Information:
Fire Extinguisher
Have a fire extinguisher available and know how to use it. Inspect and have it serviced as recommended on its instruction plate.Crushing or Cutting Prevention
Support equipment and attachments properly when working beneath them.Never attempt adjustments while the engine is running unless otherwise specified in this manual.Stay clear of all rotating and moving parts. Guards should be in place whenever maintenance is not being performed.Keep objects away from moving fan blades. They will throw or cut any object or tool that falls or is pushed into them.Wear protective glasses when striking objects to avoid injury to your eyes.Chips or other debris can fly off objects when struck. Make sure no one can be injured by flying debris before striking any object.Mounting and Dismounting
Do not climb on, or jump off the engine or stand on components which cannot support your weight. Use an adequate ladder. Always use steps and handholds when mounting and dismounting.Clean steps, handholds and areas of the engine you will be working on or around.Before Starting the Engine
Inspect engine for potential hazards.Be sure all protective guards and covers are installed if an engine must be started to make adjustments or checks. To help prevent an accident caused by parts in rotation, work carefully around them.Do not disable or bypass automatic shutoff circuits. They are provided to prevent personal injury and engine damage.Never start an engine with the governor linkage disconnected.Make provisions for shutting off the air or fuel supply to stop the engine if there is an overspeed on start-up after performing repair or maintenance to the engine.See the Maintenance section of this manual for adjustment, or the Service Manual for repairs.Engine Starting
DO NOT start the engine or move any of the controls if there is a warning tag attached to the controls. Check with the person who attached the tag before starting.Make sure no one is working on, or close to the engine or engine driven components before starting it. Always make an inspection of the engine before and after starting.Start the engine only from the operator's station. Never short across the starter terminals or the batteries as this could bypass the engine neutral-start system as well as damage the electrical system.Always start the engine according to the required Engine Starting procedure described in this manual to prevent major engine component damage and personal injury.Make sure the engine is equipped with a lighting system as required by conditions.Make sure all lights are working properly.Check the jacket water and oil temperature gauges frequently during the operation of jacket water and/or lube oil heaters to ensure proper operation.Diesel engine exhaust contains products of combustion which may be harmful to your health. Always start and operate the engine in a well-ventilated area and, if in an enclosed area, vent the exhaust to the outside.Ether
Ether is poisonous and flammable.Inhaling ether vapors or repeated contact of ether with skin can cause personal injury.Do not smoke while changing ether cylinders.Use ether only in well ventilated areas.Use ether with care to avoid
