2. To check the oil level, wipe the dipstick on a clean cloth and replace it in the tank until it stops.
3. After pulling it out, read off the oil level on the dipstick. The oil level should be in the marked area between the minimum and maximum marks.
4. Wipe off any spilt oil and close the oil filler cap (14).

Check the oil level every time before mowing and add oil when the lower marking point is reached.

Filling with Petrol

- Keep petrol in containers intended for this purpose;

• Only refuel outdoors and never with the engine running or when the machine is hot;
• Open the filler cap carefully to allow excess pressure to escape;
• Do not smoke whilst refuelling;
• Avoid skin contact and inhalation of the fumes;
• Remove spilt petrol;
• Keep petrol away from sparks, open flames and other ignition sources;

Do not use petrol/oil mixtures; e normal or super unleaded petrol;

• Only use clean, fresh petrol;

• Do not store petrol for longer than one month, as its quality deteriorates

• Unscrew the filler cap (15) and pour in the petrol to the lower edge of the filler.

Do not fill the tank entirely, to allow the petrol room to expand.

1. Wipe away petrol residues around the filler cap and close the filler cap.

Operation

Please observe local regulations concerning noise protection.

Setting the working positions

The implement has 2 principal position settings:. These can be adjusted using the lever (18).

graph TD
    A["Gear Icon"] --> B["Up Arrow"]
    B --> C["Gear Icon"]
    C --> D["Down Arrow"]

Transport position

This position sets the maximum safety spacing between the tool and the floor.

Working position

Set this position when working the implement.

When the implement is delivered it is in the Transport Position setting

Readjustment positions

The working position can be lowered with increased knife and sprung tine wear. Wear can be identified from an increasingly poor result.

Check that the appliance is turned off before adjusting the working position.

Pull up the adjusting knob (12). Turn the knob as appropriate and push it down to snap in. Use your other hand to hold the appliance.

The setting button is not intended for height adjustment but rather to compensate for wear. Selection of a readjustment position without the corresponding wear can overload the motor and damage the cylinder.

Starting and Stopping the Engine

Before switching on the implement ensure that it is not in contact with any objects. Keep your feet and hands well away from the cylinder and the ejector opening. Danger of injury!

Warning! Petrol is flammable. Start the engine at least 3 m away from the filling location.

Regularly check petrol and oil level (see „Initial Operation“) and refill in due time.

1. Set the On/Off switch (24) on the switching element to "On".

2. For a cold start set the choke lever(25) into position „START“.

For a warm start leave the choke lever (25) in position „RUN“.

1. Move the safety catch (2) towards the handle bar (1) and hold it.

2. Pull the starter cord (17).

3. When the engine starts, allow the starter handle to slowly slide back into the starter cable guide (16).

Stopping the engine:

6 Release the safety loop (2). The motor switches off and the knife is braked.

WARNING! The cylinder continues to run for a brief period after the implement has been switched off. Do not tilt or carry the implement while the motor is still running and do not touch the cylinder while it is still rotating. Danger of injury!

Working with the implement

To maintain a well cared-for lawn it should be aerated every 4 to 6 weeks.

Verticuting is a more intensive intervention than aerating and should only be carried out once a year, the best time being in spring after the lawn has been mown for the first time.

When working on slopes always proceed across the slope. Be particularly careful when walking backwards and pulling the implement. Danger of stumbling!

The shorter the grass, the better the lawn can be treated. Furthermore, the implement is less stressed and the service life of the cylinder is prolonged.

• The implement can be operated with or without the collection bag.
  Recommendation: Work with the collection bag for aerating and without the collection bag for verticuting.
• To ensure that the collision guard flap closes properly, remove any earth that may have collected on the collision guard springs and/or the housing. When working without the bag, check that the collision guard flap is tightly closed.
• Mow the lawn to the required grass height.
• Do not use the scarifier in long grass. It may otherwise wind around the scarifier blade and result in damage to the equipment.
• Select the appropriate working or readjustment position (in the event of cylinder wear) so that the implement is not overloaded.

GB

• Guide the implement at a walking pace down lanes that are as straight as possible. To ensure uninterrupted aerating or verticuting the individual lanes should always overlap by a few centimetres. Dwelling too long at the same place while the implement is running can damage the grass sward.
• Adjust the transport position setting (see "Setting the Working Position") when transporting the implement.
• Lift the implement to transport it over steps and sensitive surfaces (e.g. tiles).
• Always clean the implement after each use (see “Cleaning, Maintenance, Storage”).
• After having treated lawns with dense moss growth, it is advisable to reseed the lawn so that it can regenerate itself quicker.

Exchanging the cylinder

Switch off the engine, take out the spark plug connector and ensure that all moving parts are still:

Wear gloves when handling the cylinder.

1. Turn the implement over.

2. Loosen the fixing screws (22) with a 5mm Allen key.

3. Hold the roller (19) firmly with one hand and pull the bracket (23) to the right.
4. Tilt the cylinder (19) upwards and pull the shaft (21) out of its seat. Insert the new cylinder by reversing the sequence.

Cleaning and Maintenance

Have any repair and maintenance work not described in these instructions carried out by a specialist workshop. Use only original Grizzly replacement parts. Risk of accidents!

Carry out maintenance and cleaning work strictly with the engine switched off and spark plug connectors removed. Risk of injury!

Allow the equipment to cool before any maintenance and cleaning work. Elements of the engine are hot. Risk of burning!

Wear gloves when handling the blade.

Cleaning and General Maintenance Work

Do not tilt the equipment sideways or forwards. Operating fluids could leak out and the engine could be damaged.

• When work has finished remove plant residues adhering to the wheels, inside the ventilation opening, the grass ejector opening and the cylinder. Doe not use hard or pointed objects for this purpose as they could damage the implement.
• To ensure that the collision guard flap closes properly, remove any earth that may have collected on the collision guard springs and/or the housing.
• Completely empty the collection bag.

• Always keep the implement clean. Do not use cleaning agents or solvents. Do not use water to clean the engine as it could contaminate the fuel system.

We cannot be held liable for damage caused by our implements if they were improperly repaired, if non-original parts have been used or if they were used not in keeping with their intended purpose.

Replacing the Air Filter

Do not operate the equipment without the air filter otherwise dust and dirt will get into the engine and result in damage to the machine

1. Release the air filter cover (27) and flip open the cover

2. Remove air filter (26).

3. Replace a defective air filter with a new filter (see "Spare Parts").
4. To install, place new air filter (26) into the air filter cover (27)
5. Close the air filter cover.

Change / adjust spark plug

A worn spark plug or a spark gap that is too large will result in a reduction of engine performance.

1. Disconnect the spark plug connector (29) from the spark plug (28) by simultaneously pulling and turning.

2. Unscrew spark plug (28) counter clockwise with spark plug socket.

3. Check the spark gap using a feeler gauge (available from specialist shops). The spark gap

must be at least 0.75 mm.

1. If necessary, adjust the gap by carefully bending the ground electrode on the spark plug.

2. Clean the spark plug with a wire brush.

3. Insert the cleaned and adjusted spark plug or replace a damaged spark plug with a new one

( Torch F6RTC or Champion RN9Y or NGK BPR 6ES) (recommended torque 20 Nm, determined with a torque wrench).

Changing the Engine Oil

Changing the Engine Oil Change the engine oil with the petrol tank empty and the engine warm.

Change the engine oil for the first time after around 5 operating hours then every 50 operating hours or annually. Dispose of the used oil in an ecofriendly manner (see "Disposal/Environmental protection").

1. Remove the spark plug connector (29) (see "Maintaining the Spark Plug").
2. Open the oil tank cover (14) and pump out the motor oil with an oil pump.
3. Refill with engine oil

Adjusting the Bowden Cable

If the Bowden cable becomes misplaced and has too much play, it can be adjusted.

1. Loosen the lock nuts (30 and 32) in front of and behind the bracket (31).
2. • Turn the adjusting nut (33) anticlockwise:

The Bowden cable shortens.

- Turn the adjusting nut (33) clockwise:

The Bowden cable lengthens.

Adjusting the Carburettor

The carburettor has been preset in the factory for optimum performance. If readjustments are required, have the adjustments made by a specialist workshop.

General Storage Instructions

Do not store the equipment with a full collection box. In hot weather, the grass begins to ferment when heat is generated. Risk of fire.

• Clean and service the equipment before storage.
• Allow the engine to cool before storing the equipment in enclosed areas.
• Use suitable and authorised containers for storing fuel.
• Keep the equipment in a dry place that is protected from dust and out of reach of children.
• For space-saving storage, the upper handle bar can be folded down (see small image C) Release the wing nuts and fold down the handle bar so the equipment takes up less space. The Bowden cables must not be squashed when doing this.
• Do not wrap the equipment in nylon bags as damp and mould could form

Storage During Longer Breaks from Operation

Non-observance of the storage instructions may cause starting problems or permanent damage as a result of fuel residues in the carburettor.

• Empty petrol tank in a well-ventilated place.
• Empty carburettor: For this purpose, start motor and leave it running until the motor stops. Let motor cool down.
• Change the oil (see “changing the engine oil”).
• Preserve the engine:

- Unscrew the spark plug (see "cleaning and maintenance" - Change/adjust spark plug;

- Pour a tablespoon of engine oil through the spark plug hole into the engine compartment;

- Pull the starter cord slowly several times with the safety catch pulled in order to distribute the oil inside the engine;

- Screw the spark plug tight.

- Dispose of used oil and petrol residues in an ecofriendly manner (see "disposal / environmental protection").

There is no need to drain the petrol tank if a fuel stabiliser is added to the petrol.

Disposal / Environmental Protection

- Return the tool, accessories and packaging to a recycling centre when you have finished with them.

• Carefully drain the petrol and oil tanks and take your equipment to a recycling centre. The plastic and metal parts that are used can be separated by type and thus recycled.
