Husqvarna PG820 Grinder User Manual


 
10 - English
Setting up/Operation
Position grinder on the working area. Make sure there
are diamonds underneath machine and that the head
locks/shear pins are tight.
IMPORTANT!
When using the machine, each grinding head
must always have the same diamond type
and number of diamonds as the other grind-
ing heads. Each grinding head must have
diamonds the same height as the other grind-
ing heads.
Adjust rubber skirt so that a good seal is established
between the oor and head of machine (see picture
below). Ensure join in skirt is at the front of the ma-
chine. Setting of the skirt is essential to obtain good
dust extraction and eliminate the possibility of airborne
dust when dry grinding.
Set handle to most comfortable working height using
adjustment lever.
IMPORTANT!
It is recommended that this height be set as
close as possible to the height of the opera-
tor’s hip bone. When the machine is running,
there will be a grinding force/pull to one side
that can be felt through the handlebars. Use
the hip to resist this force instead of trying to
control this through the arms (such position-
ing will be much easier for the operator using
the machine over prolonged periods of tim.
Powering up machine
i. Ensure the STOP/RUN switch is set on Stop
(rotate counter clockwise).
ii. Plug power supply to machine. Only turn power on
at
switch once fully connected.
iii. Disengage Emergency Stop button (twist clock-
wise).
iv. Depress Power button. On doing so, a soft “clunk”
should be heard to come from within the electrical cab-
inet. This indicates the line contactors have engaged,
supplying power to the drives/frequency converters.
Setting Speed and direction
On the control panel there is a FORWARD/REVERSE
and Speed dial knob. Generally, when starting the
machine for the rst 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 increased.
