18 Disconnect –battery-clamp before starting electrical servicing or welding (evt. turn battery-switch in
“off” position).
19 When repair has been completed, the machine shall be barred over at least one revolution for
reciprocating machines, several revolutions for rotary ones to ensure that there is no mechanical
interference within the machine or driver. Check the direction of rotation of electric motors when
starting up the machine initially and after any alteration to the electrical connection(s) or switch gear,
to check that the oil pump and the fan function properly
20 Maintenance and repair work should be recorded in an operator’s logbook for all machinery.
Frequency and nature of repairs can reveal unsafe conditions.
21 When hot parts have to be handled, e.g. shrink fitting, special heat-resistant gloves shall be used and,
if required, other body protection shall be applied.
22 When using cartridge type breathing filter equipment, ascertain that the correct type of cartridge is
used and that its useful service life is not surpassed.
23 Make sure that oil, solvents and other substances likely to pollute the environment are properly
disposed of.
24 Before clearing the unit for use after maintenance or overhaul, check that operating pressures,
temperatures and speeds are correct and that the control and shutdown devices function correctly.
1.6 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.
1.7 Specific 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.
