Ryobi Ryobi RY40260 40V Expand-It Cordless String Trimmer MOTOR STALL Error Fix: Motor Bogs Down in Thick Vegetation

Error code MOTOR STALL on the Ryobi Ryobi RY40260 40V Expand-It Cordless String Trimmer means: Motor Bogs Down in Thick Vegetation. The trimmer motor slows significantly or stalls when cutting through thick weeds, brush, or overgrown grass. Battery-powered trimmers have less sustained torque than gas trimmers and are more susceptible to bogging in heavy vegetation. Solutions: Use a sweeping motion rather than plunging the head into thick growth — let the line tips do the cutting. Cut in stages — take a little off the top first, then lower for a second pass rather than trying to cut to ground level in one pass. Use the correct line — thicker line (0.080" or 0.095" if supported) handles heavy vegetation better than thin line. Keep the line at the optimal length — too long and the motor works harder; too short and you lose cutting diameter. Use a fully charged battery — motor torque decreases as battery voltage drops. If the motor stalls frequently during normal-weight trimming, the motor or controller may be degraded. Try a different battery first — if performance improves with a fresh battery, the original battery may be degraded. For very thick brush, consider using a Ryobi Expand-It brush cutter attachment instead of the string trimmer head.
