OPERATING THE TRIMMER

•Adjust handle to a convenient position for cutting

as instructed on page 6.

•Allow the engine to warm up at a fast idle for a

few minutes.

OPERATING INSTRUCTIONS (METAL

BLADES and OPTIONAL NYLON LINE)

Your brushcutter/trimmer, has been designed and

constructed to give you years of trouble-free

service and relieve you of the many back-aching

tasks normally associated with grass trimming,

weed control and brushcutting. Nevertheless, in

common with all other power operated tools, the

Owner and/or Operator has a definite responsibility

to maintain the safe working condition of the unit as

provided by the manufacturer, and to ensure also

the safe operating procedures as prescribed by

common sense and this manual. Please, therefore,

read and understand the instructions as listed

hereunder, and on Page 3, in order to prevent

accidents and possible injury.

WARNING DANGER

••

•BEFORE STARTING UP THE ENGINE,

MAKE SURE THAT THE CUTTER BLADE IS

NOT CONTACTING ANYTHING.

••

•WHEN TWO OR MORE OPERATORS ARE

WORKING TOGETHER, ENSURE THAT A

SAFE DISTANCE IS KEPT BETWEEN THEM.

WARNING DANGER

GRASS/WEED TRIMMERS CAN THROW

GRAVEL, STONE, WOOD CHIPS, GLASS,

AND PLASTIC OR METAL OBJECTS. THE

DEBRIS SHIELD BEHIND THE TRIMMER

HEAD STOPS MUCH OF THE DEBRIS, BUT

CANNOT PREVENT THE OPERATOR FROM

BEING STRUCK BY SOME DEBRIS. READ

THE RULES FOR SAFE OPERATION IN THE

OPERATOR’S MANUAL THAT YOU

RECEIVED WITH YOUR ECHO TRIMMER.

ALSO, FOLLOW AII INSTRUCTIONS IN THIS

INSTRUCTION SHEET.

OPERATING INSTRUCTIONS NYLON

LINE

1. Always use the end of the line for cutting.

Forcing the cutter head too close to the work will

result in reduced efficiency and broken line.

2. Maintain the line at the recommended length of

12.5 to 15 cm (5 to 6 in).

A longer line will reduce engine speed, a shorter

line may result in engine damage.

3. The trimmer head rotates counterclockwise.

Always cut with the head tilted to the right to

deflect debris away from the operator.

4. Always observe the SAFETY RULES on Page 3

when using the unit.
