Tool applications safety
Apply the proper tool for each job. With the knowledge
of correct tool use and knowing the limitations of tools,
along with some common sense, many accidents can be
prevented.
Special service tools are available for specific jobs and
should be used when recommended. The use of these
tools will save time and prevent damage to parts.
Battery safety precautions
Batteries
When servicing batteries, always wear protecting
clothing and glasses.
1
The electrolyte in batteries is a sulphuric acid
solution which is fatal if it hits your eyes, and which
can cause burns if it contacts your skin. Therefore,
be careful when handling batteries, e.g. when
checking the charge condition.
2 Install a sign prohibiting fire, open flame and
smoking at the post where batteries are being
charged.
3 When batteries are being charged, an explosive gas
mixture forms in the cells and might escape through
the vent holes in the plugs.
Thus an explosive atmosphere may form around the
battery if ventilation is poor, and can remain in and
around the battery for several hours after it has been
charged. Therefore:
- never smoke near batteries being, or having
recently been, charged,
- never break live circuits at battery terminals,
because a spark usually occurs.
4 When connecting an auxiliary battery (AB) in
parallel to the unit battery (CB) with booster cables:
connect the + pole of AB to the + pole of CB, then
connect the - pole of CB to the mass of the unit.
Disconnect in the reverse order.
