Cleaning the Vacuum Filter (only with the vacuum chip removal option)
On systems with a vacuum chip removal system, frequent cleaning of the vacuum filter is
necessary for proper performance. When engraving with the vacuum filter system, the filter
should be checked and cleaned several times a day, depending on the amount of engraving
done. If the vacuum does not appear to be functioning efficiently, clean the filter more fre-
quently as needed.
To clean the vacuum filter system, disconnect the vacuum hose from the canister. On the lid of
the canister, note the three wing nuts. Loosen these nuts enough to allow the attached bolts to
swing away from the lid, allowing removal of the lid. Do not loosen the nuts enough to remove
them completely. Remove the canister lid and inside you will find two filters. Carefully remove
the inner, paper filter. (The paper and cloth filters tend to stick together.) Empty the paper filter,
and shake it out completely, being careful not to damage it as the filters are reusable. After
shaking out the paper filter remove and empty the cloth filter in the same manner as the paper
filter. Do not wash either filter. Place the paper filter back inside the cloth filter, and place the
cloth filter back inside the vacuum canister.
REPAIRS, REPLACEMENTS, AND ADJUSTMENTS
How to replace a belt
A belt is used to drive the spindle engraving system. It runs between a drive pulley and the
spindle pulley (see Fig.2.2 in Chapter 2). If it needs replacement, remove the old belt by rolling it
to the top of the spindle pulley, and give it a slight stretching motion to snap it off the end. Once
loose, it can easily be removed from the machine. Now position the new belt around the drive
pulley, then stretch it to snap over the top of the pulley.
NOTE: Be sure to puchase the specified replacement belt from Western Engravers
Supply. Having the exact tightness is extremely important to the functionality of the
motor. NEVER STRETCH THE BELT!
