1. IMPORTANT WARNING Read all instructions before using this equipment. For efficient and safe production, reference OSHA requirements. Remember: 1.1 Safety considerations: - Blast machine requires high pressure air to operate. This needs to be piped to the cabinet with appropriately sized and rated pipe. - Supply air should be dry and clean from oil and other contaminants. (ie use air dryer, coalescent filter, or moisture separator as needed.) - Blast machine must be grounded to avoid shock. - Electric extension cords should be three wire grounded, and rated for the amperage of the blaster. Check nameplate for rated amps. - Dust from blast cabinet should be collected in a dust collector or dry filter and not allowed to become concentrated in areas where workers are exposed. This requires proper maintenance of dust collection system. 1.2 Operator's responsibilities before starting: - Inspect fittings and hoses for damage and wear. - Check the seal on all doors. Only operate the blast cabinet with all doors securely closed and dust collection system running. - Clean dust from dust collector and clean filter as needed. 1.3 Caution: - Watch for silicosis (from dust created when using silica sand as a blast media) or toxic dust hazard. DO NOT USE MEDIA CONTAINING FREE SILICA. - Unless otherwise specified, working pressure of blast machine and related components must not exceed 125 psi - Keep blast nozzle controlled and aimed at the work. 1.4 Maintenance - Disconnect power and air supply from machine before servicing. - Keep your machine in good repair. Use Mod-U-Blast parts and do not substitute or modify Mod-U-Blast supplied items. 2

3. SET UP 3.1 Location: Before setting up your cabinet remember the following points: Your Mod-U-Blast cabinet requires a compressed air supply and hose or pipe will need to be supplied from the existing supply (air compressor) to the cabinet. Your cabinet needs a power supply (usually 115 Volt, 60 Hz.) All parts of your cabinet are designed to be used in a heated indoor location. Dust can escape from the cabinet while loading and unloading the cabinet or while servicing the dust collector. Noise from the motor and blasting operation is not excessive but could disturb other processes or travel through light flooring. 3.2 Air: Supply air line should be sized according to the table shown on page 6. All hoses should be rated at least 125 psi. An isolation valve should be installed at the end of the rigid pipe followed by a connecting coupler or union. This allows the supply air to be turned off and then disconnected from blast machine for servicing. Your compressed air supply needs to be dry. Moisture in the air will cause problems. Other contaminants such as oil, will also cause decrease in production. Contact your Mod-U-Blast dealer if you are unsure of what is needed. WARNING: DO NOT CONNECT TO HIGH PRESSURE BOTTLED GAS, RUPTURE AND EXPLOSION CAN OCCUR. 3.3 Power Cords. Ensure any electrical cords used are rated for the voltage and amperage indicated on the name plate. 4
4. GENERAL OPERATING INSTRUCTIONS 4.1 Preparing parts for blasting - All parts processed must be free of oil, grease and moisture. Make sure parts are dry before putting into the cabinet for cleaning. 4.2 Air pressure - Set blasting pressure by adjusting knob on air regulator until gauge indicates desired pressure. (pull to unlock) - Operating pressure is usually from 50 to 80 psi. (pounds per square inch) - Higher pressures (up to 125) can be used but this breaks down some types of media prematurely.(ex. glass bead) -Set air pressure at 50-80 psi. Most parts for blast cleaning can be blasted at 80 psi. For light gauge steel, Aluminum, and other more delicate parts, start at lower pressure and gradually increase the pressure until the desired finish is achieved. 4.3 Filling with Media - For suction units with reclaimers, add enough to fill the bottom hopper on the reclaimer 2/3 full. - For pressure units, check the volume of the pot and add 3/4 of that volume initially. For these units media should not be piled above the top of the pot, into the reclaimer. This causes premature wear of the pop-up 4.4 Nozzle angle and distance - Direct nozzle at parts at 45-60 degree angle with ricochet towards the back of the cabinet. Do not hold nozzle at 90 degree angle to parts being processed. This will cause the media blast to bounce back into the blast stream and slow blasting action. Also 90 degree angle will cause excessive wear on nozzle and viewing window. Hold nozzle approximately 6 inches from parts being blasted. - Cabinets are available with safety doors so that the nozzle cannot be operated unless the doors are closed. Contact your MOD-U-BLAST dealer for further information. 4.5 Media - Media should be of good quality and dry. Moisture will cause poor media flow and will clog micro valve and hopper. NEVER USE SAND There are many types and sizes of media for different finishes. If you are having a problem selecting a media for a specific job, contact your distributor for recommendations. 4.6 Blasting -Turn on the electric switch, this will turn on the lights and the dust collector or the reclaimer. Using the gloves hold the gun and step on the foot pedal to start blasting. WARNING: NOZZLE MUST ALWAYS BE POINTED AWAY FROM THE OPERATOR AND TOWARDS ITEMS BEING PROCESSED. NEVER BLAST WITH ANY OF THE CABINET DOORS OPEN. 5

6. PRESSURE CABINETS P series The difference between a pressure cabinet and a suction cabinet is in how the media is mixed with the pressurized air stream. The suction cabinets have an air jet which sucks the media up to the gun and the media is mixed in just before it exits through the nozzle. Pressure cabinets mix the media in a grit valve that is pressurized and then the pressurized mixture travels through the hose to the nozzle. This greatly increases the speed at which the media leaves the nozzle thus increasing production substantially. EQUIPMENT: The media that is available for blasting is stored in the pressure pot which is attached to the bottom of the reclaimer. This unit is sealed and pressurized when the foot pedal is activated. This is done with the air inlet, pop-up and dump valves. 6.1 Air inlet valve (see pg 16&17, aqua valve, normally closed). The foot pedal will open this valve and let air into the pot and also feed air through the grit valve. This air is at the pressure set by the pressure regulator. 6.2 Pop-up valve (pg 11 part No.16). The air rushing into the pot will lift and close the pop-up valve. This seals the top of the pot and stops any further media from entering the pot to be blasted. This limits your continuous blasting time until the media inside the pot is used. Releasing the foot pedal will open the pop-up valve and allow the accumulated media in the reclaimer to drop into the pot. This will only take a few seconds and then the pot can be repressurized and blasting can continue. 6.3 Dump valve (pg 15 part No. 13). When the foot pedal is released the dump valve opens and releases the pressure in the pot. This reduces the time it takes for the nozzle to stop and the time before the media can fall into the pot past the pop up valve. This valve also makes the equipment safer because until the foot pedal is activated the pot is not under pressure. When the pot depressurizes it takes a few seconds for it to repressurize, it is therefore recommended that the operator not release the foot pedal for just a second or two as he will lose time as the pot is repressurizing. This short period is not long enough for the pot to refill either. 6.4 Grit valve: The amount of media being blasted can be adjusted at the grit valve (pg 15 part No. 37and pg 18 & 19) When the knob is backed out it is fully opened, all the way in is closed. The sleeve and gaskets will wear and should be checked and changed as required. AIR PRESSURE: As with the suction cabinets the blasting pressure is adjusted at the pressure regulator at the front of the cabinet. Blasting can typically be accomplished at lower pressures with a pressure cabinet as compared to a suction cabinet. Glass bead at 80 psi in a suction cabinet is equivalent to 50 or 60 psi in a pressure cabinet. 7

7. PRESSURE CABINET MAINTENANCE 7.1 Media Flow: If no media OR air are coming out of the nozzle there is probably a large particle stuck in the nozzle. Remove the nozzle from the nozzle holder, clean and replace. If there is air but no media, there may be something stuck in the bottom of the pot or grit valve. By closing the choke valve and blasting for a second and then reopening it the 3/4" ball valve on the side of the pot, air is allowed only into the pot. This often dislodges the media, after the media is flowing again return the valve to fully opened (handle down). Always use dry media, as caking is likely to occur if the media is wet or if the compressor is supplying humid air. 7.2 Pressure Drop: If the pressure shown at the regulator, drops significantly when blasting, there may be a hole worn through the hose. If the hole is in the section beneath the flooring this will not be immediately obvious. Replace hose. 7.3 Worn Nozzle: When the nozzle becomes worn, the air requirement increases. If your air supply cannot keep up, the blasting pressure will drop off. 7.4 Dust Collection: Pressure cabinets have a higher production rate and thus break down media quicker and remove coatings quicker. This increases dust. Therefore dry filters and dust bags need to be cleaned more often in order to maintain visibility. 7.5 Dump Valve: The dump valve seals the pot by pressing a rubber diaphragm against the manifold. If these pieces are badly worn, the pot cannot maintain pressure and media will stop flowing. 9
