PERIODIC REPLACEMENT OF RUBBER
HOSES
WARNING: Rubber hoses, such as hydraulic
hoses, lubrication hoses, fuel hoses, and heater
hoses, may break due to aging, fatigue, and
abrasion, possibly resulting in serious injury or
death.
In order to avoid serious personal injury, be sure
to replace the hoses listed in the following table
every two years, or 8000 hours of operation,
whichever comes first. Use genuine Hitachi parts.
It is very difficult to gauge the extent of
deterioration due to aging, fatigue, and abrasion
of rubber hoses by inspection alone. Thus, if
rubber hoses are not replaced periodically,
serious personal injury may result due to falls of
the front, penetration of high pressure oil into the
skin, or fire.
Regardless of regular replacement intervals, if
hoses are found to be defective by periodic
inspection (refer to pages 7-70 and 7-80), be sure
to repair or replace them before operating the
machine. Be sure to replace seals, such as
O-rings and hose clamps along with replacing
hoses.
Consult your authorized dealer for correct hose
replacement.
