Storage And Idle Machine Preparation; Short Term Idle Periods - Komatsu 930E-2 Shop Manual

STORAGE AND IDLE MACHINE PREPARATION

There may be periods when it is necessary for a ma-
chine to be idle for an extended period of time. Properly
prepared, a stored machine may promptly and safely
be put back into operational service. Improper prepa-
ration, or complete lack of preparation, can make the
job of getting the vehicle back to operating status
difficult.
The following information outlines the essential proper
steps for preparing a unit for extended storage, and the
necessary steps to bring it back to operational status -
these are the ideals. Additional information is given to
help restore those machines which were not put into
storage, merely shut down and left idle for a long period
of time.
There will be periods when a vehicle may be idle from
30-60 days, but must be ready for use at all times.
The most effective handling of this type situation is to
follow the procedure given below to prevent any dete-
rioration from beginning.
1. Keep the vehicle fully serviced.
2. On a weekly schedule, perform a visual check of
the vehicle, start and run the engine until it is up
to operating temperature. Move the vehicle
around the yard for a few minutes to insure that
all internal gears and bearings are freshly lubri-
cated.
3. Operate all hydraulic functions through complete
range to insure that cylinder rams and all seals are
fully lubricated.

Much of this material is of a general nature since the
environment, where the machine has been standing
idle, will play a big part in its overall condition. Hot,
humid climate will affect vehicle components much
differently than the dry desert atmosphere or a cold
arctic environment. These climatic aspects must be
considered, and appropriate actions taken when re-
storing a long term idle vehicle.
These instructions are not intended to be all inclusive,
but are furnished to provide the minimum guide lines.
The final aim should always be to provide the operator
with a safe, fully productive vehicle, that he can rely on.
