Save This Manual NOTICE is used to address practices not related to personal injury. Keep this manual for the safety warnings and precautions, assembly, operating, inspection, maintenance and cleaning procedures. Write the product’s serial number in the back of the manual near the assembly diagram (or month and year of purchase if product has no number). Keep this manual and the receipt in a safe and dry place for future reference.
or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury. 2. 3. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts. Avoid accidental starting.
to follow maintenance instructions may create a risk of electric shock or injury. Air source a. b. Never connect to an air source that is capable of exceeding 200 psi. Over pressurizing the tool may cause bursting, abnormal operation, breakage of the tool or serious injury to persons. Use only clean, dry, regulated compressed air at the rated pressure or within the rated pressure range as marked on the tool.
9. Stay alert. Watch what you are doing. Use common sense. Do not operate any tool or equipment when you are tired. 10. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment and binding of moving parts, any broken parts, and any other condition that may affect proper operation.
23. NEVER use sand as a blasting medium. Abrasive blasting with media containing crystalline silica can cause serious or fatal respiratory disease. Exposure to crystalline silica may cause silicosis (a serious lung disease), cancer, and death. Exposure to aluminum oxide (a dust generated from material removing processes) can result in eye, skin, and breathing irritation. Always use an ANSI-approved respirator, safety impact eye glasses, and a full face shield. Avoid skin exposure.

SPECIFICATIONS Electrical Requirements Fluorescent Bulb Working Pressure Pressure Gauge Air Consumption Air Inlet Size Abrasive Capacity Inner Cabinet Front Window Accessories Weight Air Supply To prevent explosion: Use only clean, dry, regulated, compressed air to power this cabinet. Do not use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this cabinet. 120 V~ / 60 Hz / 40 W (Light) 110 V~ / 60 Hz / 12 A (Motor) 18 W, 23” L x 1” Dia.

operation: Do not install a female quick coupler on the cabinet. Such a coupler contains an air valve that will allow the cabinet to retain pressure and operate accidentally after the air supply is disconnected. Note: Air flow, and therefore cabinet performance, can be hindered by undersized air supply components. 3. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working. 4.
ASSEMBLY INSTRUCTIONS CAUTION! The Blast Cabinet weighs approximately 250 pounds, and will require additional assistance and/or a proper lifting device during the assembly procedures.

(22). Close and securely lock the Door Latch Assembly (35). (See Figures G and L.) OPERATION INSTRUCTIONS Abrasive Selection 1. 2. Abrasive blasting media include silicon carbide, glass bead, walnut shell, brass bead, and alumina. 3. If you decide to reuse media, remember, it does wear out. The sharp edges become rounder and are less effective. At that point you should replace the tank of media you are using.
type of media prematurely (i.e., glass bead). 3. Start by setting the Air Regulator (9) at 80 PSI. Most parts for blasting can be successfully blasted at 80 PSI. For light gauge steel, aluminum, and other more delicate parts start at a lower pressure and gradually increase the pressure until the desired finish is achieved. For more pressure, turn the Air Regulator Knob clockwise. For less pressure, turn the Air Regulator Knob counterclockwise. (See Figure J.
2. Disconnect the compressor air hose from the Quick Connector on the Air Regulator (9). (See Figure J.) 3. If necessary, empty the Cabinet (22) of any remaining media by unscrewing and removing the Metering Valve Plug (12). Always use Pipe Thread Seal Tape (41) when replacing the Metering Valve Plug. (See Figure I.) can bring blasting to an instant halt. Store media in a dry area and load the appropriate quantity (up to 15 pounds).
manual must only be performed by a qualified service technician. INSPECTION, MAINTENANCE, AND CLEANING WARNING! Prior to performing any inspection, maintenance, or cleaning of the Blast Cabinet, turn the Power Switch (1A) to its “OFF” position and unplug the unit from its electrical outlet. Turn off the air compressor. Press the Foot Pedal (11) of the Blast Cabinet to release any remaining compressed air in the system. Then, disconnect the compressor’s air hose from the Blast Cabinet. 1. 2.
away from the Blast Cabinet a pressure drop will result. The air supply line should be 1/2” diameter or larger. 5. Poor visibility (excessive dust). Make sure the Quick Coupler on the Air Regulator (9) is allowing air to the Cabinet (22). 6. Poor visibility (viewing window). The Glass Window (17) is equipped with a clear plastic protector on it and may become pitted. If necessary, replace the plastic protector and/or Glass Window. 7. Poor media flow.
