Start engine.
After engine stalls,crank
it
two orthree times to
release allfuel pressure.
4. Turn ignition switchoffand reconnect fuelpump
fuse.

Fuel Pressure Check
• When reconnecting fuelline, always usenew clamps.
• Make surethatclamp screwdoesnotcontact adjacent
parts.
• Use atorque drivertotighten clamps.
• Use Pressure Gaugetocheck fuelpressure.
• Donot perform fuelpressure checkwithsystem operating.
Fuel pressure gaugemayindicate falsereadings.

1. Release fuelpressure tozero.
2. Disconnect fuelhose between fuelfilter andfuel tube
(engine side).
3. Install pressure gaugebetween fuelfilter andfuel tube.
4. Start engine andcheck forfuel leakage.
5. Read theindication offuel pressure gauge.

Preparation ofcold start device

1. Turn coldstart device linkage clockwise.
2. Set asuitable block[Thickness: about15mm (0.59 in)]
between coldstart device plunger andlinkage rod.
3. Turn crankshaft 2turns clockwise toset the device tonor-
mal position.

Checking
1. Set NO.1 piston atTDC onitscompression stroke.
TDC: Without paintedmark
2. Remove injection tubesandairbleeder onthe back ofinjec-
tion pump.
3. Set dial gauge soitsindicator pointstosomewhere between
1.0 and 2.0mm (0.039 and0.079 in)onthe scale.
4. Turn crankshaft 1turn clockwise andcheck thatdialgauge
indicates thesame value again.
5. Turn crankshaft counterclockwise about20to25 degrees,
then setdial gauge indicator to0mm (0in).
6. Turn crankshaft clockwiseandsetthe pump timing markto

• When repeating thechecking, startwithstep 5.

Adjusting
1. Ifplunger liftisnot within thespecified value,adjust by
turning injection pump.
• Ifindication issmaller thanthespecified value,turnpump

PRECAUTIONS
Engine Oils(ConI' d)

• Wash withsoap andwater toensure alloil isremoved (skin
cleansers andnailbrushes willhelp). Preparations contain-
ing lanolin replace thenatural skinoilswhich havebeen
removed.
• Donot use gasoline, kerosine, dieselfuel,gasoil,thinners
or solvents forcleaning skin.

• If
skin disorders develop,obtainmedical advicewithout
delay.
• Where practicable, degreasecomponents priortohandling.
• Where thereisarisk ofeye contact, eyeprotection should
be worn, forexample, chemicalgogglesorface shields; in
addition aneye wash facility should beprovided.

ENVIRONMENTAL PROTECTIONPRECAUTIONS

Burning usedengine oilinsmall space heaters orboilers can
be recommended onlyforunits ofapproved design.Theheat-
ing system mustmeettherequirements ofHM Inspectorate of
Pollution forsmall burners ofless than 0.4MW. Ifin doubt check
with theappropriate localauthority and/ormanufacturer ofthe
approved appliance.
Dispose ofused oiland used oilfilters through authorized
waste disposal contractors tolicensed wastedisposal sites,or
to the waste oilreclamation trade.Ifin doubt, contact thelocal
authority foradvice ondisposal facilities.
It is illegal topour used oilontothe ground, downsewers or
drains, orinto water courses.
The regulations concerningthepollution ofthe environment
will vary between regions.

Precautions forFuel
GASOLINE ENGINE:

For Europe

Unleaded gasolineofat least 95octane (RON)
CAUTION: Do not use leaded gasoline. Usingleaded gasoline willdamage
the catalytic converter.

Except Europe

Unleaded gasolineofat least 91octane (RON)

DIESEL ENGINE*:

Diesel fuelofat least 50cetane
If two types ofdiesel fuelareavailable, usesummer or
winter fuelproperly according tothe following temperature
conditions.
• Above -rc(20°F) Summer typediesel fuel.
• Below
-rc
(20°F) Wintertypediesel fuel.
CAUTION:
• Donot use home heating oil,gasoline, orother alternate
fuels inyour diesel engine. Theuseofthose cancause
engine damage.
• Donot use summer fuelattemperature below_7°C(20°F).
The cold temperatures willcause waxtoform inthe fuel. As
a result, itmay prevent theengine fromrunning smoothly.
• Donot add gasoline orother alternate fuelstodiesel fuel.
