Chapter 1 BASIC SAFETY PRECAUTIONS
Stay Clear of All Rotating and Moving Parts
Install Protective Covers
Around Rotating Parts
Make sure the protective covers of
the engine are correctly installed.
Repair any damaged or loose covers.
Never remove the covers such as
damper cover, camshaft cover, or
rocker cover that enclose the revolving parts during
operation.
When the engine is coupled to driven equipment, be
sure to provide protective covers over the parts such
as the connecting belts and couplings that are
exposed.
Never remove protective covers.
Check Work Area for Safety
Before starting the engine, make sure no one is near
the engine and tools are not left on or near the engine.
Verbally notify persons within the immediate area
when starting the engine.
When the starter device is posted with a sign that pro-
hibits startup operation, do not operate the engine.
Stay Clear of Moving Parts
While Engine is Running
Stay away from rotating or sliding
parts of the engine while the engine is
running. Put objects, which might be
easily caught by rotating parts, away
from rotating parts.
If any part of the clothing or outfitting is caught by a
rotating part, serious bodily injuries could result.
Lockout and Tagout
Be sure to lockout and tagout before starting inspec-
tion and maintenance.
Lockout and tagout are effective methods of cutting off
machines and equipment from energy sources.
To accomplish the lockout/tagout, remove the starter
switch key, set the battery switch to OFF and attach a
"Do Not Run" or similar caution tag to the starter
switch.
The starter switch key must be kept by the person
who performs inspection and maintenance during the
work.
In the case of pneumatic starting type, close the main
valve of the air tank and post a tag saying "Do Not
Open the Valve" or the like.
Keep Engine Stopped During
Servicing
Be sure to stop the engine before proceeding to
inspection and service procedure. Never attempt to
make adjustments on the engine parts while the
engine is running.
Rotating parts such as belt can entangle your body
and cause serious injuries.
Always Restore Engine Turn-
ing Tools After Use
Be sure to remove all turning tools used during main-
tenance and inspection work. Remember also that the
manual turning gear shaft must be pulled out before
starting the engine.
Starting the engine with the turning tools inserted or
with the turning gear in engagement can lead to not
only engine damage but also personal injuries.
