Aftertreatment System and Diesel
Exhaust Fluid
Diesel Exhaust Fluid (DEF) temperatures can reach
65° to 70°C (149.° to 126°F) during normal engine
operation. Stop the engine. Wait for 15 minutes in
order to allow the DEF system to be purged and the
DEF to cool before service or repair is performed.

All fuels, most lubricants, and some coolant mixtures
are flammable.
Flammable fluids that are leaking or spilled onto hot
surfaces or onto electrical components can cause a
fire. Fire may cause personal injury and property
damage.
After the emergency stop button is operated, ensure
that you allow 15 minutes, before the engine covers
are removed.
Determine whether the engine will be operated in an
environment that allows combustible gases to be
drawn into the air inlet system. These gases could
cause the engine to overspeed. Personal injury,
property damage, or engine damage could result.
If the application involves the presence of
combustible gases, consult your Perkins dealer and/
or your Perkins distributor for additional information
about suitable protection devices.
Remove all flammable combustible materials or
conductive materials such as fuel, oil, and debris
from the engine. Do not allow any flammable
combustible materials or conductive materials to
accumulate on the engine.
Store fuels and lubricants in correctly marked
containers away from unauthorized persons. Store
oily rags and any flammable materials in protective
containers. Do not smoke in areas that are used for
storing flammable materials.
Do not expose the engine to any flame.
Exhaust shields (if equipped) protect hot exhaust
components from oil or fuel spray in case of a line, a
tube, or a seal failure. Exhaust shields must be
installed correctly.
Do not weld on lines or tanks that contain flammable
fluids. Do not flame cut lines or tanks that contain
flammable fluid. Clean any such lines or tanks
thoroughly with a nonflammable solvent prior to
welding or flame cutting.
Wiring must be kept in good condition. Ensure that all
electrical wires are correctly installed and securely
attached. Check all electrical wires daily. Repair any
wires that are loose or frayed before you operate the
engine. Clean all electrical connections and tighten
all electrical connections.
Eliminate all wiring that is unattached or
unnecessary. Do not use any wires or cables that are
smaller than the recommended gauge. Do not
bypass any fuses and/or circuit breakers.
Arcing or sparking could cause a fire. Secure
connections, recommended wiring, and correctly
maintained battery cables will help to prevent arcing
or sparking.
Ensure that the engine is stopped. Inspect all lines
and hoses for wear or for deterioration. Ensure that
the hoses are correctly routed. The lines and hoses
must have adequate support and secure clamps.
Oil filters and fuel filters must be installed correctly.
The filter housings must be tightened to the correct
torque. Refer to the Disassembly and Assembly
manual for more information.
