Care and Maintenance

Replacing the cutting blade

⚠️ WARNING: Always protect your hands by wearing heavy gloves and/or wrapping the cutting edges with rags or other materials when performing any maintenance on the blades. Always remove the battery when servicing or transporting the mower.

To re-install the blade, position the blade with the cutting edges toward the ground. Assemble the blade nut, the square washer, and the insulator washer as shown. Using a 15 mm socket or wrench, turn the blade nut clockwise in order to secure the blade.

Note: Be sure to replace the parts in the exact order in which they were removed. When installing the cutting blade, verify that it is installed with the curved ends pointing toward the mower deck, and not toward the ground. Refer to the schematic drawing on the right.

⚠️ WARNING: When servicing the mower, use only replacement parts that are available from the manufacturer. In order to obtain replacement parts, call 1-866-456-8934. The use of parts that do not meet the original equipment specifications may lead to improper performance, and may compromise safety. Before cleaning, repairing, or inspecting, verify that the blade and all moving parts have come to a complete stop. Remove the battery when making any adjustments or when any of the four wheels must be lifted off the ground. Follow the instructions for lubricating and changing accessories. Keep the handles dry, clean, and free of oil and grease. In order to reduce the risk of fire, keep the motor free of grass, leaves, and debris build-up. Check the blade and motor mounting bolts for proper tightness frequently. Visually inspect blade for damage (e.g., bent, cracked, or worn). For best and safest performance, maintain the mower with care. Keep the mower blade sharp and clean. Mower blades are sharp and can cut. Wrap the blades or wear gloves and use extra caution when servicing. Keep all nuts, bolts, and screws tight in order to be sure that the equipment is in safe working condition. Never tamper with safety devices. Check them regularly for proper operation. After striking a foreign object, stop the motor. Thoroughly inspect the mower for any damage.
