4.1.5 Drive wheel replacement
Required tools: Flat screwdriver
External circlip pliers
Procedure duration: 5 minutes
A. Remove the Power Pack from the Robomow.
B. Prop the Robomow on a stand so that the drive wheels will not be touching the ground.
C. There are two drive wheels types: smooth wheel and knobby wheel, as illustrated in Figure
4.1.5.1. Make sure to replace the faulty wheel with the same type wheel. Failure to do so will
result in improper operation of the Robomow and might cause damage.
