acquainted with all the controls and the
safety procedures.
• Never allow children or people unfamiliar
with these instructions to use this
machine. Local regulations may restrict

and off the roads. Keep alert and aware at
all times. Watch out for traffic when
crossing or near roadways.

surfaces other than grass.
• Remember that some people are deaf or
blind and that children and animals can be
unpredictable.
• Keep travelling speeds low enough for an
emergency stop to be effective and safe at
2 SAFETY INSTRUCTIONS
all times, in any conditions.
• Remove or avoid obstructions in the area to
be cut, thus reducing the possibility of injury
to yourself and/or bystanders.
• When reversing, take special care to ensure
that the area behind is clear of obstructions
and/or bystanders. DO NOT carry
passengers.
• Keep in mind that the operator or user is
responsible for accidents or hazards
occurring to other people or their property.
• When the machine is to be parked, stored
or left unattended, lower the cutting means
unless the transport locks are being used.

fastened in the transport position. Do not
transport with cutting mechanism rotating.
• Drive the machine with due consideration of
road and surface conditions, inclines and
local undulations.
2.6 LEAVING THE DRIVING POSITION
• Park the machine on level ground.
• Before leaving the driving position, stop the
engine and make sure all moving parts are
stationary. Apply brakes and disengage all
drives. Remove the starter key.

• Release blockages with care. Keep all parts
of the body away from the cutting edge.
Beware of energy in the drive which can
cause rotation when the blockage is released.
• Keep other people away from the cutting units
as rotation of one cylinder can cause the
others to rotate.

MAINTENANCE
• Stop the engine and make sure all moving
parts are stationary.
• Apply brakes and disengage all drives.
