17 PRESENTATION Starter handle Misuse of the starter handle can damage the starter. Never twist the starter cord around your hand. Pull out the handle slowly until the gears mesh. Do not pull out the starter cord completely and do not let go of the starter handle when extended.
18 OFF OFF ON ON PRESENTATION Spark plug The engine spark plug is hidden under the ignition cable shoe. When performing service, it is important that the engine cannot start accidentally. For this reason, always remove the ignition cable shoe from the spark plug.
19 PRESENTATION Fuel tank Underneath the tank, there is a fuel filter combined with the fuel valve. The tank can be filled with 3.6 liters/0.95 US Gal for the DT22. Fueling Read the safety instructions before fueling. Keep the fuel and fuel tank clean.
20 PRESENTATION Cutting unit Depth lever Use the depth lever to raise and lower the blades between working and transport position. When the lever is up, the blades are in working position. Blades should penetrate the soil to a depth of 1/8" to 1/4" with a maximum penetration of 1/2".
21 PRESENTATION Blade versatility Flail blade Thatch is the dense layer of clippings, roots and stems that forms between the soil and the base of the grass. As thatch builds up, it prevents water, air and fertilizer from being absorbed into the soil. This causes shallow root development leading to vulnerability to drought and frost.
22 OPERATION Starting the engine Check that all daily maintenance as described in the maintenance schedule has been performed. Check that there is sufficient fuel in the tank. Fuel valve Open the fuel valve. Turn the lever all the way to the right. Choke When starting the engine warm, the lever should be in the right position; see the illustration.
23 OFF OFF ON ON OPERATION Starter handle Misuse of the starter handle can damage the starter. Do not twist the starter cord around your hand. Pull out the handle slowly until the gears mesh. Then give a sharp pull on the starter handle. Do not pull out the starter cord completely and do not let go of the starter handle when extended.
24 IMPORTANT INFORMATION Clear the lawn of any debris. Clearly mark rocks and other fixed objects. Be especially sure to check for hidden electrical cables or similar in the surface of the lawn. OPERATION Before you start • Mow the lawn 1/2" shorter than normal.
25 Check the engine oil level 34 Replace engine oil 1) 34 Check the air filter 25 Clean the air filter 2) 25 Replace air filter cartridge 2) 25 Clean sludge reservoir for fuel system 26 Check and clea.
26 Replacing the air filter If the engine seems weak, produces black smoke or runs unevenly, the air filter may be clogged. For this reason, it is important to clean and replace the air filter regularly (see the maintenance schedule for the proper service interval).
27 Cleaning the sludge reservoir 1. Close the fuel valve. Idle adjustment 1. Start the engine and run it until it reaches normal working temperature. 2. Adjust the throttle to idle position or so that the engine runs at the lowest possible speed. 3. Turn the idle screw (1) so that the engine idles at 1250 – 1600 RPM.
28 Ignition system The engine is equipped with an electronic ignition system. Only the spark plug requires maintenance. For recommended spark plug, see chapter ” Technical data ” . MAINTENANCE IMPORTANT INFORMATION Fitting the wrong spark plug type can damage the engine.
29 MAINTENANCE Cutting unit Checking the drive belt 1. Allow the engine to cool. 2. Remove the spark plug cable. 3. Remove the belt guard (see illustration) on the left side of the machine. 4. Check that the belt is running in the proper track; the pulleys should guide the belt in a straight line.
30 MAINTENANCE Wear/Rotation/Replacing flail blades After you have used your dethatcher for some time, the blades will begin to wear on the striking edge. When this happens, their dethatching performance will diminish. A new combing edge may be obtained by rotating the entire rotor shaft assembly laterally (end to end).
31 MAINTENANCE Replacing worn flail blades 1. Allow the engine to cool. 2. Disconnect the spark plug. 3. Tip the machine forward; see the section ” Two minute rule ” . 4. Remove and dispose of the spring clips (1) (locking washer type) that hold the blade shaft (2) in place (see the illustration).
32 Wear/Replacing spring tines Over time and due to wear, the tines will diminish in length. When the tines can no longer be adjusted to comb 6 mm (1/4") into the soil, the tines must be replaced. Spring tines can be replaced without removing MAINTENANCE Wear/Replacing delta blades Over time and due to wear, the blades will diminish in length.
33 MAINTENANCE Two minute rule The machine may be tipped forward to facilitate access for cleaning or service, but no longer than 2 minutes . If the machine is held in this position for too long, the engine can be damaged by gasoline draining into the crankcase.
34 LUBRICATION Lubrication schedule General Stop the engine and remove the ignition cable before attempting to lubricate the machine. Unless otherwise specified, when lubricating with grease use Husqvarna ’ s Universal Grease no. 5310038-01 or Husqvarna ’ s Lubrication Grease UL 21 no.
35 LUBRICATION 1. Engine oil The engine should be warm (but not hot) when changing the oil. Warm oil flows out faster and leaves a smaller quantity of old oil inside the engine. 1. Place a suitable vessel underneath the oil drainage screw. Remove the oil dipstick (1) and the oil drainage screw (4).
36 LUBRICATION 3. Blades Cover the blades with a thin coat of oil to avoid rust. This is particularly important prior to winter storage or if the machine will not be used for a period of longer than 30 days. 4. Depth lever It is important to lubricate all links and joints so that they do not bind.
37 TROUBLESHOOTING Symptom Cause Action The engine will not start • User error Fuel valve closed. Open the fuel valve. Choke valve open. Close the choke with cold engine. Engine switch in OFF position. Turn the engine switch to ON. • Fuel system Fuel tank empty.
38 STORAGE To ready the machine for storage, follow these steps: 1. Clean the machine carefully, particularly the chassis and working equipment. Mend damage to the paint to prevent rust. 2. Inspect the machine for worn or damaged parts and tighten any nuts or bolts that may have become loose.
