NOTES:
In freezing temperatures, recharge the batteries after adding distilled water to make sure the water
mixes with the electrolyte properly. Otherwise, the water may freeze and damage the batteries.
The recommended tire pressure is 60 psi for all tires except the foam-fi lled and solid tires. Over or
under infl ation can reduce tire life and adversely affect vehicle handling. It may also lead to sudden tire
failure, which can result in the driver losing control of the vehicle.
A hydrometer is used to determine if a battery is properly charged. It measures the specifi c gravity of
the electrolyte (liquid) in the battery. The electrolyte is about 1260 in specifi c gravity when the battery
is fully charged and about 1100 in specifi c gravity when the battery is fully discharged. 1.
