Cutterblade Removal
WARNING: PREVENT ACCIDENTS -
ALWAYS switch off the engine, apply the parking
brake and remove the ignition key before working on
the cutterblades. The cutterblades have sharp edges.
Wear strong gloves to protect the hands when work-
ing on the cutterblades.
DO NOT operate tools towards the cutting edges to
avoid the risk of injury should the tool slip. Always
use genuine Hayter replacement parts.
The condition of the cutterblades and their mountings
should be checked regularly for signs of wear or dam-
age. Ensure that the cutterblades are not bent or cracked.
IMPORTANT: PREVENT DAMAGE -
Damaged or excessively worn cutterblades will cause
the cutting mechanisms to be out of balance. This
will cause excessive vibration and may lead to break-
age. DO NOT use unbalanced cutterblades.
