7. Safety parts for periodic replacement
7. Safety parts for periodic replacement(T218341-001-0E)
For the long-term safe operation of the machine, we ask you to inspect and service it regularly. However it is difficult to
evaluate the lifespan of parts by external visual inspection, so certain important parts such as the parts related to a fire
should be replaced at set intervals regardless of their apparent condition. If inspection and servicing reveals any
abnormality whatever in these parts, replace them even before their regulation time.
Ask your authorised KATO dealer to carry out the replacement of these safety parts.
Fuel system: Every 2 years or 4000 hours of operation, whichever reaches sooner.
・Fuel hose (fuel tank – fuel filter – engine – fuel tank, fuel pump related)
Hydraulic system: Every 2 years or 4000 hours of operation, whichever reaches sooner.
・Pump suction hose (oil reservoir ―hydraulic pump)
・Pump discharge hose (hydraulic pump ―control valve)
・Line hose for swing motor (control valve ―swing motor)
・Line hose for boom cylinder (control valve ―boom cylinder)
・Line hose for arm cylinder (control valve ―boom piping, boom piping ―arm cylinder)
・Line hose for bucket cylinder (control valve ―boom piping, boom piping ―bucket cylinder)
・Engine oil remote hose
・Additional attachment hose
Cooling system: Every 2 years or 4000 hours of operation, whichever reaches sooner.
・Heater hose (engine ―air conditioner unit)
Inside the engine compartment: Every 5 years
・Sound absorbing material
Others: Every 3 years
・Seatbelt
You must also inspect hydraulic hoses and fuel hoses during the following regular inspections.
Inspection interval Inspection item
Preoperational
inspection ・Oil leakage from the joints and caulked sections of fuel or hydraulic hoses
Monthly inspection ・Oil leakage from the joints and caulked sections of fuel or hydraulic hoses
・Damage to fuel or hydraulic hoses (cracks, wear, tearing)
Yearly inspection
・Oil leakage from the joints and caulked sections of fuel or hydraulic hoses
・Interference, collapse, deterioration, twisting, damage (cracks, wear, tearing)to fuel or
hydraulic hoses
(01EE-0018-0E)
1. Replace O-rings, gaskets etc. at the same time as you replace hoses.
2. If you find deformation or cracking of hose clamps when you inspect or replace hoses, you
should also replace the affected clamps.

For safe operation
(8) Do not put flammable items in the toolbox
Do not put aerosol spray cans, paint thinner, or other dangerous
combustibles in the toolbox.
They could cause a fire.
(9)Keep the safety signs clean
・If a safety sign is dirty
Use water or a neutral cleaner to remove the dirt. Do not use
gasoline or organic solvents.
・If it is not possible to remove the dirt, or if a safety sign is
damaged or peeling, replace the safety sign with new.
Refer to the parts list on the machine and order a new sign from
your authorised KATO dealer to replace the safety sign.
・When you replace a safety sign, always check that it is identical
to the original.
(10)Noise hazard
Working for extended periods in the vicinity of loud noise can
cause hearing damage.
・Wear earplugs or ear protection before working on the engine or
otherwise being exposed to loud noises for long periods.

WARNING 1. For safe operation
- 4 -
(11)Precautions inside the cab
Always keep the cab clean and organized.
・Remove any dirt or oils from the bottom of shoes before
entering the cab.
Not doing so could cause shoes to slip on the pedals, which
could cause an accident.
・Do not leave parts or tools around the operator's seat.
・Do not leave clear beverage bottles inside the cab or attach
suction cups to windows. These can act as lenses and cause a
fire.
・Do not listen to music on headphones, use a cell phone, or do
anything else that could impair operating ability while working
inside the cab.
・ Do not bring flammable, explosive, or other dangerous materials
into the cab.
・Make sure cigarettes and matches are completely extinguished

Adjust the operator's seat to fit you before you start the engine.
・Adjust the seat so that you can reach all control levers and
pedals comfortably with your back resting on the seat-back.
(13)Using the seatbelt
Tipping the machine over can cause serious injury or death,
such as by a severe impact inside the cab, being thrown from
the cab, or being trapped underneath the machine.
・When operating the machine, always sit in the operator's seat
and wear the seatbelt.
・When sitting down, check the seatbelt webbing, buckle, and
mounting hardware to make sure they function properly. If not,
replace the seatbelt.
Replace the seatbelt every 3 years, whether it is damaged or not.
