cause the sand to cake and clog the gun, rendering it ineffective. the air line (MP3105), located as near to the gun as possible, eliminate this moisture. 4. Attach chuck or other tool to open end of hose. The compressor is now ready to use. The switch should be in the OFF position when connecting or disconnecting the power cord from the electrical outlet. REGULATOR 1. This regulator controls air pressure to the hose and attachment. 2. Turning knob clockwise increases air pressure at outlet. 3. Turning counterclockwise will lower air pressure at outlet. Using Selector Guide The pressure regulator on the unit is used to control the air pressure output. A low number, such as 10, indicates low pressure. A high number, such as 100, indicates high pressure. The selector guide is located on top of the unit for convenience. Locate the number across from the desired usage. For example: To inflate a basketball, the pressure setting is 5 - 15. Turn the regulator until gauge reads the desired pressure. Inflate the ball. The unit will automatically “bleed off” any excess pressure after the ball is inflated. Use care when referencing this guide. Overinflating is possible regardless of the suggested regulator setting. Some variance may be necessary. Always try the lowest suggested number first. If desired results are not achieved, use the next Extension cords for 120V/5 Amp Unit Length of Cord (ft) 25 50 100 higher number. Check the pressure with a separate pressure gauge. Wall Mounting This compressor is designed with an option to be hung on a wall or pegboard for convenient storage. It can also be operated while in the hanging position if one of the following conditions is met: 1. If mounted on a wall, mounting hardware is secured into wood or masonry with suitable fasteners. 2. If mounted on drywall or gypsum board, toggle bolts or mounting anchors are strong enough and are properly secure to resist vibration from the compressor. 3. If mounted on a pegboard, other items hung from the pegboard are secure enough to resist vibration from the compressor. On the bottom of the compressor are two keyhole-shaped mounting points that are spaced 4 inches apart. The compressor is designed to be hung with the hose outlet pointed downward. When installing on pegboard, hang from 1/4 or 1/8 inch hooks spaced 4 inches apart. When hanging from the wall, accurately space the fasteners exactly 4 inches apart horizontally or the compressor will not line up with the fasteners. The compressor is designed to hang from the head of the screw or nail.

The compressor should be checked often for any visible problems and the following maintenance procedures should be performed each time the compressor is used. 1. Turn power OFF and clean dust and dirt from motor, air lines and vent openings. IMPORTANT: Locate unit as far from spraying area as possible. LUBRICATION ! This is an oilless NOTICE type compressor requiring no lubrication. THERMAL OVERLOAD PROTECTORS This compressor is equipped with automatic reset thermal overload protectors which will shut off the motors if they become overheated. If thermal overload protectors shut motor OFF frequently, look for the following causes. 1. Low voltage. 2. Extended use. Thermal shutdown is normal when compressor is used for extended period of time. 3. Lack of proper ventilation. 4. High ambient temperature. If the thermal overload protectors are actuated, the motor must be allowed to cool down before start-up is possible. The motor will automatically restart without warning if left plugged into electrical outlet and unit is turned on. STORAGE 1. When not in use, store hose and compressor in a cool dry place. 2. Disconnect hose and hang open ends down, to allow any moisture to drain. Technical Service For information regarding the operation or repair of this product, please call 1-800-543-6400.
