Installation   Before using the tool for the first time check it carefully for signs of external damage. If   any transit damage is found DO NOT USE THE TOOL - return it to your supplier   immediately.   Steps 1 – 5 should be followed before connection to the mains supply:   1.   2.   Insert the applicator stand into the grooves at the base of the handle. Stand   applicator on a flat surface.   Connect the air supply hose to a clean, dry and regulated air supply using the   Quick-Disconnect fitting provided (use of a filter/regulator is recommended)   Pull piston back fully and rotate upwards.   Load two adhesive cartridges into the barrel of the tool and push fully forward.   Rotate the piston down and slide forward fully until it contacts the rear of the   adhesive cartridge - it should engage about 5/16" (6-8mm) into the applicator   barrel.   3.   4.   5.   4 5 3 2 USERS AIR SUPPLY   1 6.   7.   Connect tool to mains supply.   Red ‘Power On’ indicator light illuminates.   Page 3   Download from Www.Somanuals.com.

Operation   Normal use:   • • Fit the stand and place the applicator in an upright position on a flat surface.   Plug the applicator into the power supply socket, and switch on the power. Wait 10   minutes for the applicator to reach its normal operating temperature.   Squeeze the trigger to advance the piston and extrude molten adhesive through the   nozzle.   • • To stop extruding adhesive simply release the trigger.   During use, the piston will advance into the barrel as the trigger is pulled. A point will   be reached where the piston no longer advances, and the sound of air escaping can   be heard - this indicates that the applicator needs reloading.   • • • • Release the trigger.   Pull the piston back.   Insert a new adhesive cartridge.   Operate the tool normally.   5.1. Applying Adhesive - Spray Adjustment   Turn the spray air adjustment control completely clockwise. Holding the applicator   facing away from you, squeezing the trigger will extrude a bead of adhesive from the   nozzle. While continuing to squeeze the trigger, rotate the spray air adjustment control   slowly counter-clockwise; this changes the adhesive bead into an ever-finer spiral   spray pattern. Continue to adjust the control until a suitable spray pattern is obtained   to suit your application. To stop the adhesive flow simply release the trigger.   5.2. Adhesive Flow Rate Adjustment   The flow rate of adhesive is dependent on the air pressure to the piston, and this is   adjusted by varying the setting of the pressure regulator on the air supply to the   applicator.   The air pressure operating range for the applicator is:   Minimum   Maximum   45 p.s.i. (3 bar)   100 p.s.i. (7 bar)   USERS AIR SUPPLY   . Page 4   Download from Www.Somanuals.com. All Manuals Search And Download.   6. Application Hints   As with all adhesives, performance depends on conditions of use. Suggestions or   recommendations contained herein are for guidance only, since actual conditions of   use are outside the supplier’s control.   • • Ensure that the surfaces to be bonded are dry, free from dust, grease, and   loose particles.   Apply adhesive to one surface only. Bring the two surfaces together as   quickly as possible; the faster the bond is made, the greater the strength.   A heavier spray pattern increases both working time and bond strength.   When gluing dissimilar materials, apply the adhesive to the least heat   conductive of the two.   • • • • On materials that are cold to the touch, a better bond can be made by pre-   warming them before applying adhesive.   Surplus adhesive can be trimmed using a sharp knife once it has cooled.   Should molten adhesive drip onto a smooth or polished surface, allow it to cool   completely before removal.   • • Spray adhesives can be applied directly to expanded polystyrene and other   plastic foams.   Use only genuine Loctite® Hysol® adhesives to ensure reliable performance.   Loctite® Hysol® adhesives are non-toxic and non-flammable.   7. Troubleshooting   Before proceeding with any repair or maintenance operation disconnect the tool   from the mains electricity supply.   Glue “Backup” and “Meltdown”   “Backup” occurs when hot molten adhesive in the glue chamber is forced back   between the barrel wall and the outside surface of the adhesive cartridge and piston.   Once this adhesive cools, it may lock the adhesive cartridge in the barrel, preventing,   or at least restricting, normal extrusion. By far the most likely cause of backup is   allowing insufficient warm-up time before operating the tool (the molten glue in the glue   chamber cannot escape forwards because the nozzle is blocked, due to being   insufficiently warm). In the vast majority of cases the backup self-clears once the tool,   having fully reached operating temperature, is operated again. For the rare occasions   where the backup does not self-clear, turn the spray air adjuster fully clockwise; this   will switch off the spray air, allowing the full pneumatic line pressure to be applied to   the piston (the tool will operate as a bead tool).   "Meltdown" occurs when the rear of the adhesive cartridge softens to the extent that it   is not rigid enough to drive the cartridge forward without collapsing. As with backup,   the molten adhesive can solidify, potentially locking the cartridge and / or piston into   the barrel. Meltdown is caused by leaving the tool switched on for extended periods of   time without operating it. It is recommended that, if the tool is to be left standing for   forty minutes or more, it should be switched off and only switched back on when   preparing to use it again.   The Loctite® Hysol® 175-SPRAY and 175-SPRAY-HT tools are fitted with specially   coated pistons which have non-stick characteristics far superior to any PTFE coating;   this minimises the effect of any backup or meltdown, should it occur.   Page 5   Download from Www.Somanuals.com.

Care and Maintenance   Every attempt has been made to make this exceptionally powerful tool both reliable   and trouble-free. However the following precautions should be noted:   • • Make sure that the applicator is up to temperature before attempting to operate.   Do not leave the applicator switched on for long periods without use. If the   applicator is not to be used for forty minutes or more, switch it off and restart when   required.   • Keep the applicator upright when not in use, never lay it on its side. Always use the   stand provided, or the optional bench stand or suspension unit (see Spares and   Accessory lists at the end of this manual).   • • Do not use excessive force on the trigger. Ensure that the tool has fully warmed up   before use.   Keep the nozzle clean to prevent adhesive build-up. This is easily done by wiping   the nozzle with clean paper or cloth while the nozzle is still warm.   9.
