This document describes the PowerSmart 21" 80V Cordless Lawn Mower, model DB2821, a battery-powered device designed for residential lawn care. It is a walk-behind mower that uses an 80V Lithium-ion battery.
The PowerSmart 21" 80V Cordless Lawn Mower is designed to cut grass efficiently and safely. It operates using an 80V Lithium-ion battery, providing cordless convenience. The mower features a 21-inch cutting width, allowing for efficient coverage of medium to large lawns. It includes a grass catcher bag for collecting clippings, and also offers a side discharge chute option. The mower is equipped with a "Soft-start" feature, which allows it to gradually ramp up to full speed, enhancing user control and safety. The cutting height is adjustable to six positions, enabling users to customize the cut based on grass type and desired lawn appearance. The handle is foldable for compact storage.
The mower uses an 80V Lithium-ion battery, which can be fully charged in approximately 90 minutes. The no-load speed of 3000 RPM indicates a powerful motor capable of handling various grass conditions. The 21-inch cutting width is suitable for residential use, and the 15.8-gallon grass catcher capacity reduces the frequency of emptying. The different wheel sizes (7-inch front, 8-inch rear) are designed to improve maneuverability and stability.
The PowerSmart lawn mower is designed for ease of use and safety. Starting and Stopping: To start the mower, the user must press and hold the starter button (1) and then pull the switch lever (2) towards the handle. To stop, the user simply releases the switch lever (2). The "Soft-start" feature ensures a gradual power-up. Handle Assembly: The mower features a foldable handle for compact storage. The lower and upper tubes of the handle are attached and secured with knobs. A cable clip is used to secure the cable to the lower tube. Side Discharge Chute: The mower can be converted to side discharge by lifting the spring-loaded discharge cover and sliding two hooks of the side discharge chute under the hinge pin and lower the spring on the side discharge cover. Grass Catcher: To attach the grass catcher, the user lifts the rear discharge door, places the grass catcher into the slots in the handle brackets, and releases the rear discharge door so it rests on the grass catcher. Battery Installation and Removal: The battery pack is installed by lifting the battery door, placing the battery pack on the mower, aligning the guided ribs with the battery port, and making sure the latch on the bottom of the battery pack snaps into place. The safety key is then inserted, and the door is closed. To remove the battery, the user releases the power lever to stop the product, removes the safety key, presses and holds the battery latch button, and removes the battery pack. Cutting Height Adjustment: The cutting height can be adjusted to six positions. To raise the blade height, the user grasps the Front height adjustment lever (1) and Rear height adjustment lever (2) and moves them toward the front of the mower. To lower the blade height, the user grasps the levers and moves them toward the back of the mower. Mowing Tips: The manual provides tips for effective mowing, such as verifying that the lawn is free of stones, sticks, wires, and other objects, not mowing in circles, and cutting thick grass by reducing walking speed. For a healthy lawn, it's recommended to cut off one-third or less of the total length of the grass. Mulching Tips: The mower can be used for mulching. Users can release the switch to turn the mower OFF when crossing any graveled area, set the mower to the highest cutting height when mowing on uneven ground or in tall weeds, and use proper mulching techniques for effective results. Emptying the Grass Catcher Bag: To empty the grass catcher bag, the user stops the mower, allows the blades to completely stop, removes the battery, lifts the rear chute cover, lifts the grass catcher bag by its handle, and empties the clippings. The bag is then re-installed. Slope Operation: The manual provides detailed instructions and warnings for operating the mower on slopes, emphasizing the importance of caution and proper technique to prevent accidents. It advises against mowing wet or damp grass on slopes and provides a visual guide for determining a safe slope angle (not exceeding 15 degrees).
Regular maintenance is crucial for the longevity and safe operation of the mower. Cleaning the Mower: The mower should be cleaned after each use to prevent rust and corrosion. Users should remove any build-up of grass and leaves from around the motor cover and wipe the mower clean with a dry cloth. If debris builds up on the underside, the mower should be disconnected from the battery, tilted forward or on its side, and scraped clean. Storing the Mower: For storage, the mower should be cleaned, the blade inspected and sharpened or replaced, and lubricated. It should be stored in a dry, clean location, away from corrosive materials, fertilizers, or rock salt. The mower should not be stored in a wet or damp environment. The handle can be folded for compact storage. The battery should be removed and stored in a secure location out of reach of children. The battery should be charged every two weeks when not in use to increase its life. Service: For servicing, only replacement parts available from the manufacturer should be used. Users can call the toll-free helpline for assistance. Regular checks include inspecting the blade and motor mounting bolts for proper tightness, maintaining clean and free-of-grease handles, and checking for fire hazards. The grass catcher components and trail shield should be inspected for wear and damage. Battery & Charger: The manual provides extensive safety rules for battery and charger use, including warnings against crushing, dropping, or damaging the battery, exposing it to extreme temperatures, or immersing it in liquids. It also details proper care for the battery, such as keeping it dry and clean, and avoiding mutilation. For off-season storage, the battery should be stored in a 30%-50% charged condition and charged every two months. Charger safety rules emphasize not abusing the charger cord and immediately replacing damaged chargers. Environmental Safety: The manual highlights the importance of environmentally safe battery disposal, stating that the batteries contain toxic and corrosive materials (Lithium-ion) and must be disposed of properly at a facility that accepts lithium-ion batteries. Users are instructed not to attempt to remove or destroy any components of the battery pack, open the battery pack, or incinerate batteries. They should not dispose of batteries in regular household trash but at a certified recycling or disposal center.
