7. Storage of the Unit
7-1
7.1 Preparation for Long-term Storage
When the unit is to be kept unused in storage for a long time, be sure to follow the preparations
below and put the unit in a dry and less dusty place.
Put the unit in a temporary cabin if it is stored outside. Avoid leaving the unit outside with a sheet
cover directly on the paint for a long time, or this will cause rust to the unit.
Perform the following treatments at least once every three months.
(Procedure)
① Drain existing lubricant from the engine oil pan. Pour new lubricant in the engine to clean its
inside. After running it for a while, drain it again.
② Spread lubricant on moving parts like speed regulator and rod end, beforehand.
③ Completely charge the battery and disconnect grounding wires. Remove the battery from the unit,
if possible, and store it in a dry place. (Charge the battery at least once every month.)
④ Drain coolant and fuel from the unit.
⑤ Seal the engine, air-intake port and other openings like the muffler with a vinyl sheet, packing
tape, etc., to prevent moisture and dust from getting in the unit.
⑥ Be sure to repair any trouble and maintain the unit so that it will be ready for the next
operation.
