6-4 – JLG Lift – 3121219
Engine
(1) - JLG machines equipped with TIER 3 carbureted model
engine: Kubota DF752-E2
The Altitude Compensation Kit on this TIER 3 engine is set up
from the factory to EPA emission standards for altitudes
below 2800 ft. (700m). Kits for operating at higher altitudes
are available from Kubota.
If operating at higher altitudes without the proper kit installed,
this engine will run with a rich fuel mixture and may therefore
exhibit the following issues:
• Excessive exhaust temperature: This may rapidly or imme-
diately damage the catalyst (if equipped). Engine overheat-
ing may also occur.
• Excessive soot: This will rapidly deteriorate the engine oil,
the valves, and the exhaust ports with carbon deposits. If
enough soot is built up the catalyst (if equipped) may not
function properly.
• Emissions: Kubota cannot guarantee emissions without
the proper Altitude Compensation kit installed.
