Tightly attach Hilti HIT-RE-M mixer to foil pack manifold. Attach new mixer prior to dispensing a new foil pack

(snug fit). Do not modify the mixer in any way. Make sure the mixing element is in the mixer. Use only the

type of mixer supplied with the adhesive.

Insert foil pack holder with foil pack into HIT-dispenser. Push release trigger, retract plunger and insert foil

pack holder into the appropriate Hilti dispenser.

Discard initial adhesive. Dispose discarded mortar into the empty outer packaging. Do not use the initial

amount of mortar for fastenings. See pictogram 8 for discard quantities. The foil pack opens automatically

as dispensing is initiated. Depending on the size of the foil pack an initial amount of adhesive has to be

discarded. Caution! Never remove the mixer while the foil pack system is under pressure. Press the release

button of the dispenser to avoid mortar splashing. If a new mixer is installed onto a previously-opened foil

pack, the first trigger pulls must also be discarded as described above. For each new foil pack a new mixer

must be used.

Inject adhesive from the back of the borehole without forming air voids:

Verify if borehole conditions have changed (e.g. water in the borehole) after cleaning. If yes, repeat cleaning

according points 2 - 4.

• Inject the adhesive starting at the back of the borehole (use the extension for deep boreholes), slowly

withdraw the mixer with each trigger pull. Fill holes approximately 2/3 full. After injection is completed,

depressurize the dispenser by pressing the release trigger. This will prevent further adhesive discharge

from the mixer.

• Piston plug injection - is recommended for borehole depth > 250 mm. For overhead installation the

injection is only possible with aid of piston plugs Hilti HIT-SZ.

Assemble HIT-RE-M mixer, extension(s) and appropriately sized piston plug HIT-SZ. Insert piston plug to

back of the borehole and inject adhesive as described in the injection method above. During injection the

piston plug will be naturally extruded out of the borehole by the adhesive pressure.

Insert fastening element (rebar / anchor) into borehole. Mark and set fastening element to the required em-

bedment depth. Before use, verify that the fastening element is dry and free of oil and other contaminants.

After installing a fastening element, the annular gap must be completely filled with adhesive.

Attention! For overhead applications take special care when inserting the fastening element. Excess ad-

hesive will be forced out of the borehole - take appropriate steps to prevent it from falling onto the installer.

Position the fastening element and secure it from moving/falling during the curing time (e.g. wedges).

Observe the gel time "t gel", which varies according to temperature of base material. Minor adjustments to

the fastening element position may be performed during the gel time. See table.

Do not disturb the fastening element once the gel time "t gel" has elapsed until "t cure,ini" has passed.

Preparation work may continue for rebar applications. Between "t cure,ini" and "t cure,full" the adhesive

has a limited load bearing capacity, do not apply a torque or load on the fastening element during this time.

Apply load/torque after "t cure,full" has passed, and the fixture to be attached has been positioned.
