Original operating instructions
Safety instructions

Proper use

The equipment can be used both as ascariﬁer and an aerator depending on the intended use. Only a few movements are required to change the roller.
The scarifying 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).
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.
Scariﬁers 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.
Important! 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 mole hills.
For safety reasons, the scariﬁer may not be used as a drive unit for other equipment or toolkits of any kind, unless speciﬁcally advised to do 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 de-signed 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.

Now join the tubes together using the screws (Fig. 8/Item 18), washers (Fig. 8/Item 17) and quick-release levers (Fig. 8/Item 13) supplied.
Use the cable clips (Fig. 9/Item 12) to attach the power cable to the tubes of the push bars so that it is possible to open and shut the ejector flap (Fig. 10/Item 12).

Important!
Please ensure that the ejector ﬂ ap can be opened and closed easily!
Assembling the grass basket (see Figs. 11-14)

Push both frame parts into each other (Fig. 11).
Pull the grass basket over the metal frame (Fig. 12).
Pull the rubber clips over the metal frame (Fig. 13).
To hang the grass basket on the scarifier you must lift the ejector flap (Fig. 14/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 (Fig. 14).

Important!
Before you ever hook the grass basket to the scariﬁ er you must ensure that the motor is switched
oﬀ and the cutting unit is not rotating.
Adjusting the handlebar height (see Fig. 15) Undo the quick-release levers (Fig. 15/Item 13) on both sides of the scariﬁer.
Important. The height of the handlebar can be set to position 1 or 2 (Fig. 15) during operation. You must then tighten the quick-release fasteners again.
Important. The same tilt angle must be set on both sides.
Adjusting the scariﬁer depth (see Fig. 16) The scariﬁer depth is set with the adjustment mechanism. Pull the lever in the direction indicated by the arrow (see Fig. 16) and adjust to the required position (0/ 1/ 2/ 3). Make sure that the lever latches in place correctly!

0 = drive/transport position
1 = scariﬁer depth 3 mm
2 = scariﬁer depth 6 mm
3 = scariﬁer depth 9 mm
4 = scariﬁer depth 12 mm

Electrical connection
The equipment can be connected to any normal socket with 230V AC. It is only acceptable to connect it to a shockproof socket with a 16A circuit breaker. Furthermore, a residual-current-operated protective device with max. 30 mA should be connected upstream.
Power cable
Please only use power cables that are not damaged. The total length of the power cable should not exceed 50 meters; going beyond this distance will reduce the power output of the electric motor. The power cable must have a cross-section of 3 x 1.5 mm2. The insulating sheath of scariﬁer power cables is frequently damaged.
Some of the causes for this are:

Cracking from running over the cable
Pinching when the power cable is dragging under doors and pulled through windows
Cracking due to old age of the insulation
Kinking by improperly fastening or guiding the power cable

The power cables must, at the very minimum, be of type HO5RN-F and 3-stranded. The cable type must be printed somewhere on the power cable. Only purchase power cables that are marked as such! Plugs and socket couplers for the power cables must be made from rubber and be splash-proof. There is a limit to how long power cables can be. Longer power cables require larger con-ductor cross- sections. Power cables and connec-ting lines must be regularly checked for damage. Ensure that the lines are de-energized before checking them. Completely unwind the power cable. Also check power cable entry points, plugs and socket couplers for kinks.

Operation

Connect the machine’s power supply cable to the plug (Fig. 17/Item A) and secure the power cable with the stress-relief clip (Fig 17/Item 4).
Important! To prevent accidental start-up of the equipment, the push-bar (Fig. 18 / Item 5) is equipped with a safety lock-oﬀ (Fig. 18 / Item 2) which must be pressed before the lever switch (Fig. 18 / Item 1) can be pressed. If the lever switch is released, the equipment switches oﬀ . 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 machine, ensure that the cutting unit is not rotating and that the power supply is disconnected.
Important!
Never open the ejector ﬂ ap when the motor is running. A rotating cutting unit can cause injuries. Always fasten the ejector ﬂap carefully. The ﬂap 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 scariﬁer may not be used to scarify inclines whose gradient exceeds 15 degrees.
Use special caution when backing up and pulling the scariﬁer (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. Ins doing, the aeration swaths should always overlap each other by a few centimeters in order to avoid bare strips. As soon as grass clippings start to trail the scariﬁer, it is time to empty the grass basket.
Important! 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 ﬂap 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 di ﬃ cult 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.
Important!
The roller rotates 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 8.4). Lay the power cable on the ground in loops in front of the power outlet. Scarify away from the power outlet and cable, making sure that the power cable always trails in the already scariﬁed grass so that the equipment does not travel over the cable.

Replacing the power cable

If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel to avoid danger.

Cleaning, maintenance and ordering of spare parts

Always pull out the mains power plug before star-ting any cleaning work.

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 at-tack 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.
The cooling air supply is equipped with an air filter to prevent soiling of the motor compartment. Clean the air filter each time after using it. The cover (Fig. 24/Item A) can be swung forward and unhooked by pressing on the lug (Fig. 24/Item B). Clean the air filter by tapping it. When inserting, make sure that the two nibs (Fig. 25/Item C) hook into the corresponding recesses in the housing. The cover can then be swung up and closed. Make sure that the cover closes correctly; if not, filtering cannot be guaranteed.

Carbon brushes

In case of excessive sparking, have the carbon brushes checked only by a qualiﬁed electrician. Important! The carbon brushes should not be rep laced by anyone but a qualiﬁed electrician.

Maintenance

A worn out or damaged cutting unit should be replaced by an authorised expert (see adress on the warranty certificate).
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 simple 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 (see address on the warranty certificate) if repair work is necessary.

The push bar has a P position (Fig. 15) in order to take up less space during storage. To adopt this position you must loosen the quick-release levers by approx. 3 turns to allow for the higher fastening in the parking position. With the bar in this position, the scariﬁ er can be stood in a corner in minimum space (Fig. 19). When you return the bar to the working position, remember to tighten the quick-release levers again by 3 turns!

Changing the roller (see Figures 20-23)

Important. Be sure to wear work gloves!
Only replace the roller with a genuine Einhell roller, as this will ensure top performance and safety under all conditions.
Remove the two Allen screws (Fig. 20 / Item A). Lift the roller on this side and pull out in the direction of the arrow (Fig. 21).
Now slide the new roller in the direction of the arrow (Fig. 23) onto the square-ended drive (Fig. 22 / Item A) and press into the holder (Fig. 23). Refasten the roller with the two Allen screws (Fig. 20 / Item A).
Apply grease to the square-ended drive from time to time so that the rollers can be changed easily.
Important. If the blade roller is set unfavorably, the outer blade (Fig. 21/Item A) may be blocked by the housing. In this case move the roller half a turn
