Glow Plugs
If the glow plug option is enabled in the JLG Control System,
the glow plug and indicator lamp will be energized when the
Power/Emergency Stop switch is pulled on if the ambient air
temperature is less than 50° F (10° C) and the engine coolant
temperature is less than 140° F (60° C). This determination will
occur one second after the Power/Emergency Stop switch has
been pulled on. The lamp and glow plugs will remain ener-
gized for the period of time specified by the setting in the JLG
Control System. Engine start shall be disabled during this
period. On Deutz engines, the glow plugs will continue (post
glow) after the engine has started for three times the machine
digit setting.

to the MAX mark with an approved grade and type of oil
as outlined in the engine manufacturer’s operator’s
manual. Refer to Figure 3-101., Deutz Engine Dipstick.
