Assembly

BBD 12T/TS
Press the bushings and handles (A) onto each
1)
side of the back head.
2) Secure the handles by tapping the spring pins
(B) into the back head.

Lubricate

After unpacking and installing the tool, pour a liberal
amount of lubrication oil in the air connection.

Hoses and connections

Compressed air source
A.
Water separator (optional)
B.
C. Lubricator (optional)
Max. 3 meter compressed air hose between
D.
the lubricator and the machine.
Check that you are using the correct
♦
recommended operating pressure, 6 bar (e).
The maximum permissible air pressure, 7 bar (e),
♦
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
meters, a hose with a minimum internal diameter
of 19 mm (3/4") should be used. If the hose length
is between 30 and 100 meters, a hose with a
minimum internal diameter of 25 mm (1") should
be used.

Safety and operating instructions

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 CLG 30
lubricator connected to the air line.
Use Atlas Copco Rock Drill AIR-OIL which is
specially developed for BBC, BBD and RH pneumatic
Rock drills. Rock Drill AIR-OIL is readily
biodegradable according to OECD 301 and has high
film strength that can withstand heavy loads. If Rock
Drill AIR-OIL is not available use a mineral-based air
tool oil with the properties recommended in the table
below.
