BEWARE OF CHIPS WHEN WORKING WITH HAMMER
Working with a hammer may cause a serious bodily accident
because of springing off of a pin or littering of metallic chips. Strictly
observe the following.
• Hitting a pin or the like may give rise to shattering of broken chips
to hurt people nearby. Before starting such a work, make it sure
that no one is staying around you.
• Knocking a pin off with a strong force may cause the pin flying out
to hurt a person nearby. Do not allow anyone to stay around.
• When knocking such a hard metallic part as pin or bearing, there
is a risk of causing a serious bodily accident by flying objects. Be
sure to wear protective equipment such as goggles, gloves and
helmet.
BE CAUTIOUS OF HEATED COOLANT
When checking or discharging the coolant, ensure that the radiator
cap has been cooled down so that it can be touched by bare hand
in order to prevent a burn injury because of the spewing hot water
or steam.
When removing the cap, first loosen it slowly to relieve radiator
internal pressure, and then take it off.
BEWARE OF OIL AT ELEVATED TEMPERATURES
When checking or discharging oil, ensure that the radiator cap and
plug have been cooled down so that they can be touched by bare
hand in order to prevent a burn injury because of the spewing hot
oil or coming in contact with parts heated at high temperatures.
When removing cap and plug, first loosen it slowly to relieve
radiator internal pressure, and then take it off.
BEWARE OF OIL UNDER HIGH INTERNAL PRESSURE
The hydraulic system is constantly subjected to an internal
pressure. Thus, when checking or replacing the piping and hoses,
failure to ensuring that the internal pressure of the circuit has been
relieved gives rise to a serious bodily accident.
Strictly observe the following.
• Never replace piping or hoses while the hydraulic circuit is
subjected to an internal pressure. Be sure to relieve the pressure
of the hydraulic circuit.
Refer to “Inspection and Maintenance 2. Basic Maintenance
(Hydraulic Equipment Handling)” for details.
• If an oil leakage is taking place, the piping, hoses and their
periphery are wet. Check to ensure that the piping is free from
fissures and the hoses have no cracking or swelling.
Be sure to wear protective equipment such as goggles and gloves
during the inspection work.
• High pressure oil leaking through a small hole may puncture the
skin or destroy eyesight upon direct contact. If this happens, wash
away with flowing clean water and see the doctor as soon as
possible.
