8. TROUBLESHOOTING
INDEX OF PROBLEMS AND SOLUTIONS
8.1 REPLACING POWER CORD AND PLUGS
When replacing the power cord or plugs always use cords and plugs with specifications as the original ones.
Never use lower quality or different type cord and plugs.
In addition, take into consideration the distance of the appliance from the electrical source. The greater the distance, the
greater the resistance and the less current that will be available at the other end; there will be a voltage drop and the
inverter will sign alarm mode. This can also happen if several machines are working on the same line or when the generator
is underrated. In general our standard power cable can be doubled in length; if longer lengths are needed you have to
replace all the cables with bigger gage rated cables for the length and amperage.
8.2 CHANGING THE TOOL HOLDER AND THE FLEXIBLE PAD
Unscrew the handle in the center of the tool (Fig.8.2.1). Unscrew the four bolts seen on the central part (Fig.8.2.2) and
remove the tool holder and the flexible part. Then unscrew the three screws as shown on (Fig.8.2.3) and unscrew the six
visible screws underneath (Fig.8.2.4) to dismount the flexible pad.
8.3 TENSIONING THE BELTS
PLEASE MAKE SURE YOU CHECK THE TENSION OF THE BELT AFTER THE FIRST 15 HOURS OF OPERATION
If the operator notices the grinding spindle turning irregularly/noisily or - at worst – not spinning as the motor turns, the
belt should be checked.
ATTENTION: NEVER “OVER” TENSION THE BELT, THE BELT WILL BE DISTROYED AND IT WILL NEVER RECOVER ITS ORIGINAL
TENSION
Turn the screw (Figure 8.3.1) clockwise to tighten the belt. The
tightening force on the belt should be 581 N measured by
OPTIKRIK II
