IMPORTANT!
All servicing and repair work on the machine requires special
training. This is especially true of the machine ' s safety
equipment. If your machine fails any of the checks described
below you must contact your service agent. When you buy
any of our products we guarantee the availability of
professional repairs and service. If the retailer who sells your
machine is not a servicing dealer, ask him for the address of
your nearest service agent. The life span of the machine can
be reduced and the risk of accidents can increase if machine

Throttle lock
• Make sure the throttle control is locked at the idle setting
when the throttle lock is released.
• Press the throttle lock and make sure it returns to its
original position when you release it.
• Check that the throttle control and throttle lock move freely
and that the return springs work properly.
The throttle lock is designed to prevent accidental operation
of the throttle control. When you press the lock (A) (i.e. when
you grasp the handle) it releases the throttle control (B).
When you release the handle the throttle control and the
throttle lock both move back to their original positions. This
movement is controlled by two independent return springs.
This arrangement means that the throttle control is
automatically locked at the idle setting.
