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.
GROUNDING INSTRUCTIONS
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 tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug.
The plug must be plugged into a matching outlet that
is properly installed and grounded in accordance 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 con-
nection of the equipment-grounding conductor can re-
sult in risk of electric shock. The conductor with insu-
lation having an outer surface that is green with or
without yellow stripes is the equipment-grounding con-
ductor. 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 tool is properly
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 dam-
aged or worn cord immediately.
As the three phase 230/460 volt motor does not have
a plug, please carefully follow the rotation direction of
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 1. 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 is an industrial type switch with stan-
dard "start" and "stop" push buttons, and is attached
to the impeller housing unit.
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.
