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.
NOTICE - Alerts the user to useful information about proper operation of the 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, dis- connect 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. Always disconnect 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.
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 mate-rial. Always wear a NIOSH-approved respirator to reduce your risk.
SECTION 1: SAFETY
DANGER
Indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.
CAUTION
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.
WARNING
Indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury.

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!
Additional Safety for Blast Cabinets
PERSONAL PROTECTION EQUIPMENT. Media blasting presents a real hazard of silicosis and other lung contamination injuries!
These injuries are permanent and can get worse over time. If you use media blasting equipment without the proper hood, eye
protection, and respirator, your lungs and eyes may become permanently damaged. Protect yourself correctly, and keep all
unprotected bystanders away. For the latest types of protective equipment and acceptable respirator types, contact your local
OSHA or NIOSH office.
WORK AREA SAFETY. To prevent accidental contamination of shop air, clean dust collector and filters often, and repair any
suction hose leaks immediately.

MAINTAINING MACHINE. To prevent accidental contamination of shop air, check the blast cabinet for any leaks before use, and
reseal immediately.
AVOIDING ENTRAPMENT. To prevent an entrapment hazard for animals or children, always close and latch the blast cabinet
door when not in use.
LEAVING THE AREA. To prevent accidental blasting injury, disconnect air supply when leaving the blast cabinet.
MAINTAINING COMPONENTS. To prevent accidental contamination or blast injury, replace tips, hoses, lenses, and gloves when
they become worn.
SAFE MEDIA BLASTING. Do not use system over the rated PSI or lines and seals may burst and cause injury.
SAFE MAINTENANCE. To prevent accidental blasting injury or shock, disconnect air supply and power before loading and
unloading a workpiece, and before doing maintenance or changing blast tips.
SAFE ENVIRONMENT. To avoid media escaping from the cabinet, never use the blast cabinet if the dust collector is OFF or its
filter is clogged. If you do, media will exit through the cabinet air intake and enter the shop work environment. Always close and
latch the blast cabinet door shut before and after operation.
WARNING
Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity
or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety
precautions are overlooked or ignored, serious personal injury may occur.
CAUTION
No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to
your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious
personal injury, damage to equipment, or poor work results.

Availability
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.
Full-Load Current Rating
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.
Full-Load Current Rating at 110V...... 10.5 Amps
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 over- loading the machine during operation and make sure it is
connected to a power supply circuit that meets the specified circuit requirements.
Circuit Requirements
This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:
Nominal Voltage ......................................... 110V, 115V, 120V
Cycle.................................................................................... 60 Hz
Phase.................................................................... Single-Phase
Minimum Circuit Size................................................. 15 Amps
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.)
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.
SECTION 2: POWER SUPPLY
CAUTION
For your own safety and protection of property,
consult an electrician if you are unsure about wiring
practices or electrical codes in your area.
WARNING
Electrocution, fire, hock, or
equipment damage may occur
if machine is not properly
grounded and connected to
power supply.

Grounding & Plug Requirements
This machine is equipped with a power cord that has an equipment
-grounding wire and a grounding plug. Only insert plug into a matching
receptacle (outlet) that is properly installed and grounded in accordance
with all local codes and ordinances. DO NOT modify the provided plug!
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.
Extension Cords
We do not recommend using an extension cord with this machine.
If you must use an extension cord, only use it if absolutely necessary
and only on a temporary basis.
Extension cords cause voltage drop, which can damage electrical
components and shorten motor life. Voltage drop increases as the
extension cord size gets longer and the gauge size gets smaller (higher
gauge numbers indicate smaller sizes).
Any extension cord used with this machine must be in good condition and
contain a ground wire and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size ...........................14 AWG
Maximum Length (Shorter is Better).......50 ft.
WARNING
Serious injury could occur if you connect machine to
power before completing setup process. DO NOT
connect to power until instructed later in this
manual.
CAUTION
SHOCK HAZARD!
Two-prong outlets do not meet the grounding
Requirements for this machine. Do not modify or
use an adapter on the plug provided—if it will not fit
the outlet, have a qualified electrician install the
proper outlet with a verified ground.
