CONTROLS Engine Refer to your engine manual. Fueling Read the safety instructions before fueling. Keep the fuel and fuel tank clean. Avoid filling the machine with dirty fuel. Make sure the fuel cap is properly tightened and the gasket is not damaged, particularly before washing the machine. Use unleaded gasoline with minimum 86 octane rating. Never use gasoline mixed with two-cycle oil. For ethanol and methanol fuel, the following applies: 8011-019 Maximum allowable ethanol 10% (volume).
CONTROLS 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. Excessive thatch also creates an ideal environment for insects and lawn diseases. Powerraking with flail blades removes this thatch layer and restores your lawn to good health.
OPERATION Before you start • Mow the lawn ½" shorter than normal. • Allow the lawn to dry. Wet conditions can cause extensive damage to healthy grass. FLAIL BLADES OR SPRING TINES: • Flail Blades or Spring Tines: Set blade or tine depth so that the blades or tines just touch on a flat surface such as a sidewalk or driveway. Blades should never contact soil. IMPORTANT INFORMATION Clear the lawn of any debris. Clearly mark rocks and other fixed objects.
MAINTENANCE Maintenance schedule The following is a list of maintenance procedures that must be performed on the machine. For those points not described in this manual, visit an authorized service workshop.
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. 5. Check that the belt and pulleys are not oily. If they are, first try to clean them with spirits.
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). This procedure can be repeated until the blades reach their wear limit; see illustration. PR22>3.
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”. IMPORTANT INFORMATION When tipping the machine forward observe the ”Two minute rule”. 8011-027 4. Remove and dispose of the spring clips (1) (locking washer type) that hold the blade shaft (2) in place (see the illustration). 5. Inspect the blade shafts and replace if bent or worn. 6. Drive the blade shafts out towards the center.
MAINTENANCE Wear/Replacing delta blades Over time and due to wear, the blades will diminish in length. Once the blades have worn down by about ¾" (19 mm), the overall length of the blade at the longest point of the blade will be about 2 ½" (64 mm), and it will be necessary to replace the blades. the two screws with nuts holding the blade in place. Turn the new blade until it is properly aligned; see illustration. It is possible to replace delta blades without removing the rotor shaft.
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. Should this happen, perform an extra oil change on the engine. Remove the spark plug and turn the engine over a few revolutions with the starter handle before starting the engine again.
LUBRICATION Lubrication schedule 1. 2. 3. 4. Check engine oil daily, change every six months or 100 hours. Check and lubricate wheel bearings once a month. Lubricate folding handle points once a week. Lubricate main shaft bearings once a week or every 40 hours. 2 1 4 4 3 3 DT04-1 General Stop the engine and remove the ignition cable before attempting to lubricate the machine. Wipe away excessive grease after lubrication.
LUBRICATION 1. 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. 2. Handle Lubricate the joints at both sides of the handle with an oil can.
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 tank empty. Fill with fuel. Machine stored without observing proper procedure from chapter ”Storage/Winter storage” Clean tank, sludge reservoir and empty carburetor. Fill the tank with fresh fuel. Contamination, water or ice in fuel system.
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. Fuel stabilizers are an acceptable option to reducing sticky residues during storage. If alkylate gasoline (Aspen) is used, stabilizers are unnecessary because this fuel is stable.
