Description
This system prevents fuel filter from clogging with fuel wax.
Fuel heater system operates when fuel temperature switch and
oil pressure switch are on.
Fuel temperature switch turns on when fuel temperature
decreases below þ15ÉC (5ÉF). It remains on until fuel tempera-
ture increases to around 0ÉC (32ÉF).
If fuel temperature does not decrease below þ15ÉC (5ÉF), fuel
temperature switch will not turn on even though fuel temperature
is below 0ÉC (32ÉF).

Disassembly
PISTON AND CRANKSHAFT
1. Remove oil filter.
2. Place engine on work stand.
3. Drain coolant and oil.
4. Remove drive belts.
5. Remove cylinder head.
6. Remove oil pan.
7. Remove crankshaft pulley.
8. Remove water pump.
9. Remove timing gear case.
lRemove dust cover with a seal cutter.
lIf the timing case is hard to remove due to liquid gasket,
pry it off with a suitable tool at the cutout section.

ENGINE OVERHAULTD
EM-72

If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
lAvoid prolonged and repeated contact with oils, particularly
used engine oils.
lWear protective clothing, including impervious gloves where
practicable.
lDo not put oily rags in pockets.
lAvoid contaminating clothes, particularly underpants, with oil.
lHeavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
lFirst Aid treatment should be obtained immediately for open
cuts and wounds.
lUse barrier creams, applying them before each work period,
to help the removal of oil from the skin.
lWash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations contain-
ing lanolin replace the natural skin oils which have been
removed.
lDo not use gasoline, kerosine, diesel fuel, gas oil, thinners
or solvents for cleaning skin.
lIf skin disorders develop, obtain medical advice without
delay.
lWhere practicable, degrease components prior to handling.
lWhere there is a risk of eye contact, eye protection should
be worn, for example, chemical goggles or face shields; in
addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating
system must meet the requirements of HM Inspectorate of Pol-
lution for small burners of less than 0.4 MW. If in doubt check
with the appropriate local authority and/or manufacturer of the
approved appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local author-
ity for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or
drains, or into water courses.
The regulations concerning the pollution of the environment
will vary from country to country.
Precautions for Fuel
GASOLINE ENGINE:
Three way catalyst equipped models ... unleaded gasoline of at
least 91 octane (RON)
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Except for the above models ... unleaded or leaded gasoline of
above 88 octane (RON)
Use unleaded fuel if instructed on the fuel filler lid.
