Be Careful Of Exhaust Fume Poisoning; Operate Engine In A Well-Ventilated Area; Be Careful Of Falling Down; Lift Engine Carefully - Mitsubishi Heavy Industries L-Series Operation & Maintenance Manual

Be careful of exhaust
fume poisoning
Operate engine in a well-venti-
lated area
If the engine is installed in an
enclosed area, and the exhaust gas
is ducted outside, ensure that there is
no exhaust gas leakage from duct
joints.
When using the engine as portable generator set, do
not run it in doors such as a warehouse or tunnel, or in
an poorly-ventilated area near the shielding. When
running it indoors by necessity, discharge the exhaust
gas to outside and thoroughly ventilate the room.
Make sure the exhaust gas is not discharged directly
to surrounding buildings, plants or living passersby.
Exhaust gas from the engine contains carbon monox-
ide and other harmful substances. Operating the
engine in an poorly-ventilated area can produce gas
poisoning.
Chapter 1 BASIC SAFETY PRECAUTIONS

Be careful of falling down

Lift engine carefully

To lift the engine, use slings capable
of supporting the weight of the
engine.
Attach the wire rope to the hangers
provided on the engine using a cor-
rect sling.
During lifting process, keep the engine in a well-bal-
anced position by taking the center of gravity of the
engine into consideration.
Keep the angle formed by slings attached to hangers
within 60°. If the angle exceeds this limit, excessive
load could be imposed on the hangers and this could
damage the hangers and result in a serious accident.
If the wire rope contacts the engine directly, place a
cloth or other soft padding to avoid damage to the
engine and wire rope.

Do not climb onto the engine

Do not climb onto the engine, nor step on any engine
parts located on the lateral sides.
To work on parts located on the upper section of
engine, use a ladder, stool, etc., that was firmly
secured.
Climbing on the engine may not only damage engine
parts but also cause falling down from the engine and
result in personal injuries.

Always prepare stable scaffold

When working on the upper part of
the engine and other hard-to-reach
places, use a stable work platform.
Standing on a decrepit stool or parts
box may result in personal injury.
Do not place any unnecessary objects on a work plat-
form.
