SAFETY CAUTIONS
0 - 3
Warning Risk of entanglement into the machine
●
Keep guards on the rotating parts
Ensure that all guards are correctly
installed over the rotating parts of
the engine. Damaged or loose
guards should be repaired.
Never attempt to remove the
camshaft cover, rocker cover or any other guards
form rotating parts while the engine is running.
Never leave exposed the drive belts and related
couplers for auxiliaries and radiator. They should
also be covered with guards.
Never remove these guards.
●
Ensure safety in the surrounding area
when starting the engine
Before starting the engine, ensure that no one is near
the electric power generator and that no tools or
foreign matter are left behind. Shout to people
around you so that they will know you are starting
the engine.
Never start the engine if a “Do not start” tag or any
other similar message is posted on the starter switch,
etc.
●
Keep away from rotating parts while
the engine is running
Never stand near the rotating parts
while the engine is running.
Do not place objects near the rotating
parts that are likely to be caught by
these parts.
Should any part of human body (or tool) is caught by
the rotating parts, dismemberment or other bodily
injury will result.
●
Lockout/tagout
Perform lockout/tagout before carrying out any
inspection/service.
Lockout/tagout is an ideal way of disconnecting the
machine/equipment from the power source.
To lockout/tagout, remove the starter switch key,
place the battery switch in the “OFF” position, and
post a “Do not start” tag or other similar message on
the starter switch.
The starter switch key should then be carried by the
person who is going to perform inspection/service.
If an air start system is used, close the air tank source
valve and post a “Do not open” tag or other similar
message.
●
Always stop the engine before any
inspection/service
Always stop the engine before performing any
inspection/service. Never attempt to adjust belt
tension while the engine is running. Otherwise, the
operator runs a great risk of becoming entangled into
the rotating parts and seriously injured.
●
Remove the turning gear after use
Be sure to remove the turning gear after use. Never
start the engine with the turning gear still installed or
“engaged.” Otherwise, the engine will break and
possibly someone may become injured.
