8 Multi-Speed Drum Floor Sander - a powerful
floor sander designed for the rapid leveling and
sanding of all types of wood flooring excluding thin
laminated or veneered floors. Load the sander with
abrasive making sure that it is skin tight around the
drum. Loose sheets will tear. Place the sander on the
right hand wall (unless you are making an angled cut
on uneven floors) with about two thirds of the floor in
front of you.
Start the sander with the drum off the floor. When first
connected to the power supply the 8 Multi-SpeedHT
will default to the slowest speed, button ‘1’. Press and
hold the / (I/O) button for 1.5sec to start theON OFF
HT8 and then select the correct speed depending on
the abrasives grit fitted and the application. See 8HT
Multi-Speed Abrasive and Speed Application Chart
below.
Walk forward at an even pace and ease the drum on
to the floor. Walk at an even pace allowing the 8 toHT
do the work, do not hold the floor sander back.
Simple guide and control the direction.
As you near the end of the pass, gradually raise the
drum off the floor. Practice this technique before
turning on the sander.
Cover the same path you made on the forward cut by
pulling the machine backwards and easing the drum
to the floor as you begin to walk backwards until you
reach the original starting point, then ease the drum
off the floor.
When two thirds of the floor is sanded, turn the floor
sander around and sand the remaining third in the
same way. Overlap the one third area by 0.5 meters
(1½’) with the two thirds area to blend the two areas
together.
WARNING - never bounce the sanding
drum or dwell in one place as this will
sand dips and hollows in the floor.
HT7 Disc Floor Sander (Edger) - a powerful disc
floor sander designed for sanding along the edges of
a floor without damaging the baseboards or
moldings. Also suitable for smaller areas where the
HT8 Multi-Speed Floor Sander will not reach like stair
treads and closets.
Load the abrasive disc making sure the retaining bolt
is tight. Start the edger with the disc off the floor then
lower the disc to the floor as you move the sander.
Work progressively moving the sander in a sweeping
motion from side to side.
HTF Orbital Floor Sander - an orbital action floor
sander designed for re-finishing, sanding between
coats of varnish and re-surfacing floors in good
condition.
Load the abrasive pad and abrasive sheet. Start the
sander, move immediately and sand in the direction
of the grain using the same technique as the drum
floor sander. For difficult to reach areas use the disc
floor sander with a fine grit abrasive, or sand by
hand.
