PRE-OPERATION CHECKS
Is Your Engine Ready to Go?
For your safety, and to maximize the service life of your
equipment, take a few minutes before you operate the
engine to check its condition . Take care of any problems you
fine, or have your servicing dealer correct them, before you
operate the engine .
IMPROPERLY MAINTAINING THE ENGINE, OR FAILURE
TO CORRECT A PROBLEM BEFORE OPERATION,CAN
CAUSE A MALFUNCTION IN WHICH YOU COULD BE
SERIOUSLY INJURED OR KILLED. ALWAYS PERFORM A PRE-
OPERATION INSPECTION BEFORE EACH OPERATION AND
CORRECT ANY PROBLEM.
Before beginning your pre-operation checks, be sure the
engine is level and the engine switch is in the OFF position .
Always check the following items before you start the engine:
Check the General Condition of the Engine
1 . Look around and underneath the engine for signs of oil or
gasoline leaks .
2 . Remove any excessive dirt or debris, especially around
the muffler and recoil starter .
3 . Look for signs of damage .
4 . Check that all shields and covers are in place, and all nuts,
bolts and screws are tightened .
Check the Engine
1 . Check the fuel level (see “Refueling” on page 11 ) .
Starting with a full tank will help to eliminate or reduce
operating interruptions for refueling .
2 . Check the engine oil level (see “Engine Oil” on page 12 ) .
Running the engine with a low oil level can cause engine
damage .
The Oil Alert system (applicable types) will automatically
stop the engine before the oil level falls below safe limits .
However, to avoid the inconvenience of an unexpected
shutdown, always check the engine oil level before
startup .
3 . Check the air filter element (see “Air Cleaner” on
page 13 ) . A dirty air filter element will restrict air flow to
the carburetor, reducing engine performance .
4 . Check the equipment powered by this engine .
Review the instructions provided with the equipment
powered by this engine for any precautions and procedures
that should be followed before engine startup .
Check the Throttle Lever
The throttle lever controls the speed of the engine . Push it
forward to increase the engine speed . Pull it back to decrease
the engine speed . The lever is an orange hand control
located on the left side of the backpack .
MPORTANT I
The engine will not start if the throttle lever is all the way back
in the OFF position. Push the lever forward about 1/2" into the
SLOW position to engage it.
