Safety regulations
General instructions
The workshop handbook is written for personnel who
are assumed to have general ride-on mower repara-
tion and service know-how.
The workshop where the ride-on mower is repaired
should be equipped with safety devices in
accordance with local regulations.
No-one should attempt to repair the ride-on mower
without having first read and understood the contents
of this handbook.
The machine is tested and approved only with the
equipment originally provided or recommended by
the manufacturer.
The below-mentioned boxes are included in this
workshop handbook, as is appropriate.
Special instructions
The fuel used in the ride-on mower has the
following hazardous characteristics:
• Toxic fluid and fumes
• Can cause eye and skin complaints
• Can cause breathing difficulties
• Highly flammable
When using compressed air, do not direct the
compressed air stream towards your, or anybody
else's, body. Air can be forced into the blood
stream, thereby constituting a danger to life.
Use eye protection when working with tensioned
springs.
Use hearing protectors when test driving.
After test driving, do not touch the silencer before it
has cooled down. Risk of burn injuries. This
especially applies if the ride-on mower is equipped
with a catalytic converter. If consumed, the lining on
and in the catalytic converter element is dangerous
to health. Use protective gloves when working with
the catalytic converter/silencer.
The blades are sharp and can cause cutting
injuries. Always use protective gloves when you are
handling the blades.
Use protective glasses when working with the
mowing deck. If the belt's tension spring comes off
and flies upwards, this can cause injury to persons.
Use eye protection when working with the battery
with the plugs removed.
Be extra careful when handling battery acid. Spilling
acid on the skin can cause severe burn injuries. If
acid is spilt on the skin, rinse immediately with
water. If acid gets into the eyes, this can cause
blindness. Contact a doctor.
Be careful with the maintenance of the battery.
Explosive gas is formed in the battery. Never
handle the battery when smoking or in the vicinity of
naked flames or sparks. Otherwise, the battery can
explode and cause severe injuries.
IMPORTANT INFORMATION
This box indicates a risk of damage to the
material if the instructions are not
followed.
WARNING!
The warning box indicates a risk
of injury to persons if the
instructions are not followed.
IMPORTANT INFORMATION
Waste oil and old filters should be handled
as hazardous waste.
