Periodic Replacement of Safety Related
Components
Routinely replace important parts concerned with safety. It
is difficult to determine by visual inspection or from
operation the service life of specific parts, so routinely
replace them as important parts every 2 years.
Table 2. Fuel System
Table 3. Hydraulic System
If any abnormality is found with any of these parts before
the replacement time, repair or replace as you would do
normally.
When replacing the hoses, if the hose clamps are found to
be deformed or cracked, replace the clamps at the same
time as the hoses.
Regarding hydraulic hoses not included in the routine
replacement of safety parts, carry out the inspection
described
K Table 4. ( T 3-15). Retighten, replace, etc,
when any abnormality is found.
Note: Replace O-rings, gaskets at the same time as
hoses. Contact your JCB distributor for replacement of
safety parts. Carry out inspection of the hydraulic hoses
and fuel hoses at the routine inspection described
