INDEX OF PROBLEMS AND SOLUTIONS
9.1 REPLACING POWER CORD AND PLUGS
When replacing the power cord or plugs, always use cords and plugs with the exact specifications as the original ones. Never use
lower quality or different types of cords or plugs.
In addition, take into consideration the distance of the application from the electrical source. The grater 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 go into alarm
mode. This also happened if several machines are working on the same line or when the generator is underrated. In general, our
standard cable can be doubled in length, if a longer length is needed you can replace all the cables with cables of a bigger gage rated
for the length and the amperage.
9.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGE BUFFERS AND SPIDER, CHANGING V ‐ RINGS AND FELT ‐ RINGS
To check or place the buffers and the spiders, the tool holder has to be dismounted. Remove the countersunk screws on top of the
buffer (Fig.9.2.1). Take the disc off (Fig.9.2.2), the spider can be removed or replaced (Fig.9.2.3). By loosening the four Hex cap bolts
(Fig.9.2.4), the disc comes loose (Fig.9.2.5) and the buffers can be replaced (Fig.9.2.6). Attention, when mounting, always use the “blue”
thread locking adhesive, except on the bolts to lock the buffers (Fig.9.2.5). Always use original bolts. Depending on the number (3, 4, or
6) of buffers, the holder can be more flexible or rigid.
When the tool holder is dismounted, you can change the sealers (V ‐ Ring and Felt ‐ Ring). Take out
felt ‐ ring, Adaptor and V ‐ Ring. Before mounting check on which side the adaptor is fitting,
remember the correct side. Mount the V ‐ Ring with the smallest lip of the V to inside (Fig.9.2.7)
just push the V ‐ ring so the top is on the same level as the pulley top (Fig.9.2.8). Then take the
adaptor in the correct way and push the V ‐ Ring down with the adaptor (Fig.9.2.9). The lowest lip
of the V ‐ Ring should only barely touch its gliding surface; also never push the V ‐ Ring down with
fingers. Mount now the felt ‐ ring on top (Fig.9.2.10). Close the sealers with the cap (Fig.9.2.11).
