POWER SUPPLY
• This material is designed to be powered by a 3-phase 200V/240V power supply only (50-60 Hz) with four wires with a neutral one connected to the
earth and fitted with a ≥ 50 A D-rated circuit breaker (or aM type fuse).
The permanent current absorbed (l1p or ILp) displayed in the section «technical specifications» of this manual relates to use at maximum power.
Check that the power supply and its protection (fuse and/or circuit breaker) are compatible with the current needed by the machine. In some
countries, it may be necessary to change the plug to allow the use at maximum settings.
• Power supply recommendations :
In order to limit the voltage drop in the power supply line and to avoid any risk of disconnection of the protection, it is imperative to connect the
equipment to a «dedicated» socket. This plug must be connected to the electrical panel and only power this equipment. The protection rating must
be determined taking into account the following constraints:
Check the cross-section of the cable reaching the connection socket: 4 x 16 mm² (6 AWG). If the power line from the switchboard is longer than 10
m, use a conductor cross-section of 25 mm² (4 AWG). If you are using an extension cable, use a conductor cross-section of 16 mm² (6 AWG) and 25
mm² ( 4 AWG) if the length of the line + extension > 10 m.

Neutral (not used)
• The device turns into protection mode if the power supply tension is below or above the 15% or in the case of no phase. To indicate this default,
the screen displays an error code.
• In order to ensure optimal functioning of the equipment, check that the compressed air circuit can supply 8 bar (116 Psi) and then connect the air
supply to the back of the machine. The machine must not be used on an air network with a pressure under 4 bar (58 Psi) or over 10 bar (145 Psi).
CONNECTION TO A GENERATOR
The equipment is not protected against the regular overvoltage waves emitted by the power generator. It is therefore not recommended to connect
them on this type of power supply.
REFILL OF THE COOLING LIQUID TANK
The cooling liquid recommended by CHIEF must be used:
5 l: ref. 062511 • 10 l : ref. 052246
The use of other cooling liquids, especially standard automotive liquid, can lead, through electrolysis, to the accumulation of solid deposits in the coo-
ling system, reducing the cooling, and may even lead to system block. Any damage to the machine caused by the use of another coolant is excluded
from the warranty.
Using purely the recommended coolant provide antifreeze protection down to -20°C (-4°F). It can be diluted, but only by using de-ionised water; do
not use tap water to mix with the coolant! In all cases, at least one 10-litre bottle must be used to provide minimum protection for the cooling system.
30 litres of liquid
protection antifreeze down to -20°C (-4°F)
20 litres of 10 litres of deionised water
protection antifreeze down to -13° (9°F)
10 litres of 20 litres of deionised water
protection antifreeze down to -5° (23°F)
Any damage resulting from frost will not be covered by the warranty.
To refill the cooling liquid tank, proceed as follows :
- Put the pneumatic clamp on its support.
- Use the spout provided for filling.
- Pour 30 litres of liquid to reach half of the level indicated.
Safety data concerning the liquid:
- in case of contact with eyes, remove contact lenses if worn and rinse thoroughly using clear water for several minutes. Seek medical
advice.
- in case of contact with the skin, clean thoroughly using soap and remove any contaminated clothing immediately. Seek medical
advice if the skin gets irritated.
- in case of the liquid being swallowed, rinse the mouth abundantly using clear water. Drink plenty of water. Seek medical advice.
