To examine the cutting equipment

WARNING: To prevent accidental start

plug.

WARNING: Use protective gloves when you

do maintenance on the cutting equipment.

The blade is very sharp and cuts can easily

occur.

1. Examine the cutting equipment for damage or

cracks. Always replace a damaged cutting

equipment.

2. Look at the blade to see if it is damaged or blunt.

Note: It is necessary to balance the blade after it is

sharpened. Let a service center sharpen, replace and

balance the blade. If you hit an obstacle that causes the

product to stop, replace the damaged blade. Let the

service center estimate if the blade can be sharpened or

must be replaced.

To replace the blade

1. Lock the blade with a block of wood.(Fig. 33 )
2. Remove the blade bolt (A).(Fig. 34 )
3. Remove the blade (B).
4. Examine the blade support (C) and blade bolt to see

if there are damages.

5. Examine the engine shaft to make sure that it is not

bent.

6. When you attach the new blade, make sure that the

angled ends of the blade point in the direction of the

cutting cover.(Fig. 35 )

7. Put the friction washer (D) and the blade against the

blade support (C).

8. To put the blade at the center of the engine shaft,

make sure that you can see the blade support marks

on each side of the blade.

9. Lock the blade with a block of wood. Attach the

spring washer (E) and tighten the bolt and washer

with a torque of 80 Nm.(Fig. 36 )

10. Pull the blade around by hand and make sure it turns

freely.

WARNING: Use protective gloves. The

occur.

11. Start the product to do a test of the blade. If the

blade is not correctly attached, there is vibration in

the product or the cutting result is unsatisfactory.
