IMPORTANT

Since the resistance of the nylon cutter is larger than that of the metal cutter, wrong operation of the nylon cutter will cause the clutch to overheat, deform and be damaged. When using the nylon cutter, carefully note the following.

•Use ZENOAH’s genuine nylon cutter. When using a commercially-available nylon cutter, make sure that it is no longer than 10 cm in external shape.

•Make sure that the length of the nylon cord is 17 cm or shorter.

•Keep the engine rotating at high speed while working.
