Hilti HIT-HY 150 MAX 1400 Jumbo Mode D'emploi page 9

• Flush again 2 times until water runs clear. Remove all standing water completely (i.e. vacuum,
compressed air or other appropriate procedure). To attain a dried borehole, a Hilti HIT-DL air noz-
zle attachment is recommended for borehole depth ≤ 250 mm and required for borehole depth >
250 mm.
• Continue with borehole cleaning as described in Method 1.
 Insert foil pack in foil pack holder. Attention! Check foil packs and foil pack holder for proper func-
tioning or damage - especially after they have been dropped. Dropping foil packs, also foil packs
already inserted into the foil pack holder, is likely to cause damage leading to mal function. Never use
damaged foil packs and/or damaged or unclean foil pack holders.
 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 anchor adhesive.
 Insert foil pack holder with foil pack into HIT-dispenser P 8000 D.
 Discard initial anchor adhesive. Do this by pulling the empty outer packaging over the mixer and
holding it there to prevent mortar squirting out. Dispense a quantity of approx. 45 ml (quantity cor-
responds to a cylindrical shape of approx. 50 mm diameter and height of 25 mm) into the bag and
dispose of this. The foilpack opens automatically as dispensing is initiated. Do not pierce the foilpack
manually (can cause system failure). 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 anchor adhesive from the back of the borehole without forming air voids:
• Injection method – for borehole with depth ≤ 250 mm:
Inject the anchor adhesive starting at the back of the hole (use the extension for deep holes), press
the dispenser trigger in variable speed regulation mode and slowly withdraw the mixer as mortar is
dispensed. Fill holes approximately 2/3 full, or as required to ensure that the annular gap between
the anchor/rebar and the concrete is completely filled with anchor adhesive along the embedment
length.
• Piston plug injection is recommended for overhead applications and borehole depth > 250 mm.
Assemble HIT-RE-M mixer, extension(s) and appropriately sized piston plug. Insert piston plug
HIT-SZ to back of the hole, and inject anchor adhesive as described in the injection method above.
During injection the piston plug will be naturally extruded out of the bore hole by the anchor adhe-
sive pressure.
 Insert anchor/rebar into bore hole. Mark and set anchor/rebar to the required embedment depth.
Before use, verify that the anchor/rebar is dry and free of oil and other contaminants. To ease installa-
tion, anchor/rebar may be slowly twisted as they are inserted. Use only Hilti anchor rods or equivalent.
After installing an anchor/rebar, the annular gap must be completely filled with anchor adhesive.
 Observe the gel time "t gel", which varies according to temperature of base material. Minor adjustments
to the anchor/rebar position may be performed during the gel time. See table 11. Once the gel time has
elapsed, do not disturb the anchor/rebar until the curing time "t cure" has elapsed.
