Instruction Manual For Belt Grinder-Buffer

Model 602E-MT

SAFETY NOTICE

: WARNING statements describe conditions that may lead to personnel injury including

potentially fatal injuries if the machine is not properly used and warnings are not properly
followed.

Caution statements describe conditions that may lead to equipment damage.

WARNING: Do not operate this grinder-buffer until you are sure that you are completely familiar with

the safe operation of the grinder-buffer, all accessories and safety equipment. Improper
use can lead to severe injury. This manual defines proper use of this equipment.
Before using this equipment for any other use, please seek expert advise if you do not
understand any procedure or operation concerning this grinder-buffer or this manual.

WARNING: Prevent electrical shock hazard and accidental machine operation. Always disconnect

grinder-buffer from the power source before servicing, changing accessories (such as
belt, wire wheel, tool rest, spark arrestor, etc.) or before performing maintenance.

WARNING: Avoid accidental starting. Make sure switch is in “OFF” position before connecting to

power source.

WARNING: Be sure the system is properly grounded before applying power. Do not apply power

before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. Follow the National Electrical Code (NEC) and local codes for the safe installation
of this equipment.

WARNING: Always use safety glasses with side shields (or full face shield) when operating grinder.

Do not use ordinary eyeglasses. Also use face or dust mask if cutting operation is dusty.

WARNING: Unsuitable accessories or attachments added to this machine can create hazards. Baldor

accessories are specifically designed to be used with this grinder-buffer. Use
accessories or attachments only in the proper intended manner. Accessories or
attachments obtained from another source may cause hazards. Consult the manufacturer
before use.

WARNING: To prevent injury, avoid contact with the wire wheel or belt or disc. The abrasive belt when

running is an aggressive cutting tool. Extra care should be exercised when using coarse grit
belts because of their rapid cutting action. Severe burns or cuts may result from contact.

WARNING: Keep guards in place and in working order. Guards are design to prevent injury. Never

operate this equipment if a guard is damaged, missing or improperly installed.

WARNING: Remove adjusting keys and wrenches from this product after use. Check to see that keys

and adjusting wrenches are removed from grinder-buffer before turning it on. Projectiles
can cause severe injury to yourself or others.

WARNING: Keep work area clean and well lighted. Clutter and poor lighting invites accidents.

WARNING: Don't use in dangerous environment. Don't use grinder-buffers in damp or wet locations,

or expose them to rain. Electrical shock can cause serious or fatal injury. Follow the
National Electrical Code (NEC) and local codes for the safe installation of this equipment.

WARNING: Do not wear loose clothing, neckties, rings, bracelets, or other jewelry to get caught in

moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain
long hair.

WARNING: Secure work. Use clamps to secure the work piece when practical. It's safer than using

your hand and it keeps hands away from wheel or belt.

WARNING: Check for damaged parts. Before further use, a guard or other part that is damaged should

be carefully checked to assure that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced.

SAFETY NOTICE

WARNING: When starting a grinder for the first time, or after installing a replacement belt or wire

wheel, it is most important that the operator stand aside for at least one minute of rotation
at full speed. This is the correct practice since a wire wheel can disintegrate if it received
damage during shipping or handling.

WARNING: Use proper grounded extension cord. Make sure your extension cord is in good condition.

When using an extension cord, be sure it is rated for the voltage and current rating of your
product. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. Use the correct wire size depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller the AWG gauge number, the heavier
the cord.

WARNING: Always wear a dust mask to prevent dust inhalation when adequate ventilation or extraction

is not available.

WARNING: Dust created during grinding, buffing, sawing, power sanding, drilling, and other activities

may contain chemicals known to the State of California to cause cancer, birth defects or
other reproductive harm.

WARNING: Keep children and visitors away. Remove starter keys turn off master switches. Padlock

equipment or work area when not in use.

WARNING: Don't over reach. Keep proper footing and balance at all times. A rotating wheel can catch

an article of clothing and cause personnel injury.

WARNING: Never leave grinder-buffer running unattended. Always turn power off after use.

Caution: Don't force grinder-buffer. It will do the job better and safer at the feed rate for which it

was designed.

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

Caution: Maintain grinder-buffer with care. Keep grinder-buffer clean for best and safest

performance.

Overview

Belt grinding or finishing has many advantages over the use of conventional grinding wheels.
It is possible to remove material up to 5 times faster than the equivalent grade of grinding
wheel with far less heat. The electrostatic process used in the manufacture of an abrasive
belt ensures that the sharp side of each piece of grit is facing outwards on the belt thus giving
cleaner, smoother and faster cutting. The flexing of the belt has a self cleaning action and
also it does not overheat, making it more suitable to any application where heat could
damage the work, for example, grinding leather, plastics, tool sharpening etc.
Select the correct belt for the application, see Table 2.

Disc grinding is a very useful and versatile part of the attachment. It is very useful for dressing
small castings and components, patterns, models, etc., often eliminating costly machining.
