3. Product Overview
The Hilti HDM 500 is a manual dispenser designed for two-component adhesive cartridges. It features a durable construction and is well-balanced for improved handling during application. The dispenser accommodates different cartridge sizes through interchangeable cartridge holders.

The dispenser set typically includes the HDM 500 gun and at least one cartridge holder (e.g., black for HIT-CB 500 cartridges). Additional cartridge holders (such as the red one) can be used for other compatible adhesive types.


4. Setup
Proper setup ensures optimal performance and safety. Follow these steps to prepare your Hilti HDM 500 dispenser for use:
- Select Cartridge Holder: Choose the appropriate cartridge holder (e.g., black or red) that matches the adhesive cartridge you intend to use.
- Retract Plunger: Pull back the plunger arm of the dispenser completely. This is typically done by pressing a release button or lever near the handle and pulling the rod back.
- Open Dispenser: Press the button located on the top of the dispenser to release and pivot the front part of the dispenser open. This allows access to the cartridge chamber.
- Insert Cartridge Holder: Place the selected cartridge holder into the dispenser, ensuring it clicks securely into position.
- Insert Adhesive Cartridge: Carefully slide the adhesive cartridge into the installed cartridge holder until it is fully seated.
- Attach Mixing Nozzle: Remove the cap from the adhesive cartridge and securely screw on the static mixing nozzle provided with the adhesive. Ensure it is tightened properly to prevent leaks and ensure proper mixing.
5. Operating Instructions
Once the dispenser is set up with the adhesive cartridge and mixing nozzle, you can begin the application process:
- Purge Initial Material: Before applying to the actual workpiece, dispense a small amount of adhesive onto a scrap surface until a consistent, uniformly mixed color is observed. This ensures both components are properly mixed.
- Apply Adhesive: Position the mixing nozzle into the hole or area where the adhesive is to be applied. Squeeze the trigger repeatedly to dispense the adhesive. Maintain steady pressure for a continuous flow.
- Control Flow: The amount of adhesive dispensed is controlled by the trigger. Release the trigger to stop the flow.
- Follow Adhesive Curing Times: Refer to the adhesive manufacturer's instructions for specific curing times and working temperatures.
6. Maintenance
Regular maintenance will prolong the life of your Hilti HDM 500 dispenser:
- Cleaning: After each use, remove the adhesive cartridge and mixing nozzle. Clean any excess adhesive from the dispenser body, especially around the plunger and cartridge holder, using a suitable solvent if necessary (check adhesive manufacturer's recommendations).
- Inspection: Periodically inspect the dispenser for any signs of wear, damage, or loose components. Ensure the plunger mechanism operates smoothly.
- Storage: Store the dispenser in a clean, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
If you encounter issues with your Hilti HDM 500 dispenser, consider the following:
- Difficulty Dispensing: Ensure the plunger arm is fully retracted before inserting the cartridge. Check that the cartridge is correctly seated in the holder and the mixing nozzle is securely attached and not clogged.
- Cartridge Not Fitting: Verify that you are using the correct cartridge holder for your specific adhesive cartridge size.
- Uneven Mixing: Ensure the mixing nozzle is properly attached and that the initial purge of adhesive was sufficient to achieve a consistent mix.
For persistent issues, contact Hilti customer support or a qualified service technician.
