1. Operate the compressor in a well-ventilated
area free of acids, vapor, explosive gases
and flammable or unstable materials.
2. Use compressor only with air, never use
with any other type of gas.
3. Never aim the air nozzle directly at yourself
or others. The air stream can be quite forceful and can damage skin.
5. Do not use compressed air for filling breathing or diving apparatus. Compressed air
from this compressor cannot be used for
pharmaceutical, food or health requirements without further treatment.
6. Never transport the compressor under pressure. Always make sure the pressure in the
storage tanks has been released before
loading or moving the air compressor.
4. Do not pull on rubber hoses to move the
compressor.
7. Never attempt to adjust the pressure safety
valve on the air tanks. This is preset to 150
PSI.
Operating this equipment has the potential
to propel debris into the air which can
cause eye injury. Always wear safety glasses or goggles when operating equipment.
Everyday glasses or reading glasses only
have impact resistant lenses, they are not
safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards
Institute (ANSI).
Like all power tools, there is danger associated with the operation of air compressors. Accidents are frequently caused by
lack of familiarity or failure to pay attention.
Use this equipment with respect and caution to lessen the possibility of operator
injury. If normal safety precautions are
overlooked or ignored, serious personal
injury may occur.
No list of safety guidelines can be complete. Every shop environment is different.
Always consider safety first, as it applies to

SECTION 2: CIRCUIT REQUIREMENTS
110V Operation
Grounding
This family of air compressors is wired for
110/120V, single phase operation only. The chart
below shows the maximum amperage draw and
recommended fusing level for each of the
machines.
In the event of an electrical short, grounding
reduces the risk of electric shock by providing a
path of least resistance to disperse electric current. These machines are equipped with power
cords having an equipment-grounding conductor.
See Figure 1. The outlet must be properly
installed and grounded in accordance with all
local codes and ordinances.

It is generally best to operate a compressor on a
dedicated circuit, i.e. a circuit where there are no
other electrical appliances plugged in. The dual
motors on the G8299 should be plugged into separate circuits. The fuse requirements above
assume the use of a circuit breaker or a slowblow fuse. If an unusual load does not exist and
the compressor still breaks the circuit, 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 grounded. 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.
Extension Cords
If you find it necessary to use an extension cord
with your compressor, 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.

To operate this, or any power tool, safely
and efficiently, it is essential to become as
familiar with its characteristics as possible.
The time you invest before you begin to use
your air compressor will be time well spent.
DO NOT operate this machine until you are
completely familiar with the contents of this
manual. Make sure you read and understand all of the safety procedures. If you do
not understand something, DO NOT operate
the machine.
G8297/G8298/G8299 Air Compressors
Unpacking
This air compressor is shipped from the manufacturer in a carefully packed carton. If you discover the machine is damaged after you’ve
signed for delivery, and the truck and driver are
gone, you will need to file a freight claim with the
carrier. Save the containers and all packing materials for possible inspection by the carrier or its
agent. Without the packing materials, filing a
freight claim can be difficult. If you need assistance determining whether you need to file a
freight claim, or with the procedure to file one,
please contact our Customer Service.
When taking the air compressor to a job site, the
most important consideration is access to an
adequate and properly fused power supply. Refer
to Section 2: Circuit Requirements for the needs
for your particular compressor.
Also make sure the compressor is not operating
in an environment where there are any explosive,
flammable or caustic fumes or gases. A clear and
well-ventilated area is best for its safe operation.
Place the compressor on a solid and level surface. Make sure that the hoses you attach to supply your pneumatic device will be unrestricted in
movement and not subject to being run over by
vehicles or punctured by any other sharp objects
in the area.
And since air compressors are often used for a
sustained period of time, sometimes in restricted
areas, it is also best to wear ear protection to
avoid the long-term exposure to the sound of the
electric motor and piston.
NOTICE
The machine should always be run in the
positions shown on the cover of this manual. Never run the G8299 when it is standing
upright on its wheel and support frame.
Also never continue to operate the machine
if it has fallen over on its side. The motor
will not receive adequate oil flow in these
positions, and continued operation can

NOTICE
Before using your Grizzly Air Compressor, follow
these steps before the first use:
1. Remove all packing materials and the protective plastic plugs from the cylinder head
and oil plug. Do not remove the yellow cap
underneath the black plastic cover of the
pressure switch housing.
The machine should never be run without a
full oil reservoir. The oil provides lubrication to the cylinder rings which deliver the
compressed air. Severe damage to the
internal parts can occur if there is not adequate oil flow. Check the oil level frequently, and change the oil on a regular sched-
2. Screw the air filter(s) into the cylinder
head(s).
3. Place the oil dipstick into the opening of the
casing and check the oil level in the motor
crankcase. See Figure 2. Each motor
requires approximately 100 cc or 3.5 fluid
ounces of compressor oil (ISO 100 or SAE
30W viscosity, non-detergent). Make certain the oil is at the full indicator level on the
dipstick.
Operating this equipment has the potential
to propel debris into the air which can
cause eye injury. Always wear safety glasses or goggles when operating equipment.
Everyday glasses or reading glasses only
have impact resistant lenses, they are not
safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards
Institute (ANSI).
Operating this equipment has the potential
for hearing damage to occur, especially if
operated for a long period of time. Use
ANSI (American National Standards
Institute) approved ear muff or ear plugs
when using this equipment. Always wear
proper hearing protection, cotton balls or
tissue paper in the ear canal do not provide
adequate noise reduction.
Fig 2. Oil sump and dipstick.
4. Make sure drain valve(s) on the air tanks is
closed.
5. Make sure the power switch is in the OFF
position, fully pushed in. Connect the power
cord(s) to a properly protected power
source.

SECTION 4: OPERATIONS
General
The pump produces compressed air which goes
into the air tanks through the delivery pipe and
the check valve. When the air pressure arrives at
the factory pre-set level of 135 PSI, the pressure
switch shuts off the electrical current to the axial
electric pump. At the time it shuts off, it discharges the air held in the pump cylinder to the
delivery pipe. This allows the pump to be depressurized so it can easily restart. When the pressure in the air tanks falls below the minimum factory set pressure of 105 PSI, the pump cycles
again to build the pressure back up. The pressure
switch is supplied with a discharge valve with
delayed closing, which reduces the strain on the
pump and the motor during startup.
The compressor is operating correctly when there
is a bleed of air every time the motor is switched
off. You will notice an audible air discharge each
time the pump motor stops. On these compressors, the pump will cycle first to minimize the
amperage draw and will bleed off air through the
cold-start valve. The valve will stay open until
approximately 20 PSI is reached in the air tanks
at which time it closes to allow full pressurization
of the tanks.
For the G8299 with the dual motors, both motors
can be started simultaneously for rapid pressurization. As with the G8298, the 2.5 HP pump is fitted with a cold-start valve which will stay open
until approximately 20 PSI is reached in the
tanks. This will allow the compressor to lubricate
properly without straining the motor and pump.
All of the compressors are equipped with a 150
PSI safety relief valve which will discharge air
from the tanks if for any reason they should
become over-pressured. See Figure 3. These
are preset valves and are not adjustable.
Relief Valve
Fig 3. Pressure safety relief valve.
These compressors are also equipped with thermal overload breakers which will trip if there is
excessive load on the motors which causes a
heat buildup. In the event the breaker shuts the
compressor down, wait a few minutes for the unit
to cool down, then press the reset button shown
in Figure 4.

Depending on the volume of the air usage, it is
often adequate to recharge the system during
operation using only the 2 HP pump taking
advantage of its lower RPM and quieter operation.

Starting
Pressure Regulator
Make sure the compressor switch is in the OFF
position (the red button on top of the control box
should be in the fully depressed position, see
Figure 5) before connecting to the power supply.
Close the drain cock on the tanks. Pull the switch
to the ON position.
After the compressor has fully pressurized the
tanks, turn the red knob on the pressure regulator (See Figure 6) to set the pressure needed for
the air tool you will be using. Consult the manual
which accompanied your air tool to determine
what pressure setting is required for optimal operation. The gauge on the regulator will indicate the
pressure which will be delivered through the air
line.

Check the tank pressure gauge to see that the
tank pressure gets up to approximately 120-130
PSI.
Fig 6. Pressure regulator and gauge.
Always wear safety glasses and use
extreme caution when working around
compressed air. The force of the air stream
can cause small bits of debris to become
airborne and cause potential injury to the
eyes or other parts of the body. Never let
the full force of the air stream come in
direct contact with the skin as it can cause
abrasions or bruising.

G8297/G8298/G8299 Air Compressors
Connecting Tools
Notes
Make sure the compressor model you use has
sufficient cubic feet per minute (CFM) output for
the air tool you plan to connect. Most air tools will
have an air requirement stated in terms of a specific CFM at a specific pressure (PSI). Most common is a rating at 90 PSI. Consult the chart below
to determine the output of your compressor
model.

The compressor should put out a higher CFM
than the tool requires. If connecting multiple tools
which will be used simultaneously, then the CFM
for each tool should be added together and compared to the compressor output value.
Consideration should also be given to the type of
usage. A nailer or staple gun uses air in short
bursts and it is easier for the compressor to maintain pressure. A paint sprayer or grinder tends to
use a more continuous stream of air as these
tools are run for longer time periods. It is always
better to oversize a compressor to allow for variation in the type of usage and the number of tools
to be powered. Air tools being operated with
insufficient air volume will not perform their function satisfactorily.
Connect the tool using a good quality air line with
an adequate length to reach from the compressor
to the point of use. Quick-connect couplers are a
good option for fast and sure connection of tools
and air hoses. Make certain the air hose will not
be placed in a position where it can become constricted or cut by a sharp object. Having a hose
run over by heavy vehicles may not cause an
immediate leak, but it will shorten the life of the
hose.

SECTION 5: MAINTENANCE
Each Use
Regular periodic maintenance on your Air
Compressor will ensure its optimum performance. Make a habit of inspecting your compressor each time you use it. Check the following
items:
1. Check oil level. See Figure 7.
Fig 7. Checking oil level with dipstick.
2. Drain tanks of any condensation by opening the drain cocks on the bottom of both
tanks. See Figure 8. Depending upon the
amount of use and the weather conditions,
a certain amount of condensed water may
be released. For longevity of the compressor seals and the air tools you connect, it is
best to keep the tanks free of water. The
tanks are best drained if the drain cocks are
opened when the system is pressurized.
Once water has stopped coming out, you
can close the drain cocks.
-12-
Always wear safety glasses and use
extreme caution when working around
compressed air. The force of the air stream
can cause small bits of debris to become
airborne and cause potential injury to the
eyes or other parts of the body. Never let
the full force of the air stream come in
direct contact with the skin as it can cause
abrasions or bruising.
Fig 8. Typical location of drain cocks.
3. Clean off cylinder head cooling fins of any
dirt which might hamper air flow.
4. Check for worn or damaged cords and
plugs.
5. Check for any other condition that could
hamper the safe operation of this machine.
G8297/G8298/G8299 Air Compressors
After First 50 Hours
Every 300 Hours
After the first 50 working hours, or 30 days,
whichever comes first, replace the oil in the
motor with compressor oil (use ISO 100 or SAE
30W viscosity, non-detergent type).
After every 300 hours or 3 months of regular
operation, perform the following maintenance
items:
1. Change compressor motor oil.
Also after this initial operation period, check to
make sure that all the fittings are tight. Remove
the air filter foam element (See Figure 9) and
rinse it out in water. Allow it to dry and reinstall.
Blow out any accumulated dirt between the cylinder cooling fins.
2. Rinse the air filter foam element in water.
3. Check for air leaks and correct as needed.
4. Clean cylinder head fins for proper cooling.
5. Check for loose bolts or fittings.
Fig 9. Air filter cover and foam element.
Weekly
If the compressor is used on a regular daily basis,
perform the following checks each week:
1. Rinse the air filter foam element in water.
2. Check for loose bolts or fittings.

-13-
Pressure Limit
Adjustment
The compressor is delivered with pressure switch
settings which turn the compressor pump off
when it reaches a tank pressure of 135 PSI, and
turn it back on when it reaches 105 PSI. Normally
these settings should not require any adjustment.
In the event it becomes necessary to change, first
make certain the compressor is disconnected
from the power source. Then remove the black
plastic cover below the On/Off switch. This is
done by removing the rubber plug on top of the
housing and inserting a Phillips® screwdriver. See
Figure 10.
The hex nut on the top of the exposed switch is
used to adjust the pressure limits. See Figure 11.
Turn it clockwise to increase the pressure and
counterclockwise to reduce. This will move both
the maximum pressure shutoff point and the minimum pressure turn-on point simultaneously.
These limits are not separately adjustable. Do not
exceed a maximum cutoff pressure of 145 PSI.
After adjusting, replace the cover and reconnect
to the power source.
Adjusting Nut
Fig 11. Adjusting nut on pressure switch.
Fig 10. Removing pressure switch cover.
For the G8299, it is possible to control which
motor comes on first by adjusting these pressure
limits. The machine is set from the factory so the
2 HP pump comes on first to minimize amperage
draw. If this is not acceptable, adjust the limits on
the 2 HP higher, and set the limits on the 2.5 HP
lower so they will operate in reverse of the factory setting.
Do not remove the pressure switch cover
with the machine plugged in to power.
When the cover is off, the electrical connections are uncovered and can be a
source of electrical shock. Make the adjustments progressively until the desired level
is reached, and disconnect from power
each time you turn the adjusting nut.
Serious personal injury can occur.
