SAFETY INSTRUCTIONS
Safety Instructions
General Instructions
This workshop manual is written for personnel with general knowledge about the repair and service of riders.
The workshop where the rider is to be repaired must be equipped with safety equipment in accordance with
local bylaws.
No one may repair the rider unless they have read and understood the content of this workshop manual.
The machine is tested and approved only with the equipment originally provided or recommended by the
manufacturer.
This workshop manual contains the following boxes in relevant places.
Special Instructions
The fuel used in the rider has the following hazardous properties:
• The fluid and its vapour are poisonous.
• Can cause eye and skin irritation.
• Can cause breathing problems.
• Is highly inflammable.
When using compressed air, do not direct the jet towards the body. Air can penetrate into the blood
circulation system, which entails mortal danger.
Use eye protection when working with tensioned springs.
Wear protective earplugs or earmuffs when test running.
After test running, do not touch the muffler until it has cooled. Risk for burns. This is especially true if the
rider is equipped with a catalytic converter. The coatings on and in the catalytic converter element are
hazardous to ingest. Use protective gloves when working with the converter/muffler.
The blades are sharp and can cause cuts and gashes. Use protective gloves when handling the blades.
Use eye protection when working with the cutting unit. The belt tensioning spring can break, fly off, and
cause personal injury.
Use eye protection when working with the battery with the plugs removed. Be especially careful when
handling battery acid. Acid on the skin can cause serious corrosive injuries. In the event of spillage on the
skin wash immediately with water.
Acid in the eyes can cause blindness; contact a doctor immediately.
Be careful when servicing the battery. Explosive gases form in the battery. Never perform maintenance on
the battery while smoking or in the vicinity of open flames or sparks. This can cause the battery to explode
and cause serious injuries.
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.
!
IMPORTANT INFORMATION
Waste oil and old filters shall be handled as hazardous waste.

Checking the Transmission
Oil Level
Remove the transmission cover. Loosen both
screws (one on each side) and lift off the
transmission cover.
Leave the cover removed for now.
Check that there is oil in the transmission’s oil
tank. Top up if needed with engine oil SAE
10W/30 (class SF-CC).
Wheels
Fit the wheels (certain markets).
The air pressure should be 60 kPa/
0.6 kp/cm2/8.5 PSI for all wheels.
In order to improve drive power, the pressure
in the rear tyres can be reduced to 40 kPa/0.4
kp/cm2/5.6 PSI.
The highest permitted pressure is 100 kPa/
1.0 kp/cm2/14 PSI.
In those cases where wheel weights are
delivered with the machine, it is the dealer’s
responsibility to fit them. Wheel weights are
normally fitted to the rear wheels.
