Before starting the equipment

Art. No. 34.131.57 is supplied without a battery pack and without a charger.
The lawn mower is delivered partly assembled. The push bar and the grass basket must be assembled before using the lawn mower. Follow the instructions step by step and refer to the pictures when assembling.

Required assembly parts (screws, cable guides, etc.) or functional parts (e.g. plugs, wrenches, etc.) can be found in the molded parts of the packaging or on the equipment.

Always pull out the safety plug before making adjustments to the equipment.

Fitting the push bar (Fig. 3a to 3c)
Take a bottom push bar (Fig. 2 /Item 3) and fasten it with the nut (Fig. 2/Item 13) as shown in Fig. 3a. Proceed in the same way on the other side. Screw the top push bar (Fig. 2/Item 2) to the bottom push bar (Fig. 2/Item 3) as shown in Fig. 3b.
Then attach the power cable to the push bar (Fig. 2/Item 14) using the cable clips (Fig. 3c).
Make sure that the cable and cable clips do not obstruct the push bar when it is flipped over.

Mounting the grass basket (Fig. 4a to 4c)
Plug the bottom and the top part of the grass box together (Fig. 4a/Item 9, 10). Ensure that all the plastic lugs engage correctly. Next push the grass box handle (Fig. 4b/Item 11) into the openings on the grass box. Check that the handle is secure and correctly positioned. Before you fi t the grass basket you must ensure that the motor is switched off and the blade is not rotating. The grass box must be attached to the two hooks on the mower. To do this, open the ejector flap with one hand (Fig. 4c/Item 7) and attach the grass box with the other hand. The ejector flap is held against the grass box by a spring.

Adjusting the cutting height

Adjust the cutting height only when the motor has been switched off and the safety plug has been disconnected.
Before you begin to mow, check to ensure that the blade is not blunt and that none of the fasteners are damaged. To prevent any imbalance, replace blunt and/or damaged blades. To carry out this check, first switch off the motor and pull out the safety plug.
The cutting height is adjusted as shown in Figure 5. To do so, turn the equipment upside down or tilt it to the side. Position both the front and rear axle in the same notch, so that the cutting blade runs parallel to the lawn.

Position Cutting depth

1. 70mm
2. 50mm
3. 30mm

Charging the battery (Fig. 6)

1. Take the battery pack out of the equipment.
   Do this by pressing the side pushlock buttons.
2. Check that your mains voltage is the same as that marked on the rating plate of the battery charger. Insert the power plug of the charger (17) into the socket outlet. The green LED will then begin to flash.
3. Insert the battery pack (16) into the battery charger (17).
4. In the section entitled „Charger indicator" you will fi nd a table with an explanation of the LED indicator on the charger.

The battery pack can become a little warm during the charging. This is normal. If the battery pack fails to charge, check:

• whether there is voltage at the socket outlet
• whether there is good contact at the charging contacts

If the battery pack still fails to charge, send

• the charging unit
• and the battery pack to our customer service center.

To ensure that items are properly packaged and delivered when you send them to us, please contact our customer service or the point of sale at which the equipment was purchased.
When shipping or disposing of batteries and cordless tools, always ensure that they are packed individually in plastic bags to prevent short circuits and fi res.
To ensure that the battery pack provides long service, you should take care to recharge it promptly. You must recharge the battery pack when you notice that the performance of the device drops. Never allow the battery pack to become fully discharged. This will cause it to develop a defect.

The battery has an adequate remaining charge.

1 LED flashes:
The battery is empty, recharge the battery.

All LEDs blink:
The battery temperature is too low. Remove the battery from the equipment, keep it at room temperature for one day. If the fault reoccurs, this means that the rechargeable battery has undergone exhaustive discharge and is defective. Remove the battery from the equipment. Never use or charge a defective battery.

Installing the battery (Fig. 8/9)

• Open the battery cover.
• Insert the battery pack in the mount.
• Close the battery cover by flipping the cover down

Operation

The lawn mover is equipped with a safety circuit to prevent unauthorized use. Directly before starting up the lawn mover insert the safety plug (Fig. 9/Item 15) and remove the safety plug again whenever you interrupt or terminate your work.

To prevent the equipment switching on accidentally, the lawn mower is equipped with a safety switch (Fig. 10/Item 8) which must be pressed before the switching bar (Fig. 10/Item 1) can be activated. The lawn mower switches itself off when the switching bar is released. The start time can amount to several seconds. Repeat this process several times so that you are sure that the machine functions properly. Before you perform any repair or maintenance work on the equipment, ensure that the blade is not rotating and that the safety plug is disconnected.

Never open the chute flap when the grass bag has been detached (to be emptied) and the motor is still running. A rotating blade can cause serious injuries!
Always carefully fasten the chute flap and grass basket. Switch off the engine before emptying the grass basket.
Always ensure that a safe distance (provided by the length of the long handles) is maintained between the user and the mower housing. Be especially careful when mowing and changing direction on slopes and inclines. Maintain a solid footing and wear sturdy, non-slip footwear and long trousers.
Always mow along the incline (not up and down). For safety reasons, the lawn mower may not be used to mow inclines whose gradient exceeds 15 degrees.
Use special caution when backing up and pulling the lawn mower. Tripping hazard!

Tips for proper mowing
It is recommended that you overlap the mowing swaths.
Only use a sharp blade that is in good condition. This will prevent the grass blades from fraying and the lawn from turning yellow.
Try to mow in straight lines for a nice, clean look. The swaths should overlap each other by a few centimeters in order to avoid stripes.
The operating time of the rechargeable batteries and therefore the area in square meters that can be covered with a single battery charge is largely dependent on the state of the grass (e.g. density, moisture, height, cutting height, etc.) and the mowing speed (walking speed). To adjust the area coverage to your individual requirements, it is recommended that you mow the lawn more often, with a higher cutting height and at an appropriate speed. Frequently turning the equipment on and off while mowing will also reduce the amount of area that you can cover. If the operating time of the rechargeable batteries (area coverage) is still unsatisfactory in spite of the above measures, you can remedy the problem by using rechargeable batteries with a larger capacity (Ah).
How frequently you should mow your lawn is determined primarily by the speed at which the grass grows. In the main growing season (May - June) you will probably need to mow the lawn twice a week, otherwise just once a week. The cutting height should be between 4 - 6cm and the amount of growth before mowing again should be 4 - 5cm. If the grass is allowed to grow somewhat longer for whatever reason, do not make the mistake of cutting it back to the normal height in one go. This will harm the lawn. Never cut it back by more than half the height in one go.
Keep the underside of the mower housing clean and remove grass build-up. Deposits not only make it more difficult to start the mower; they decrease the quality of the cut and make it harder for the equipment to bag the grass.
Always mow along inclines (not up and down). You can prevent the lawn mower from slipping down by holding a position at an angle upwards.
Select the cutting height according to the length of the grass. Make several passes so that no more than 4cm of grass are cut at one time. Switch off the motor before doing any checks on the blade. Keep in mind that the blade continues to rotate for a few seconds after the motor has been switched off. Never attempt to manually stop the blade. Regularly check to see if the blade is securely attached, is in good condition and is sharp. If the contrary is the case, sharpen the blade or replace it. In the event that the blade strikes an object, immediately switch off the lawn mower and wait for the blade to come to a complete stop. Then inspect the condition of the blade and the blade mount. Replace any parts that are damaged.
As soon as grass clippings start to trail the lawn mower, it is time to empty the grass basket.

Before taking off the grass basket, switch off the motor and wait until the blade has come to a stop.
To take off the grass basket, use one hand to lift up the chute flap and the other to grab onto the basket handle. Remove the basket. For safety reasons, the chute flap automatically falls down after removing the grass basket and closes off the rear chute opening. If any grass remains in the opening, it will be easier to restart the engine if you pull the mower back approximately 1m.
Do not use your hands or feet to remove clippings in or on the mower housing, but instead use suitable tools such as a brush or a hand broom.
In order to ensure that the majority of grass clippings are picked up, the inside of the grass basket must be cleaned after each use.
Reattach the grass basket only when the motor is switched off and the blade has stopped.
Lift up the chute flap with one hand and, holding the grass basket by its handle with the other hand, hang in the basket from the top.

Cleaning, maintenance and ordering of spare parts

Pull the safety plug before carrying out any cleaning work (Fig. 9).

Cleaning

• Keep all safety devices, air vents and the motor housing free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it with compressed air at low pressure.
• Do not clean the lawn mower with running water, particularly with high-pressure water.
• We recommend that you clean the device immediately each time you have finished using it.
• Clean the equipment regularly with a moist cloth and some soft soap. Do not use cleaning agents or solvents; these could attack the plastic parts of the equipment. Ensure that no water can seep into the device.
• For best results, clean the lawn mower with a brush or rag.

Maintenance

• Worn out or damaged blades, blade mounts, and bolts should be replaced as a set by an authorized professional in order to keep the equipment in balance.
• Ensure that all mounting components (i.e. screws, bolts, nuts etc.) are always tightened so that the equipment can be safely operated at all times.
• Frequently check the grass catch assembly for signs of wear.
• Replace excessively worn or damaged parts immediately.

• In order to ensure that you enjoy the equipment for many years to come, all screwed parts, as well as the wheels and axles, should be cleaned and lubricated.
• Keeping your lawn mower in good condition not only ensures a long lifespan and high performance, but also enables the equipment to thoroughly cut your grass with minimal effort.
• The blade is subjected to more wear and tear than any other component. Therefore, routinely check the condition of the blade and make sure that it is tightly fastened. If the blade is completely worn out, it must be immediately replaced or ground sharp again. An excessively vibrating mower means that the blade is not properly balanced or has become deformed from striking an object. In this case, the blade must be repaired or replaced.
• There are no parts inside the equipment which require additional maintenance.

Replacing the blade

Remove the rechargeable battery/batteries. For safety reasons, we recommend having the blade replaced by an authorized professional. Important! Wear work gloves! Only replace the blade with a genuine Einhell replacement blade, as this will ensure top performance and safety under all conditions.
Carry out the following steps to change the blade:

1. Undo the fastening screw (see Fig. 11).
   
2. Remove the blade and replace with a new one.
3. When fitting the blade, make sure it is installed in the right direction. The blade's air vanes must project into the motor compartment (see Fig. 11). The dome mounts provided on the equipment must be aligned with the punch holes provided in the blade (see Fig. 12).
   
4. Then retighten the fastening screw with a wrench. The tightening torque should be approx. 25 Nm.

At the end of the season, perform a general inspection of the lawn mower and remove any grass and dirt which may have accumulated. At the start of each season, ensure that you check the condition of the blade. If repairs are necessary, please contact our customer service center. Use only genuine spare parts.
