This manual provides critical safety instructions on the proper setup, operation, maintenance, and service of this machine/tool. Save this document, refer to it often, and use it to instruct other operators.

Failure to read, understand and follow the instructions in this manual may result in fire or serious personal injury—including amputation, electrocution, or death.

The owner of this machine/tool is solely responsible for its safe use. This responsibility includes but is not limited to proper installation in a safe environment, personnel training and usage authorization, proper inspection and maintenance, manual availability and comprehension, application of safety devices, cutting/sanding/grinding tool integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, 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 specially designed to filter out microscopic particles.

ELECTRICAL EQUIPMENT INJURY RISKS. You can

be shocked, burned, or killed by touching live

machinery. To reduce this risk, only allow an electrician or 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 eliminates the risk of injury 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.

malfunction, leading to serious personal injury

from heated surfaces, high traffic areas, harsh

clothing, apparel, or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to avoid accidental slips, which could cause loss of workpiece control.

DUST. Dust created while using

machinery 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.

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

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

USE RECOMMENDED ACCESSORIES. Consult

this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase 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

CHECK DAMAGED PARTS. Regularly inspect

machine for any condition that may affect safe operation. Immediately repair or replace damaged or mis-adjusted parts before operating machine.

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, resulting in a short. Do not handle cord/plug with wet hands. Avoid cord damage by keeping it away

Additional Safety for Benchtop Grinders

Serious injury or death can occur from impact injuries if a grinding wheel breaks apart during operation. Rotating grinding wheels can easily remove skin or cause entanglement injuries if clothing or apparel is caught in moving parts. Fingers can be pinched/cut by in-running pinch points. Flying sparks can ignite explosive or flammable materials. To minimize risk of injury or death, anyone operating machine MUST completely heed hazards and warnings below.

SAFE MOUNTING & WORK AREA. An unsecured

SAFETY

grinder may become dangerously out of control during operation. Before use, verify grinder is FIRMLY secured in a location free of explosive or flammable materials.

STARTING GRINDER. If a wheel is damaged, it

will usually fly apart shortly after start-up. To protect yourself, always stand to side of grinder when turning it ON and allow it to run for at least one minute before standing in front of it.

VISUAL INSPECTION. Verify that grinding wheels

are free of cracks, chips, or dents in wheel surface before installing. Do not use wheel if it has any of these problems or it could break apart during operation.

WHEEL SPEED RATING. Before mounting a new

wheel, be sure wheel RPM rating is equal to or higher than speed of grinder. Never use unmarked wheels or wheels rated for lower RPM than grinder.

VIBRATING WHEEL. Never use a wheel that

vibrates excessively. Replace wheel or shaft bearings immediately.

SPARK DEFLECTOR GAP. Never allow gap

between end of spark deflector and grinding wheel to exceed gap is larger, additional sparks and abrasives will be expelled toward the operator, which will increase the risk of injury.

TOOL REST POSITION. A large distance (gap)

between tool rest and wheel increases risk of workpiece being pinched between wheel and tool rest causing wheel breakage, loss of control, and possible injury. Never allow gap between tool rest and wheel to exceed

⁄8”. Replace grinding wheel when tool rest

gap becomes wider than adjustment can be made to tool rest.

⁄4”. If the

⁄8″ and no additional

SIDE & TOP GRINDING. Grinding on side of

wheels can cause them to crack and burst— unless wheel is rated for side grinding. Grinding on top of wheels greatly increases risk of workpiece kickback. Always grind on downward part of wheel.

SPINDLE NUT. Only tighten wheel spindle nut

enough to drive wheel and prevent slippage.

EYE SHIELDS. Place eye shields close to grinding

wheel and re-adjust as wheel wears down.

HAND & WHEEL CONTACT. Keep a firm grip

on workpiece and position your hands a safe distance away when grinding. Anticipate when workpiece will heat up, and cool it before it becomes too hot to hold, or use an appropriate clamp. Avoid wearing gloves as they may get caught in grinding wheel and cause even more serious entanglement injuries.

WHEEL FLANGES. Only use flanges included with

or designed for this grinder when mounting wheels. Other flanges may not properly secure wheel and cause an accident. Do not use warped or damaged flanges, and always use paper discs (blotters) between wheels and flanges to reduce risk of flanges cracking wheel when tightening.

EYE, FACE, & LUNG PROTECTION. Grinding

ejects small particles at a high rate of speed. These particles can cause blindness, skin injuries or respiratory damage. ALWAYS wear approved clothing, safety goggles, face shield, and a respirator for type of grinding to be done.

RING TEST. Perform a “ring test” on grinding

wheels before installation to ensure they are safe to use. A wheel that does NOT pass ring test may break or fly apart during operation.
