Safety Measures During Maintenance
HIGH-PRESSURE HOSES
Neither bend high-pressure hoses nor hit them with hard objects. Do not
use piping or hoses with fissures, cracks, or bends, since they may burst
during operation.
Immediately replace any loose or damaged fuel or oil hoses. Leaking
fuel or oil involves danger of fire and slipping.
Replace all hoses every six years at the latest.
HANDLING HIGH-PRESSURE OIL
•
Always take into account that the hydraulic lines are subjected to high
pressure.
•
Do not top up oil, drain oil, or perform maintenance or inspection
measures unless the work unit is completely lowered and the system
is depressurised.
•
If oil comes out under high pressure, this involves danger of an oil jet
penetrating the skin or getting into the eyes. For this reason, always
wear safety goggles and thick safety gloves, and use a piece of
cardboard or wood when checking for oil leaks.
•
If you have been hit by an oil jet, immediately go and see a doctor and
explain what has happened.
HANDLING OF ALS-CONTROL PRESSURE ACCUMULATORS
WARNING
Danger of injury! Pressure accumulators are filled with highly
pressurised nitrogen.
Do not open or damage pressure accumulators.
•
Immediately inform your Komatsu dealer, if you detect malfunctions
or defects of pressure accumulators.
•
Filling pressure accumulators with gas or topping up gas in pressure
accumulators is strictly limited to either Komatsu service technicians
or other persons authorised to handle highly pressurised gas.
•
Do not hit against the pressure accumulator.
•
Keep naked light and sources of heat away from pressure
accumulators.
•
Do not drill holes into the pressure accumulator.
•
Do not weld parts to the pressure accumulator.
•
The service technicians must depressurise the hydraulic system before
they can remove the pressure accumulators.
•
The service technician must let the gas escape before they can
disassemble the pressure accumulator.
•
Have the gas pressure of the pressure accumulators checked either
every 1000 operating hours or once every year.
NOTE
In countries with a hot climate, the responsible Komatsu dealer must
check the gas-pressure of the pressure reservoir already every 650
hours.
