not perform to full capacity and
parts may be damaged.

Use diesel fuels
performance.
Cetane fuel number should be 45 or
greater.
(2) Handling of Fuel Oil
1)Water and dust in the fuel cause
engine failure. When fuel is stored, be
sure that the inside of the storage con-
tainer is clean, and that the fuel is
stored away from dirt or rain water.
2)Keep the fuel container stationery for
several hours to allow any dirt or
water to settle to the bottom. Use a
pump to extract the clear, filtered fuel
from the top of the container for use.
Use the clear filtered fuel from the upper
middle section of the container only, leaving any
contaminated fuel at the bottom.

30mm above the bottom of the tank so
that only clean fuel is used.
