loss or damage is noted at the time of delivery, have the
person(s) making delivery note all damage on the freight
bill or affix his signature under the consignor's memo of
loss or damage.

ators weight of more than 900 pounds requires proper
tools, equipment, and qualified personnel to be used in
all phases of handling and unpacking.

ENGINE OIL RECOMMENDATIONS

The unit has been filled with 15W-40 engine oil at the
factory. Use a high-quality detergent oil classified "For
Service CC, SD, SE, SF ." Detergent oils keep the engine
cleaner and reduce carbon deposits. Use oil having the
following SAE viscosity rating, based on the ambient
temperature range anticipated before the next oil
change:
Temperature
Above 80° F (27° C)
32° to 80° F (-1° to 27° C)
Below 32° F (0° C)
CAUTION: Any attempt to crank or start the
engine before it has been properly serviced with
the recommended oil may result in an engine
failure.

NOTE:
Oil Grade (Recommended)
SAE 30W or 15W-40
SAE 20W-20 or 15W-40
SAE 10W or 15W-40
