PROBLEM
SOLUTION
Engine will not start.
• Check that the blade control knob is in the DOWN,
disengaged position.
• Make sure the spark plug wire is attached.
• If the engine is cold, make sure the throttle is in the
CHOKE position.
• The gas must be fresh and clean. If the gas is old, change it.
Use a fuel stabilizer if you keep gas longer than one month.
• Check the throttle adjustment and travel.
• The spark plug may be dirty or cracked, change it.
• If the spark plug is oily, hold a rag over the plug hole and
crank the engine over a couple of times to blow out any oil in
the cylinder, then wipe off the plug and replace.
• The air filter may be dirty, change it following the procedure
in the engine owner’s manual.
• Check two fuses in the wiring harness and replace if needed.
• Check the ground wire connection, the large green wire
coming from the battery, where it connects to the engine.
• The battery may not be charged. Check the voltage. If it is
low, charge with a 12-volt, 1 to 2-amp trickle charger. If you
do not use your machine for at least 45 minutes at a time, the
battery may need to be periodically charged. See the “Battery
Care” section for instructions.
