Battery
Check the level of the battery fluid and see if the
terminals are tight. Add distilled water if the fluid
level is low.CAUTION:
Do not leave or store the battery on its side.
When inspecting the battery, be sure the
breather hose is routed correctly. If it touches
the frame or exists in such a way as to cause
battery electrolyte or gas to exit onto the
frame, structural and cosmetic damage to the
machine can occur.
