Setting up/Operation

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 floor 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 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 increased.
