WARNING: Always keep the nut (3) tight that holds the blade (1). A loose nut or blade can cause an
accident.
9.Tighten the nut (3) that holds the blade (1) to a torque of 30 foot pounds (41,5 Nm).
10.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 cut- ting 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 8) 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 9) 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 the replacing the belt does not correct the problem, take the unit to an auth- orized service centre.
8.Move the blade rotation control to the DIS- ENGAGE position. Stop the engine.
9.(Figure 10) Check the operation of the blade brake. Rotate the pulleys with your hand. Make sure the brake pads (7) are pressed tightly against the pulleys
WARNING: If the brake pads (7) do not press tightly against the pulleys, take the unit to an author-
ized service centre.
10.(Figure 8) Move the blade rotation control to the ENGAGE position (2).
11.(Figure 10) Check the pads for the blade brake (7). If the pads are excessively worn or damaged, replace the brake pad assem- blies. Correct replacement parts and assist- ance 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 blades continue to ro- tate, engage and disengage the blade rotation control five times to remove any ex- cess rubber from a new mower drive belt. If you need assistance, take the unit to an authorized service centre.
14.(Figure 9) 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 18)
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 11)
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”.
