RedMax SRTZ2500 Owner's/Operator's Manual page 2

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.
