SECTION 2: CIRCUIT REQUIREMENTS  
Grounding  
110V Operation  
In the event of an electrical short, grounding  
reduces the risk of electric shock by providing a  
path of least resistance to disperse electric cur-  
rent. This tool is equipped with a power cord hav-  
ing an equipment-grounding conductor. See  
Figure 1. The outlet must be properly installed  
and grounded in accordance with all local codes  
and ordinances.  
The Model G8220 is wired for 110V, single phase  
operation only. The 14 HP motor will draw 1 amp  
at 110V. If you operate this grinder on any circuit  
that is already close to its capacity, it might blow  
a fuse or trip a circuit breaker. However, if an  
unusual load does not exist and a power failure  
still occurs, contact a qualified electrician or our  
service department.  
This equipment must be grounded. Verify  
that any existing electrical outlet and circuit  
you intend to plug into is actually ground-  
ed. If it is not, it will be necessary to run a  
separate 12 A.W.G. copper grounding wire  
from the outlet to a known ground. Under  
no circumstances should the grounding pin  
from any three-pronged plug be removed.  
Serious injury may occur.  
Fusing  
A 15-amp fuse or circuit breaker should be used  
when connecting this Bench Grinder. Circuits  
rated any higher are not adequate to protect the  
motor from power surges.  
Equipment returned to us for service that shows  
evidence of being over-fused will be repaired or  
replaced totally at the customer’s expense,  
regardless of the present warranty status.  
Extension Cords  
If you find it necessary to use an extension cord  
with the Model G8220, make sure the cord is  
rated Hard Service (grade S) or better. Refer to  
the chart in the standard 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.

Site Considerations  
Notes  
BENCH MOUNTING  
Your G8220 Wet/Dry Grinder is designed to be  
used on a workbench. Make sure it is positioned  
at a comfortable working height. The machine  
can be permanently mounted to a bench by  
removing the base and using the four holes in the  
motor body to secure it directly to the surface of  
a bench.  
WORKING CLEARANCES  
Working clearances can be thought of as the dis-  
tances between machines and obstacles that  
allow safe operation of every machine without  
limitation. Ensure that your working area offers  
plenty of room for free movement and a substan-  
tial amount of distance between you and others  
that may be working in your shop space.  
LIGHTING AND OUTLETS  
Lighting should be bright enough to eliminate  
shadow and prevent eye strain. Electrical circuits  
should be dedicated or large enough to handle  
combined motor amp loads. Outlets should be  
located near each machine so power or exten-  
sion cords are not obstructing high-traffic areas.  
Be sure to observe local electrical codes for prop-  
er installation of new lighting, outlets, or circuits.  
Make your shop “child safe”. Ensure that  
your workplace is inaccessible to young-  
sters by closing and locking all entrances  
when you are away. Never allow visitors in  
your shop when assembling, adjusting or  
operating equipment.

2. Thread a locking knob with washer through  
the hole in the bottom of the holder and into  
the water tray body. These knobs control  
the overall height of the tool rest assembly.  
Tool Rest-Wet Wheel  
The large horizontally mounted wet grinding  
wheel also has a tool rest situated over it to aid  
the user in the grinding operations:  
3. Set the tool rest into the half circle recess-  
es. The sliding tool rest should already be  
assembled onto the holder, if it is not, slide  
the tool rest into the groove. It only goes  
one way as there is a tab preventing incor-  
rect installation. The miter gauge also  
should already be positioned on the sliding  
tool rest.  
1. Position the two support brackets in the  
wide grooves which are located on each  
side of the water tray. The recess in the  
shape of a half circle should be facing out-  
ward on each side. See Figure 4.  
4. Attach the tool rest assembly to the support  
brackets. Using the M4-.7 x 30mm Hex  
Head Bolt, push the bolt through from the  
inside of the holder and secure a knob to it  
on the outside. See Figure 5. These two  
knobs control the angular adjustment of the  
tool rest. The hex heads will lock into a  
recess molded into the inside of the brack-  
et.

SECTION 5: Operations  
Overview  
Use extreme caution when sharpening any  
type of knife, both during and after sharp-  
ening. Make certain the knife is fully sup-  
ported by the rest before bringing it into  
contact with the wheel. Failure to exercise  
care while working near knives could result  
in severe injury.  
The dry wheel supplied with the G8220 is an 80  
grit Aluminum Oxide wheel good for heavy mate-  
rial removal and for roughing in to approximate  
dimensions. The wet wheel is a very fine 1000  
grit which, along with the water supply, allows  
fine grinding and honing to very precise edges.  
Choose the wheel and grinding method appro-  
priate for your grinding needs.  
Figure 6. Typical wet wheel grinding operation.  
naturally generated during the grinding process.  
Secondly, the water acts as a lubricant for the  
grinding process improving the cutting character-  
istics of the fine grit wheel. As you begin grinding,  
adjust the water flow so there is a steady drip  
onto the surface of the wheel, close to the inner  
edge. Make sure the drain pipe coming out the  
underside of the water tray is directed so it is  
going into some type of container.  
Plug the machine in and turn the motor on. Allow  
the wheel to get up to full operating speed before  
beginning the grind. Introduce the item to the  
wheel slowly and carefully, making sure it is fully  
supported against the tool rest and miter gauge.  
For some types of grinds, it may be necessary to  
sweep the item across the wheel surface by slid-  
ing the tool rest across the holder. Always lift the  
item off the surface when returning to the starting  
point of the sweep. Do not let the workpiece get  
too hot during grinding. If heat is increasing, slow  
down the rate of grind, or turn up the water flow.  
High heat will destroy the temper of the metal  
and will make it impossible to hold an edge.  
Wet Wheel Grinding  
There are three adjustments necessary to get the  
proper grinding angle. Tool rest height, tool rest  
angle, and miter gauge angle must all be adjust-  
ed to get the proper angle of attack on the grind-  
ing wheel. Be sure the machine is off and  
unplugged. Lay the item to be ground on the rest  
and lay it against the stationary wheel. Adjust all  
three elements until the blade contacts the wheel  
in the proper orientation. A typical set up for a  
bevel tip chisel is shown in Figure 6.  
The water reservoir allows the operator to drip  
water onto the wheel during the grinding process.  
The water serves two purposes. One is to provide  
a certain amount of cooling for the heat which is

Long straight types of blades such as jointer or  
planer knives can also be sharpened on this  
machine as well. Position the blades as shown in  
Figure 7, with the miter gauge set at a zero  
angle. For this type of operation, it is necessary  
to sweep the blade edge across the wheel. The  
sliding table retained in the groove of the tool  
rest holder allows for this sweeping action. Allow  
the blade edge to push the circular foam materi-  
al down, this is perfectly acceptable and helps to  
insure the water does not spin off the wheel.  
Dry Wheel Grinding  
Adjust the angle of the Tool Rest by loosening  
the two lock knobs. The angle can also be affect-  
ed by raising or lowering the entire Tool Rest  
assembly by loosening the hex bolt at the front of  
the wheel guard. Once you have achieved the  
angle necessary for the item to be ground, make  
certain all the adjustment knobs and bolts are  
tightened so the rest will not move during grind-  
ing.  
Maintain a constant and steady pressure  
throughout the entire range of the sweeping  
action to ensure that the blade is evenly ground  
all the way to its edges. Be sure to avoid over-  
heating the blades during grinding.  
Position the Eye Shield so it will cover the grind-  
ing area. The Eye Shield can be moved up and  
down, as well as back and forth, to get it in a  
position where sparks will not fly up in the oper-  
ator’s face. Tighten the adjusting bolt.  
For dry grinding, it may be helpful to have a tray  
of water handy for quenching the piece when it  
builds up heat in the grinding process. Similar to  
the wet wheel process, quenching keeps the  
ground item from losing its temper by keeping  
the temperature down.  
Turn the grinder on and allow the wheel to come  
up to full speed. Place the item to be ground  
firmly on the Tool Rest and introduce it slowly  
into the wheel. Grinding should be done lightly  
and for short duration to avoid damage to the  
tool you’re working with.  
Sweep back  
and forth  
Figure 7. Grinding long knives.  
Use extreme caution when working near  
rotating grinding wheels. Accidental con-  
tact with the wheel can cause cuts and  
abrasions. The spinning wheels can also  
propel items which are not firmly support-  
ed. Failure to exercise care while working  
near grinding wheels could result in severe  
injury.
