READ THIS SECTION CAREFULLY BEFORE USING THIS EQUIPMENT/APPARATUS. 1.2.1 Heavy metal paint, asbestos and other toxic material dusts will cause serious lung disease or death without the use of properly designed and approved supplied air respiratory (SAR) equipment by blast operators and all personnel within the work site area. 1.2.2 The compressor must have adequate output and the plumbing between the compressor and the point of attaching the air supply hose must have sufficient capacity to supply the volume of air at the pressure required. 1.3 Standard safety precautions 1.3.1 Approved safety eyewear, hearing and footwear protection should be worn at all times by the operator and all personnel in the immediate area that may be exposed to hazards generated by the abrasive blasting process. 1.3.2 Suitably approved respiratory protection (PPE) should also be worn when handling abrasive media, abrasive refuse dust and when carrying out any service and maintenance work where dust may be present. 1.3.3 Any work performed on any electrical wiring or components must only be carried out by suitably qualified and registered electrical personnel. 1.3.4 Under no circumstances should any safety interlocks/lockouts or features be altered or disabled in any way. 1.3.5 All equipment must be isolated from the compressed air supply and electrical power supply prior to service or maintenance work being carried out. 1.3.6 All care must be taken by the operator(s) when lifting or moving equipment or components in order to prevent injury. Blast pots must always be emptied of abrasive media before any attempt is made to move them. 1.3.7 Any modification to the equipment or its components or use of non-genuine PanBlast replacement parts will void warranty. 1.3.8 Always check the Material Safety Data Sheet (MSDS) relating to the abrasive media being used. Ensure that the abrasive media is free of harmful substances, in particular, free silica, cyanide, arsenic or lead. 1.3.9 Test the surface which is to be blasted for harmful substances, taking the appropriate measures to ensure the safety of all personnel. 1.3.10 The operator should carry out a daily inspection of all related components prior to startup of all wearing and safety items to ensure they are in correct operating order. In particular check all hose couplings and nozzle holders, ensuring that all hose couplings are fitted correctly, the safety locking pins are engaged and in good order. Always install safety whip check cables at every hose connection. Ensure that the blast nozzle has been securely screwed into the nozzle holder and the nozzle holder has been secured to the blast hose correctly and all screws are engaged. NOTE: UNDER OSHA 1915:34(c)(1)(iv) DEAD MAN CONTROL. A DEADMAN CONTROL DEVICE SHALL BE PROVIDED AT THE NOZZLE END OF THE BLAST HOSE EITHER TO PROVIDE DIRECT CUTOFF OR TO SIGNAL THE POT TENDER BY MEANS OF A VISUAL AND AUDIBLE SIGNAL TO CUT OFF THE FLOW, IN THE EVENT THE BLASTER LOSES CONTROL OF THE HOSE. THE POT TENDER SHALL BE AVAILABLE AT ALL TIMES TO RESPOND IMMEDIATELY TO THE SIGNAL. 2.0 INTRODUCTION 2.1 Scope: These instructions cover the installation, operation and maintenance of the PanBlast AirStop II Pneumatic Control Handle. 2.2 Application: The PanBlast AirStop II Pneumatic Control Handle is a spool type plunger valve deadman handle used for the remote control operation of abrasive blasting pots. When operated it supplies a pneumatic signal to the blast pot remote control system which then activates the abrasive blasting process. 2.3 The PanBlast AirStop II Pneumatic Control Handle is utilized in conjunction with the Panblast range of remote control valve systems, which include the UniFlo, Helix, Sola, Kombi, Tandem and Safe-T-Pinch Valve systems. 3.0 INSTALLATION 3.1 Attach the AirStop II Pneumatic Control Handle to the blast hose behind the nozzle holder using robust bands or strapping, trim any excess strapping after fixing the control handle to prevent catching or interference with the blasting operator during the abrasive blasting process. 3.2 Connect the twinline hose fittings to the remote control handle ensuring that the air supply line - 1 -
is connected to the inlet port and the return air signal line is connected to the outlet port. 3.3 It is recommended that the twinline hose is strapped to the blast hose at one (1) meter intervals. 3.4 Connect the two end fittings to the blast pot remote control valve system at the blast pot via the quick connect fittings supplied on the twinline hose assembly and the matching fittings on the blast pot remote control valve. 4.0 OPERATING INSTRUCTIONS 4.1 The PanBlast AirStop II NPT Pneumatic Control Handle is a spool type plunger valve deadman handle. When the lever handle is in the up or un-activated position, the air supply from the blast pot supply is closed off at the remote control handle. When the lever handle is depressed or in the activated position, the plunger directs air from the inlet port to the outlet port supplying a return air signal to the blast pot remote control valve system activating the blast pot and initializing the abrasive blasting process. 5.0 MAINTENANCE 5.1 Check the operation of the lever safety lock and lever handle on a regular basis. 5.2 Replace any broken or faulty components immediately. 5.3 Check the condition of the bumper button on the underside of the lever handle, replace if worn. 5.4 Ensure that the plunger sleeve and O-rings are in good condition and that the plunger plug is located correctly on the plunger. 5.5 Ensure that the remote control handle strapping is in good order, replace as required. 6.0 TROUBLE SHOOTING GUIDE PROBLEM PROBABLE SOLUTION Ensure that the safety mini ball valve or safety pet cock on the remote control valve has been closed. 4.2 Before pressurizing the system check the operation of the remote control handle, is the lever safety lock operational? Does the lever safety lock return back to the up position on releasing of the lever handle? Does the lever handle immediately return back when released? Ensure that the lever handle is free in its action. 4.3 Connect the blast pot to an air supply that is adequate for the application, check the blast nozzle air volume requirement and the minimum air pressure required to operate the remote control valve. 4.4 Ensure that the safety mini ball valve or safety pet cock on the remote control valve is in the isolated / closed position.! WARNING! NEVER EXCEED THE MAXIMUM OPERATING PRESSURE OF 150PSI (10.4BAR), AS THIS MAY RESULT IN SERIOUS INJURY OR DEATH. 4.5 After following all of the start-up procedures as detailed in the blast pot operating manual, push the lever safety lock down, hold the lever safety lock down and depress the lever handle. This will send a signal to the remote control valve and initiate the abrasive blasting process. Blasting will begin within a few seconds. 4.6 To stop blasting, release the lever handle, the lever safety lock will engage preventing the lever handle from being depressed and the pneumatic signal is isolated, abrasive blasting will cease within 2-3 seconds.! WARNING! THE LEVER HANDLE MUST NEVER BE WIRED OR STRAPPED DOWN, TO DO SO MAKES THE AIRSTOP II CONTROL HANDLE INOPERATIVE AS A SAFETY DEVICE AND MAY RESULT IN SERIOUS INJURY OR DEATH TO THE OPERATOR OR PERSONNEL IN THE NEAR VICINITY. The lever handle is depressed but the remote control valve does not operate. The lever handle does not return up when released. The lever safety lock does not return back to the safety position. The abrasive blasting commences as soon as compressed air is engaged without the lever handle being depressed. Check that the lever handle is free in its action and not being obstructed on the lever safety lock. Ensure that the inside of the lever handle is free of burrs and edges and that the lever safety lock is also free of burrs on the outer edge. Replace if required. Check that the lever handle hinge pin is not obstructed due to intrusion of abrasive dust. Check that the lever handle spring has not been damaged and is free in its action. Replace if required. Check that the lever handle pin is not obstructed due to intrusion of abrasive dust. Check that the lever safety lock spring has not been damaged and is free in its action. Check that the lever safety lock is not obstructed due to abrasive dust. Check that the twinline hose is connected correctly, i.e. the air supply line is connected to the inlet port and the air signal line to the outlet port. Check that the plunger is free in its movement. Refer to the blast pot remote control system operating manual. - 2 -
