The
undersides ofthe floor andwheelhouse areundercoated toprevent rust,vibration, noiseandstone
chipping.
Therefore, whensuchapanel isreplaced orrepaired, applyundercoating tothat part. Useanundercoating with
the following properties: rustpreventive, soundproof, vibration-proof, shock-resistant, adhesive,anddurable.
Precautions inundercoating
1. Donot apply undercoating toany place unless specified (suchasthe areas above themuffler andcatalytic
converter whicharesubjected toheat).
2. Donot undercoat theexhaust pipe,other partswhich become hot,androtary parts.
3. Apply bitumen waxafter applying undercoating.

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.
