ROUTINE AND PERIODIC

MAINTENANCE

Emptying the Spark Trap

The spark trap should be emptied each time a filter is
changed, and more often when the welding conditions
cause high spatter.
a)Remove the hose from the spark trap.
b)Release the latches and pull the trap from
the filter cabinet.
c)Shake the opening of the spark trap over a
waste bin until the trap is empty.
d)Reinstall the trap and reconnect the hose.

Replacing the Filter

The filter cartridge in the Magnum X-Tractor 1GX is dis-
posable and should last through the use of about 400
lbs.of electrode under normal solid wire GMAW condi-
tions. The indicator light on the motor housing will light
up when the filter is in need of replacement.
EXCESSIVE AIR FILTER RESTRICTION WILL
RESULT IN REDUCED VACUUM LIFE. ALWAYS
CHANGE THE FILTER AS SOON AS POSSIBLE
AFTER THE CHANGE FILTER LIGHT ILLUMINATES.
------------------------------------------------------------------------
a)Turn off power to the vacuum.
b)Remove the hose from the spark trap.
c)Release the latches and remove the trap
from the filter cabinet.
d)Pull the filter out of the cabinet.
e)Push a new filter into the cabinet. Be sure it
is fully inserted (a small pipe inside the cab-
inet must be forced through the back of the
filter, so be sure to push the cartridge com-
pletely in).
f)Reinstall the spark trap and replace the hose.

Changing Motor Brushes

If the carbon motor brushes become worn out, replace
them by following the instructions provided with the
replacement brushes.
