Failure to perform the standstill has resulted in the
diesel particulate filter failure, and regeneration is
no longer possible. Contact an authorized repair
facility to replace the filter.
3.10-3 Perform the Standstill Regeneration
1.
Move the MEWP to an open, well-ventilated area,
away from any flammable material. Park it on a
firm level surface, and fully stow the MEWP.
2.
With the engine running, turn the off/base/
platform switch
7
on the base controls to the
base position.
3.
Activate the standstill regeneration by moving the
standstill switch
8
on the base controls to the
on position. Base functions become inoperative
when the standstill switch is turned on.
4.
On the engine display module
2
press and hold
the middle button
9
(below the regeneration
symbol) for 3 seconds.
WARNING
Do not touch hot engine components.
Touching hot surfaces may cause serious
injury.
5.
The engine display module changes to the
Regeneration Ongoing symbol
10
, the standstill
lamps turn solid, and the engine speed may
change.
6.
Standstill usually takes 35 to 40 minutes. During
this time, the MEWP must not be used.
IMPORTANT
The standstill must be completed fully. If
the process is interrupted, the standstill
request continues.
7.
When the standstill is complete, the Regeneration
Ongoing symbol changes to Regeneration
Complete
11
, the standstill lamps

turn off,
and the engine speed returns to normal.
8.
Move the standstill switch to the off position. The
MEWP may now be used normally.
IMPORTANT
The derate override switch
12
on the front
of the platform control box should only be
used when absolutely necessary to move
the MEWP to park it in a safe location when
the derated engine torque/rpm prevents
adequate torque to drive the MEWP. It
will temporarily (for approximately 30
minutes) restore full engine power and
speed. Be aware that use of the derate
override switch may result in diesel
particulate filter failure.
