ELECTRONIC TIPS FOR THE SMALL ENGINE TECHNICAN
A service person who has spent many years working on gas mowers may feel uneasy when working on
the new generation of electric mower. If this sounds like you, fear not, you're not alone. This section is
for you.
Keep in mind you were born with the most powerful trouble shooting tools:
Eyes: LOOK for signs of wear, deformation, disconnection, pinched wires,
charger LED patterns
Ears: LISTEN for beeps (error codes), clicks (relay), squeals (bearings)...
Nose: SMELL overheated components, tranny oil leaks...
Touch: FEEL (carefully) if components are too hot or not warm at all, vibration
Mouth: ASK for help or a second opinion if something is in question. A second set of eyes and
ears can do wonders.
