Loctite 175, Руководство по эксплуатации, Страница: 6 / 14

5 Operation
Normal use:

Assemble the stand and place the tool in an upright position on a flat surface.

Plug the tool into the power supply socket, and switch on the power.

Wait 5 minutes for the tool to reach its normal operating temperature.

Squeeze the trigger to advance the handle/plunger and extrude molten adhesive
through the nozzle.

To stop extruding adhesive simply release the trigger.
During use, the plunger will advance through the breach area of the barrel as the
trigger is pulled. A point will be reached where the plunger no longer advances, but
just moves back and forth. When this occurs the tool needs reloading with another
adhesive cartridge.

Pull the handle back fully.

Insert a new adhesive cartridge.

Operate the tool normally.
5.1 The Auto Standby Feature
With a tool as powerful as the Loctite
®
175 Hot Melt Dispenser there would
be a risk of adhesive ‘meltdown’if it were left unused for too long at its
normal operating temperature. To avoid this, a special standby function is
built into the temperature controller, lowering the temperature of the tool
automatically after a period of inactivity. It should be noted, however, that
this function is not time-dependent, but temperature-dependent, i.e. the
standby will activate at a point dependent on the ambient temperature and on
the temperature of the tool itself. A yellow light will illuminate when the
standby feature is active and the tool begins to cool down. If left long enough
the tool’s temperature will drop to approximately 270°F (130°C) and stabilise.
When the trigger is pulled to use the tool again, the yellow light will
extinguish, and the tool will begin to heat up to it’s normal operating
temperature (IT MAY TAKE SEVERAL TRIGGER PULLS BEFORE THE
LIGHT REMAINS EXTINGUISHED AFTER THE TRIGGER IS
RELEASED). The adhesive may appear very viscous at this point, but will
quickly thin as the temperature returns to normal.
When the tool is used for normal high output applications it is unlikely that the
standby feature will operate.
5.2 Temperature adjustment
Temperature adjustment of the tool is achieved using a range of electronic
Plug-In Modules with pre-set values. Simply select the required value (check
that the Plug-In Module is the appropriate one for the adhesive to be used,
referring to the Spares and Accessory lists at the end of this manual) and insert
the module into the socket on top of the tool.
