Safety Instructions
General directions
This workshop manual is written for personnel with
a general knowledge of repairing and servicing
Rides.
The workshop where the Rider is to be repaired
must be equipped with safety devices in
accordance with local bylaws.
NoonemayrepairtheRiderwithoutrstreading
and understanding the content of this workshop
manual.
This machine has been tested and approved
only together with the equipment supplied or
recommended by the manufacturer.
This Workshop Manual contains the following
warning boxes in relevant places.
WARNING!
The warning box warns of the
risk of personal injury if the
instructions are not followed.
IMPORTANT INFORMATION
This box warns of material damage if the
instructions are not followed.
Special directions
The fuel used in the Rider has the following
hazardous properties:
• Theuidanditsvaporaretoxic.
• Can cause eye and skin irritation.
• Can cause respiratory problems.
• Highlyammable.
When using compressed air, do not direct the air jet
toward your body. Air can penetrate into the blood
circulation, which means mortal danger.
Use eye protection when working on tensioned
springs.
Use ear protection during testing.
Duringtesting,donottouchthemu󰀪erbeforeithas
cooled down. Risk of burns. This is especially true if
the Rider is equipped with a catalytic converter. The
lining on and in the catalytic converter element is
toxic for consumption. Use protective gloves when
workingonthecatalyticconverter/mu󰀪er.
The blades are sharp and can give cut injuries. Use
protective gloves when handling the blades.
Use eye protection when working on the cutting
unit.Thebelttensioningspringcanbreak,yo󰀨
and could cause personal injury.
Use eye protection while you are working with the
battery. Take care when handling battery acid. Acid
on skin can cause serious burns. In the event of
spillage on the skin, wash immediately with water.
Acid in eyes can result in blindness, seek medical
aid.
Be careful when servicing the battery. Explosive
gases are formed in the battery. Never carry out
service on the battery while smoking or in the
vicinityofnakedamesorsparks.Thebatterycan
then explode and cause serious injury.
IMPORTANT INFORMATION
Waste oil and old lters shall be handled
as hazardous waste.

Outline sketch of the operation of the articulated steering.
Steering
All Riders in the Rider range have articulated steering. The force from the steering wheel is transferred to the
rear carriage via cables and a chain. This makes the Rider easy and precise to steer. A Rider mows easily
around all the obstacles on the lawn.
The turning radius is very small thanks to the articulated steering.
Rider machines have steering column mounted in ball bearings (1).
