To operate the machine follow this procedure:
1. Install the operator's belt as follows:
a. Position the operator's belt around waist.
b. Cross the straps at the waist. See figure 5.
c. Slide the belt loop end over the handle on
the control lever side. Adjust the length as
needed.
d. Wrap the remaining strap around the op-
posite side of the handle and hold it in place
with your hand.
WARNING: Should quick release of the
machine be necessary, serious
operator injury could occur if
the operator has tied the loose
end of the operator's belt strap
to the machine. Always position
the strap so that you can let go
and get away quick in case of
bag fire or explosion.
2. Put the On/Off switch into the "ON" position.
DANGER: Serious damage can occur to the
floor surface if the machine is not
in motion while the contact wheel
is running on the floor surface. To
prevent damage to the surface,
make sure the machine is always
moving when the contact wheel
is in contact with the floor.
3. Work right to left. For each forward pass, move
the machine 4" over the pass you have just
finished. Retrace your reverse path without
overlapping. See figure 6.
4. Feather-cut in by easing the contact wheel down
onto the surface with the control lever while the
sander is in motion.
5. When contact wheel is fully engaged with the
surface, gradually adjust your pace for adequate
finish removal. Keep sander in motion while the
contact wheel is engaged with the surface or
dwell marks will occur.
6. Move the machine in the direction of the grain
in the wood whenever it is possible. Sand the
surface at a constant pace.
7. Gradually feather-cut out at the termination point
(the end of your pass) by easing the contact
wheel up with the control lever. Stagger the ter-
mination points for a better blend when edging.
8. Empty dust bag whenever it is 1/3 full. Never
leave a dust bag unattended with sanding dust
in it. Sanding dust can spontaneously ignite
and cause a fire or explosion. Empty dust into a
metal container located outside of the building.
