High-pressure oil leaking from a
small hole can penetrate the skin and
can cause blindness if it comes into
direct contact with the eyes. If you are injured by a stream of high-pressure oil
hitting your skin or eyes, flush with clean water and contact a doctor immediately
for treatment.
B.
Safe Handling of High Pressure Hoses
If oil or fuel leaks from a high-pressure hose, it can cause a fire or malfunction in
operation, resulting in serious injury or damage. If a loose bolt is found, stop work
and tighten the bolt to the specified torque. Never weld the machine without
isolating the hydraulic oil lines (hoses). If any damage is found to the hose, stop the
operation immediately and contact your Yuchai dealer.
Replace the hose if the following problems are found.
1)
Damaged or leaking hydraulic hose fittings.
2)
Worn or broken cladding, or reinforcement wire exposed.
3)
Swelling of the cladding in some places.
4)
Twisted or crushed movable parts.
5)
Impurities in the package.

Safety rules for high-temperature fluids
Hydraulic oil that has not been cooled during or after operation is hot and high
pressure. When checking or draining the oil, wait for the oil to cool until you can
touch the cover before operate to prevent burns caused by the sprayed oil or by
contact with hot parts. Even if the oil has cooled, slowly loosen the hydraulic tank
air filter to drain the pressure inside the hydraulic tank before removing the cover.
