before starting the lawn mower for the first time.
Especially abide by the instruction for safe oper-
ation. If you do not, it may result in bodily
injuries.
If you have consumed intoxicating beverages,
are drowsy from medication, ill, or tired, never

Keep in mind that the operator or user is respon-
sible for any accident or hazard caused by the

Never perform operations other than those for
which the machine is designed. Operations the
mower is not designed for may cause damage to
the machine, shorten service life, or in the worst
case lead to a serious accident.
Never attempt unauthorized modification of the
machine as this could be very hazardous.
Take care as rotating one blade can cause other
blades to rotate.
Do not touch rotating blades.
Never step on the mower deck.
Be sure to alert them by signaling before you
make a new move when you are working with
co-workers.
While mowing, always wear substantial shoes
and long trousers. Do not operate the machine
barefoot or while wearing open sandals.
When operating, adjusting, or servicing the
machine, avoid wearing long loose clothes,
accessories or letting long hear hang loose,
which could be caught in rotating parts or on
projections. Be sure to use necessary protective
devices such as a headgear, safety glasses, ear
plugs, gloves, etc.
It is recommended to wear ear protectors such as
ear plugs, earmuffs, etc. But your ears should not
be plugged to the extent that horns of other
machines and call from other persons are inaudi-
ble.
Stop the blades and keep the mower in the trans-
port position when crossing surfaces other than
grass or when transporting it to and from the
area to be mowed.
It is not recommendable to operate the machine
on a slope.
Place the machine on level and hard ground
when servicing the machine or mounting or dis-
mounting the mower.
Stop the engine and remove the engine key when
servicing the machine or mounting or dismount-
ing the mower.
Be sure to apply the hydraulic lift lock without
fail when servicing the mower.
Use proper tools when servicing the machine.

poor service, which may result in unexpected
accidents during operation.
CHAPTER 1. FOR SAFE OPERATION

CHAPTER 1. FOR SAFE OPERATION
Service the machine in a place sufficiently illu-
minated in order to avoid unexpected accidents.
The engine, muffler, radiator, etc. are very hot
just after operation, so wait until those heated
parts cool down sufficiently to avoid burns.
Avoid high-pressure fluids. Escaping fluid under
pressure can penetrate the skin and cause serious
injury, so keep hands and body away from pin
holes and nozzles ejecting such fluids. Be sure to
consult your dealer about any hydraulic and fuel
injection system trouble.
In any hydraulic fluid is injected accidentally
into the skin, it must be removed within a few
hours by a doctor familiar with this type of
injury.
Keep all nuts, bolts and screws tight to be sure
that the equipment is in safe working condition.
Be sure to reinstall the removed parts in place.
A first aid kit and a fire extinguisher should be
kept in a place always in instant access.
Be sure to wear safety glasses and gloves when
servicing the machine.
