Proper use

The basic version of the equipment is a scarifi er intended for private use, i.e. for use in home and gardening environments. The scarifi er roller is designed for ripping moss and weeds – complete with their roots – out of the soil and for loosening the soil. As a result your lawn can absorb nutrients better and is cleaned. We recommend you to scarify your lawn in the spring (April) and autumn (October).
With the additional aerator roller (Art. No. 34.059.41), available as an option, the equipment can be converted to a lawn aerator in just a few steps.

The aerating roller scratches the surface of the lawn, helping water to drain off more easily as well as promoting oxygen intake. Aerate your lawn throughout the growing period.
The equipment is intended for private use i.e. for use in home and gardening environments.
Scarifi ers for private use are machines whose annual operating time generally does not exceed 10 hours, during which the machine is primarily used to maintain small-scale, residential lawns and home/hobby gardens. Public facilities, sporting halls, and agricultural/forestry applications are excluded.
The operating instructions as supplied by the manufacturer must be kept and referred to in order to ensure that the equipment is properly used and maintained. The instructions contain valuable information on operating, maintenance and servicing conditions.

Warning! Due to the high risk of bodily injury to the user, the equipment may not be used to grind up branch or hedge clippings. Moreover, the equipment may not be used as a power cultivator to level out high areas such as molehills.

For safety reasons, the scarifi er may not be used as a drive unit for other equipment or toolkits of any kind, unless specifi cally advised doing so by the manufacturer.
The equipment is to be used only for its prescribed purpose. Any other use is deemed to be a case of misuse. The user/operator and not the manufacturer will be liable for any damage or injuries of any kind caused as a result of this.
Please note that our equipment has not been designed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.

Before starting the equipment

Warning!
Always pull out the safety plug before performing any adjusting, repair, maintenance or cleaning work on the equipment.
The scarifi er is delivered unassembled. The com-plete push bar must be assembled and mounted before using the scarifi er.
Follow the operating instructions step-by-step and use the pictures provided as a visual guide to easily assemble the machine.
Important! Required assembly parts (screws, cable guides, etc.) or functional parts (e.g. plugs, wrenches, etc.) can be found in the shaped parts of the packaging or on the equipment.
Fitting the push bar holders and cable clips (Fig. 3 – 6)

1. Screw the left push bar holder (Item 5) securely on the housing. Make sure that the em-bossing (Fig. 2 / Item A) faces inwards. Then screw on the right-hand push bar holder (Fig. 2 / Item 12) securely.
2. Use the fastening screws (Item 14) and the wing nuts (Item 13) to screw one tube (Item 4) securely on each push bar holder (Item 5 / 12).
3. Screw the upper push bar (Item 3) on each tube (Item 4). Use the push bar fastening screws (Item 14) and the wing nuts (Item 13) similarly for this purpose.
4. Fasten the power cable to the push bar tubes using the supplied cable clips (Item 11). Make sure that the cable and cable clips do not obstruct the push bar when it is flipped over (see section 8).

Important! There are 2 assembly holes so that the height of the push bar can be adjusted to spe-cifi c user requirements at any time. Use the hole which is best suited for you, making sure that you use the same hole on both sides.
Please ensure that the ejector fl ap can be opened and closed easily!

Fitting the optional catch basket(see Fig. 7-8)
The basic version of the equipment does not in-clude a catch basket. This is available separately (Art. No. 34.059.40).

To hang the grass basket on the scarifier you must lift the ejector flap (Item 10) with one hand and with the other hand take hold of the grass bag by the handle and hook it onto the scarifier from above.

Danger!
Before you ever hook the grass basket to the sca-rifi er you must ensure that the motor is switched off and the cutting unit is not rotating.
Adjusting the working depth (see Fig. 9) The scarifi er depth is adjusted at the two front wheels using the adjustment mechanism. For this, pull out the adjusting screw and turn the wheel to the left or right into one of the available positions (0/I/II/III).

The scarifi er depth must always be identically set on both sides!

0 = drive/transport position
I = scarifi er depth 2 mm
II = scarifi er depth 4 mm
III = scarifi er depth 6 mm

Charging the battery (Fig. 10)
The equipment is supplied without batteries and without a charger!

1. Take the battery pack out of the equipment. Do this by pressing the pushlock buttons (Fig. 11/Item C).

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
   (22) into the socket outlet. The green LED will then begin to fl ash.

3. Insert the battery pack (21) into the battery charger (22).

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.

Battery capacity indicator (Fig. 11)
Press the switch for the battery capacity indicator (Item A). The battery capacity indicator (Item B) shows the charge status of the battery using 3 LEDs.

All 3 LEDs are lit:
The battery is fully charged.

2 or 1 LED(s) are lit:
The battery has an adequate remaining charge.

1 LED fl ashes:
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 tem-perature for one day. If the fault reoccurs, this me-ans that the rechargeable battery has undergone exhaustive discharge and is defective. Remove the battery from the equipment. Never use or charge a defective battery.

Fitting the battery (Fig. 12 – 13)
Note: The battery cover is self-closing and is held shut by 2 magnets. If the safety plug (Item 15) is already installed, remove it before fi tting the battery.

• Open the battery cover (Item 6) and hold it open. Push the battery (Item 21) into the mount until you hear the battery engage.

Operation

Caution!
The scarifi er is equipped with a safety switch to prevent unauthorized use. Directly before starting up the scarifi er insert the safety plug (Fig. 13/Item 15) and remove the safety plug again when interrupting or terminating your work.
To prevent accidental start-up of the scarifi er, the push bar (Fig. 14/Item 3) is equipped with a safety lock-off (Fig. 14/Item 2) which must be pressed before the lever switch (Fig. 14/Item 1) can be pressed. The start time for the equipment can amount to several seconds. If the lever switch is released, the scarifi er switches off. Repeat this process several times so that you are sure that your equipment functions properly. Always pull out the safety plug before performing any adjusting, repair, maintenance or cleaning work on the equipment. Make sure that the spike drum is not rotating.

Danger! Never open the ejector fl ap when the motor is running. A rotating cutting unit can cause injuries. Always fasten the ejector fl ap carefully.

The fl ap flips back to the “Closed” position by the tension springs! Always ensure that a safe distance (provided by the long handles) is maintained between the user and the housing. Be especially careful when scarifying and changing direction on slopes and inclines. Maintain a solid footing and wear sturdy, non-slip footwear and long trousers. Always scarify along the incline (not up and down). For safety reasons, the scarifi er may not be used to scarify inclines whose gradient exceeds 15 degrees.
Use special caution when backing up and pulling the scarifi er (tripping hazard)!

Tips for proper working
It is recommended that you overlap scarifying paths a little.
Try to scarify in straight lines for a nice, clean look. In so doing, the aeration swaths should always overlap each other by a few centimeters in order to avoid bare strips.
If you use the catch bag which is available as an option, it has to be emptied as soon as grass clippings start to trail behind during scarifying.
Danger! Before taking off the grass basket, switch off the motor and wait until the roller has come to a stop.
To remove the grass basket, lift up the ejector fl ap with one hand, while unhooking the basket with the other.
How frequently you should scarify your lawn is determined primarily by the speed at which the grass grows and the hardness of the soil.
Keep the underside of the equipment clean and remove soil and grass build-up. Deposits make it more difficult to start the aerator and decrease the quality of the scarifying.
Always scarify along inclines (not up and down). Switch off the motor before doing any checks on the roller.

Danger!
The cutting unit is equipped with moving blades and will rotate for a few seconds after the motor is switched off.
Never attempt to stop the roller. In the event that the rotating roller strikes an object, immediately switch off the equipment and wait for the roller to come to a complete stop. Then inspect the condition of the roller. Replace any parts that are damaged (see section 7.3).
Tips on aerating properly with the aerator roller available as an option.
The way of working for aerating is the same as for scarifying.
You should therefore observe these safety instructions and notes on working practice.

Cleaning, maintenance and ordering of spare parts

Danger!
Always pull out the safety plug before performing any adjusting, repair, maintenance or cleaning work on the equipment. Make sure that the spike drum is not rotating.

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.
• 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. The ingress of water into an electric tool increases the risk of an electric shock.

Maintenance

• A worn out or damaged cutting unit should be replaced by an authorised expert.
• Take care that all fastening elements (screws, nuts, etc.) are firmly tightened, so that you can work safely with the scarifier.
• Store the scarifier in a dry place.
• For longer life, all screw-fastened parts, such as wheels and axles should be cleaned and subsequently oiled.
• Regular servicing of the scarifier not only secures longer endurance and performance, but also contributes to an accurate and simp-le scarification of your lawn.
• At the end of the season, carry out a general check of the scarifier, and remove all residue collected. Before the start of every season, it is absolutely necessary to check the state of the scarifier. Contact our Customer Service if repair work is necessary.

Changing the roller (see Figures 15-19)
Be sure to wear work gloves!
Only replace the roller with a genuine Einhell rol-ler, as this will ensure top performance and safety under all conditions.
To change the scarifi er roller or the optionally available aerator roller (Fig. 17, Art. No.: 34.059.41), proceed as follows:
Remove the two socket head screws (Fig. 15 / Item D). Lift the roller at this end (Fig. 16) and pull it out in the direction of the arrow. If the holder (Fig. 17 / Item E) does not exist on the roller you want to install, remove it from the previously used roller and fi t it on the roller you now want to use. Slide the new roller in the direction of the arrow (Fig. 19) onto the square- ended drive (Fig. 18 / Item F) and then press it into the holder (Fig. 19). Use the two socket head screws (Fig. 15 / Item D) to secure the roller again.
Apply grease to the square-ended drive from time to time so that the rollers can be changed easily.
