Maintenance

Introduction

For better operating reliability and longer service life: check and clean the product regularly and replace worn parts if necessary. All maintenance and servicing must be done according to GARDENA's instructions.
It is important that the blade disc rotates easily. The edges of the blades should not be damaged. The lifetime of the blades varies immensely and depends for instance on:

• Operating time and size of the work area.
• Type of grass and seasonal growth.
• Soil, sand and use of fertilizers.
• The presence of objects such as, toys, tools, stones, roots and the like.

The normal life is 3 to 6 weeks when used under favorable conditions. Refer to Replace the blades on how to replace the blades.

Wear protective gloves.

Note: Working with blunt blades gives a poorer mowing result. The grass is not cut cleanly and more energy is needed, resulting in the product not being able to maintain such a large area.

Clean the product

It is important to keep the product clean. A product with large amounts of grass stuck to it will not cope as well with slopes. It is recommended to clean using a brush.
GARDENA offers a special cleaning and maintenance kit as an accessory. Contact your GARDENA central service.

Never use a high-pressure washer to clean the product. Never use solvents for cleaning.

Chassis and blade disc

Inspect the blade disc and blades once a week.

1. Set the Main switch to position 0.
2. Lift the product onto its side.
3. Clean the blade disc and chassis using for example a dish brush. At the same time, check that the blade disc rotates freely in relation to the foot guard. Also, check that the blades are intact and can pivot freely.
   

Chassis

Clean the underside of the chassis. Brush or wipe with a damp cloth.

Wheels

Clean around the front wheels and rear wheel as well as the rear wheel bracket. Grass on the wheels can impact on how the product performs in slopes.

Cover

Use a damp, soft sponge or cloth to clean the cover. If the cover is very dirty it may be necessary to use a soap solution or washing-up liquid

Charging station

Clean the charging station regularly from grass, leaves, twigs and other objects that may impede docking.

Use the plug to disconnect the charging station before any maintenance, or cleaning of charging station or power supply.

Replace the blades

Use blades and screws of the right type. GARDENA can only guarantee safety when using original blades. Only replacing the blades and reusing the screw can result in a screw wearing during mowing. The blades can then be propelled from under the body and cause serious injury.

Replace worn or damaged parts for safety reasons. Even if the blades are intact, they should be replaced on a regular basis for the best mowing result and low energy usage. All 3 blades and screws must be replaced at the same time to obtain a balanced cutting system. Use GARDENA original blades embossed with the crowned H-mark logotype.

To replace the blades

1. Set the main switch to position 0.
   
2. Turn the product upside down. Place the product on a soft and clean surface to avoid scratching the body and the hatch.
3. Remove the 3 screws. Use a straight slot or cross-tip screwdriver.
   
4. Remove each blade and screw.
5. Fasten new blades and screws.
6. Check that the blades can pivot freely.

Software update

If service is done by a local GARDENA representative then available software updates are downloaded to the product by the service technician. However, owners of GARDENA products can download regular software updates from the GARDENA website and install them on their product. Registered users will be notified of this by email. To download new software, the product is connected to a computer using the accompanying USB cable.

1. Connect the USB cable between your computer and the product.
   1. Remove the service outlet plug on the bottom of the product. The service outlet is located beside the main switch.
   2. Connect the USB cable to the computer's USB ports.

2. Set the main switch to position 1 and place the product standing on all wheels.
3. Follow the software update instructions from your received email.
4. When the product programming is completed disconnect the USB cable and fit the service outlet plug. If the seal on the service outlet plug is visibly damaged, the entire plug must be replaced. Make sure the plug is locked completely.

Battery

Only charge the product using a charging station which is intended for it. Incorrect use may result in electric shock, overheating or leakage of corrosive liquid from the battery. In the event of leakage of electrolyte flush with water and seek medical help if it comes in contact with the eyes etc.

Use only original batteries recommended by the manufacturer. Product safety cannot be guaranteed with other batteries. Do not use nonrechargeable batteries.

The battery must be charged fully before winter storage. If the battery is not fully charged it can be damaged and in certain cases be rendered useless.

If the operating times for the product are shorter than normal between charges, this indicates that the battery is getting old and eventually needs replacing. The battery is fine as long as the product maintains a well-cut lawn.

Note: Battery life is dependent on the length of the season and how many hours a day the product is operating. A long season or many hours of use a day means that the battery must be replaced more regularly.

To replace the battery

Use only original batteries recommended by the manufacturer. Product safety cannot be guaranteed with other batteries. Do not use nonrechargeable batteries. The appliance must be disconnected from the supply mains when removing the battery.

1. Set the main switch to position 0.

The product has difficulty docking.	The boundary wire is not laid in a long straight line that is far enough out from the charging station.	Check that the charging station has been installed according to the instructions. Refer to To install the charging station
	The guide wire is not inserted in the slot under the charging station.	It is absolutely critical for operation that the guide wire is perfectly straight and is in the correct position under the charging station. Therefore make sure that the guide wire is always in its slot in the charging station. Refer to To install the guide wire.
	The charging station is on a slope.	Place the charging station on a surface that is entirely level. Refer to To examine where to put the charging station.
The product runs at the wrong time	The product clock needs to be set.	Set the clock. Refer to To set the time & date.
	The start and stop times for mowing are incorrect.	Reset the start time and stop time settings for mowing. Refer to To reset the timer setting.
The product vibrates.	Damaged blades lead to imbalance in the cutting system.	Inspect the blades and screws and replace them if necessary. Refer to To replace the blades.
	Too many blades in the same position lead to imbalance in the cutting system.	Check that only one blade is fitted at each screw.
	Different versions (thickness) of GARDENA blades are used.	Check if the blades are of different versions.
The product runs, but the blade disc does not rotate.	The product searches for the charging station.	No action. The blade disc does not rotate when the product is searching for the charging station.
The product mows for shorter periods than usual between charges.	Grass or other foreign object blocks the blade disc.	Remove and clean the blade disc. Refer to Clean the product
	The battery is spent.	Replace the battery. Refer to Battery .
Both the mowing and charging times are shorter than usual.	The battery is spent.	Replace the battery. Refer to Battery.
The product is parked for hours in the charging station.	The product has an inbuilt standby period according to the Standby time table. Refer to Timer and Standby.	No action.
	The hatch has been closed without the START button first being pressed.	Open the hatch, press the START button and then close the hatch.
Uneven mowing results.	The product works too few hours per day.	Increase the mowing time. Refer to To calculate the timer setting.
		SensorControl senses that the lawn have been mowed more than it actually has. Increase the intensity level in the SensorControl. If this does not help, turn off the Sensor control. Refer to SensorControl.
	The How often? setting is incorrect in relation to the layout of the work area.	Check that the correct How often? value is selected.
	The shape of the work area requires the use of Area 1-3 for the product to find its way to all remote areas.	Use Area 1-3 to steer the product to a remote area. Refer to Lawn Coverage.
	Work area too large.	Try limiting the work area or extending the work time. Refer to To do the timer settings.
	Dull blades.	Replace all the blades. Refer to To replace the blades.
	Long grass in relation to the set cutting height.	Increase the cutting height and then successively lower.
	Accumulation of grass by the blade disc or around the motor shaft.	Check that the blade disc rotates freely and easily. If not, screw off the blade disc and remove grass and foreign objects. Refer to Clean the product.

Find breaks in the loop wire

Breaks in the loop wire are usually the result of unintentional physical damage to the wire such as when gardening with a shovel. In countries with ground frost, also sharp stones that move in the ground can damage the wire. Breaks can also occur due to the wire being stretched excessively during installation.
Mowing the grass too low right after the installation can damage wire insulation. Damage to the insulation may not cause disruptions until several weeks or months later. To avoid this, always select the maximum cutting height the first weeks after installation and then lower the height one step at a time every second week until the desired cutting height has been reached.
A defective splicing of the loop wire can also lead to disruptions several weeks after the splice was done. A faulty splice can, for example, be the result of the original coupler not being pressed together hard enough with a pair of pliers, or that a coupler of lower quality than the original coupler has been used. Please first check all known splices before further troubleshooting is done.
A wire break can be located by gradually halving the distance of the loop where the break may have occurred until there is only a very short section of the wire left.
The following method does not work if ECO mode is activated. Make sure first that ECO mode is turned off. Refer to ECO mode.

1. Check that the indicator lamp in the charging station flashes blue, which indicates a break in the boundary loop. Refer to Indicator lamp in the charging station.
   
2. Check that the boundary wire connections to the charging station are properly connected and not damaged. Check that the indicator lamp in the charging station is still flashing blue.
   
3. Switch the connections between the guide wire and the boundary wire in the charging station.
   Start by switching connection AL and G1.
   If the indicator lamp is lit with a solid green light, then the break is somewhere on the boundary wire between AL and the point where the guide wire is connected to the boundary wire (thick black line in the illustration).
   

To rectify the fault you will need boundary wire, connector(s) and coupler(s):

1. If the suspected boundary wire is short then it is easiest to exchange all of the boundary wire between AL and the point where the guide wire is connected to the boundary wire (thick black line).
2. If the suspected boundary wire is long (thick black line) then do as follows: Put AL and G1 back to their original positions. Then disconnect AR. Connect a new loop wire to AR. Connect the other end of this new loop wire at the middle of the suspected wire section.
   

If the indicator lamp now is green, then the break is somewhere in the wire between the disconnected end to the point where the new wire is connected (thick black line below). In that case, move the connection for the new wire closer to the disconnected end (roughly at the middle of the suspected wire section) and check again if the indicator lamp is green.
Continue until only a very short section of the wire remains which is the difference between a solid green light and a flashing blue light. Then follow instruction in step 5 below.

4. If indicator lamp still flashes blue in step 3 above: Put AL and G1 back in their original positions. Then switch AR and G1. If indicator lamp now is lit with a solid green light then disconnect AL and connect a new boundary wire to AL. Connect the other end of this new wire at the middle of the suspected wire section. Follow the same approach as in 3a) and 3b) above.
5. When the break is found, the damaged section must be replaced with a new wire. Always use original couplers.
