25.1

BEFORE STORAGE

When putting the lift truck in storage for a long time, do as follows:
• Wash, clean and dry every part, then house the lift truck in a dry building. Never leave it outdoors.
NOTICE
In case it must be left outdoors, park the lift truck on flat, dry ground, and cover it securely with a water-
proof sheet.
• Completely fill the fuel tank, grease all parts, and change the oil before storage.
• Apply a thin coat of grease to the exposed surface of the piston rods of the hydraulic cylinders.
• Disconnect the negative terminal of the battery and cover the battery, or remove the battery from the lift truck
and store it separately.
• If the temperature drops below 32° (0°C), add antifreeze to the cooling water.
• LPG engine lift trucks: Turn off fuel service valve (clockwise) and let engine run out of fuel. Then turn ignition
switch of the OFF position. Remove the LPG tank from the truck and store properly in secured area.

DURING STORAGE

If it is necessary to carry out the rust prevention operation while the lift truck is indoors, open the
doors and windows to improve ventilation and prevent gas poisoning.
25.2.1 RUST PREVENTION OPERATION
Operate the engine and move the lift truck for a short distance once a month so that a new film of oil will be coated
over the lubricated surfaces. This prevents loss of the oil film over the long period of storage.
Before operating the work equipment, wipe off the coat of grease from the hydraulic cylinders.
25.2.2 CHARGE BATTERY
Even if the battery is not used, it will naturally discharge if left for a long period. Always charge the battery once a
month.
25.3

AFTER STORAGE

NOTICE
If the lift truck has been stored for a long period without being covered or without carrying out the monthly
rust prevention operation, do as follows before using it.
• Remove the drain plugs from the oil pan and each case, and drain out the water.
• Wipe off the grease from the hydraulic cylinder rods.
• Remove the cylinder head cover, add oil to the valves and rocker arms, and check the operation of the valves.
• After starting the engine, carry out the warming-up operation until the engine oil pressure warning lamp goes
out in order to settle all the parts thoroughly.
