WARNING
Poor load values / potential failure of fastening due to oversetting. Stop rotation of anchor rod immediately when reached the embedment depth.
– Check that the hole is drilled to the correct depth before setting the anchor. Hole depth is correct when the anchor rod contacts the base of the hole and
the setting depth mark coincides with the concrete surface.
– Use the setting machine at a speed of 450–1300 RPM to drive the anchor rod into the hole, applying moderate pressure. Switch off the setting machine
immediately when the setting depth is reached (refer to mark on the anchor rod). After setting, adhesive mortar must fill the annular gap completely,
right up to the concrete surface. Caution! Prolonged rotary action may cause mortar to be forced out of the hole, resulting in poor load values / potential
failure of fastening.
– Ensure that the specified anchor rod is used in setting the product.
Poor load values / potential failure of fastening due to inadequate borehole cleaning
– The anchor borehole must be free of dust, water, ice, oil, bitumen, chemicals or any other foreign matter or contaminants.
– Clean the borehole right before setting the anchor. Remove drilling dust and standing water from the base of the hole by blowing out well with at least 4
strokes of the Hilti blow pump, or using oil-free compressed air. When using a hollow drill bit, Hilti VC vacuum cleaner must be combined.
For diamond cored holes:
– Only use specified wire brush for cleaning the borehole. Wear-out of brushes will lead to reduction in cleaning quality and may lead to poor load values.
Please replace the brushes.
– For requirements at application temperature below 0°C, contact Hilti.
For overhead application:
Use HIT-OHC as a drip guard.
Loading or manipulation of anchor rod is not allowed within the curing time «t cure».
Warranty:
Refer to standard Hilti terms and conditions of sale for warranty information.
Failure to observe these installation instructions, use of non-Hilti anchor rods, poor or questionable concrete conditions,
or unique applications may affect the reliability or performance of the fastenings.
