worn. Careless handling can cause skin burns. If molten adhesive comes into
contact with the skin immerse the affected area immediately in plenty of cold water.
Seek medical advice if necessary.
In addition to the safety instructions herein, any statutory regulations, local fire
insurance regulations, or other generally valid “regulations for accident prevention”
must be complied with when using this tool.
• Never use the tool if it is damaged in any way.
• Do not use this tool in damp rooms, outdoors while it is raining, or where there is
high humidity.
• Do not use this tool in the vicinity of any heat-sensitive materials, or any flammable
materials, liquids, or gases.

2. Description
The Loctite
held industrial spray hotmelt applicators available. With its two powerful 250W
stainless steel cartridge heaters, they are capable of dispensing up to 9 lbs. of molten
hotmelt per hour, yet only take 10 minutes to warm up from cold.
Supported by a range of spray adhesive formulations, the Loctite
and 175-SPRAY-HT are suitable for most applications - they can even be used with
heat sensitive substrates such as expanded polystyrene and other plastic foams.
Also, the Loctite
non-toxic, so there are none of the environmental problems often associated with other
spray adhesive applicators.
Designed to comply with world wide safety standards, the Loctite
and 175-SPRAY-HT also feature a totally enclosed heater housing, and are fitted with
thermal fuse protection.

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.

Maximum - 100 p.s.i. (7 bar)
Steps 1 – 5 should be followed before connection to the mains supply:
1. Insert the applicator stand into the grooves at the base of the handle. Stand
applicator on a flat surface.
2. 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)
3. Pull piston back fully and rotate upwards.
4. Load two adhesive cartridges into the barrel of the tool and push fully forward.
5. 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.

8. Allow the applicator to thoroughly warm up for 10 minutes. Do not attempt to
operate the applicator until this time has elapsed.
5. 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 45 p.s.i. (3 bar)
Maximum 100 p.s.i. (7 bar)
.

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

7. Troubleshooting
®
®
Hysol ® adhesives are non-toxic and non-flammable.
Hysol®adhesives to ensure reliable performance.
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.

8. 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.
