SECTION 4 - LUBRICATION AND MAINTENANCE

Fuel specification

The quality of fuel used is an important factor in

obtaining dependable performance and satisfactory

engine life.

Fuels must be clean, well-refined and non-corrosive

to fuel system parts. Be sure to use fuel of a known

quality from a reputable supplier.

To be sure that a fuel meets the required properties,

enlist the aid of a reputable fuel oil supplier. The

responsibility for clean fuel lies with the fuel supplier

as well as the fuel user

Use Number 2-D fuel in temperatures above -7_C

(20_F). Use of Number 2-D fuel at temperatures

below -7_C (20_F) will cause the fuel to thicken,

which may prevent the engine from running. (If this

happens, contact your dealer.)

Use Number 1-D fuel in temperatures below -7_C

(20_F).
