• Check that the cutting attachment guard is not
damaged. Replace the cutting attachment guard if it
has been exposed to impact or is cracked.
• Only use original spare parts.
To check the blade
The blade is designed and manufactured to withstand
the loads that edging of a lawn involves.
• Check the blade for damage or cracks. A damaged
blade should always be replaced.
To check the support flange
• Check that the support flange is not cracked due to
fatigue or due to being tightened too much. Discard
the support flange if it is cracked.
To check the locknut
CAUTION: The nylon lining inside the
locknut must not be so worn that you can
turn it by hand. The lining should offer a
resistance of minimum 1.5 Nm / 13 in-lb.
The locknut must be replaced after it has
been put on approximately 10 times.
To assemble the bevel gear
1. Insert the driveshaft into the bevel gearbox housing.
Turn the cutting attachment so that the shaft
engages in the bevel gear.
2. Attach the bevel gear box to the shaft tube aligning
the positioning holes.

The locknut secures the cutting attachment on the
output shaft. Protect your hand from injury when
assembling, use the cutting attachment guard as
protection when tightening with a socket wrench.
1. When fitting, tighten the locknut in the opposite
direction to the direction of rotation of the cutting
attachment. To remove it, undo the locknut in the
same direction as the cutting attachment rotates.
2. Tighten the locknut using a socket wrench to 15-20
Nm / 11-20 ft-lb.
Safety instructions for maintenance
• Always stop the engine before you work on any part
of the cutting equipment. This continues to move
even after the throttle is released. Check that the
cutting equipment has stopped completely and
remove the HT lead from the spark plug before you
start any work on it.
• Always wear heavy-duty gloves when repairing the
cutting attachment. This is extremely sharp and can
easily cause cuts.
• Use only original spare parts for repairs.
• Store the product out of reach of children.
Assembly
3. Fasten the screw (A), then fasten the clamp bolt (B)
firmly, 6-8 Nm / 53-70 in-lb.
CAUTION: The locknut has a left-hand
thread. To tighten the locknut to much can
cause damage to the threads.
WARNING: Read the safety instructions that
follow before you do maintenance on the
attachment.
