machine
WARNING
NEVER GRIND OR SAND ANY ALUMINUM OR MAGNESIUM, OR ANY
SPARK CREATING PRODUCT ON THIS MACHINE
Filters are the main need of maintenance, the cleaner the filters are kept the better the machine will
perform. This machine is equipped with timers to clean the filters, every so many minutes a pulse of
air will be released into one of the filters, and a few minutes later the other filter will be pulsed, the
time is needed to refill the tank. The time between pulses are adjustable, refer to the electrical
diagram. Warning if the time is reduced between pulses the filter may plug up reducing the
machines performance. The filters can also be pulsed with the machine off, it may blow dust back
into the work area, so caution should be used here, pulse the machine then turn machine on to pull
dust back into the filters.
The filters will clean better with machine off,
you may shut machine off and before it slows
down to a complete stop, pulse the filter and
allow the fan to prevent the dust from exiting
the filter compartment.
Filter replacement number is on the inside of
the filter door.Be sure to replace with same
type of filter or a filter made of polyester
media.
Cartridge Filters 99.95% efficeincy
down to .5 micron
The exhaust air will exit through
opening to the floor, if muffler
is added the plate on the end will
be located here to force the air
through the muffler

TROUBLE SHOOTING
Motor not running Look to see if L1- L2 -L3
wires are in and secured
and proper voltage is there
Check if wires at bottom of
mag starter to the motor are
in bottom and secured.
The above checks OK In center of the contactor is a rectangle post that is
hooked to coil below. With screwdriver push in and see
if motor will run. If motor will run something is wrong
with the push buttons, That activates the starter.
Motor runs when center
post is held in, but not
by the switches
Make sure every wire is secured on starter if
still no results call Denray for further assistance
If center post is held in
and nothing happens
hook power leads to motor
leads at bottom of mag
starter if motor runs the
problem is the starter.
Call factory for switch replacement
If on switch closes mag
starter and motor does
not run.
FIRST take tester and check see if there is the
proper voltage at bottom of starter
If proper voltage is at
bottom of starter Check to see wiring at motor is properly
hooked together
All the below solutions are meant to be done
only by a qualified technician
Mag starter works
and motor only hums Check for proper voltage
check all wire connections to be tight
check wiring diagram and motor leads to be correct
Filter Cleaning valve will
not pulse Check the three 1 amp fuses on
top of the transformer in the
switch box.
Fuses OK Check wiring in front of and behind the fuses
