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
immediately, quickly making any further adjustments. Hold the joint for 20 -
30 seconds to complete the bond.

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 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.

Spots or blobs of adhesive are recommended for work pieces having a large
surface area, or which are particularly long.

Applying the adhesive in wavy lines is recommended for gluing textiles or
similar materials.

Foam materials, like polystyrene, can be easily bonded to other surfaces.
However the adhesive must be applied to the other surfaces, not to the foam.

Use only genuine Loctite
®
Hot Melt adhesives to ensure reliable performance.
Loctite

Hot Melt adhesives are non-toxic and non-flammable.
7 Troubleshooting
Before proceeding with any repair or maintenance operation disconnect the tool
from the main electricity supply.
If the adhesive cartridge does not advance when the trigger is pulled, check that the
tool is plugged into the main supply, switched on, and has had sufficient time to warm
up. Otherwise carry out the ‘Snubber Adjustment’as follows:
7.1 Snubber Adjustment
THIS IS FACTORY-SET BUT MAY REQUIRE MINOR ADJUSTMENT
AFTER AN INITIAL BEDDING-IN PERIOD
The snubber is a spring-loaded friction pad, which rubs on the side of the feed
bar, preventing its backward movement when the trigger is released. With the
snubber correctly adjusted, the plunger should remain stationary when the
trigger is released. If there is a backward movement, more snubber pressure is
required. To increase pressure turn the adjustment screw clockwise using a
3mm hexagon key. Turn a quarter-turn each time and test. SEE DIAGRAM
ON NEXT PAGE.
Do not over tighten, as this will make plunger retraction difficult and cause
premature wear on the snubber pad.
