Machine Description

This 6 x 18" Surface Grinder allows you to resur­face metal workpieces to create high-tolerance
flat surfaces. It utilizes a table that moves horizon­tally and a grinding wheel that moves vertically. By
mounting a workpiece to the table, then moving
the table and the grinding wheel during the grind­ing process, extremely small amounts of material
can be removed with each pass.

The G0763 is equipped with X- and Y-axis power
feeds that provide automated operation. In addi­tion to the convenient front-mounted controls
and handwheels, the G0763 includes a magnetic
chuck, recycling flood coolant system, halogen
work light, and one-shot oiler for lubrication of
sliding parts.

For grinding wheel maintenance, the G0763
includes a wheel-balancing tool and a diamond
dresser.

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 avoid
accidental slips, which could cause loss of work­piece control.

HAZARDOUS 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.

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.

Additional Safety for Surface Grinders

WHEEL SPEED RATING. Wheels operated at a

faster speed than rated for may break or fly apart.
Before mounting a new wheel, be sure the wheel
RPM rating is equal or higher than the speed of
the grinder.

WHEEL FLANGES. Only use the flanges included
with the grinder when mounting wheels. Other
flanges may not properly secure the wheel and
could cause the wheel to fly off or break apart.

RING T EST. Perform a "ring test" on grinding
wheels before installation to ensure that they are
safe to use. A wheel that does not pass the ring
test may break or fly apart during operation.

STARTING GRINDER. If a wheel IS damaged, it
will usually fly apart shortly after start-up. To pro­tect yourself, always stand away from the grinding
wheel when turning the machine ON and allow the
wheel to gain full speed before standing in front of
it.

CRACKED WHEEL. Cracked wheels may break
and fly apart during operation. Replace cracked
wheels immediately!

PROTECTIVE CLOTHING. Protect skin from fly­ing sparks by wearing close-fitting long sleeves
and buttoned-up shirt. In case of falling heavy
objects, wear leather, non-skid boots with added
toe protection.

GRINDING MAGNESIUM. Grinding material with
magnesium content may increase the risk of fire
or explosion. Before grinding material with magne­sium content, review all available safety informa­tion that pertains to grinding magnesium, including
the National Fire Protection Association standard
NFPA 480, “Storage, Handling and Processing
Magnesium.”

WORKPIECE CONTACT. A heavy impact
against the grinding wheel can cause it to break
or fly apart, causing serious personal injuries.
Avoid jamming the workpiece into the wheel to
reduce this risk.

LUNG PROTECTION. Grinding produces haz­ardous dust, which may cause long-term respira­tory problems if breathed. Always wear a NIOSH
approved dust mask or respirator when grinding,
and use coolant when possible to minimize this
risk.

HAND/WHEEL CONTACT. Grinding wheels
have the capability of removing a lot of skin fast.
Make sure the workpiece is securely clamped to
the table, then position your hands a safe dis­tance away when grinding. Avoid wearing gloves
as they may get caught in the grinding wheel and
cause even more serious entanglement injuries.

DUST COLLECTION. DO NOT connect a sur­face grinder to a dust collection system that is
used with woodworking machines. Sparks emit­ted from the grinding process may ignite wood
particles, resulting in fire or explosion. Only use
a metal-specific dust collection system with this
machine.

COOLANT USAGE. Use the correct personal
protection equipment when handling coolant.
Follow federal, state, and fluid manufacturer
requirements for proper disposal.

EYE PROTECTION. Grinding causes small par­ticles to become airborne at a high rate of speed.
ALWAYS wear ANSI-approved eye and face pro­tection when using this machine.

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 electrican or
qualified service personnel in accordance with all
applicable codes and standards.

Electrocution, fire, or
equipment damage may
occur if machine is not
correctly grounded and
connected to the 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 requirements in the following section.

This machine is prewired to operate on a 220V
power supply circuit that has a verified ground and
meets the following requirements:

For your own safety and protection of

Note: The circuit requirements listed in this man­ual apply to a dedicated circuit—where only one
machine will be running at a time. If this machine
will be connected to a shared circuit where mul­tiple machines will be running at the same time,
consult a qualified electrician to ensure that the
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.)

cord, only use it if absolutely necessary and only
on a temporary basis.

Extension cords cause voltage drop, which may
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
contain a ground wire, match the required plug
and receptacle, and meet the following require­ments:

Grounding Instructions

This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.

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.

Serious injury could occur if you connect

The power cord and plug specified under “Circuit
Requirements for 220V”
has an equipment-grounding wire and a ground­ing prong. The plug must only be inserted into
a matching receptacle (outlet) that is properly
installed and grounded in accordance with all
local codes and ordinances (see figure below).

No adapter should be used with the
required plug. If the plug does not fit the
available receptacle, or the machine must

The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.

Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.

There are many ways to remove this rust preven­tative, but the following steps work well in a wide
variety of situations. Always follow the manufac­turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.

Before cleaning, gather the following:

• Disposable rags

• Cleaner/degreaser (WD•40 works well)

• Safety glasses & disposable gloves

• Plastic paint scraper (optional)

Basic steps for removing rust preventative:

Site Considerations

Weight Load

Physical Environment

Place this machine near an existing power source.

Shadows, glare, or strobe effects that may distract

Refer to the Machine Data Sheet for the weight
of your machine. Make sure that the surface upon
which the machine is placed will bear the weight
of the machine, additional equipment that may be
installed on the machine, and the heaviest work­piece that will be used. Additionally, consider the
weight of the operator and any dynamic loading
that may occur when operating the machine.

Space Allocation

Consider the largest size of workpiece that will
be processed through this machine and provide
enough space around the machine for adequate
operator material handling or the installation of
auxiliary equipment. With permanent installations,
leave enough space around the machine to open
or remove doors/covers as required by the main­tenance and service described in this manual.

See below for required space allocation.

Children or untrained people
may be seriously injured by
this machine. Only install in an
access restricted location.

The physical environment where the machine is
operated is important for safe operation and lon­gevity of machine components. For best results,
operate this machine in a dry environment that is
free from excessive moisture, hazardous chemi­cals, airborne abrasives, or extreme conditions.
Extreme conditions for this type of machinery are
generally those where the ambient temperature
range exceeds 41°–104°F; the relative humidity
range exceeds 20–95% (non-condensing); or the
environment is subject to vibration, shocks, or
bumps.

Electrical Installation

Make sure all power cords are protected from
traffic, material handling, moisture, chemicals,
or other hazards. Make sure to leave access to
a means of disconnecting the power source or
engaging a lockout/tagout device, if required.

Lighting

Lighting around the machine must be adequate
enough that operations can be performed safely.

or impede the operator must be eliminated.

HEAVY LIF T!
Straining or crushing injury
may occur from improperly
lifting machine or some of
its parts. To reduce this risk,

5. Disconnect coolant hose from stand pipe

shown in Figure 12.

and use a fork lift (or other
lifting equipment) rated for
weight of this machine.

Lifting and placing the G0763 will require help
from at least one other person, a fork lift with
four safety hooks and chains (rated for 2500 lbs.
each), and a precision level.

To lift and place the machine:

1. Remove top crate from shipping pallet.

2. Remove loosely packed items from shipping

pallet.

3. Move pallet and machine to selected posi­tion.

4. Disconnect coolant power cable from electri­cal cabinet (see Figure 11) by twisting the
knurled ring counterclockwise (the ring clos­est to the electrical cabinet).

Stand

Pipe

6. Set coolant tank assembly aside.

7. Attach a handle to Y-axis handwheel, then

move saddle as close to column as possible.

8. Unbolt machine from shipping pallet.

9. Secure a safety hook and chain to each of

four lifting studs (see Figure 13 for identifica­tion).

Note: Place padding between chains and

machine to prevent scratching machine.

To assemble the surface grinder:

1. Install handles on X- and Z-axis handwheels.

2. Remove table restraints.

Take care not to damage table or saddle
ways. Any damage to these surfaces will be
permanent and result in poor finishes.

3. With help from another person, remove table

and place it upside down on a clean, flat sur­face.

4. Store plastic shipping rods (see Figure 15) for
future use when storing or moving machine to
protect ways.

Figure 14. Leveling pad and bolt installed.

12. Position leveling pads underneath bolts and

lower machine so the bolts rest in center of
pads.

For accurate results and to prevent warping
the cast iron ways, the table MUST be level
from side to side and from front to back.

Recheck the ways 24 hours after installation,
two weeks after that, and then annually to
make sure they remain level.

13. Using a precision level on unpainted table

surface without magnetic chuck, adjust level­ing pad bolts until table is level from side to
side and front to back.

14. When table is properly leveled, tighten down
hex nuts on bolts to secure settings.
