Be Careful of Falling

Lift Engine Carefully
Use slings or wire ropes strong
enough to lift the load considering the
engine weight.To lift the engine, hitch
the proper slings to the lifting hangers
prepared on the engine.To lift the
engine, keep the engine in a well-bal-
anced position, thinking carefully of the engine center
of gravity.
The hangers prepared on the engine are designed for
lifting the weight of engine only.In the case where the
generator, marine gear, and others are installed to the
engine, consideration that the additional weight will not
affect the hangers of the engine.
Keep the angle formed by slings attached to hangers
within 60°.If the angle exceeds this limit, excessive
load may be applied to the hangers and damage the
hangers.If the wire rope contacts the engine directly,
place a cloth or other soft pad to avoid damage to the
engine and sling.
Do not Climb Onto the Engine
Do not climb onto the engine, nor step on any engine
parts on the engine sides.To work on parts located
high on the engine, use a ladder, footing, and others to
prevent from slipping and falling.Climbing onto the
engine may result in engine part damage and your
injury by falling down.
Always Prepare a Stable Footing
When working on the upper part of
the engine and other hard-to-reach
places, use a stable footing.Standing
on an old footstool or parts box may
result in personal injury.Do not put
any unnecessary objects on a footing.
