Hilti HIT-RE 500-SD Manual De Instrucciones página 9

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 in-
sert foil pack holder into the appropriate Hilti dispenser.
Discard initial adhesive. Dispose discarded mortar into the empty outer packaging. Do not use the in-
itial 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 ad-
hesive has to be discarded. Caution! Never remove the mixer while the foil pack system is under pres-
sure. 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, re-
peat cleaning according points 2 - 4.
•Inject the adhesive starting at the back of the borehole (use the extension for deep boreholes), slow-
ly 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 injec-
tion 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 re-
quired embedment 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 adhe-
sive.
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 in-
staller. 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 du-
ring this time.
Apply load/torque after "t cure,full" has passed, and the fixture to be attached has been positioned.
