Fuel Recommendations

IMPORTANT: DO NOT use home heating oil or bio-
diesel fuel.
Use No. 2D diesel fuel when temperatures are above
freezing. When temperatures are below freezing, blend
No. 1D diesel fuel and No. 2D diesel fuel together (50/50
ratio) to adjust for the ambient temperature.
Diesel fuel must also meet the following requirements:
Sulfur content of 15 parts per million (ppm)
•
maximum
Minimum Cetane index of 40.
•
NOTE: Low ambient temperatures as well as operation
at high altitudes may require the use of fuels with higher
Cetane ratings.

Engine Oil Recommendations

To maintain the product warranty, the engine oil should
be serviced in accordance with the recommendations of
this manual. Refer to Figure
CAUTION
Engine damage. Verify proper type and quantity of
engine oil prior to starting engine. Failure to do so
could result in engine damage.

Coolant Recommendations

CAUTION
Engine damage. Use approved coolant only.
Failure to do so could result in equipment damage.
Improper coolant can damage the engine cooling system.
Use demineralized water or distilled water for best results.
Hard water causes scale deposits, which reduces cooling
efficiency and raises internal temperatures, possibly leading
to engine damage. Use an anti-corrosive to prevent rot in
summer and anti-freeze to prevent freezing in winter.

Standard Units

The use of a long-life ethylene glycol coolant (LLC) at
60% concentrate. (40% water) is recommended. When
operating in ambient temperatures above 0°F (-18°C),
use a 50/50 ratio.

Cold Climate / Arctic Package Units

The cooling system is pre-filled with extended-life
ethylene glycol coolant blend (60/40) rated for heavy duty
use to a maximum freezing point of –62°F (–52°C).

Prestart Checklist

Before starting the unit, all items in the prestart checklist
must be completed. This checklist applies to both manual
