Adhesive mortar for anchor and rebar fastenings
Suitable for use in hollow and solid clay brick, sand-lime block, concrete, concrete block, cellular concrete and natural stone

Restricted to professional users. Read the instructions for use and safety instructions before using this product.

• Expiry date: see imprint on manifold (month/year). Do not use expired mortar!
• Transport and storage : cool, dry and dark, +5 °C to 25 °C.
• Foil pack temperature: must be between +5 °C and 40 °C during application.
• Base material temperature: must be between 0 °C and 40 °C during application
• Exception in solid clay brick: between +5 °C and 40 °C. The foil pack opens automatically at start of dispensing.
• Installation instructions : Illustration of the sequence of operations: see pictograms 1-17
• Detailed setting data: for hollow materials see table 1; for solid materials see tables 2 and 3.

1. Drill the hole with a rotary hammer. Check to determine whether the material is solid or hollow (with cavities). Use of a diamond coring tool to drill the hole is not permissible.

2. Clean the drilled hole immediately before setting the anchor: 2 x blowing – 2 x cleaning with a wire brush – 2 x
   blowing. Holes must be free of dust, water, ice, oil/grease and other contaminates. Inadequate hole cleaning = poor load-bearing values

3. Base materials with cavities ➔ Use a mesh sleeve – either HIT-SC composite mesh sleeve or HIT-S metal mesh sleeve. Do not use damaged sleeves.

• HIT-SC : First fit the centering cap, check that it engages (5) and then insert the mesh sleeve in the drilled hole (7).
• HIT-SC sleeve combinations: Fit the centering cap on the outer mesh sleeve (5), connect the outer mesh sleeve to the inner mesh sleeve (6), check that parts are well engaged and then insert the combined sleeves in the hole (7).
• Place the foil pack in the foil pack holder. Caution! Never use damaged foil packs and/or damaged or very dirty foil pack holders. Screw the mixing nozzle tightly onto the foil pack. Do not modify the mixing nozzle in any way, unless specified by Hilti. A new mixing nozzle must be used with each new foil pack. Insert the foil pack holder, with the foil pack, in the dispenser.
• Discard initial quantity of mortar : Do not use the initial quantity of mortar dispensed from the mixing nozzle for making fastenings. The quantity of mortar to be discarded depends on the size of the foil pack. See pictogram 11. The initial quantity of mortar must be discarded each time the mixing nozzle is changed.
• Filling the HIT-SC plastic mesh sleeve : Fill the mesh sleeve with mortar from the centering cap until mortar escapes at the centering cap (filling control) (13).
• Filling HIT-SC mesh sleeve combinations: Push the mixing nozzle through the centering cap and through the bottom of the outer mesh sleeve (if necessary: use mixer extension). Fill the inner mesh sleeve (12).
• For the number of trigger pulls required: see table 1. Then pull the mixing nozzle back to the centering cap of the outer mesh sleeve and fill the outer mesh sleeve until mortar escapes from the centering cap (filling control) (13).
• Filling the HIT-S metal mesh sleeve: Insert the mixing nozzle to the bottom of the mesh sleeve and then retract the mixing nozzle approx. 10 mm after each trigger pull of the dispenser.
• Solid materials: Fill the drilled hole without trapping air! Insert the mixing nozzle to the base of the borehole (use an extension for deep holes) and then retract the nozzle, step by step, after each trigger pull of the dispenser. Fill the hole to approx. 2/3 with mortar.
• Push the fastening element into the mortar-filled hole or mesh sleeve up to anchoring depth „hef“ in accord-ance with tables 1-3. Afterwards the annular gap must be completely filled with mortar. Observe the working time „tgel“, which varies according to temperature of base material.

Once the working time „tgel“, has elapsed, do not move or apply a load to the fastening element until the curing time „tcure“ has passed. A load may be applied to the fastening element only after the curing time „tcure“ has elapsed.

Partly-used foil packs may be reused within 4 weeks. Leave the used mixing nozzle screwed on and store the partly-used foil pack in accordance with storage instructions. Before reuse, screw on a new mixing nozzle and discard the initial quantity of mortar dispensed, as described at paragraph 11.

Hilti accepts no liability for loss or damage caused by:

• storage or transport not in accordance with the specified conditions.
• failure to observe the instructions for use and the setting data.
• inadequate design of the anchor points (number of anchors, load-bearing capacity/dimensions).
• inadequate load-bearing capacity of the base material or use of the product on base materials other than those recommended.
• incorrect use.
• other influences of which Hilti is not aware or on which Hilti has no influence, e.g. use with products from third parties (e.g. climbing anchors).
  Note : Hilti HIT-MM PLUS is not tested for use with climbing anchors. Applications of this kind are carried out at the user‘s own risk.
