Safety and operating instructions
Check that you are using the correct
♦
recommended operating pressure, 6 bar (e) (87
psi).
The maximum permissible air pressure, 7 bar (e)
♦
(102 psi), must not be exceeded.
Blow any impurities out of the compressed air hose
♦
before connecting it to the machine.
Select the correct dimension and length for the
♦
compressed air hose. For hose lengths up to 30
m (100 ft), a hose with a minimum internal
diameter of 19 mm (3/4 in.) must be used. If the
hose length is between 30 and 100 m (100 and
330 ft), a hose with a minimum internal diameter
of 25 mm (1 in.) must be used.
Methods to prevent freezing
Ice formation in the silencer can occur when the
ambient air temperature is 0–10°C (32-50 °F) and
the relative humidity is high.
The machine is designed to avoid the formation of
ice in the silencer. Despite this, under extreme
conditions ice can form in the silencer.
Take the following actions to further counteract the
risk of ice formation:
Use Atlas Copco Rock Drill AIR-OIL as a lubricant.
♦
♦ Use VAM 5A water separator.
If the rock drill freeze, never heat it to melt the ice.
Always let the ice thaw at room temperature.
Never pour methylated spirits or similar substances
into the rock drill, as they will interfere with the
lubrication and lead to increased wear.
Connecting a water separator
The length of the air hose between the compressor
and the water separator must be such that the water
vapor is cooled and condenses in the hose before
reaching the water separator.
If the ambient temperature is below 0 °C (32 °F) the
hose must be short enough to prevent the water from
freezing before reaching the water separator.
Lubrication
The rock drill is lubricated with oil mixed with
compressed air, which is taken to the parts that need
continuous lubrication. Oil is metered into the
compressed air using an Atlas Copco BLG 30 or
CLG 30 lubricator connected to the air line.
