Resumen del manual
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 -7 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. 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 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. 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. 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. -8 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. 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. G8297/G8298/G8299 Air Compressors 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 eve...
