MAINTENANCE
general
Clean the installation surfaces
When installing and removing parts, be sure
that the surfaces of contact of the parts are
clean. If the sealing grooves of the surface of
contact are damaged, consult your sales or
service dealer for repair or release.
Seals and split pins
• Be sure to replace all seals and cotter pins
with new ones.
• When installing, be careful not to damage
or twist the seal.
Sealing tape
• When wrapping the plug with sealing tape,
remove any old sealing tape from the
threads and clean the threads.
• Wrap the thread tight with seal tape
starting 1 or 2 threads away from the
thread end.
Disposing of wastes
• Always collect oil that is drained from the
machine in containers. Improperly
disposed waste oil can cause
environmental harm.
• Follow appropriate laws and regulations
when disposing of harmful objects such as
oil, fuel, cooling water, coolant, filters and
batteries.
Check after maintenance
• Gradually increase the engine speed from a
low idle to maximum speed and check that
there is no oil or water leaking from
serviced parts.
• Operate each control lever and check that
the machine is operating properly.
Cautions on handling of battery wiring
• Disconnect the wiring from the both
terminals (+ and –) on the battery before
working on the electrical system or doing
electric welding.
Always disconnect it from the earth side (–).
When connecting, connect the earth side
last.
• Do not disconnect the battery wiring while
the engine is moving. Otherwise, the
electric circuits of the rotary converter or
others may be damaged.
