ASSEMBLY

Correct height

Adjust the harness so that the cutting at- tachment is parallel to the ground.

Correct balance

Let the cutting attachment rest lightly on the ground. If you use a grass blade, it should balance about 10 cm above the ground to prevent contact with stones and the like. Adjust the position of the harness clamp to balance the unit correctly.

Fitting blades and trimmer heads

SWhen fitting the cutting attachment it is extremely important that the raised section on the drive disc/support flange engages correctly in the centre hole of the cutting attachment. If the cutting attachment is fitted incorrectly it can result in serious and/ or fatal personal injury.

WARNING: Never use a cutting attachment without an approved guard. See the section on Techni- cal data. If an incorrect or faulty guard is fitted this can cause seri- ous personal injury.

IMPORTANT!

If a grass blade is to be used, the machine must be equipped with the correct handle- bar, blade guard and harness.
