Understanding The Diesel-Particulate Filter And Regeneration - Toro Groundsmaster 3300 Series Operator's Manual

•
Lower a folding roll bar temporarily only when
necessary. Do not wear the seat belt when the
roll bar is folded down.
•
Be aware that there is no rollover protection when
a folded roll bar is in the down position.
•
Check the area that you will be mowing and never
fold down a folding roll bar in areas where there
are slopes, drop-offs, or water.
Slope Safety
•
Slopes are a major factor related to loss of control
and rollover accidents, which can result in severe
injury or death. You are responsible for safe slope
operation. Operating the machine on any slope
requires extra caution.
•
Evaluate the site conditions to determine if the
slope is safe for machine operation, including
surveying the site. Always use common sense
and good judgment when performing this survey.
•
Review the slope instructions listed below for
operating the machine on slopes and to determine
whether you can operate the machine in the
conditions on that day and at that site. Changes
in the terrain can result in a change in slope
operation for the machine.
•
Avoid starting, stopping, or turning the machine on
slopes. Avoid making sudden changes in speed or
direction. Make turns slowly and gradually.
•
Do not operate a machine under any conditions
where traction, steering, or stability is in question.
•
Remove or mark obstructions such as ditches,
holes, ruts, bumps, rocks, or other hidden hazards.
Tall grass can hide obstructions. Uneven terrain
could overturn the machine.
•
Be aware that operating the machine on wet
grass, across slopes, or downhill may cause the
machine to lose traction. Loss of traction to the
drive wheels may result in sliding and a loss of
braking and steering.
•
Use extreme caution when operating the machine
near drop-offs, ditches, embankments, water
hazards, or other hazards. The machine could
suddenly roll over if a wheel goes over the edge
or the edge caves in. Establish a safety area
between the machine and any hazard.
•
Identify hazards at the base of the slope.
If there are hazards, mow the slope with a
pedestrian-controlled machine.
•
If possible, keep the cutting unit(s) lowered to the
ground while operating on slopes. Raising the
cutting unit(s) while operating on slopes can cause
the machine to become unstable.
•
Use extreme caution with grass-collection systems
or other attachments. These can change the
stability of the machine and cause a loss of control.
Understanding the
Diesel-Particulate Filter
and Regeneration
The diesel-particulate filter (DPF) removes soot from
the engine exhaust.
The DPF regeneration process uses heat from the
engine exhaust that is increased by the catalyst to
reduce accumulated soot into ash.
To keep the DPF clean, remember the following:
•
Run the engine at full engine speed when possible
to promote DPF self-cleaning.
•
Use the correct engine oil.
•
Minimize the amount of time that you idle the
engine.
•
Use only ultra low sulfur diesel fuel.
Operate and maintain your machine with the function
of the DPF in mind. Engine under load generally
produces adequate exhaust temperature for DPF
regeneration.
Important:
Minimize the amount of time that you
idle the engine or operate the engine at low-engine
speed to help reduce the accumulation of soot in
the DPF.
CAUTION
The exhaust temperature is hot (approximately
600°C (1,112°F) during DPF regeneration. Hot
exhaust gas can harm you or other people.
• Do not operate the engine in an enclosed
area.
• Ensure that there are no flammable
materials around the exhaust system.
• Ensure that the hot exhaust gas does not
contact surfaces that may be damaged by
heat.
• Do not touch a hot exhaust system
component.
• Do not stand near or around the exhaust
pipe of the machine.
