GROUNDING INSTRUCTIONS
WARNING: The dust collector must be
grounded to protect the operator from
electric shock. Not all outlets are
properly grounded. Have your outlets
checked by a qualified electrician.
All grounded, cord connected tools:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current
in order to reduce the risk of electric shock.
This machine is equipped with an electric cord having
an equipment-grounding conductor and a grounding
plug. The plug must be plugged into a matching out-
let that is properly installed and grounded in accor-
dance with all local codes and ordinances. Do not
modify the plug provided if it will not fit the outlet; have
the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding con-
ductor can result in risk of electric shock. The con-
ductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment grounding conductor to a live terminal.
Check with a qualified electrician or service personnel
if the grounding instructions are not completely under-
stood, or if in doubt as to whether the machine is prop-
erly grounded.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tools' plug. Repair or replace any damaged or
worn cord immediately.
As the three phase 230/460 volt motor does not have
a plug, please carefully follow the rotation direction of
the impeller when connecting to the power source.
EXTENSION CORD
Use only a 3-wire extension cord with a 3-prong
grounding plug and a 3-pole receptacle as shown in
Figure 16. Replace a damaged or worn cord immedi-
ately. The use of an extension cord, if required, re-
sults in a certain loss of power. The recommended
wire gage is no. 10.

OPERATION
SWITCH
The switch box attached to the impeller housing is an
industrial type switch with standard "start" and "stop"
push buttons.
MOTOR
Motors used in a woodworking environment are con-
stantly exposed to sawdust and wood chips. The
operator should make frequent inspections of the mo-
tor and remove, or vacuum, any accumulation of for-
eign material in order to maintain normal motor venti-
lation.
Remove dust from the motor with a low pressure air
hose.
CAUTION: The operator should follow all
safety procedures regarding dust
particles and always wear safety goggles
and a filter mask during any cleaning
operation.
MAINTENANCE
CAUTION: Never perform maintenance
on this machine before pushing "stop"
and removing plug from power source.
DUST BAGS
Each operator has his own particular application of
woodworking machinery. As such, a maintenance
schedule for the dust collector must be performed on
a regular and timely basis. To remove dust and chips:
1. Disconnect machine from its power source.
2. Shake the upper dust bag and allow the fine dust
to settle down into the lower bag.
3. Release the clamp around upper bag, remove the
upper bag and deposit all remaining dust into a fire-
proof metal container.
4. Release clamp around lower bag, remove the
lower bag and deposit chips and dust into a fire-proof
metal container.
5. Reconnect both sets of dust bags making sure
the clamps firmly secure the bags to the housings.
