OPERATION & MAINTENANCE MANUAL STE35SR
Dusty Jobsite
When working at dusty worksites, do as follows:
Clean the radiator fins and other parts of the heat exchange equipment more frequently, and
take care not to let the fins become clogged.
Replace the fuel filter more frequently.
Clean electrical components, especially the starting motor and alternator, to avoid
accumulation of dust.
When checking and replacing the oil or filters, move the machine to a place where there is no
dust and take care
To prevent dust from entering the system.
Avoid Mixing Lubricants
If a different brand or grade of oil has to be added, drain the old oil and replace all the
oil with the new brand or grade of oil. Never mix different brand or grade of oil.
Choose fuels and lubricants that match the ambient temperature
Must use fuels and lubricants that match the ambient temperature.
For details, see “Use of Fuels, Coolants and Lubricants according to ambient Temperature”.
Locking the Inspection Covers
Lock inspection cover securely into position with the lock bar. If inspection or maintenance is
performed with inspection cover not locked in position, there is a danger that it may be suddenly
blow shut by the wind and cause injury to the worker.
Hydraulic System - Air Bleeding
When hydraulic equipment has been repaired or replaced, or the hydraulic piping has been
removed and installed again, the air must be bled from the circuit.
Hydraulic Hose Installation
When removing parts at locations where there are O-rings or gasket seals, clean the
mounting surface, and replace with new parts. When doing this, be careful not to forget to
assemble the O-rings and gaskets.
When installing the hoses, do not twist them or bend them sharply. If they are installed so,
their service life will be shortened extremely and they may be damaged.
Checks After Inspection and Maintenance Works
If you forget to perform the checks after inspection and maintenance, unexpected problems may
occur, and this may lead to serious injury or property damage. Always do the following:
Checks after operation (with engine stopped)
Have any inspection and maintenance points been forgotten?
Have all inspection and maintenance items been performed correctly?
Have any tools or parts been dropped inside the machine? It is particularly dangerous if parts
are dropped inside the machine and get caught in the lever linkage mechanism.
Are there any leakages of coolant or oil? Have all nuts and bolts been tightened?
