After Storage
NOTICE: If the machine was not operated once a
month during storage, contact us or our sales
service agency before using the machine.
Perform the following procedures before using the
machine after long periods of storage.
• Fill the fuel tank with fuel, lubricate all grease
fittings and change the engine oil.
• Remove the cover from the battery or install the
battery if required.
• Check the battery electrolyte level and specific
gravity and then connect the battery positive (+)
and negative (-) cables.
• Drain any water from the fuel tank, hydraulic oil
tank and engine oil. Replace fluids as
necessary.
• Testing the insulation resistance of the electric
motor wiring is required before resuming
operation after long-term storage. Contact us or
our sales service agency to request inspection
procedures and service information.
• Perform all specified pre-start checks before
starting and operating.
COLD TEMPERATURE
PREPARATION
To avoid difficulty when starting during low
temperatures, perform the following procedures.
Engine Oil
Change the engine oil to a low viscosity type. See
the engine operation manual for the specified
viscosity.
Engine Coolant
WARNING! Fire Hazard. Never mix coolant
fluid with methanol, ethanol or propanol.
See “Clean Engine Cooling System” on page 5-44
for coolant replacement intervals and mixing ratio.
Battery
See “Cold Temperature Precautions” on page
5-52.
After Daily Operation
Observe the following to prevent the machine
from not starting or operating due to frozen water
or dirt in or on the machine.
• Remove dirt and water from the machine. Keep
the hydraulic cylinder rod surfaces clean to
prevent seals from being damaged from dirt
mixing with water.
• Park the machine on solid, dry ground. Use
boards as support, if necessary, to park the
machine on.
• Remove the drain plug and drain any water from
the fuel system to prevent freezing.
• Cover the battery or remove the battery from the
machine and keep it in a warm place.
• If the battery electrolyte level is low, refill with
distilled water just before use. Do not refill after
operation, as the water will freeze in the battery.
