Inspect Blade (Figure 19)
WARNING: Before you inspect or remove the blade, disconnect the wire to the spark plug. If the blade
hits an object, stop the engine. Check the unit for damage. The blade has sharp edges. When you hold the blade, use gloves or cloth material to protect your hands.
If you keep the blade (1) sharp and inspect the blade for damage, the blade will cut better and be more safe to operate. Frequently check the blade for excessive wear, cracks, or other damage. Frequently check the nut (3) that holds the blade (1). Keep the nut (3) tight. If the blade hits an object, stop the engine. Disconnect the wire to the spark plug. See if the blade is bent or damaged. Check the blade adapter (5) for damage. Before you operate the unit, replace damaged parts with original equipment parts. See the authorized service centre in your area. Every three years, have an authorized service person inspect the blade or replace the old blade with an original equipment part.
How To Remove And Install The Blade (Figure 19)
1.Remove the mower housing. See the instruc- tions on “How To Remove The Mower Hous- ing”.
2.Use a piece of wood to keep the blade from rotating.
3.Remove the nut (3) that holds the blade (1).
4.To remove the blade (1) from the air assist fan (8), remove fasteners (9) and (10).
5.Check the blade (1) and the blade adapter
(5) according to the instructions for “Inspect
Blade”. Check the air assist fan (8) for dam- age. Replace badly worn or damaged parts with original equipment parts. See an author- ized service centre in your area.
6.Clean the top and bottom of the mower hous- ing. Clean the air assist fan (8). Remove all the grass and debris.
7.Assemble the blade (1) and air assist fan
(8) with fasteners (9) and (10). Tighten the bolt (9) that holds the blade (1) to a torque of 6,8 N-m (5 foot pounds).
8.Mount the blade (1) and blade adapter (5) on the mandrel (6).
F-040730L
9.Mount the blade (1) so that the hi-lift edges
(7) are up. If the blade is upside down, the blade will not cut correctly and can cause an accident.
10.Fasten the blade (1) with the original washers and nut (3). Make sure the outside rim of the Belleville washer (2) is against the blade (1).
WARNING: Always keep the nut (3) tight that holds the blade (1). A loose nut or blade can cause an
accident.
11.Tighten the nut (3) that holds the blade (1) to a torque of 41,5 N-m (30 foot pounds) .
12.Install the mower housing. See “How To Re- move The Mower Housing”.
How To Adjust The Blade Rotation Control
WARNING: To prevent an injury, the blade rotation control must operate correctly.
In normal usage, the blade rotation control will not require an adjustment. However, if the cutting performance decreases or the quality of cut is poor, make the following changes.
1.When you mow, make sure the throttle con- trol in in the FAST position.
2.(Figure 20) Move the blade rotation control to the DISENGAGE position (1).
3.Stop the engine. Disconnect the wire from the spark plug.
4.Check the blade(s). Keep a sharp edge on the blade(s). A blade that is not sharp will cause the tips of the grass to become brown.
5.(Figure 21) Disconnect the blade drive spring (2) from the blade control rod (1). Move the blade drive spring (2) to the middle hole (4). This will increase the tension on the mower drive belt.
6.Attach the wire to the spark plug. Mow for a short distance and again check the quality of cut. If necessary, move the blade drive spring (2) to the bottom hole (5)
7.Again check the quality of cut. If the quality of cut has not improved, replace the mower drive belt. See “How To Replace The Mower Drive Belt”. If replacing the belt does not cor- rect the problem, take the unit to an author- ized service centre.
8.Move the blade rotation control to the DIS- ENGAGE position. Stop the engine.
9.(Figure 22) Check the operation of the blade brake. Rotate the mandrel pulley (5) with your hand. Make sure the brake pad (7) is pressed tightly against the mandrel pulley
(5).
WARNING: If the brake pad (7) does not press tightly against the man- drel pulley (5), take the unit to an
authorized service centre.
10.(Figure 20) Move the blade rotation control to the ENGAGE position (2).
11.(Figure 22) Check the pad for the blade brake (7). If the pad is excessively worn or damaged, replace the brake pad assembly. Correct replacement parts and assistance are available from an authorized service centre.

12.Attach the wire to the spark plug. Mow for a short distance and again check the operation of the blade rotation control.
13.When you move the blade rotation control to the DISENGAGE position, all movement will stop within five seconds. If there is move- ment of the belt or the blade(s) continue to rotate, engage and disengage the blade rota- tion control five times to remove any excess rubber from a new mower drive belt. If you need assistance, take the unit to an author- ized service centre.
14.(Figure 21) If you replace the mower drive belt, move the blade drive spring (2) to the top hole (3).
How To Adjust The Shift Lever (Figure 30)
If the NEUTRAL position on the shift lever does not match neutral on the gearbox, adjust the shift lever as follows.
1.Stop the engine.
2.Disconnect the adjuster nut (2) from the shifter bracket (3).
3.Make sure the shift lever is in the NEUTRAL position.
4.Push the unit forward. Make sure the gear- box is in neutral.
5.To align the adjuster nut (2) with the hole in the shifter bracket (3), turn the adjuster nut
(2).
6.Connect the adjuster nut (2) to the shifter bracket (3).
7.Make sure the NEUTRAL position on the shift lever matches neutral on the gearbox.
How To Check And Adjust The Clutch (Figure 23)
If the motion drive belt is loose, the clutch will slip when: going up a hill, pulling a heavy load, or the unit will not move forward. Adjust the clutch as follows.
WARNING: Before you make an in- spection, adjustment, or repair to the unit, disconnect the wire to the
spark plug. Remove the wire from the spark plug to prevent the engine from starting by accident.
1.Check the routing of the motion drive belt. Make sure the belt is installed correctly and is inside all the belt guides.
2.Remove the cotter pin (1), washer (2), and brake spring (3) from the adjustable nut
(4).
3.Disconnect the adjustable nut (4) from the brake lever assembly (5) and the parking brake latch (6).
4.Align the hole in the brake lever (5) with the hole in the frame. Hold the brake lever (5) in place with a 6 mm pin or bolt (7).
5.Pull the clutch rod forward until tight. Turn the adjustable nut (4) until the nut will fit through the hole in the brake lever (5).
6.Assemble the adjustable nut (4) to the parking brake latch (6), brake lever (5) and brake spring (3). Fasten with the washer (2) and cotter pin (1).
7.Remove the 6 mm pin or bolt (7).
8.If the belt still slips after the clutch has been adjusted, then the motion drive belt is worn or damaged and must be replaced. See “How To Replace The Motion Drive Belt”.
