AIR SUPPLY & ASSEMBLY
3.1.
Air supply
3.1.1. You will require an air pressure of 60-90psi, and an air flow of 5cfm to operate the unit efficiently.
3.1.2. WARNING! Ensure air supply is clean, dry and does not exceed 80psi. Too high an air pressure and/or unclean or damp air
will shorten the product life due to excessive wear and may be dangerous, causing possible damage and/or personal injury.
3.1.3. Drain the air supply tank daily. Clean compressor air inlet filter weekly. For recommended hook-up see diagram below.
3.1.4. Line pressure should be increased to compensate for
unusually long air hoses (over 8 metres). The minimum
hose and fittings bore should be 10mm.
3.1.5. Keep hoses away from heat, oil and sharp edges.
Check hoses for wear and poor connections.
3.1.6. Cabinet input connection is ¼"BSP.
3.2.
Assembly
Note: Numbers in brackets refer to item numbers shown in the
Parts List.
3.2.1. Unpack the product and check contents. Should there be any damaged or missing parts contact your supplier immediately.
3.2.2. Push clear plastic input hose (22) onto input pipe (21). Place suction tube in base of cabinet via triangular cut-out in mesh (7).
3.2.3. Secure the air inlet tube (9) to the front of the cabinet by pushing the end of the connector (18) through the aperture in the bottom right
corner and screwing an air coupling (not supplied) to it.
3.2.4. Remove plug. (Fig.1.)
4. OPERATING INSTRUCTIONS
WARNING! Ensure you read, understand and apply safety instructions in Section 1 before using the unit.
NOTE! We strongly recommend that a suitable dust extraction system is used with this unit.
If dust extraction is not used, media may be forced out of the joints as pressure builds up. You can alleviate this to some extent by
removing the white blanking plug (Fig.1) situated on the upper left corner at the rear of the tank when viewed from the front. This
however will not substitute a suitable dust extraction system.
4.1.
Connect the air supply to the inlet on the front of the cabinet. Ensure the gun valve is in the "off" position before connecting the air supply.
4.2.
Check all fittings to ensure that there are no air leaks.
4.3.
Pour the abrasive media into the centre of the cabinet. DO NOT use more than 4.5kg. Excessive amounts of abrasive will impair
visibility, create poor blasting performance and could block the air exhaust.
4.4.
Fit the required nozzle into the gun and retain with the set screws. The larger the abrasive particles, the larger the nozzle required.
4.5.
Plug the transformer into a mains socket and the transformer lead into the socket on the back of the cabinet.
4.6.
Place the workpiece in the cabinet and close and latch the door(s) securely.
WARNING! Failure to close the doors securely could result in damage and/or personal injury.
4.7.
Turn on light (switch to left of viewing window) and air supply and insert hands into cabinet gloves. Grasp gun and depress the trigger to
start the blasting process.
4.8.
Move the blast media (which looks like steam) continuously over the workpiece in an even and circular motion. To avoid undesirable
peening the flow should not be too hard or concentrated. The surface finish may vary from coarse to fine depending on the size of the
abrasive media. On delicate workpieces, to avoid unnecessary peening or excessive abrasion, begin the blasting with a low airflow.
