How to use

First, fit the mortar stirrer to the drive shaft of the Einhell GP-EA 18/150 Li BL according to the drill/auger attachment instructions for your machine. After drilling the post holes with the auger, insert the mortar stirrer into the mixed mortar or concrete and run the cordless earth auger at low to medium speed to achieve a uniform consistency. Lift and move the stirrer slightly while mixing to avoid trapping air; stop and clean the stirrer after use to prevent hardening of material on the blades.

Recommendations

Use personal protective equipment (gloves, eye protection) and follow the cordless earth auger manufacturer’s safety instructions. Mix small batches to avoid overloading the motor, and clean the stirrer immediately after use to maintain performance and service life.
