WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead-based paints. • Crystalline silica from bricks, cement, and other masonry products. • Arsenic and chromium from chemically treated lumber. Your risk from these exposures varies, depending on how often you do this type of work.
SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
Safety Instructions For Pneumatic Tools 10. USE PROPER AIR HOSE for the tool. Make sure your air hose is in good condition and is long enough to reach your work without stretching. 11. WEAR PROPER APPAREL. DO NOT wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear a protective hair covering to contain long hair. 12. ALWAYS USE SAFETY GLASSES. Also use a face or dust mask if cutting operation is dusty.
Additional Safety For Air Compressors 1. 2. 3. 4. 5. 6. READ THIS ENTIRE MANUAL BEFORE OPERATING THE COMPRESSOR. OPERATE THE COMPRESSOR IN A WELL VENTILATED AREA free of acids, vapor, explosive gases and flammable or unstable materials. DO NOT PULL ON THE GAUGES OR REGULATORS TO MOVE THE COMPRESSOR! DO NOT USE THE COMPRESSOR FOR FILLING BREATHING OR DIVING APPARATUS. Compressed air from this compressor cannot be used for pharmaceutical, food or health requirements without further treatment.
INTRODUCTION AND SET UP Commentary We are proud to offer the Grizzly Models H4517 and H4518 Pancake and Hot Dog Air Compressors. These models are part of a growing Grizzly family of fine power tools. When used according to the guidelines set forth in this manual, you can expect years of trouble-free, enjoyable operation and proof of Grizzly’s commitment to customer satisfaction. The Model H4517 features a 2.5 HP motor, a cast-iron direct-drive pump, a 4 gallon tank capacity that delivers 4.
Unpacking Site Placement This air compressor is shipped from the manufacturer in a carefully packed carton. If you discover the machine is damaged after you have 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.
CIRCUIT REQUIREMENTS 110V Operation Grounding The Model H4517/H4518 Air Compressor is wired for 110V, single-phase operation only. The maximum amperage draw for the machine is 17 amps, with a fusing level rating of 20 amps. 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.
PREPARING FOR USE Before using your Grizzly Compressor, follow these steps: 1. 2. Air Remove all packing materials and any protective plastic bags, zip tie labels or tags from the compressor. Be sure the air filter is attached to the cylinder head as shown in Figure 2. 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.
STARTING To start the air compressor: 1. Make sure the compressor switch is in the OFF position (lever with red cap above pressure gauges shown in Figure 4) before connecting to the power supply. Figure 4. ON/OFF lever. 2. Close the drain valve, shown in Figure 5, so the tank can build up pressure. Check the pressure gauge to see that the tank pressure climbs to approximately 100115 PSI or around 8 BAR, then automatically turns off.
AIR CONTROL Delivered Pressure Air Release The tank pressure is displayed on the left pressure gauge, and the air to be delivered to the tool is displayed on the right pressure gauge, shown in Figure 6. There are two ways to release air from the compressor tank other than through your regulator and the use of air tools: —The drain valve —The safety drain valve To release air by using the drain valve, you simply turn the release nut to allow air to flow out of the tank.
Tank Pressure Regulator The pressure regulator has been factory set for the highest quality operating performance. The pressure regulator ensures the pump will shut off when the correct PSI is reached for the air compressor tank. To adjust the pressure regulator: 1. Unplug the air compressor from the power supply. 2. Make sure the compressor switch is in the OFF position. 3. Drain the pressure from the tank. 4.
CONNECTING TOOLS To connect air tools to your air compressor: 1. Make sure the compressor model you use has a 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.) 2. The compressor should put out a higher CFM than the tool requires. Consideration should also be given to the type of usage.
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! Use the sight gauge on the bottom of the crankcase to make sure the oil level is at the proper height. 2. Drain tanks daily of any condensation by opening the drain valve on the bottom of the tank and leave open until the next time it is used.
After First 50 Hours of Use Weekly After the first 50 working hours or 30 days, whichever comes first, the following maintenance should be done. If the compressor is used on a daily basis, perform the following checks each week. 1. Replace the oil in the crankcase with compressor oil or use ISO 100 or SAE 30W viscosity, non detergent type oil. 2. Check to make sure that all the fittings are tight. 3. Remove the air filter foam element shown in Figure 11 and rinse it out with water.
Every 300 Hours Storage After every 300 hours or 3 months of regular operation, perform the following maintenance items: When storing your air compressor, follow these guidelines: 1. Set the compressor switch lever to OFF. Rinse the air filter foam element in water. 2. Turn the regulator counter-clockwise to set the delivery pressure to zero. 3. Check for air leaks and correct as needed. 3. Remove the air tool or accessory. 4. 4. Clean the cylinder head fins for proper cooling.
TROUBLESHOOTING PROBLEM CAUSE ACTION Pump motor will not start 1. Low voltage. 2. Open circuit in motor, switch or cord. 3. Tank already pressurized. 4. Thermal overload switch. 1. Check power line for proper voltage. 2. Inspect all lead connections on motor, switch and cord for loose or open connections. 3. Motor will not start if tank pressure is too high. 4. Thermal overload switch has tripped, wait for motor to cool, then reset switch by pressing red button.
PROBLEM CAUSE ACTION Motor runs hot 3. Compressor is exceeding its dutycycle. 3. Do not allow the compressor to run over its recommended duty cycle. Pressure relief valve stays open and motor won’t stop running. 1. Faulty pressure switch, unit is trying to overpressure the tank. 2. Faulty pressure relief valve. 1. Turn compressor off, unplug from power supply, drain tank. DO NOT USE until switch is repaired or replaced. 2.
