GENERAL

Cautions on working on the machine

•  When performing maintenance on the machine, 

clean up the foot area and strictly observe the fol-

lowing so as not to fall:

•  Do not spill oil or grease.

•  Do not leave tools laying around.

•  When walking, watch your step.

•  Never jump off the machine. Use the steps and 

handrails when climbing on and off the machine, 

and always support your body at three points with 

your hands and feet.

•  Use protective equipment as required by job con-

ditions.

Use caution when fueling

•  Do not smoke or permit open flames while fuel-

ing or near fueling operations.

•  Never remove the fuel cap or refuel with the en-

gine running or hot. Never allow fuel to spill on 

hot machine components.

•  Maintain  control  of  the  fuel  filler  nozzle  when 

filling the tank.

•  Do not fill the fuel tank to capacity. Allow room 

for expansion.

•  Clean up spilled fuel immediately.

•  Tighten  the  fuel  tank  cap  securely.  Should  the 

fuel cap be lost, replace it only with the original 

manufacturerʼs  approved  cap.  Use  of  a  non-ap-

proved cap without proper venting may result in 

pressurization of the tank.

•  Never use fuel for cleaning purposes.

•  Use the correct fuel grade for the operating sea-

son.

Handling of hoses

Fuel, oil or hydraulic fluid leaks can cause a fire.

•  Do not twist, bend or hit the hoses.

•  Never use twisted, bent or cracked hoses, tubes 

and pipes. They may burst.

•  Retighten loose connections.

Be  careful  with  hot  and  pressurized 

components

Stop the engine and allow the machine to cool down 

before performing inspection and maintenance.

•  The  engine,  muffler,  radiator,  hydraulic  lines, 

sliding parts and many other parts of the machine 

are hot directly after the engine is stopped. Touch-

ing these parts will cause burns.

•  The  engine  coolant,  oil  and  hydraulic  fluid  are 

also hot and under high pressure.

  Be careful when loosening caps and plugs. Work-

ing on the machine under these conditions could 

result in burns or injuries due to the hot oil spurt-

ing out.

Be careful with hot cooling systems

Do not remove the radiator cap or drain plugs when 

the  coolant  is  hot.  Stop  the  engine,  let  the  engine 

and radiator cool and loosen the radiator cap or drain 

plugs slowly.
