Page 21: Cutting Unit
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. Depth knob The knob is used to adjust the cutting depth of the blades. -
Page 22: Blade Versatility
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. -

Page 27: Replacing The Air Filter
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). WARNING! Allow the exhaust system to cool before performing service. -
Page 28: Cleaning The Sludge Reservoir
Cleaning the sludge reservoir Close the fuel valve. Unscrew the sludge reservoir (2). Make sure not to misplace the o-ring (1). Clean the reservoir and the o-ring in e.g. white spirit and dry carefully. Put the o-ring in place in its track and replace the sludge reservoir. -
Page 29: Ignition System
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”. IMPORTANT INFORMATION Fitting the wrong spark plug type can damage the engine. Remove the ignition cable shoe and clean around the spark plug. -
Page 30: Cutting Unit
Cutting unit Checking the drive belt Allow the engine to cool. Remove the spark plug cable. Remove the belt guard (see illustration) on the left side of the machine. Check that the belt is running in the proper track; the pulleys should guide the belt in a straight line. - Page 31 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).
- Page 32 Replacing worn flail blades Allow the engine to cool. Disconnect the spark plug. Tip the machine forward; see the section ”Two minute rule”. IMPORTANT INFORMATION When tipping the machine forward observe the ”Two minute rule”. Remove and dispose of the spring clips (3) (locking washer type) that hold the blade shaft (2) in place (see the sketch).
- Page 33 Wear/Replacing delta blades Over time and due to wear, the blades will diminish in length. Once the blades have worn down by about 19 mm (3/4"), the overall length of the blade at the longest point of the blade will be about 64 mm (2 1/2"), and it will be necessary to replace the blades.
-
Page 34: Two Minute Rule
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. -
Page 35: Lubrication
LUBRICATION Lubrication schedule 8011-281 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. 5310060-74. Wipe away excessive grease after lubrication. -
Page 36: Engine Oil
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. Place a suitable vessel underneath the oil drainage screw. Remove the oil dipstick (1) and the oil drainage screw (4). -
Page 37: Oil Change Reduction Gear 1:6
2. Oil change reduction gear 1:6 The reduction gear only appears on a special version of model DT18C. The engine’s reduction axle does not have a drainage screw, but the oil can be drained through the level plug hole (2) by tipping the machine forward. -
Page 38: Depth Knob With Depth Lock
3. Depth knob with depth lock Lubricate the threads regularly with grease to avoid binding or locking. It is particularly important to lubricate the threads after cleaning. 4. 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. -
Page 39: Troubleshooting
Symptom Cause The engine will not start • User error Fuel valve closed. Choke valve open. Engine switch in OFF position. • Fuel system Fuel tank empty. Machine stored without observing proper procedure from chapter ”Storage/Winter storage” Contamination, water or ice in fuel system. -
Page 40: Storage
Winter storage At the end of the season, the machine should be readied for storage (or if it will not be in use for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function. -
