Regrinding and balancing of the cutter bar (figure Q )
WARNING
The regrinding and balancing of the cutter bar must be carried out by an
authorised workshop. An incorrectly ground and unbalanced blade can cause
strong vibrations and damage the lawn mower.
The cutting edges of the cutter bar may only be reground until the marking (1) on the
cutter bar (ring) (see figure
Q
) has been reached. Attention! Observe the grinding
angle of 30°.
Your workshop can check this value (wear limit) for you!
WARNING
A blade in which the wear limit (marking) has been exceeded may break and be
thrown away, which can lead to serious injuries.
Changing the cutter bar
WARNING
The replacing of the cutter bar must be carried out by an authorised workshop.
Due to an incorrectly assembled blade fastening or an excessively or
insufficiently tightened blade screw, the cutter bar may become loose, which
can lead to serious injuries.
–
For replacement, use only original cutter bars. Non-equivalent spare parts can
damage the machine and are a safety hazard.
–
Replacement cutter bars must be permanently marked with the name and/or
company logo of the manufacturer or supplier and the part number.
Servicing the wheels (figure S )
Lubricate the wheel bearings once a year or every 15-20 operating hours.

Langzeitfett LZR 2”, push the wheels back in place, attach the washer, fasten
using the hexagonal nut and tighten so that the wheels can turn easily but without
play. Reattach the wheel cap.
