The operation of any power tool can result in foreign objects being thrown into your eyes, which can result in severe eye damage. Before beginning power tool operation, always wear safety goggles or safety glasses with side shields and, when needed, a full face shield. We recommend a wide vision safety mask for use over eyeglasses or standard safety glasses with side shields. Always use eye protection that is marked to comply with ANSI Z87.1.

- Become familiar with all controls and their proper operation. Know how to stop the mower and how to disengage the power in an emergency.
- In order to avoid contact with the blade or injury caused by a thrown object, stay in the operating zone behind the handles and keep children and bystanders at least 50 ft. (15 m) away from the mower while it is in operation. Stop the motor immediately if someone enters the mowing area.
- Thoroughly inspect the area where the mower is to be used. Remove all stones, sticks, wires, bones, toys, and other objects that could be tripped over or thrown by the blade. Thrown objects can cause serious personal injury.
- Plan your mowing pattern in such a way as to avoid discharging material toward roads, sidewalks, bystanders, etc. Do not discharge material against a wall or obstruction. Doing so may cause the discharged material to ricochet back toward the operator.
- Always wear proper eye protection that complies with ANSI Z87.1 in order to protect your eyes, along with hearing protection, while operating or performing any adjustment or repair. Thrown objects that ricochet can cause serious eye injury.
- Always wear a face mask or a dust mask when operating the mower in a dusty environment.
- Dress properly. Do not wear loose clothing or jewelry that can get caught in moving parts. The wearing of protective gloves and safety footwear is recommended.
- Many injuries occur as a result of the mower being pulled over the operator’s foot during a fall caused by slipping or tripping. Do not operate this mower in bare feet or while wearing sandals or lightweight (e.g., canvas) shoes. Do not hold on to the mower if you are falling. Release the handle immediately.

Soft-Start
This LI-ION mower is equipped with a “soft-start” feature. When initially starting up, the mower will take approximately 3 seconds to get up to full speed. If the mower does not initially start, remove the battery and check under the mower deck to ensure there is nothing obstructing the blade and that the blade can spin freely by hand. Even a small amount of grass on start-up will prevent the “soft start” from turning the mower on.
CAUTION
Do not attempt to override the operation of the safety lock-out button or bail lever
WARNING:
- The operation of any mower can result in foreign objects being thrown into the eyes, which can cause severe eye damage. Always wear safety glasses while operating the mower and while performing any adjustments or repairs.
- Ensure that other people and pets remain at least 50 ft. away when the mower is in use
- Remove all stones, sticks, wires, bones, and other debris that might be thrown by the rotating blades.
Cutting height adjustment
When shipped, the wheels on the mower are set to a low-cutting position. Before using the mower for the first time, raise the cutting position to the height best suited for your lawn. The average lawn should be between 1-1/2 in. to 2 in. during cool months and between 2 in. and 3-1/2 in. during hot months.
To adjust the blade height:
- To raise the blade height, grasp the height adjustment lever (L) and move it toward the back of the mower.
- To lower the blade height, grasp the height adjustment lever (L) and move it toward the front of the mower.

Mowing tips
Note: A sharp blade will greatly enhance the performance of the mower, especially when cutting high grass. Be sure to check the blade and sharpen it at least once per year.
- Verify that the lawn is free of stones, sticks, wires, and other objects that could damage the blades or the motor. These objects could be accidentally thrown by the mower in any direction and could cause serious personal injury to the operator and to others. In order to prevent electric shock, do not operate the mower in damp or wet conditions.
- Do not mow in circles. Travel back and forth across the lawn.
- When cutting thick grass, reduce walking speed in order to allow for a more effective cut and a proper discharge of the clippings.
- For a healthy lawn, always cut off one-third or less of the total length of the grass. The average lawn should be approximately 1-1/2 to 2 in.(3,8cm to 5cm) long during cool months, and between 2 in. to 3-1/4 in.(5cm to 8,3cm) long during hot months. If there is growth, the lawn should be cut in the fall.
Mulching tips
Note: Inspect the area where the mower is to be used and remove all stones, sticks, wires, bones, and other debris that might be thrown by the rotating blade.
- Release the switch to turn the mower OFF when crossing any graveled area (stones can be thrown by the blade).
- Set the mower to the highest cutting height when mowing on uneven ground or in tall weeds.
- For effective mulching, do not cut wet grass because it tends to stick to the underside of the deck, preventing proper mulching of grass clippings. New or thick grass may require a narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing has been delayed and the grass has been allowed to grow longer than 4 in., mow the lawn twice in order to reduce the grass height to a maximum of 3-1/4 in.
- Walk at a steady pace. Overlap the cutting rows. Do not let the grass get too tall. If the grass gets too long, start at the highest cutting position and work down to the desired cutting height.
WARNING
If you strike a foreign object, stop the motor and remove the battery. Thoroughly inspect the mower for any damage. Repair any damage before operating the mower. Excessive vibration of the mower during operation is an indication of damage. Thoroughly inspect the mower and repair any damage before operating the mower.
Emptying the grass catcher bag
- Stop the mower, allow the blades to completely stop, and remove the battery.
- Lift the rear discharge cover.
- Lift the grass catcher bag by its handle to remove it from the mower.
- Empty grass clippings.
- Lift the rear discharge cover and reinstall the grass catcher bag as described earlier in this manual.
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.
Use only a Kobalt replacement blade. (Item #0535383, sold separately).
- Remove the battery.
- While wearing leather padded gloves, wedge a block of wood between the blade and the mower deck in order to prevent the blade from turning when the nut is being removed.
- Using a 15 mm wrench or socket (not included), loosen the blade nut and remove the blade. Turn the nut counterclockwise to loosen it and clockwise to tighten it.
- Remove the blade nut, the square washer, the insulator washer, and the blade.
Cleaning the mower
WARNING
- To reduce the risk of electric shock, do not expose the mower to water.
- The underside of the mower deck should be cleaned after each use, as grass clippings, leaves, dirt, and other debris will accumulate, causing rust and corrosion.
- Remove any buildup of grass and leaves on or around the motor cover (do not use water). Wipe the mower clean with a dry cloth occasionally.
- If debris builds up on the underside of the unit while in use, stop the motor and disconnect it from the power supply. Tilt the mower forward, or on its side, and scrape it clean with an appropriate tool.
