- Rear Collection (Bagging): Ensure the grass collection bag is properly attached and the mulching plug and side discharge chute are removed.
- Mulching: Insert the mulching plug into the rear discharge opening. Remove the grass collection bag and side discharge chute. The mower will finely cut grass clippings and return them to the lawn as natural fertilizer.
- Side Discharge: Attach the side discharge chute to the side of the mower. Remove the grass collection bag and mulching plug. This mode is useful for cutting taller grass where bagging is not desired.
Self-Propelled Feature (if applicable)
This model features wheel drive. To engage the self-propelled function, pull the drive lever towards the handle while the mower is running. Release the lever to disengage.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your lawn mower. Always remove the safety key and battery before performing any maintenance.
Cleaning
- After each use, clean the underside of the mower deck to prevent grass buildup. Use a brush or scraper.
- Wipe down the exterior of the mower with a damp cloth. Do not use water jets or high-pressure cleaners.
- Clean the grass collection bag regularly.
Blade Care
- Inspect the blade regularly for sharpness and damage. A dull blade tears grass, leading to an unhealthy lawn.
- If the blade is dull, have it sharpened by a qualified service center or replace it with a genuine Greenworks replacement blade.
- Ensure the blade is balanced after sharpening to prevent vibration.
Battery and Charger Storage
- Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
- Do not store batteries in a discharged state for extended periods. Charge them periodically.
- Store the charger indoors in a dry environment.
