• Keep various components such as tanks, engine,
hydraulics clean.
Modern exhaust aftertreatment components are re-
quired to operate at very high temperatures to ensure
proper emissions reductions. Equipment OEM’s are
required to include components such as insulation,
exhaust blankets, etc. to maintain these temperatures.
These additional insulation components create one
more opportunity to gather contamination.
Any component, especially those directly exposed to
high temperatures, must be checked for contamina-
tion, cleaned regularly, and replaced if regular cleaning
does not eliminate the contamination. Weekly visual
inspections may be required in environments with high
levels of debris or contamination, but close inspections
are required during normal Preventative Maintenance
(PM) intervals to ensure engine and exhaust insulation
are not soaked with hydraulic oils or other ammable
liquids. If these parts are found to be heavily contami-
nated, the parts must be replaced, not simply cleaned
with water.
Taylor has made updates to the exhaust insulation
used on the right side of the machine leading to the
mufer/aftertreatment system. The horizontal portion
of the insulation which is routed below the engine has
been removed, making damage to the insulation from
encountering road debris less likely and preventing ac-
cumulation of spilled uids on the horizontal portion of
the exhaust system. An illustration of the current and
modied insulation is shown below (See Figure Nos. 1
and 2).
If upon inspection, damage to the insulation or accumu-
lation of uids within the insulation is noted, the insu-
lation must be replaced. Contact your local servicing
Taylor Sudden Service dealer for the appropriate parts.
Lift trucks operate in a wide range of applications.
These applications involve some of the harshest
environments for mobile equipment which cause
dirt, debris, contamination and buildup of oils and
grease around the engine, axle, exhaust and other
components. A strict maintenance routine is vital
for many reasons including the prevention of haz-
ards involving high temperatures and the potential
for res.
:ADeath, serious injury and prop-
erty damage can occur from mobile equipment
res. Adhere to a strict maintenance routine
to keep debris and contamination away from
engine and exhaust components which can
operate at high temperatures.
Strict maintenance routines have always been
required with industrial mobile equipment. Howev-
er, engines equipped with exhaust aftertreatment
components which comply with the newest EPA
requirements for exhaust emissions operate at
much higher temperatures than past engines.
Users must revisit their internal procedures to
ensure precautions are taken with newer equip-
ment to keep exhaust components clean of debris
or contamination. Always refer to current operator
guides, safety literature, and maintenance man-
uals for information concerning re hazards and
maintenance procedures for your equipment. In
environments which have increased amounts of
debris, such as wood processing, grain process-
ing, ammable uids, etc., increased cleaning
intervals are required.
Unrepaired hydraulic leaks, spills of ammable
uids, and overlled uid reservoirs can all be ad-
ditional sources of fuel for equipment res. Good
cleaning and maintenance is a must! As stated in
the maintenance manual:
• Steam clean / wash the truck prior to performing
maintenance.
• Keep vehicle clean and free of grease, oil or dirt
build up that can act as fuel for a re by regular
thorough cleaning.
