Power switch

The power switch should be used to start and stop the
machine.
Checking the power switch
• Start the machine, release the power switch and
check that the engine and the cutting blade stop.
• A defective power switch should be replaced by an
authorized service workshop.
Power switch lock
The power switch lock is designed to prevent accidental
operation of the switch. When the lock (A) is pressed in
the power switch (B) is released.
MACHINE´S SAFETY EQUIPMENT
The power switch lock remains depressed as long as the
power switch is depressed. When the grip on the handle
is released both the power switch and power switch lock
are reset. This movement is controlled by two
independent return springs. This position results in the
machine stopping and the power switch being locked.
Checking the power switch lock
• Make sure the power switch is locked when the power
switch lock is in its original position.
• Press in the power switch lock and make sure it
returns to its original position when you release it.
• Check that the power switch and power switch lock
move freely and that the return springs work properly.
• Switch on the machine, release the switch, and check
that the engine and blades stop.
Gradual start and overload protection
The machine is equipped with electronically controlled
gradual start and overload protection.
The engine starts to pulsate if the machine is loaded
above a specific level. If the load is reduced the engine
reverts to its normal state and cutting can resume.
The electronics will cut the current after a set time if the
machine continues to be run with a pulsating engine. The
higher load the faster the shutoff.
The electronics cut the current immediately if the blade
jams.
