The motor supplied with the G9717 must be operated at 110V. Use an outlet configuration as
shown in
FFiigguurree 11..
Under normal use, the motor
draws approximately 2-3 amps @ 110V. We recommend a 15 amp circuit breaker for 110V operation. This should be satisfactory for normal use,
while providing enough protection against motor
damage caused by power surges.

Typical 110V plug and outlet.
Should it be necessary to use an extension when
operating at 110V, make sure the cord is rated
Hard Service (grade S) or better. Refer to the
chart in Section 1: Safety Instructions to determine the minimum gauge for the extension cord.
The extension cord must also contain a ground
wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

The Tool Rest provides a surface which can be
used to support the workpiece during grinding.
Certain types of grinding may require jigs or
accessories to assure the proper angle of the
piece against the wheel.
The Tool Rest assembles to the inboard side of
the Wheel Guard. Use two (2) hex bolts and lockwashers inserted through the rest support and
thread into the tapped holes. Repeat this installation for the opposite side wheel. The Tool Rest
can be adjusted in and out by loosening these
bolts. Always retighten before beginning grinding
operations.
EEyyee SShhiieelldd
The Eye Shield should be positioned between the
grinding wheel and the operator’s face during
grinding. This lessens the possibility for sparks or
metal bits to go flying directly at the operator.
The Eye Shield has a clear plastic panel which is
attached to a support bracket. Thread the long
Phillips
®
head screw through the bracket, then
through the shield, and then through the other
side of the bracket. Use a nut and lockwasher,
but leave it loose enough so the angle of the Eye
Shield can be adjusted.
Attach the support bracket to the top end of the
wheel rim guard with a Phillips
®
head screw, flat
washer and lockwasher into the tapped hole.
Note that there is a slot in the support bracket
which allow adjusting the Eye Shield up and
down.
Repeat the Eye Shield installation for the opposite side wheel.

The grinder base has two holes directly under the
wheel shaft. These holes can be used to mount
the grinder to a workbench, table top, or other
solid surface. Since grinding does develop a lot of
force, it is best to mount the grinder solidly before
using. If you wish for the grinder to remain
portable, it can be temporarily clamped to a table.
Just make certain no part of the clamping device
interferes with the wheels or the tool rests.

Once assembly has been completed, the G9717
Grinder is ready for use in the shop.
The switch is located on the front of the grinder.
To turn the grinder “ON”, push the right hand side
of the rocker switch, to turn it “OFF”, push the left
hand side of the switch. Always make sure the
wheels come up to full speed before introducing
the workpiece to the wheel.
When mounting a new wheel, or when there is
any concern about wheel integrity, stand away
from the line of rotation of the wheel and then turn
the wheel “ON”. If there is a potential problem it
will generally occur when the wheel is first started.
Aluminum oxide and silicon carbide wheels are
marked in a somewhat uniform manner by all the
major manufacturers. Understanding these markings will help you understand the capabilities of
various wheels. Always refer to the manufacturer’s grinding recommendations when selecting a
wheel for your project.
The basic format for wheel numbering is:
PPrreeffiixx AAbbrraassiivvee GGrriitt GGrraaddee BBoonndd
TTyyppee SSiizzee TTyyppee
3366 AA 6600 LL VV
The most common abrasive types used are A for
Aluminum Oxide and C for Silicon Carbide, and
occasionally SG for seeded gel. The prefix is the
manufacturer’s designation for a particular type.
The grit size is a number referring to the size of
the abrasive grain in the wheel. The lower the
number the coarser the wheel - 10 is a very
coarse wheel for roughing and 220 is usually the
upper range for fine finish work.
Grade is an indication of the hardness of the
wheel, with A being softest to Z the hardest.
Bond Type refers to the type of bonding material
used to hold the abrasive material. Most general
purpose wheels will have a V indicating Vitrified
clay is used, providing a high strength and good
porosity. The other most common is B for resin
where synthetic resins are used. These are used
to grind cemented carbide and ceramic materials
There may be other numbers inserted which
have meaning for a particular type of wheel.
Refer to the manufacturer’s technical data for a
complete explanation.

Before mounting any wheel, check it for integrity
by performing a “ring check”. Balance the wheel
on one finger, then lightly tap the rim of the wheel
with a piece of wood such as the handle of a
hammer. The wheel should have a ringing or
harmonic type of sound. If it responds with a dull
thud it may indicate that the wheel has cracks. Do
not use a wheel which is suspected of having
cracks, or if there are visual chips, nicks or dents
in the wheel surface. These discontinuities can
lead to wheel failure where the wheel flies apart
at operating speed. Always be sure to use a
wheel which is rated for operating at speeds
equal to or greater than 3450 RPM.
The wheel guard assembly must be removed in
order to mount or dismount a grinding wheel.

head screws
and nuts which go through the outer guard.

Use a
3
⁄4" or 19mm open end wrench on the
nut which holds the wheel on the arbor.
Hold the wheel from turning with the other
hand. Note that the wheel on the left hand
side of the machine is a left hand thread, so
loosening it will require turning it clockwise.
44
. Remove the outer wheel flange and the
paper disc.
55..
Pull the wheel free from the arbor. There
will also be a paper disc and a wheel flange
on the back side of the wheel. Always make
certain there is a paper or fiber disc
between the wheel flanges and the wheel
itself, this helps to spread the rotational
forces across the inner area of the wheel.
SSeeee FFiigguurree 55..
66..
Mount the new wheel in the reverse order.
First a wheel flange, a paper disc, the
wheel, a paper disc, a wheel flange and
finally the nut itself. Tighten the nut snugly
but do not over tighten. Over tightening can
crack the wheel.
77..
Run a new wheel for at least 1-2 minutes
while standing clear of the line of rotation.
If a wheel does have defects it will generally fail as soon as it gets up to full speed

The grinding wheel should be inspected before
every use. Use the ring check method noted in
the Grinding Wheel section in Operations to verify the structural integrity. If using coolant during
grinding, always run the wheel for 5-10 minutes
at the end of the operation to remove any coolant
from the wheel. Take care in storing grinding
wheels to keep them free from potential damage
by being dropped, or having other items drop on
them.
Replace the wheel when the wheel diameter is
reduced to 4". Operating at anything less than
this diameter does not allow the proper alignment
of the Tool Rest and the Eye Shield.
Depending on the type of grinding you do, the
grinding wheel may require periodic dressing.
There are several different types of wheel dressing devices available on the market. Use a suitable diamond or silicon carbide stick type dresser. Sweep it smoothly and evenly several times
across the face of the wheel. Dressing restores
the abrasive quality of the wheel surface, plus it
will bring the wheel edge back to a square form.
Refer to the instructions which accompany your
dressing accessory for complete detail on wheel
dressing.

The Model G9717 features factory-sealed bearings. A sealed bearing requires no lubrication
during its lifetime. Should a bearing fail, your
grinder will probably develop a noticeable rumble,
which will increase when the machine is put
under load. If the bad bearing is not replaced, it
will eventually seize - possibly doing damage to
other parts of the machine. Bearings are standard
sizes and can be replaced through Grizzly.
