MAINTENANCE
Read all of this manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notices, Cautions, Warnings, and Dangers.

HARDWARE

Generally, three classes of standard hardware and three classes of metric hardware are used in the vehicle. Grade 5
hardware can be identified by the three marks on the hexagonal head; grade 8 hardware is identified by six marks on
the head; grade 2 hardware is unmarked. The class specifiction is marked on metric hardware.
Periodically, the vehicle should be inspected for loose fasteners. Fasteners should be tightened with care and in accor-
dance with the Torque Specifications table or as specified in the Repair and Service Manual for this vehicle.
Unless otherwise noted in text, tighten all hardware in accordance with this chart.
This chart specifies 'lubricated' torque figures. Fasteners that are plated or lubricated when
installed are considered 'wet' and require approximately 80% of the torque required for 'dry' fasteners.

BATTERY CHARGING AND MAINTENANCE

Safety

Always observe the following warnings when working on or near batteries.
To prevent battery explosion that could result in severe personal injury or death, keep all smok-
ing materials, open flames or sparks away from the batteries.
Hydrogen gas is formed when charging batteries. Do not charge batteries without adequate ven-
tilation. A 4% concentration of hydrogen gas is explosive.
Be sure that the key switch is off and all electrical accessories are turned off before starting work
Never disconnect a circuit under load at a battery terminal.
