General Instructions

This workshop manual is written for personnel with a general 
knowledge of repairing and servicing ride-on mowers.

The workshop where the ride-on mower is to be repaired 
must be equipped with safety devices in accordance with 
local bylaws.

No one may repair the ride-on mower without first reading 
and understanding 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 warning boxes 
in relevant places.

WARNING!  The warning box warns of the 
risk of personal injury if the instructions are 
not followed.

IMPORTANT!

This box warns of material damage if the instructions are 
not followed.

Special Instructions

The fuel used in the ride-on mower has the following 
hazardous properties:

•  The fluid and its vapor are toxic.

•  Can cause eye and skin irritation.

•  Can cause breathing problems.

•  Is highly flammable.

When using compressed air, do not direct the jet toward your 
body. Air can penetrate into the blood circulation, which can 
be fatal.

Use eye protection when working with tensioned springs.

Use hearing protection during testing.

During testing, do not touch the muffler before it has cooled 
down. Risk of burns. This is especially true if the ride-on 
mower 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 could 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.

IMPORTANT!

Waste oil and used oil filters shall be handled as 
environmentally hazardous waste.
