GEMINI 100 User Manual_April 2013 Edition
Machine control instructions
The Gemini 100 is defined as a steering sander due to its innovative control characteristics (patent pending). The
point of pressure is related to the chosen direction whereby the pressure exerted on one side moves the machine
in the same direction.
Therefore the machine moves left and right on the basis of the force and pressure applied to the handle.
Until now all small single disc sanders
have required point pressure i.e. a load
perpendicular to the centre of the
machine, whereas the Gemini 100
steering sander has two counter
rotating discs. The thrust of the left disc
(towards the inside i.e. towards the
right) is counterbalanced by the thrust
in the opposite direction exerted by the
right disc (which pushes towards the
left).
The correct operator position for
optimum control is behind the machine
and not at the side (as many tend to
do), with the hands on the two handles.
Once the machine has been started it
can be noted that it remains quite
stationary even though the discs in
contact with the floor are turning.
To move the machine to the right exert a light downward pressure on the right handle.
To move the machine to the left exert a light downward pressure on the left handle.
The picture above makes it easier to understand machine operation.
WARNING
It is prohibited to place
objects on the base
frame to load the tool or
load the front part of the
base frame with the
weight of the arms or
body.
