1G296-8914.book 4 4 ページ２０１２年３月１９日月曜日午前１０時４０分 SAFE OPERATION EXHAUST GASES & FIRE PREVENTION A Engine exhaust fumes can be very harmful if allowing them to accumulate. Be sure to run the engine in a well ventilated place and where there are no people or livestock near the generator. A DO NOT operate the generator in a closed area such as inside houses, warehouses, tunnels, wells, ship holds, tanks, etc. or places without proper ventilation.
PAGE 10
1G296-8914.book 5 ページ２０１２年３月１９日月曜日午前１０時４０分 SAFE OPERATION ESCAPING FLUID A Relieve all pressure in the oil and the cooling systems before any lines, fittings or related items are removed or disconnected. A Be alert for possible pressure when disconnecting any device from a system that utilizes pressure. DO NOT check for pressure leaks with your hand. High pressure oil or fuel can cause serious personal injury.
