All Operators Must Read These Instructions Before Use
Always follow these safety guidelines. Failure to do so may result in serious bodily injury or death.
General Safety WARNINGS!
When using this cordless lawn mower, basic safety precautions should always be followed to reduce the risk of fire, electric shock and personal injury. These precautions include:
Do not operate without the entire grass collection bag, discharge guard, rear guard or other safety protective devices in place and in proper working order.
The use of any other accessory or attachment might increase the risk of injury.
To reduce the risk of injury, inspect the grass collection bag assembly frequently and replace with recommended replacement if there are signs of wear or deterioration. Before using the mower, take the time to familiarize yourself with the controls, especially how to stop the mower in an emergency. The only individuals who should use the mower are those who have a thorough understanding of the instructions and who knows how to operate the machine. Children should never be allowed access to the mower. Retain this manual for future reference and reread it at the start of each mowing season.
Contact with moving parts may cause entanglement, dismemberment or other serious bodily injury. Always keep body parts (i.e. hands, feet) a safe distance away from moving parts. Ensure all covers and guards are securely in place before use. Hot surfaces (i.e. the motor) may ignite flammable or combustible items and cause a fire or explosion, which can result in serious bodily injury. Keep the mower a safe distance away from flammable or combustible items until surfaces that are hot have completely cooled. Do not store the mower near flammable or combustible items.
A damaged blade or worn blade nut may break off the mower assembly and cause serious injury. Replace the damaged blade or blade nut before using the mower.

Electrical Safety
Battery + Charger Safety Instructions
We pay a great deal of attention to the design of every battery pack to ensure that we supply you with batteries that are safe, durable and have a high energy density. The battery cells have a wide range of safety devices. Each individual cell is initially formatted and its electrical characteristic curves are recorded. This data is then used exclusively to be able to assemble the best possible battery packs. Despite all the safety precautions, caution must always be exercised when handling batteries. The following points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are used. Incorrect handling of the battery pack can cause cell damage.
Analyses confirm that incorrect use and poor care of high-performance batteries are the main factors responsible for personal and/or product damage.
Use only approved replacement batteries; other batteries may damage the lawn mower and cause it to malfunction, which can lead to serious personal injury.
To reduce the risk of injury, charge the 24V iON+ lithium-ion battery packs only in the designated 24V iON+ lithium-ion charger. Other types of chargers present risk of fire, personal injury and damage. Do not wire the battery packs to a power supply plug or car cigarette lighter. Such misuse will permanently disable or damage the battery packs.

Carton Contents
The equipment and packaging material are not toys. Do not let children play with plastic bags, foils, or small parts. These items can be swallowed and pose a suffocation risk!
The equipment is powered by two lithium-ion batteries. The battery packs are completely sealed and maintenance free.
The cordless lawn mower can only be powered by both of the batteries together. One battery cannot provide sufficient power to the tool. Make sure to use two batteries of the same voltage and the same capacity. Using the tool with batteries of different capacities will cause damage to the batteries.
Before first use, the batteries require 1 hr 50 min charge time to be fully charged. When the batteries are at low capacity, recharge for 1 hr 50 min again before resuming operation.
Battery Charge Level Indicator
The battery packs are equipped with a push button for checking the charge level. Simply press the push button to read off the battery charge level from the LEDs of the battery indicator:
![]() | |
Lights | Light Indicators |
![]() | Charge level button |
![]() | The battery is at 30% capacity and requires charging |
![]() | The battery is at 60% capacity and requires charging soon |
![]() | The battery is at full capacity |
NOTE: If the charge level button does not appear to be working, insert the batteries into the charger and charge as needed.
NOTE: Immediately after using the battery pack, the charge level button may display a lower charge than it will if checked a few minutes later. The battery cells "recover" some of their charge after resting.
Charge only 24V iON+ lithium-ion battery packs with their compatible 24V iON+ lithium-ion charger. Other types of batteries may cause personal injury and damage. To reduce the risk of electric shock, do not allow water to flow into the charger's AC/DC plug.
When to Charge the iON+ 24VBAT Lithium-Ion Batteries
NOTE: The iON+ 24VBAT lithium-ion battery packs do not develop a "memory" when charged after only a partial discharge. Therefore, it is not necessary to run down the battery packs before placing them into the charger.
Charging the Batteries
FIRE HAZARD. When removing the batteries from the charger, be sure to unplug the charger from the outlet first, then remove the batteries from the charger.
This charger does not automatically turn off when the batteries are fully charged. Please take care not to leave the batteries in the charger. Switch off or unplug the charger at the mains when charging is complete.
Never allow the battery packs to become fully discharged as this will cause irreversible damage to the batteries.
Charging a Hot or Cold Battery Pack
The green indicator lights on the charger base indicates that the battery packs' temperatures are outside the charging range. Once the packs are within the acceptable range, normal charging will take place and the red light will be continuous. Hot or cold battery packs may take longer to charge.

NOTE: When using the side discharge chute, do not assemble the grass collection bag. Insert the mulching plug in the rear discharge opening.
Mulching Plug Assembly + Fitting
Your mower is equipped with a mulching plug to allow the blade to cut and recut the grass for finer clippings.
NOTE: When using the mulching plug, do not assemble the grass collection bag or the side discharge chute.
NOTE: When the grass collection bag is not attached, the mulching plug must be inserted in the rear discharge opening.
This lawn mower is intended for private residential use to cut grass in small lawns and gardens. This lawn mower is not intended to cut grass in public parks, playing fields, farms or forests. Do not use this lawn mower for any application other than that for which it is intended.
Adjusting the Cutting Height
This cordless lawn mower is equipped with a 7-position height adjustment lever to tailor grass cutting heights from 1.2 in. to 3.5 in. (30 mm to 90 mm). To change the cutting height of the grass, follow the instructions below.
Before making these adjustments, remove the batteries and the safety key from the lawn mower and wait until the rotating blade has come to a complete standstill.
ALWAYS FOLLOW ALL SAFETY PRECAUTIONS AND RECOMMENDATIONS LISTED PREVIOUSLY IN THIS MANUAL.
Starting + Stopping
Before switching on the mower, make sure that it is not in contact with any foreign objects. Keep your hands and feet a safe distance away from the rotating mower blade and the ejector opening. Failure to comply with these warnings can result in severe personal injury.
Do not start the mower in tall grass.
The mower blade will continue to rotate for a brief period after the unit has been switched off. Do not tilt or carry the unit while the motor is still running and do not touch the blade while it is still rotating. Failure to comply could result in severe personal injury.
Using the Self-Propelled System
The cordless lawn mower is equipped with a variable-speed self-propelled system, which is independent and can be operated without the blade rotation. For example, when you have completed cutting your lawn, you can use the self-propelled system to propel the mower back to your storage location without blade rotation. Or you may choose to operate the mower as a non-self-propelled mower to maximize battery run time. To operate the self-propelled system without blade rotation, push and hold the self-propel lever to the handle. To turn off the self-propel system, release the self-propel lever (Fig. 16). The system has variable speeds. Adjust the speed by turning the speed-adjusting dial as shown (Fig. 16).

Mowing Tips
Inspect the area prior to mowing and remove all the stones, sticks, wires and other foreign objects that could be picked up and thrown by the rotating blade. Failure to comply not only will damage the mower blade, but can also lead to serious personal injury.
Before cleaning, repairing or inspecting the mower, stop the machine, remove the batteries and the safety key. Verify that all moving parts have come to a complete stop.
General
Blade Maintenance
The mower blade is sharp and can cause severe personal injury if handled incorrectly. Wrap the blade or wear protective gloves, and use extra caution when handling. The steel blade is designed to provide a fine cut in long or tough grass. Deterioration in the quality of cut indicates blade wear or damage. Follow these steps to determine if the blade needs to be resharpened or replaced:
