Removing the Machine from Storage
d
WARNING: In case lubrication operation is
unavoidably performed indoors, open windows and
doors to maintain good air ventilation to prevent
asphyxiation. Lubricant property will deteriorate
even if the machine is kept stored. Check all lubricants
before operating the machine after being stored.
Apply the parking brake while storing.
IMPORTANT:
 Lubricants will deteriorate during storage of the
machine.
 Thoroughly check lubricants and adequately
perform lubrication operation before resuming
operation of the machine. Avoid quick operation.
Failure to do so may cause damage to the engine,
hydraulic equipment, transmission, axle, etc. due to
insufficient lubrication.
 If lubrication running is not performed for more
than three months, start the engine by following the
procedure below.
1. Crank the engine without injection input
(operate by starter motor) for three seconds
and stop 10 seconds. Repeat this process three
times.
2. Start the engine. Run the engine at slow
idle speed for three minutes. Then carry out
lubrication running for cylinders.
If you suddenly started the engine or operated
the cylinders without following the procedure
above, it may cause damage to the machine such
as engine seizure.
