Frequently Asked Questions - HDM 330 HILTI

How to insert a foil cartridge into the cartridge holder?

Place the foil cartridge into the cartridge holder following the instructions in the cartridge's manual. Make sure the color of the cartridge holder matches the cartridge (black for black or white cartridge, red for red cartridge).

How to change the mixing nozzle?

To change the mixing nozzle, first press the unlocking button to release pressure. Unscrew the used nozzle and screw on a new static mixing nozzle. Use a new nozzle for each application.

What to do if the trigger lever is difficult to operate?

This may be due to a cartridge that is too cold. Increase the temperature of the cartridge (refer to the cartridge's manual). If the problem persists, use a device suitable for the job.

How to clean the injection dispenser?

Clean the exterior with a slightly damp cloth. Do not use steam jet, running water, or solvent. Regularly oil the push rods. Remove any mortar residues quickly before they harden.

What types of cartridges are compatible with the HDM 330?

The HDM 330 is designed exclusively for Hilti 330 ml (11.1 fl.oz) foil cartridges with the HIT CB 330 or HIT CR 330 cartridge holders.

How to prevent mortar from continuing to come out after dosing?

Press the unlocking button to stop extrusion. This prevents the mortar from continuing to flow. Remember to remove the cartridge before cleaning.

What to do if the cartridge holder does not click into place?

Check that the cartridge is fully inserted and that the push rod is fully retracted. Clean the locking lugs if they are dirty. Replace the cartridge holder if necessary.

How to discard the first extruded mortar?

After screwing on a new mixing nozzle, pull the trigger lever completely several times (2 presses recommended). The mortar extruded from the first presses must be discarded as it is not suitable for the application.

What protective equipment is recommended?

Always wear a tight-fitting eye/face protection, gloves, and protective clothing. Persons nearby must also wear protective equipment.

Where to find spare parts for the HDM 330?

Use only original Hilti accessories and tools. Contact your local Hilti partner or Hilti service center to order parts such as cartridge holders or mixing nozzles.
