Proper Tools
Use only tools suited to the task. Using damaged, low quality,
faulty, or makeshift tools could cause personal injury. There is a
danger that pieces from, chisels with crushed heads, or
hammers, may get into your eyes and cause blindness.
Use of Lighting
When checking fuel, oil, battery electrolyte, or window washing
fluid, always use lighting with antiexplosion specifications. If
such lighting equipment is not used, there is a danger of an
explosion.
If work is carried out in dark places without using lighting, it may
lead to injury, so always use proper lighting.
Even if the place is dark, never use a lighter or flame instead of
lighting. There is a danger of fire. There is also danger that the
battery gas may catch fire and cause an explosion.
