The Ryobi RM300E is not charging because the battery pack may be defective. A flashing green light on the mower and no green light on the charger indicates a charging issue. Try resetting the charger or reinserting the battery. If the issue repeats, test with a different battery. If the other battery charges normally, the original battery is likely defective and should be disposed of properly.

installed new batteries turned key on charging indicates two red bars mower will not move

If the Ryobi RM300E mower has two red bars on the charger after installing new batteries and won't move, the battery charge may be too low. The manual states that when the battery charge indicator is in the red zone, the blades will shut off, and the mower may become stranded. The solution is to turn the key switch to the off position and push the mower back to the charging location. Ensure the batteries are properly connected and fully charged before use.

The cutting on the Ryobi RM300E mower disengages after starting for the following possible reasons:
1. Operator is not fully seated: Fully sit down on the seat to ensure the safety interlock system is engaged. 2. Blade engage knob is down: Pull up the blade engage knob to activate the blades. 3. Battery charge is low: Charge the battery to ensure sufficient power. 4. Debris build-up under the mower deck: Clean the underside of the mower deck to prevent interference. 5. Side discharge interlock switch is not pressed fully: Ensure the side discharge chute is fully pressed down to engage the interlock switch.
