INDEX OF PROBLEMS AND SOLUTIONS
8.1 REPLACING POWER CORD AND PLUGS
When replacing the plugs always use plugs with specifications as the original ones.
Never use lower quality or different type.
8.2 DISMOUNTING AND MOUNTING TOOL HOLDER TO CHANGING V-RINGS AND FELT-RINGS
To check or replace the buffers and the elastic elements , the tool holders
have to be dismounted.
You will need deep metric socket 13mm with outside diameter not 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).
Take out the adaptor and V-Ring (Fig.8.2.3) (Fig.8.2.4).
Mount the V-Ring with the smallest lip of the V to inside (Fig.8.2.5) just 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; also never push the V-Ring down with fingers. Mount the adaptor
on top (Fig.8.2.7).
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.
