HM126 Operator’s Manual
The engine comes with a brass oil drain extension to make oil changes easier. When removing
the drain plug, use a wrench to hold the brass extension stationary while a second wrench
loosens the plug. Failure to follow this procedure could damage the threads in the aluminum
engine block and void the warranty.
Repeat the process in reverse to re-install the drain plug. Remember to hold the brass
extension stationary with a second wrench when tightening the plug.
