damaged.

Notice:

Provides recommendations for better handling of the unit during operation or
adjustment as well as for service activities.

1.2 Safety

Do not touch the nozzle or molten adhesive with bare skin as they are hot - the
operating temperature of the Loctite®175 Hot Melt Dispenser is
approximately 400ºF (200ºC). Protective gloves should always be 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

2 Description

The Loctite®175 Hot Melt Dispenser contains a powerful 400W stainless steel
cartridge heater which, in conjunction with it’s adjustable solid-state electronic
controller, provides both a fast 5-minute warm-up, and accuracy in temperature
control to within +/- 10°F (5°C) of the set temperature. Temperature adjustment is
achieved by changing the plug-in module –the operator simply chooses the most
appropriate module for the adhesive formulation to be used.

The advanced electronic controller provides an Auto Standby feature, allowing the
tool to be left on for long periods of time without the adhesive overheating (however
care should still be taken with soft formulations). If left unused for a while the tool
will, after a variable time (depending on the ambient temperature), switch to its
power-saving standby-mode, reducing the temperature of the tool to approximately
270°F (130°C); it will return to it’s full operating temperature when operated.

Designed to comply with world wide safety standards, the Loctite®175 Hot Melt
Dispenser also features a totally enclosed heater housing, and is fitted with thermal
fuse protection.

4 Installation

Before using the tool for the first time check it carefully for signs of external damage.
If any shipping damage is found DO NOT USE THE TOOL - return it to your
supplier immediately.

Steps 1 –5 should be followed before connection to the main power supply:

1. Assemble the enclosed stand into the grooves at the base of the handle.

2. Check that the Plug-In Module is the appropriate one for the adhesive to be
used (refer to the Spares and Accessory lists at the end of this manual).

3. Pull handle back fully.

4. Drop adhesive cartridge into the breach of the tool and push fully forward.

5. Advance handle/plunger to rear of the adhesive cartridge by operating trigger.

ADHESIVE CARTRIDGES

6. Connect tool to main power supply.

7. Red “Power On”indicator light will illuminate.

8. Allow tool to warm up for 5 minutes. Do not attempt to operate the tool until
this time has elapsed.

9. Operate trigger to push the adhesive cartridge forward to the reloading point.

10. Pull handle back fully and load a second adhesive cartridge. Operate trigger to
advance handle/plunger.

With a new tool it will be necessary to operate the trigger several times before

adhesive can be extruded; air trapped in the heater housing needs to be evacuated.
