Know and abide by the basic safety rules.
Read and understand the Operator's Manual before entering the cab.
Follow directions on all placards. Know what they mean and follow their instructions.
Operators must be thoroughly familiar with safe crane operating practices and have a complete understanding of
all operation and maintenance instructions provided. Operators should be physically fit and thoroughly trained, with
related experience, not be easily excitable, not be subject to epileptic seizures, and not be using any drug that could
impair physical, visual, or mental reactions or capabilities.
Wear the proper clothing for the job.
Wear personnel protective equipment as required by local or job
regulations.
Inspect the crane every day (before the start of each shift). Ensure that routine maintenance and lubrication are
being dutifully performed. Do not operate a damaged or poorly maintained crane. You risk lives when operating faulty
machinery, including your own.

Diesel Fuel Recommendations/Specifications
WARNING
Do not mix gasoline or alcohol with diesel fuel. This mixture can cause an explosion.
NOTE
Any adjustment to compensate for reduced performance with a fuel system using alternate
fuel is not warrantable. Also, wear on any midrange fuel pump component attributed to the
lack of lubrication in the fuel is not a warrantable repair.
Use ASTM No. 2-D fuel with a minimum Cetane number of 40. No. 2 diesel fuel gives the best economy and
performance under most operating conditions. Fuels with Cetane numbers higher than 40 may be needed in high
altitudes or extremely low ambient temperatures to prevent misfires and excessive smoke. At operating temperatures
below 32 (0 ), use a blend of No. 1-D and No. 2-D fuels, also known as "winterized" No. 2-D.
F
C
Use low sulfur content fuel having a cloud point that is at least 10 degrees below the lowest expected fuel
temperature. Cloud point is the temperature at which crystals begin to form in diesel fuel. The viscosity of the fuel must
be kept above 1.3 centistokes to provide adequate fuel system lubrication at 104 (40 ).

C
Acceptable Alternate Fuel Types:
No. 1-D Diesel and No. 2 Fuel Oil
Acceptable Alternate Fuel Types (if 5% new lube oil
No. 1-K Kerosene, No. 2-K Kerosene,
is blended with these fuels to increase the lubricity):
Jet-A, Jet A-1, JP-5, and JP-8
Unacceptable Fuel Types:
Jet-B, JP-4, and Cite
