The default start time of the daily working schedule is 08:00(GMT)/09:00(BST) for 8 hours. In the following days, the mower will start again at the same time for the selected working duration. If AMB16-400 is not mowing according to the expected schedule, check the information below. 

Factors that may affect AMB16-400 mowing schedule: 

• - If the mower could not connect correctly to GPS, the time data cannot be saved correctly. Check for a solid green GPS light. 
• - If AMB16 was sent back to the charging station using the "home" button, it will not mow again until the next day. 
• - If the mower rain sensor is triggered, the mower will wait for 2 hours after the sensor has dried. 
• - If the Stop button is pressed on the mower during the charging process, or the battery is not fully charged, AMB16-400 will stay on the charging station. Avoid turning off the charging station, or if the power outlet is on a timer, allow the station to power on at least 1 hour before mowing start time. 
• - If it is dark when the mower is scheduled to start mowing, it will remain on the charging station until it is light enough to operate. 

To change the working time, perform the following steps at the time of day that you wish AMB16-400 to begin mowing: 

1. 1) Remove the mower from the charging station. 
2. 2) Enter PIN and press On/START. For everyday mowing: Long press the schedule setting button for 3 seconds. The schedule setting indicator will flash green. For every other day mowing: Long Press the schedule for 6 seconds. The schedule setting indicator will flash yellow. 
3. 3) Press the schedule setting button to select the desired working time. 
4. 4) Press the START/ON button to confirm. The corresponding schedule setting indicator will be green or yellow solid. The mower will start at this time every day or every other day. 

Please check that the charging station is set up according to the set up instructions.

Ensure that the orange strip is clearly visible to AMB16-400.

Ensure the charging station is set up on flat ground. If the charging station is set up on a slope, this may affect the visibility of the orange strips.

Ensure the charging station is positioned 90 degrees to the edge of the lawn, with the entrance to the station facing into the lawn.

There must also be 2 meters clearance to both sides of the charging station, otherwise AMB16-400 will not be able to trim around the base plate of the charging station.

This can occur in the first week or two of running a random pattern mower, however this will even out over time to leave a beautiful finish and healthy grass.

To make uncut grass much less obvious from first install, it is advisable to first cut the grass with a push lawnmower to the desired length, then let AMB16-400 maintain it. If this is not possible, it is recommended to raise the robot mower height of cut to lightly trim the grass. The height of cut can be reduced daily over a period of one to two weeks until the grass is the desired length.

It is not advisable to cut more than 20mm of the grass length with AMB16-400 (e.g. do not try to cut 60mm long grass down to 20mm). This will affect the battery run time and cause build-up of grass clippings on the underside of the mower.

The lawn may also look uneven. As AMB16-400 becomes established in a schedule, the grass will become a uniform length.

AMB16-400 works best with visually distinctive borders. If your lawn has edges that are not visually distinctive, for example:

1) borders which may have grass-like low growing plants
2) borders which have many weeds growing in them
3) mossy or weedy gravel or wood chippings
4) paths which have grass or weeds growing through gaps

AMB16-400 may mistake these areas for lawn and try to mow in these areas. Try to ensure that paths and borders are free from weeds and have a clear contrast or raised edge.

AMB16-400 is supplied with 5m of magnetic No-Go strip which can be used to prevent the mower entering certain areas. Use the No-Go strip in areas which may be identified as lawn.

AMB16-400 has an on-board GPS sensor which it uses to get close to the base station. Once the mower is close to the station, it uses the camera to navigate back on to the dock.

If AMB16-400 cannot get a clear GPS signal, navigating back to the charging station will take longer.

AMB16-400 must be started for the first time from the charging station, to enable to mower to learn the location of the charging station. The mower may take up to 3 minutes to position correctly, the GPS indicator will flash during this time.

If the mower cannot connect successfully to GPS, move the charging station to an area away from tall buildings and trees.

Do not position the charging station in between buildings or under metal covers.

This happens when AMB16-400 is unable to detect grass.

If the lawn is brown or patchy, the camera may not recognise it as grass.

Move the mower to an area where grass is clearly present.

The grass is cut using three small sharp blades and the clippings are returned to the lawn surface where the nutrients contained in them fertilise the soil.

This means stronger, healthier grass with less need for supplemental fertiliser and has the added bonus of helping the lawn retain water in dry periods. It also means no grass clippings to dispose of or compost.

Provided that AMB16-400 is used regularly, the grass clippings are not visible to the eye.

No, AMB16-400 is not compatible with the MX 24V battery system.

AMB16-400 is supplied with a built in battery, making it IPX5 rated.

Choose from cutting heights of between 20mm and 60mm for a neat looking lawn by adjusting the dial on the top of AMB16-400.

For best performance and to encourage healthy lawn growth use 60mm for longer grass and after regular mowing, gradually reduce the cutting height to your desired length.

It is possible to use AMB16-400 on lawns with a pond, however it is strongly recommended that the pond is surrounded by No-Go magnetic strip, or a raised barrier to safeguard against the mower falling in.

We recommend either a raised edge or a paved/gravel border at least 35cm wide surrounding the pond if no magnetic strip is installed.

Water damaged mowers are not covered under guarantee.

This could be due to one of the following reasons:
- If AMB16-400 was sent back to the charging station using the "home" button, it will not mow again until the next day.
- If the mower rain sensor is triggered, AMB16-400 will wait until 2 hours after the sensor has dried.
- If the STOP button is pressed on the mower during the charging process, or the battery is not fully charged, the mower will stay on the charging station.
- If it is dark when the mower is scheduled to start mowing, it will remain on the charging station until it is light enough to operate.
