User Instructions
- Try, where possible, to run at the recommended RPM for the product (please see speed chart)
- Using an appropriate cutting lubricant will reduce drilling time and improve tool life. Try the Armeg Cutting Compound (ECC002)
- Ensure accessory is cutting efficiently before applying pressure to avoid breakage at start-up
- Pilot drilling with a smaller diameter first will reduce drilling time and improve tool wear
- Try and keep ratcheting / impact function to a minimum when using an impact driver. This may involve reducing pressure momentarily
- Do not use on SDS Hammer action
