Hydraulic Hoses
Inspection of Hydraulic Hoses
When checking the hydraulic circuit for
pinhole leaks or oil leakage from nozzles, do
not use your hands. Use items such as paper
or corrugated cardboard to find leakage
points.
Be extremely careful with high-pressure oil as
it may pierce your skin, resulting in personal
accidents.
If fluid is injected into the skin it must be
surgically removed within a few hours by a
doctor familiar with this form of injury or
gangrene may result.
Check the pipes and hoses to make sure that
there is no oil leakage, circuit damage,
looseness, wear, connector looseness,
weather deterioration and chemical
deterioration.
Make any necessary repairs before operating
the machine.
Air Cleaner
Inspection of Air Cleaner
The air cleaner is a component that removes
dirt from the intake air to prevent wear of the
cylinder liners and piston rings so that the
engine will always operate smoothly.
A contaminated air cleaner element may
cause malfunction of the engine.
Make sure that there is no damage to the
air cleaner.
