Frequently Asked Questions - SB 422 HILTI
How to replace the saw blade on the Hilti SB 422?
To replace the blade, start by removing the battery. Unscrew the 2 screws on the blade cover and remove the cover. Unscrew the side handle counterclockwise to remove it. Rotate the tension lever 180° until it stops. Insert the new blade into the cutting guide and blade guides, respecting the direction of rotation (arrows). Place the blade around the pulleys, then re-engage the tension lever. Reinstall the cover and handle. Check proper operation by briefly running the saw.
How to charge the battery of the SB 422?
Use only a Hilti-approved charger for B22 batteries. Before charging, ensure the battery and charger contacts are clean and dry. Insert the battery into the charger and follow the charger instructions. Charging should occur within a temperature range of -10 °C to 45 °C.
What materials can I cut with the SB 422 band saw?
The SB 422 is designed to cut metals and plastics. Do not cut brick, concrete, aerated concrete, natural stone, or tiles. Also avoid cutting pipes that still contain liquid or gas.
What to do if the saw does not start?
First check that the anti-restart safety is activated. Make sure the battery is properly inserted and charged. Check that the saw blade is not blocked. If the battery LEDs show nothing, the battery may be defective. Consult the troubleshooting table in the manual or contact Hilti customer service.
How to clean and maintain the SB 422 saw?
Always remove the battery before cleaning. Use a soft dry brush for ventilation slots. Clean the housing with a slightly damp cloth without silicone-based cleaners. Clean contacts with a dry cloth. Regularly check for damage and proper operation of controls.
What are the essential safety instructions for the SB 422?
Always wear safety glasses, hearing protection, and gloves. Hold the saw with both hands on the insulated handles. Never stand in line with the blade. Before cutting, check for hidden electrical cables. Use only Hilti batteries and chargers.
How to interpret the battery indicators?
Briefly press the battery release button. 4 green LEDs mean 100-71% charge; 1 slow flashing green LED means less than 10%; 1 fast flashing green LED indicates a discharged battery; 1 yellow LED indicates a fault (overload, temperature); 1 fast flashing red LED means the battery is locked. Consult the manual for more details.
What is the maximum cutting depth of the SB 422 saw?
The maximum cutting depth is 63.5 mm (2.50 inches). This allows cutting tubes, profiles, and sheets of metal or plastic of that thickness.
