•Understandthefunctionsofthecontrolsandgauges.
Familiarize yourself with their location and how to
operatethem.Understandthemeaningofallthe
symbols.
■Obey the worksite rules.
•Followtheworksiterulessuchasmattersforbiddenortobeattendedto,andworking
procedures.
■Wear protective clothing to suit the work.
•Wearclothing,safetyshoesandhardhattosuityourwork.

portions of the machine. Do not wear oily clothing.
•Accordingtothetypeofjobs,wearsafetygogglesormask.
■Know the work area in advance.
•Knowtheterrain,geologyandconditionsoftheroadsurfaceattheworksite.Startworking
after securing safety such as stationing a guardsman or putting up barriers where there is a
risk of falling of the machine or collapse of shoulder.
■Provide against an accident.
•Decideinadvancethemeansofcommunicationinanemergency.Knowthelocationand
use of an extinguisher and rst-aid kit.
■Know the capability of the machine.
•Thoroughlyunderstandtheperformanceofyourmachineandcorrectlyoperatethe
machine to meet the requirements of the job site. Operating the machine beyond its
capabilitiesmayleadtoanaccident.Useyourmachinewithinitscapability.
WARNING: Negligence of these instructions can lead to accidents.

■Do not use a machine which has not been serviced correctly at regular intervals.
•Beforeworking,performnecessaryinspections.Startoperationonlyaftermaking
certain the machine is in good operating condition. If found to be abnormal, report to the
responsible person and have the fault corrected. Operate the machine after making sure
that it is safe to operate.
■Do not allow anyone to enter the work area except for authorized personnel.
•Alwaysconducttheworkpayingattentiontothe
workers around the machine.
■Be careful of hot parts.
•Afteryourmachinehasoperatedforsometime,the
coolant, engine oil and hydraulic uid will become hot
and the pressure will build up. If, in this state, you try to
remove the ller caps, drain the oil or replace the lters,
you can get burned. Perform this work in accordance
with the correct procedures with the machine cooled
down.
•Toremovetheradiatorcap,slowlyloosenthecapto
relieve the pressure with the engine shut down and the
coolant cooled down. (For the radiator cap with a lever,
lift the lever to release the trapped pressure.)
•Whenremovingthellercaponthehydraulictank,releasethetrappedpressurebyturning
it out slowly to prevent the oil from gushing out.
•Donottouchthemufflerwhiletheengineisrunningorimmediatelyafterithasbeenshut
down.You can get burned.
■Be careful with re.
•Thefuel,oil,andanti-freezewillcatchreifopen
ames or ignition sources are used close to them.
Particularly, the fuel is highly ammable.
•Donotsmokeoruseamatchorcigarettelighterclose
to inammables (combustibles).
•Whenrefueling,stoptheengineanddonotsmoke.
•Thellercapsofthefuelandoiltanksmustbekept
tight.
WARNING: Negligence of these instructions can lead to accidents.

systems are under internal spressure. Do not perform
adding, draining, inspection or servicing of the hydraulic
systems until the internal pressure has been relieved.
Hydraulic uid leaking through a ne hole at high
pressure can penetrate your skin and eyes. Inspect
leakage by holding a hard board close to suspected
leaks wearing goggles. If affected by high pressure oil,
get medical help immediately.
■Be careful of hot parts

the coolant, engine oil and hydraulic uid will become
hot.
•Removingtheradiatorcapordrainingthecoolantor
oil can burn you. Perform this work in accordance with
correct procedures after the systems have cooled down.
■Use care when inspecting or servicing fan or belts in motion
