SAFETY RULES

Read the Manual. Always read the owner's manual carefully before attempting to use the machine. Know the

limitations and hazards associated with its use.

Eyes. Always wear approved safety goggles or glasses that comply with ANSI Z87.1 when operating this ma­chine. NOTE: Common eyeglasses are only impact resistant, they are not safety glasses.

Dress Code. Do not wear loose clothing, neckties, jewelry, or gloves that can get caught in moving parts. Confine
long hair. Keep sleeves above the elbow.

Electrical Grounding. Your machine must be electrically grounded. If a cord and plug are used, make certain the
grounding lug connects to a suitable ground. Follow the grounding procedure indicated by the National Electric
Code.

Guards. Keep machine guards in place at all times when machine is in use. If removed for maintenance pur­poses, use extreme caution and replace the guards immediately.

Do not overreach. Maintain a balanced stance at all times so that you do not fall or lean against blades or other
moving parts.

Power off. Make sure the machine is either unplugged or electrically disconnected and locked out when perform­ing maintenance or service work.

Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, stock,
and cleaning rags from the machine. Keep the area around machine clean and free of scrap material and sawdust
to mimimize the danger of slipping.

Power on. On machines equipped with a manual starter make sure the starter is in "STOP" position before
connecting power to machine.

Use the right tool. Don't force a tool or attachment to do a job which it was not designed for.

Check damaged parts. Check for alignment of moving parts, binding of moving parts, breakage of parts, mount-

ing, and any other condition that may affect the machine's operation. A guard or other part that is damaged should
be properly repaired or replaced.

Turn power off. Never leave machine running unattended. Do not leave machine until it comes to a complete
stop.

No horseplay. Give your work your undivided attention. Looking around, carrying on a conversation, and "horse­play" are careless acts that can result in serious injury.

Use recommended accessories; improper accessories may be hazardous.

Collect wood materials only. Metal shavings and dust can set wood dust on fire.

Do not expose the dust collector to moisture or wet surfaces. Use only indoors and on a dry surface to avoid the

risk of electrical shock.

Do not use the dust collector around flammable products. Sparks may ignite the vapors. Do not pick up anything
that is burning or smoking.

Do not operate the dust collector without the hose connected to the suction chute. Hazardous moving parts are
inside and could cause serious injury.

4

Do not put any objects into openings. Do not use with any opening blocked; keep free of dust, lint, hair and
anything that may reduce air flow.

Drugs, alcohol, medication. Do not operate machine while under the influence of drugs, alcohol, or any medi­cation.

Health Hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some ex­amples of these chemicals are:
* Lead from lead-based paint.
* Crystalline silica from bricks and cement and other masonry products.
* Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment, such
as those dust masks that are specifically designed to filter out microscopic particles.

Familiarize yourself with the following safety notices used in this manual:

!

CAUTION: (This means that if precautions are not heeded, it may result in minor or moderate injury

and/or possible machine damage)

!

WARNING: (This means that if precautions are not heeded, it could result in serious injury or

possibly even death).

GROUNDING INSTRUCTIONS

OPERATION

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 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 connection of the equipment-grounding con­ductor can result in risk of electric shock. The con­ductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment­grounding 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 under­stood, or if in doubt as to whether the machine is prop­erly grounded.

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 con­stantly exposed to sawdust and wood chips. The
operator should make frequent inspections of the mo­tor and remove, or vacuum, any accumulation of for­eign material in order to maintain normal motor venti­lation.
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.

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 immedi­ately. The use of an extension cord, if required, re­sults in a certain loss of power. The recommended
wire gage is no. 10.

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 fire­proof 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.
