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 Breaker and hammer AIR-OIL
as a lubricant. Breaker and hammer AIR-OIL
counteracts freezing.
Use a water separator.
♦
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 lubricant is important for the machine's function
and has a great impact on the useful service life. If
there is no integrated lubricator, then connect a
separate lubricator to the air hose. To guarantee
good lubrication, the length of the air hose between
the separate lubricator and the pneumatic machine
should not exceed 3 meters.
Use a synthetic lubricant such as Atlas Copco
Breaker and hammer AIR-OIL or mineral oil with the
properties recommended in the table below.

Checking the oil level and filling the
integrated lubricator
Check the oil level daily.
♦
Place the machine vertically, when checking the
♦
oil level, and filling lubricant.
Wipe clean around the oil plug and remove it.
♦
Check that the threads are not damaged or worn
♦
out. Always replace parts with damaged or worn
out threads.
Check the O-ring (A). If the O-ring is missing or
♦
damaged, replace it immediately.
See the table for correct lubricant.
♦
♦
Fill lubricant to the 'lowest' thread (B).
Tighten the plug firmly by hand and wipe off any
♦
excessive oil.
Insertion tool
CAUTION Hot insertion tool
The tip of the insertion tool can become hot and
sharp when used. Touching it can lead to burns and
cuts.
Never touch a hot or sharp insertion tool.
►
Wait until the insertion tool has cooled down before
►
carrying out maintenance work.
