800LE is used to grind (rough grind, fine grind and polish) concrete, natural stone and terrazzo
floors or other materials specified in this manual or recommended by Pantheon .
The 800LE is a self propelled grinder. The forward/reverse switch can be used to control the forward and
backward movement of the driven wheel, so that the user can get rid of the action of manually pulling or
pushing the machine to forward/reverse, which greatly saves manpower and facilitates user operation.
The innovation of this equipment is that it equipped with a water tank and add additional weight iron. The
heat dissipation openings on both sides of the water tank make the heat dissipation of the frequency
conversion box faster and extend the service life of the internal electrical appliances. The design of the
water tank allows the equipment to be applied not only in dry grinding but also water grinding. The
benefits of water grinding are as follows: good flatness, small cutting amount, easy polishing, suitable for
later stone polishing.Increasing additional weight makes the lifting easier, and the grinding pressure can
be increased during grinding to make the ground smoother.
The swing lever and handle can be set in many different tilted positions. When the machine is manually
operated, you can choose the most suitable position. The grinding head of the machine can be used with
different grinding plate for operation. The dust belt covers the working area of grinding head. Because of
floating design, it always touch the floor, which not only ensures that the operator does not touch the

rotating mechanical parts, but also reduces the exposure of dust and improves the dust absorption efficiency of
the vacuum cleaner.
When dry grinding, to prevent dust from being exposed to air, posing a threat to the health of the operator and
nearby people, make sure that the vacuum cleaner is connected to grinder (preferably equipped with a vacuum
cleaner manufactured by Pantheon ) Due to inhalation of dust is harmful in the course of operation, even there is
a vacuum cleaner protective mask is also necessary to protect health.
The machine can use different Pantheon abrasive. Due to the different ground materials, the abrasive discs
used in grinding are also different.
