HIGH ALTITUDE OPERATION

At high altitude, the standard carburetor air-fuel mix- ture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above (6,000 feet) 1,800 meters, have a engine dealer perform this carburetor modification.

Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000 feet (300 meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made. Do not operate a modified engine below 6,000 feet.

LIFTING

The Ranger 275 weighs approximately 469 lbs/212 kg. A lift bail is mounted to the machine frame and should always be used when lifting the machine.

ADDITIONAL SAFETY PRECAUTIONS

WARNING

FALLING EQUIPMENT can cause injury.

●Do not lift this machine using lift bale if it is equipped with a heavy accessory such as trailer or gas cylinder.

●Lift only with equipment of adequate lifting capacity.

●Be sure machine is stable when lifting.

PRE-OPERATION ENGINE SERVICE

CAUTION

READ and UNDERSTAND the engine operating and maintenance instructions supplied with this machine.

------------------------------------------------------------------------

WARNING

•Keep hands way from the engine muffler or HOT engine parts.

•Stop the engine when fueling.

•Do not smoke when fueling.

•Do not overfill the fuel tank.

•Wipe up spilled fuel and allow the fumes to clear before starting the engine.

•Keep sparks and flame away from the fuel tank.

------------------------------------------------------------------------

OIL

The Ranger 275 is shipped with the engine filled with SAE 10W-30 oil. CHECK THE OIL LEVEL BEFORE YOU START THE ENGINE. If it is not full, add enough oil to fill it to the full mark.

For more information on oil viscosity and service con- ditions, see the MAINTENANCE section of this manu- al and the engine Operator’s Manual.
