c. Periodic replacement of important parts
To ensure safety in traveling and operating the machine, the user is strongly requested to carry out
periodic inspection and servicing. For added safety, the following important parts, related to safety and fire
hazards in particular, must be replaced at their specified intervals.
With the passage of time, these parts easily get degraded in material or worn out. They are difficult to
check for anything unusual even at periodic inspection and servicing. Even if nothing unusual is found, it
is essential to replace them with new ones after their specified service life, in order to maintain complete
function.
If by any chance any of these parts gets in trouble even before its service life, it must be repaired or
replaced as usual.
In replacing the hoses, check also the hose clamps for deformation, cracks and other troubles. Replace
the hose clamps too with new ones, as required.
Check all the hydraulic hoses, including those to be replaced at regular intervals, for the following points.
Tighten up or replace them, as required.
When replacing the hydraulic hoses, change their O-rings and sealing for new ones at the same time.
• Check the fuel and hydraulic hoses too at the following periodic inspections.
