WARNING : SUFFOCATION FROM EXHAUST FUME

Do not operatethegeneratorinpoorlyventilated areassuchas indoorsor tunnels,asthe

exhaustgas of the enginecontains substances that areharmfultohuman health.

Do not direct exhaustfumes at pedestriansor buildings.

WARNING : ELECTRIC SHOCK

Do not operatethe equipment withany doorsor covers open.

Always turn all thebreakers OFF, place the Power Switch in the OFFposition andstop the

enginebefore connecting/disconnectingtheloadcabletothe output terminal.

Always turn the Power Switch to the OFF positionandstoptheengine, then close andlock

OPERATION PANELDOOR before checking or maintaining the engine or anyequipment.

Closethe output terminalcoverbeforeoperating.

Do nottouch the generator if thegenerator or casingor yourbodybecomes wet during

operation.

Do nottouchoutputterminals or internalelectric partswhilethe generator is operating.

Ground the everyearthgrounding terminaltothe earthasset out inthemanual.

If evenoneof all is unconnected by mistake or accident, it will bemuch more dangerous for

humanbodythan theNO-RELAYcase, because leaking current inevitably goesthroughthe

body.

Eventhoughalltheearthterminals of the loadshave beengroundedto theearth, thebonnet

groundingterminalshould begroundedtotheearth.

Thereis always a danger of being electrocuted by short-circuit. Be sureto testgenerator’s

insulation resistance periodically.

Grounding should be made after the engine is stopped.

Whenever theEarth leakage relay is activated, you shouldalways repair theleaking place first

of all.

WARNING : INJURY

Closeall doorsandlock them during operation.

Do not openthe check door when thePowerSwitch is in the ON position. It will cause injury

by rotating parts such as cooling fansand fan belt.

Always turn the Power Switch to the OFF positionandstoptheengine, then close andlock

OPERATION PANELDOOR before checking or maintaining the engineor anyequipment.

Usethe lifting hook to lift the machines,and do not liftupbyusing tie downs. Useof such

couldresult inthegeneratorfalling.

Do not liftany additional weight such as fuel tanksor trailers.

No persons shouldever be undera liftedgenerator.

Always be sure to check thatthe breakers on load side andswitches for any equipment using

the generator areatOFFbefore turning thebreaker toON.Also besuretoadvise personnel

on the load side that power will be turnedon or off before operating the breaker.

Do notmodifytheequipment anddo not operatewith parts removed.

CAUTION : EYE/SKIN INJURY

Wearrubberglovesandother protectiveweartoprotecteyes, skin andclothing fromthe

batteryfluid which containsdiluted sulfuricacid. If the batteryfluidcontactseyes or skin, wash

out immediately with asufficient amount of clean water. Besure toreceivemedicaltreatment,

especiallyif thefluid contactstheeyes.

1. Safety Instructions

CAUTION : EXPLOSION

Never use or rechargethebattery if the fluid level is below the minimum level.

Do not createsparks or bring flame near the battery as it generatesflammablegas.

CAUTION : FIRE

Do not carryflammable items(suchas fuel,gas andpaint)or itemsthat arehighlycombustible

nearthe generator as themuffler, exhaustgas andotherpartsbecome extremelyhot.

Position thisgenerator 1 mormore from walls or other hindrances, and on a level surface.

Do not connect thegenerator output to indoor wiring.

This generator usesdieselfuel.Always be sureto stoptheengine andnot bring flamesclose

when inspecting fuelor refueling. Wait until the engine has cooledbeforeperforming such

procedures.

Do not use this equipmentwhen leak is found, and repair theleaking location before

operating.

Always be sure to wipe up anyspilled fuel or oil.

Allowthe generator to coolbefore covering with the protective cover.

Never allowflame tocomecloseto thegenerator.

Always make sure that the Power Switch is OFF position when working on piping.

After working onthepiping,checkthatthereisnofuelleakage.

Absolutely never inspect or performmaintenanceto the equipment near fireor other open

flame.

CAUTION : BURNS

Do nottouch the engineand surrounding components immediatelyafter stopping theengine

as theyarestill extremelyhot.

Do not openthe radiatorcap immediatelyafter stopping the engine, to avoidsustaining burns

from hotvapor.

Hotsteam gushes out from the coolant sub-tank if thegenerator overheats. Donot touchthe

coolant sub-tank.

Always be sure to stop the engine and allowthe engine to cool when performing inspection or

maintenanceof engine oil. Opening theoil level gauge or oil filler cap during operation will

result inhotoilgushing out.

CAUTION : INJURY

Always be sure to use lifting hookswhen lifting up thegenerator, andslowly lift it straight up.

Personnelperforming lifting work must wear protective gearssuch as helmets, safetyshoes

andgloves.

Remove the woodties if using anchors to secure thegenerator.

Position thegenerator on a level stable surface so that it cannot slide or move in any manner.

Before starting operation, always be sure to turn off all switches of equipment using the

generatorand all breakers toOFF.

Do not move the generatorduring operation.

Do not operatethegeneratorif it has beenmodified or anypartshavebeen removed.

Securely fixtheequipment with rope or similar item sothat it cannot move when transporting

by truck or othervehicle.

Check that the surrounding area is safe, before setting toAuto Mode.

Be sure to communicatebetween operators mutuallybefore attempting to set "Auto Mode" to

avoidmechanicaltroubleandincidents.

CAUTION : PROPERTY DAMAGE

Do not usethe equipmentforanyimproper applications.Improper usagecanresultinan

accident or malfunction.

If using this generator for medicalequipment, check beforeuse withthe medicalequipment

manufacturer, doctor, hospital orsimilar entity.

Checkthat the generator output setting,output terminalconnectionandloadpowersource are

consistent.

Cableburnoutcan occur due to generated heat if the load current exceeds the allowable

currentof the cable.

Thevoltage drop betweencables is large if thecable is excessively long or thin, resulting in

decreased input voltagetoequipment using the generator, thereby causing decreased

performance, faultyoperationand malfunction.

When changing the frequency, be suretochangeboth the Frequency Selector Switchand

Controller settings.
