Safety Instructions
IMPORTANT INFORMATION:
Avoid sparking and its consequences by:
Wearing protective glasses.
Make sure that the fuel cap is fitted and that no
flammable liquids are stored in an open container.
Do not work on the starter motor circuit in the vicinity of
spilt fuel.
Disconnect the battery's power connection cable (usually
the black negative cable) first and connect it last.
Exercise care with tools so that short circuiting does
not occur.
Do not short circuit across the starter relay's
connections to run the starter motor.
• Be especially careful when handling battery acid.
Acid on the skin can cause serious corrosive
injuries. In the event of spillage on the skin wash
immediately with water.
