MAINTENANCE

Checking the V-belts

Check every 100 hours of operation. Check for severe cracking and large nicks.

NOTE: The belt will show some small cracks in normal operation.

The belts are not adjustable. Replace belts if they begin to slip from wear.

Checking the Blade

In order to attain the best mowing effect, it is important that the blade is well sharpened and not damaged.

Always use protective gloves when handling the blade.

A bent or cracked blade or blade with large nicks should be replaced.

Check the blade mounts.

IMPORTANT INFORMATION

The sharpening of the blade should be carried out by an authorized service workshop.

A damaged blade should be replaced when hitting obstacles that result in a breakdown. Let the service workshop decide whether the blade can be repaired/ground or must be replaced.
