Section 4 - ADJUSTMENTS & REPAIR 

 

WARNING 

DO NOT attempt any adjustments, maintenance or 
service with the engine or blade running. STOP 
blade. STOP engine. Set brake. Remove key. 
Remove spark plug wire from spark plug and secure 
wire away from spark plug. Engine and components 
can be extremely hot. Avoid burns by allowing 
engine and components sufficient time to cool. 
Never attempt to service or charge the battery while it 
is installed on the SCRAMBLER. Shield the positive 
terminal with terminal cover located on battery 
harness. This prevents metal from touching the 
positive terminal, which could cause sparks. Cables 
must be connected to battery terminals in the proper 
position as shown. If battery is removed, DO NOT 
operate engine without insulating Po battery 
cable terminal with electrical tape, or sparking from 
the battery cables can result.
