13. Tighten belt guides and refit the belt guard. MAINTENANCE 22 3.5" / 89mm Flail Blades Wear/Rotation/Replacing 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. Rotate the rotor shaft as follows: Rotating the rotor shaft 1. Allow the engine to cool. 2. Disconnect the spark plug. 3. Remove the belt guard (see illustration). IMPORTANT INFORMATION Only the flail blade rotor shaft can be rotated to achieve even wear. The spring tines and delta blades must be operated in the correct direction. 8011-006 A. New blade B. Worn blade C. After rotation Remove belt cover 4. Remove the belt guard and pulley from the rotor shaft (see illustration). 5. Remove the 6 bearing bolts and allow the rotor shaft to slide out. 6. Check the shaft, bearing, blade length, blade e-rings and spacers. 7. Rotate the shaft end for end. 8. Refit the bearing bolts. 9. Refit the pulley and check that it is aligned with top pulley. 10. Refit the drive belt. 11. Check the pulley alignment to the engine shaft pulley. The drive belt should run smoothly in its track. Adjust as necessary. Tighten the pulleys. 12. Refit the belt guard. 13. Reattach the spark plug cable. A B C 8011-027 MAINTENANCE 23 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 e-rings (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. The blades (4) and the plastic spacers (3) will fall off. 7. Fit the new blades and replace the plastic spacers as necessary. Refer to the illustration of the components for blade/spacer placement. 8. Install e-rings. 9. Repeat this procedure for the remaining three shafts. 10. Reattach the spark plug cable. IMPORTANT INFORMATION When tipping the machine forward observe the Two Minute Rule. 8062-020 1 4 3 2 8011-027 MAINTENANCE 24 Spring Tines Wear/Replacing Over time and due to wear, the tines will diminish in length. When the tines can no longer be adjusted to comb ." (6 mm) into the soil, the tines must be replaced. Delta Blades Wear/Replacing Over time and due to wear, the blades will diminish in length. Once the blades have worn down by about ." (19 mm), the overall length of the blade at the longest point of the blade will be about 2." (64 mm), and it will be necessary to replace the blades. It is possible to replace delta blades without removing the rotor shaft. Remove the delta blade by removing the two screws with nuts holding the blade in place. Turn the new blade until it is properly aligned; see illustration. Delta Blade Screws Nuts Spring Tine Screw Washers Spring tines can be replaced without removing the rotor shaft by using a ." socket wrench. Remove the screw and replace the spring tine using the wrench. NOTE: Do not use spring tines with bagger attachment. MAINTENANCE 25 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. Cleaning Regular cleaning and washing will increase the machine’s lifespan. Make it a habit to clean the machine directly after use, before the dirt sticks. Check before rinsing that the fuel tank lid is properly in place to avoid getting water in the tank. Use caution when using high-pressure spray because warning decals, instruction signs and the engine can be damaged. Do not exceed 70 bar/1000 PSI water pressure when cleaning. Lubricate the machine after cleaning. This is particularly important if the machine is to be stored. 8060-017 8011-121-1 LUBRICATION 26 2 4 3 3 1 2 Stop the engine and remove the ignition cable before attempting to lubricate the machine. Wipe away excessive grease after lubrication. It is important to avoid getting lubricant on the belt or the drive surfaces on the belt pulleys. Should this happen, attempt to clean them with spirits. If the belt continues to slip after cleaning, it must be replaced. Lubrication Schedule 1. Check engine oil daily, change every six months or 100 hours. 2. Check and lubricate wheel bearings once a month. 3. Lubricate folding handle points once a week. 4. Lubricate main shaft bearings once a week or every 40 hours. LUBRICATION 27 DT06 Blades Cover the blades with a thin coat of oil to avoid rust. This is particularly importan...
