INFORMATION

This machine is equipped with an Overload Cancellation

Mechanism.

When the cutting blades have got into metal wires or those

twigs difficult to cut, the mechanism acts as a shock

absorber, and protects the drive gears and the blades from

severe reaction which could give damage to those parts.

When the blades are frequently caught by twigs, please

check the following points:

1. Size of the twigs. NEVER TRY TO CUT TWIGS

THICKER THAN 3/16” (5mm).

2. Condition of the blade edges. REPLACE THE WORN

OUT BLADES.

For the detail of the mechanism, please see below.

Thank you for choosing our product.

to ensure that neither the cutting part nor the

throttle come into contact with any obstacle
