3.14 SPARK ARRESTER CLEANING INSTRUCTIONS
1. Remove cleanout plug in bottom of spark arrester (muf-
fler).
2. Without causing deformation (or any type of damage to
spark arrester) repeatedly tap on arrester near cleanout
plug. This may be enough to begin spark trap drainage.
3. An industrial vacuum cleaner can do a complete job at
this point.
a. Or, IN A SAFE AREA, start engine. Alternate between
low idle and high idle for two to three minutes.
b. Or, operate engine as required by application for
two to three minutes.
4. Install cleanout plug.
3.15 GLOW PLUGS
If glow plug option is enabled in the JLG Control System, glow
plug and indicator lamp will be energized when Power/Emer-
gency Stop switch is pulled on if ambient air temperature is
less than 50° F (10° C) and engine coolant temperature is less
than 140° F (60° C).
This determination occurs one second after the Power/Emer-
gency Stop switch has been pulled on. Lamp and glow plugs
remain energized for period of time specified by setting in the
JLG Control System. Engine start is disabled during this period.
On Deutz engines, glow plugs continue (post glow) after
engine has started three times the machine digit setting.
