Bosch SDS-Max Combination Rotary Hammer (Factory Reconditioned)

Professional Performance and Maintenance Guide

This factory-reconditioned Bosch SDS-Max Combination Rotary Hammer is designed to meet the rigorous demands of construction professionals. To ensure optimal performance and longevity, we recommend the following expert practices:

Optimizing Heat Management

To prevent performance degradation during heavy-duty concrete drilling, we advise using a pulsed drilling technique. Allow the tool to run at no-load speed for 30 seconds every 15 minutes of continuous operation to facilitate internal cooling.

Structural Integrity and Care

Our reconditioned units undergo rigorous quality checks. To maintain structural integrity, ensure all external housing screws are checked for tightness before each shift. Avoid excessive side-loading, which can stress the back cover and bottom ring assemblies.

Chuck Maintenance Protocol

The SDS-Max chuck mechanism requires consistent lubrication. We recommend using a high-quality, heat-resistant grease on the shank of your bits before insertion. This prevents binding and ensures smooth operation. If the chuck becomes stiff, clean the internal locking balls with compressed air and re-apply lubricant.

Operational Clarity

Please note that this specific model does not feature an integrated LED light. For low-light environments, we recommend utilizing a dedicated magnetic work light to ensure precision and safety. This tool is optimized for masonry and concrete; for extremely hard materials like granite, we suggest using premium-grade carbide bits to reduce vibration and heat buildup.
