Ma Chine´s Safety Equipment; General - Husqvarna K 970 Operator's Manual

General

W ARNING! Never use a machine that has
!
faulty safety equipment! If your machine
fails any of these checks contact your
service agent to get it repaired.
The engine should be switched off, and the
stop switch in STOP position.
This section descr ibes the machine ' s safety equipment, its
purpose, and how checks and maintenance should be carried
out to ensure that it operates correctly.
Thr ottle lockout
The throttle tr igger lock is designed to prevent accidental
operation of the throttle. When the lock (A) is pressed in this
releases the throttle (B).
The trigger lock remains pressed in as long as the throttle is
pressed. When the grip on the handle is released the throttle
trigger and the throttle trigger lock both return to their original
positions. This is controlled by two independent return spring
systems. This means that the throttle trigger is automatically
locked in the idle position.
Chec king the throttle lockout
• Make sure the throttle control is locked at the idle setting
when the throttle lockout is released.
• Press the throttle lockout and make sure it returns to its
original position when you release it.
• Check that the throttle trigger and throttle lockout move
freely and that the return springs work properly.

Chec king the stop switch
• Start the engine and make sure the engine stops when

Vibration damping system
WARNING! Overexposure to vibration can
!
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
Such symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or
condition. These symptoms normally appear
in the fingers, hands or wrists. These
symptoms may be increased in cold
temperatures.
• Your machine is equipped with a vibration damping
system that is designed to reduce vibration and make
operation easier.
The machine ' s vibration damping system reduces the
•
transfer of vibration between the engine unit/cutting
equipment and the machine ' s handle unit. The engine
body, including the cutting equipment, is insulated from
the handles by vibration damping units.
