8. Storage of the Unit
8-1
8.1 Preparation for Long-term Storage
When the unit is to be unused in storage for a long time, be sure to follow the preparations below
and store the unit in a dry and clean area.
(1) Temporarily cover the unit 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.
(2) Run the unit at least 5 minutes once every week to circulate oil to each part of the unit.
(3) When the unit is stored in a place where it is difficult to run it once a week, be sure to follow
procedures below:
(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 each moving part.
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
Discharge coolant and fuel from the unit.
⑤
Seal air-intake port of engine 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 breakdown and maintain the unit so that it will be ready for the next
operation.
Replenish the coolant, engine oil and fuel and run the unit at least once every 3 months,
even in long term storage.
