Additional Safety Instructions For Air
Compressors
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.
4. Do not pull on rubber hoses to move the
compressor.
5. Do not use compressed air for filling breath-
ing 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 pres-
sure. Always make sure the pressure in the storage tanks has been released before loading or moving the air 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 your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equip-

110V Operation
SECTION 2: CIRCUIT REQUIREMENTS
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.
Extension Cords
Grounding
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.
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.
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.

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.

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 assis-
tance 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

Before using your Grizzly Air Compressor, follow these steps before the first use:
1. Remove all packing materials and the pro-
tective 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.
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.
NOTICE
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-

SECTION 4: OPERATIONS
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.
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.
General
Fig 3. Pressure safety relief valve.
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.

Switch
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.

After the compressor has fully pressurized the tanks, turn the red knob on the pressure regula-
tor (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.
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.
Starting

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.

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.

Cap.
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
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.
Each Use
Fig 7. Checking oil level with dipstick.

Fig 8. Typical location of drain cocks.
2. Drain tanks of any condensation by open-
ing 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.
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.
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.

Weekly
Every 300 Hours
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.
After every 300 hours or 3 months of regular operation, perform the following maintenance items:
1. Change compressor motor oil.
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.
After First 50 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).
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.
Fig 9. Air filter cover and foam element.
Page 16
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.
-14-
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.
Fig 10. Removing pressure switch cover.
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.
Fig 11. Adjusting nut on pressure switch.
Adjusting Nut
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.
