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 DISMOUNTING TOOL HOLDER TO CHANGING V‐RINGS AND FELT‐RINGS
Figure 8.2.1
Figure 8.2.5
To check or replace the buffers and the elastic elements, the tool holders have to be dismounted.
You will need a 13mm deep metric socket with an outside diameter of no more than 3/4in to unscrew the four bolts (Fig.8.2.1) and
remove the holder (Fig.8.2.2) When the tool holder is dismounted, you can change the sealers (V‐Ring and Felt‐Ring).
By loosening four Hex cap flange bolts (Fig.8.2.3) the adaptor comes loose. Unscrew the six screws of the cap (Fig.8.2.4) holding the
felt‐ring. Take out the Felt‐Ring, adaptor and V‐Ring.
Mount the V‐Ring with the smallest lip of the V to the inside (Fig.8.2.5) ‐ simply push the V‐Ring so the top is on the same level as
the pulley top (Fig.8.2.6). Then take the adaptor and push the V‐Ring down with the adaptor (Fig.8.2.7). The lowest lip of the V‐Ring
should only barely touch its gliding surface. Mount the adaptor and the Felt‐Ring on top (Fig.8.2.7). Close the sealers with the cap
(Fig.8.2.8) and screw the bolts. Always use the original bolts. Do not push the V‐ring down with fingers.
8.3 DISASSEMBLING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND ELASTIC ELEMENT
When the TOOL HOLDER is disassembled you can change defective parts – elastic element, buffers, etc.
Lift the locking pin (Fig.8.3.1) to dismount the retaining washer (Fig.8.3.2). Take out the screws on the buffers and the nuts of the
elastic element (Fig.8.3.3;Fig.8.3.4). Remove the elastic element from the QC plate (Fig.8.3.5). While the holder is dismounted
(Fig.8.3.6;Fig.8.3.7) clean the parts and replace the defective with new ones. Assemble the holder with new buffers with new screws
and new elastic element. Put the retaining washer (Fig.8.3.8) and push the locking pin (Fig.8.3.9). This will prevent the fall of the
washer when mounting the holder on the machine.
