Speed And Direction Of Rotation - Husqvarna PG 820 RC Manual De Instrucciones

Speed and direction of rotation

General
The planetary head and grinding discs are driven by
separate motors, Dual Drive Technology™. This gives the
operator full control of the speed of both the planetary
head and the grinding discs independently of each other.
Speed and direction of rotation are set with the knob on
the control panel or remote control.

Speed
When starting the machine for the first time on any given
application, it is advised the speed setting should not
exceed 7, initially.
When the operator is comfortable with the application,
speed may be altered.
Direction of rotation
Seen from underneath the machine, the direction of
rotation is as follows:
• REV - Clockwise.
• FWD - Reverse.
The machine will 'pull" to one direction during operation.
The direction of pull is determined by the planetary head
direction of rotation. The head of the machine will pull to
the right (and therefore, will be felt on the right hip of the
operator) when the planetary head is set in the REVERSE
direction.
This sideways pull can be very useful when grinding,
particularly along a wall. Set the machine so that it pulls
towards the wall, and then control the machine so it can
just touch the wall. This will ensure a grind close to the
wall or object.
Grinding is more efficient when the planetary head and
the grinding discs rotate in the same direction. The end
result is higher productivity than when the discs are set to
run in opposite directions. It is here that you will also
experience the beneift of Dual Drive Technology™.
Change the direction of rotation regularly so the
diamonds will retain their efficiency. Both sides of the
