stop, engage parking brake and remove
key, before performing maintenance.
6. With the cap off the radiator, tilt hood closed and
put the seat down. Start the engine as stated in
the Operating Instructions Section. Return the
seat up and hood forward to the open position.
7. Operate engine until the engine thermostat opens
and coolant is circulating through the radiator
core. As air is purged from the engine block and
the coolant level drops, add additional coolant to
the radiator.
