Powerscreen XA750S - Warning of Special Dangers

02-12
Safety Hazards
7. The electrical equipment of the machine is to
be inspected and checked at regular intervals.
Defects such as loose connections or scorched
or otherwise damaged cables must be recti󰘰ed
immediately.
8. Necessary work on live parts and elements must
be carried out only in the presence of a second
person, who can cut o󰘯 the power supply in
the case of danger by actuating the emergency
shut o󰘯 or main power switch. Secure the
working area with a red and white safety chain
and a warning sign. Use insulated tools only.
9. Before starting work on high voltage assemblies
and after cutting out the power supply,
the feeder cable must be grounded and
components such as capacitors short-circuited
with a grounding rod.
10. Tracked machines are wired with negative
earth. Always observe correct polarity.
11. Always disconnect battery leads before
carrying out any maintenance to the electrical
system.
12. If welding is to be carried out on the machine
it is essential that the power pack is isolated,
refer to servicing safety & precautions.
13. The batteries contain sulphuric acid, an
electrolyte which can cause severe burns and
produce explosive gases.
14. Avoid contact with the skin, eyes or clothing.
Electric Energy
1. Use only original fuses with the speci󰘰ed current
rating. Switch o󰘯 the machine immediately if
trouble occurs in the electrical system.
2. Plants with high voltage electrical equipment
must be suitably earth bonded by a quali󰘰ed
electrician prior to activating the main isolator
switch.
3. When working with the machine, maintain a safe
distance from overhead electric lines. If work
is to be carried out close to overhead lines,
the working equipment must be kept well away
from them. Check out the prescribed safety
distances.
4. If your machine comes into contact with a live
wire:
Warning of Special Dangers
Warn others against approaching and
touching the machine.
Have the live wire de-energised.
5. Work on the electrical system or equipment may
only be carried out by a skilled and quali󰘰ed
electrician or by specially instructed personnel
under the control and supervision of such an
electrician and in accordance with applicable
electrical engineering rules.
6. If provided for in the regulations, the power
supply to parts of machines and machines, on
which inspection, maintenance and repair work
is to be carried out, must be cut o󰘯. Before
starting any work, check the de-energised parts
for presence of power and ground or short
circuit them in addition to insulating adjacent
live parts and elements.
