If the overload protector is actuated, the on-off button must be released. Press the on-off button to restart the product.
The battery pack has overheat protection. Excessive temperatures will cause the battery to stop powering the product. If the battery pack is too warm, allow it to cool down before resuming operation. If the product still does not work, recharge the battery pack.
NOTE: The battery pack LED indicator will not work if the battery protection feature has caused the battery pack to stop powering the product. Release the on-off button or remove the battery pack from the product and the battery pack LED indicator will resume normal function.
Tilt Protection
If the product is tilted beyond 45°, for about 7 seconds, the product will stop. The product will not function if the tilt angle limit is exceeded or if the product is in the vertical storage position.
Telescopic Handle
The product is equipped with a telescopic handle that can be adjusted for storage and operation. The telescopic handle must be fully extended when setting up the product for use.
NOTE: The product will not function if the telescopic handle is not fully extended and the two latches are not in the correct position.
General Mowing Tips
The run time of the battery depends on the condition, length, and density of the grass. Adjust the cutting height of the lawn mower to suit the current condition of the lawn.
Grass conditions | Suggested height adjustment | Coverage (maximum) |
---|---|---|
Thin / Dry | 4 (First pass) / 3-2 (Succeeding passes) | 350 m² (with RB18L60A x 1 battery) |
Medium / Dense | 5 (First pass) / 4-3 (Succeeding passes) | 300 m² (with RB18L60A x 1 battery) |
Grass conditions | Suggested height adjustment | Coverage (maximum) | ||
---|---|---|---|---|
First pass | Succeeding passes | RB18L50 x 1 | RB18L50 x 2 | |
Thin / Dry | 4 | 3-2 | 250 m² | 500 m² |
Medium / Dense | 5 | 4-3 | 200 m² | 400 m² |
- For best performance, always cut off one-third or less of the total height of the grass.
- When cutting long grass, reduce walking speed to allow for more effective cutting and a proper discharge of the clippings.
- Do not cut wet grass. Wet grass sticks to the underside of the deck and prevents proper collection or discharge of grass clippings.
- New or thick grass may require a higher cutting height.
- To collect the grass cuttings for disposal, remove the mulching plug and fit the grass catcher, making sure the rear door is properly closed. Empty the grass catcher regularly; otherwise, the discharge chute will become blocked with grass clippings.
- If you are making a light cut and wish for the grass cuttings to remain on the lawn, fit the mulching plug and close the rear door to cover the discharge opening. It is not necessary to fit the grass catcher in this case.
- The product is designed to operate and cut most effectively when moving forwards.
- A higher cutting height extends the run time of the battery pack.
- Use the LED fuel gauge as an indication guide only. The gauge may not reflect the actual individual 18 V battery charge level. Manually measure the battery pack individually to accurately check the remaining charge level.
Battery Charge Indicator:
- 16-100%: Green LED
- 0-15%: Red LED
NOTE: The flashing red LED in the LED fuel gauge indicates mower overload.

Risk Reduction
It has been reported that vibrations from handheld tools may contribute to a condition called Raynaud's Syndrome. Symptoms may include tingling, numbness and blanching of the fingers, usually apparent upon exposure to cold. Hereditary factors, exposure to cold and dampness, diet, smoking and work practices are all thought to contribute to the development of these symptoms. There are measures that can be taken by the operator to possibly reduce the effects of vibration:
- Keep your body warm in cold weather. When operating the product, wear gloves to keep the hands and wrists warm. It is reported that cold weather is a major factor contributing to Raynaud's Syndrome.
- After each period of operation, exercise to increase blood circulation.
- Take frequent work breaks. Limit the amount of exposure per day.
If you experience any of the symptoms of this condition, immediately discontinue use and see your physician.
⚠️ WARNING: Injuries may be caused, or aggravated, by prolonged use of a tool. When using any tool for prolonged periods, ensure you take regular breaks.
