１５． Handling the High Pressure Hose
*SAFETY PRECAUTIONS
・Only use high pressure
hoses designed for a working pressure of 70 MPa
, manufactured by RIKEN.
・Use a hose equal to or greater the rated minimum curve radius (R). Also,
install the hose
so that the
rated
minimum curve radius
is maintained even when internal pressure causes the hose to move.
・RIKEN manufacture 2 types of flexible high pressure hose, one made from rubber and the other from nylon.
・RIKEN can also supply an anti-spatter hose designed to prevent the adherence of welding spatter.

WARNING
”
Do not grip the hose when pressure is being applied to the hose
. Should the high
pressure hose burst while being gripped, high pressure hydraulic oil will suddenly be dispersed,
which could penetrate the hand or other bodily part,
causing serious injury or even death to occur
.

The hose will expand and contract due to
internal pressure, so ensure slack exists
when installing the hose.
Do not move the pump or cylinder around
by pulling the high pressure hose.
Should the high pressure hose contact the floor or
another surface, it could suffer from frictional damage
caused by the expansion, contraction, and vibration
that occurs when the hose internal pressure is applied.
Protect the hose using a support or cushion.
Do not run over the hose with a cart or other vehicle.
Also do not drop heavy items onto the high pressure
hose. Ensure the high pressure hose is protected from
all conceivable dangers.
