12. Certain engine oils are flammable. Some of them are
also dangerous if inhaled. Whenever you use these
agents, follow the manufacturer's instructions on the
product packaging. Ensure that ventilation in the work
place is good. Use a protective mask when spraying.
13. Hot oil can cause burns. Avoid skin contact with hot
oil. Ensure that the lubrication system is not under
pressure before beginning to work on it. Never start or
operate the engine with the oil filler cap removed; oth-
erwise, hot oil could spew out.
14. Never allow an open flame or electric sparks near the
battery or batteries. Never smoke in proximity to the
batteries. The batteries give off hydrogen gas during
charging which when mixed with air can form an explo-
sive gas. This gas is easily ignited and highly volatile.
Incorrect connection of the battery can cause a spark,
which would be sufficient to cause an explosion. Do
not disturb battery connections when starting the en-
gine (spark risk) and do not lean over batteries.
15. Always ensure that the positive and negative battery
leads are correctly installed on the corresponding ter-
minal posts. Incorrect installation can result in serious
damage to electrical equipment.
16. Always use protective goggles when charging and
handling batteries. Battery electrolyte contains sulfu-
ric acid, which is highly corrosive. If battery electrolyte
comes into contact with unprotected skin, wash it off
immediately using plenty of water and soap. If battery
acid comes in contact with the eyes, immediately
flush with copious amounts of water and obtain medi-
cal assistance.
