CORRECT USE OF CHAIN BRAKE
The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your area of
operation. You should inquire through local government offices, your employer or your local dealer to ensure that your
chain saw conforms to the required safety standard. Echo chain brakes have been designed and tested to comply with
international safety standards as follows.
USA: ANSI Standard B175.1-2000 Safety Requirement for chain saws
Canada: CSA Standard Z 62.1 CHAIN SAWS
WARNING :
ANSI Standard B175.1-2000 stipulates that the brake shall stop the chain in 0.10 seconds (one tenth) at an engine
speed of 8000 RPM. It is the responsibility of the Owner/Operator to ensure that the brake is serviced, adjusted and
tested strictly in accordance with the instructions as detailed herein in order to ensure that the brake performance is
maintained in compliance with the Standard B175.1-2000.
INSTALLATION
Echo recommends that the chain brake should be
serviced by an authorized Echo servicing dealer.
OPERATION
Set the lever in the released position before starting to
cut.
If the brake is tripped by kick back reaction, the chain will
stop. Immediately release the throttle to avoid possible
damage to the engine or clutch.
Do not attempt to operate the engine with the brake
engaged.
TESTING THE BRAKE
Start the engine on a solid level surface and run at a fast
idle until warm.
Hold the saw firmly by the handles and accelerate the
engine to a fast idle.
Slowly operate the chain brake lever while holding the
saw firmly on the ground. When the brake lever trips, the
chain should stop. Immediately release the throttle
trigger.
CAUTION
DO NOT ALLOW THE SAW TO TIP FORWARD IN ORDER TO
AVOID DAMAGE TO THE CHAIN.
If the chain does not stop, immediately return the saw to your
authorized Echo dealer for repair.
Function:
When the lever is pushed forward, chain brake
instantly works to stop the chain.
Release:
When the lever is fully pulled toward the operator, brake is
released.
