For Your Own Safety, Read Instruction

Manual Before Operating This Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor­tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

machine to avoid machine damage.

Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching
live electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.

DISCONNECT POWER FIRST.
nect machine from power supply BEFORE mak­ing adjustments, changing tooling, or servicing
machine. This prevents an injury risk from unin­tended startup or contact with live electrical com­ponents.

EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.

Always discon-

-10 -

Model T33150/T33151 (Mfd. Since 03/22)

WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate­rial. Always wear a NIOSH-approved respirator to
reduce your risk.

HEARING PROTECTION. Always wear hear­ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica­tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.

FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.

NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement dur­ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec­ommended accessories. Using improper acces­sories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.

MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!

MAINTAIN POWER CORDS. When disconnect­ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend­ed operation, stop using the machine! Contact our
Technical Support at [phone].

Additional Safety for Air Filters

Long-term respiratory damage can occur from using this filter to capture hazardous dust
without proper use of a respirator. Collecting flammable or combustible liquids, vapors, or
explosive dusts can cause fire or explosions, resulting in smoke inhalation, serious burns,
or death. An improperly secured air filter can fall, causing head injuries. To reduce the risk of
these hazards, operator and bystanders MUST completely heed hazards and warnings below.

LUNG PROTECTION. Fine dust that is too small

to be caught in filter will be blown into ambient
air during operation. Always wear a NIOSH­approved respirator during operation and for a
short time after to reduce your risk of permanent
respiratory damage.

INTENDED USE. Using this filter regularly to
collect prohibited materials can result in serious
health problems. It is only designed to capture
dust from ambient air in a woodworking shop for
a short time after cutting or sanding operations.
DO NOT use to collect particles of silica, polyure­thane, metal, lead paint, asbestos, or hazardous
bacterium. DO NOT allow filter to collect explosive
dusts, flammable or combustible liquids or fumes,
burning or smoking material, or toxic fumes. DO
NOT connect directly to air filtration system. Only
operate with filters installed.

HAZARDOUS DUST. Dust exposure may cause
cancer, birth defects, or long-term respiratory
damage. Be aware of dust hazards associated
with each workpiece material, and always wear
a NIOSH-approved respirator to reduce your risk.

DUST ALLERGIES. Dust from certain woods
may cause an allergic reaction in people and
animals. Make sure you know what type of wood
dust you will be exposed to in case of an allergic
reaction.

POWER DISCONNECT. Turn switch OFF, dis-
connect air filter from power supply, and allow
impeller to come to a complete stop before doing
any cleaning, maintenance, or service.

OPERATI NG LOCATION . DO NOT operate the
air filter in rainy or wet locations—exposure to
water may create a shock hazard or decrease the
life of the machine.

REGULAR CLEANING. To reduce risk of start­ing a fire, regularly clean surrounding area where
machine is operated. Excessive fine dust buildup
on overhead lights, heaters, electrical panels,
or other heat sources can increase risk of fire.
Regularly check/clean/change filters to avoid fine
dust buildup.

EMPTYING DUST. To reduce exposure to wood
dust when removing dust from filters, which may
increase risk of allergic reactions or respiratory
problems, always turn switch OFF, disconnect
power, and wear a respirator and safety glasses.
To reduce fire and explosion risk, empty dust
away from ignition sources and into an approved
container.

SUSPENDED DUST PARTICLES AND IGNITION
SOURCES. To reduce risk of death or injury

caused by explosions or fires, DO NOT operate fil­ter in areas where these risks are high, including,
but not limited to, spaces near pilot lights, open
flames, or other ignition sources.

MOUNTING. To reduce risk of injuries due to fil­ter falling, secure it to load-bearing joists or wall
studs that can support its weight. Do not mount
unit only to sheet rock, pressboard, paneling, or
honeycomb ceiling panels with expansion-type
fasteners, which can easily tear out.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the avail­ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.

or equipment damage
may occur if machine is
not properly grounded
and connected to power

The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.

The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.

If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over­loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con­sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.

A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup­ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec­essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.

Check with a qualified electrician or service per­sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon­nect it from power, and immediately replace it with
a new one.

Site Planning

Site planning is an important step to maximize the
effectiveness of the hanging air filter. Air circula­tion must be thought out and all obstructions to
the air path considered.

Think of air circulation in terms of the circular
motion of the air before and after the air filter. The
air exiting the filter moves at a higher velocity than
the air entering it. Consequently, exhaust being
vented inside a building can have an effect on the
pattern of air circulation.

Air circulation patterns will vary depending upon
which air flow speed is used and according to
your specific shop setup. Figure 11 shows an
example of good air circulation.

Figure 12 shows an example of poor air circu­lation, where the air filter is placed too close to
obstructions. In this situation, the velocity of the
air is lost and circulation is diminished.

Air

Filter

Figure 12. Poor air circulation. Air filter is placed

too close to the wall so air circulation short

cycles, leaving much of the room unfiltered.

Air

Filter

Figure 11. Good circulation. Air filter placement

promotes circular air motion.

Below is a list of things to keep in mind when
selecting a spot for the air filter:

• Study your shop layout and try to determine
the best location for the hanging air filter.
Air flow that is obstructed will cause a short
cycle effect, producing unsatisfactory results.
There must be a clearance of at least 3 feet
from any obstructions in front and back of the
unit.

• Try to place the air filter in front of high dust
producers like sanders or near areas where
sanding will take place.

• Do not place the hanging air filter where
garage doors may pass closely or where it
may impede transport or movement of any
other object.

• Try to place the unit where it is easy to access
for turning it on, cleaning and maintenance.

The Models T33150 and T33151 can both be
hung from the ceiling with the included eye bolts.
However, the T33150 also includes rubber feet, so
the machine can be placed on a bench or table for
easy access.

If hanging the air filter from the ceiling, it is very
important that the machine be supported properly.
Please follow these guidelines when planning
where to mount the air filter.

• The air filter can only be hung from the eye
bolts that screw into the top of the machine.

The air filter can be used as a portable air filtration
system by installing the rubber feet and placing
the unit on a workbench or a table.

use power lifting equip­ment such as a forklift to
move heavy items.

To install machine on workbench:

• Make sure that an electrical outlet with a
properly grounded receptacle is available at
the location you choose.

• The hanging air filter must be supported by
wood joists. These joists should be capable
of supporting at least 100 lbs each. DO NOT
attach the hanging air filter to only sheet rock,
press board or paneling. These materials
cannot support the filter, and it may fall.

• Avoid hitting your head on the hanging air
filter. Make sure there is enough clearance
between the unit and the ground, especially
important in a basement. If possible, posi­tion the air filter in an area that has little
foot traffic but still offers easy access to the
control panel and filters.

1. With help from an assistant, carefully flip air
filter on its side.

2. Thread (4) rubber feet into holes on bottom of
machine (see Figure 13).

Figure 13. Rubber feet installed.

3. Place machine on workbench in location that
conforms to recommendations under Site

Hanging Installation

The air filter can be hung from the ceiling using
four equal lengths of chain, cable, or steel
strapping rated for the weight of the machine.
For safe clearance beneath the machine, the air
filter should hang no less than 7' from the floor.

ONLY mount the air filter unit to joists or
table that can hold at least 100 lbs. DO
NOT mount the unit only to sheet rock,
pressboard, paneling, or honeycomb wall
panels with expansion-type fasteners. The
fasteners can tear out and the air filter can
fall. Ignoring this caution can result in injury
or property damage.

To hang machine from ceiling:

1. Drill pilot hole for each ceiling hook in center

of joist at mounting location so these will align
with machine eye bolts.

Note: If ceiling joists are covered with sheet

rock or paneling, use a stud finder or other
device to locate joist centers.

2. Fully thread ceiling hooks into joists and
install (4) lengths of chain, cable, or steel
strapping from ceiling.

3. Thread (1) flange nut onto eye bolt, as shown
in Figure 14.

4. Thread eye bolt into top of machine, and
tighten flange nut against top to secure (see

To calculate the recirculating rate for your
shop space:

Performance

When used in conjunction with an efficient dust
collection system, the Model T33150 and T33151
remove most fine wood particles up to 0.3 microns
from the air. The air filters are capable of recircu­lating the air in a room measuring 25' x 25' x 8'
approximately the following number of times per
hour:

— T33150: 7.5 times at 620 CFM.
— T33151: 16.8 times at 1400 CFM.

We recommend that the volume of air in your
room be recirculated 6–8 times per hour for the
best filtering effect.

Therefore, rooms with a larger volume may require
two or more air filters to achieve proper filtering.

1. Calculate the volume of air in your shop by
multiplying the length x width x height of the
room (see the example below). Then, divide
the volume by the speed (CFM) you have
chosen to operate the air filter. This will give
you how many minutes it takes to recirculate
the air in the room.

Example: The room measures 25' x 25' x 8'

and you are operating the air filter at 1290
CFM (HI).

= =

2. Calculate how many times per hour the room
volume is recirculated through the air filter by
dividing 60 minutes by the circulating time from
Step 1. This will give you how many times
an hour the air in the room is recirculated
through the air filter.

SECTION 8: WIRING

stated in this manual, and study this section carefully.

If there are differences between your machine and what is shown in this section, call Technical Support at
[phone] for assistance BEFORE making any changes to the wiring on your machine. An updated
wiring diagram may be available. Note: Please gather the serial

Wiring Safety Instructions

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous.
Touching electrified parts will result in personal
injury including but not limited to severe burns,
electrocution, or death. Disconnect the power
from the machine before servicing electrical com­ponents!

MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpre­dictable results, including serious injury or fire.
This includes the installation of unapproved after­market parts.

WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires dis­connected or connected during any wiring task to
ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious per­sonal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.

MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.

CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.

EXPERIENCING DIFFICULTIES. If you are expe­riencing difficulties understanding the information
included in this section, contact our Technical
Support at [phone].
