Installation, precautions
DANGER Whipping air hose
A compressed air hose that comes loose can lash
around and cause personal injury or death. To reduce
this risk:
►Check that the compressed air hose and the
connections are not damaged, replace if
necessary.
►Check that all compressed air connections are
properly attached.
►Never carry a pneumatic machine by the air hose.
►Never attempt to disconnect a compressed air
hose that is pressurized. First switch off the
compressed air at the compressor and then bleed
the machine by activating the start and stop
device.
►Do not use quick disconnect couplings at tool inlet.
Use hardened steel (or material with comparable
shock resistance) threaded hose fittings.
►Whenever universal twist couplings (claw
couplings) are used, we recommend that lock pins
are installed and whipcheck safety cables are used
to safeguard against possible hose to tool and
hose to hose connection failure.
►Never point a compressed air hose at yourself or
anyone else. To avoid the risk of getting injured,
never use compressed air to blow for example
dust, dirt etc. from your clothes.
Operation, precautions
DANGER Pressurized lubricator hazard
When the lubricator is connected to a compressed
air line, the oil chamber is pressurized. If the filler
plug is loosened, there is a risk of oil being ejected
which can cause personal injury.
►Always disconnect the lubricator from the
compressed air line before loosening the filler plug.

Safety and operating instructionsCLG 10, 10 US, 30, 30 US

Overview
To reduce the risk of serious injury or death to
yourself or others, read the Safety instructions
section found on the previous pages of this
manual before operating the machine.
Design and function
CLG 10 and CLG 30 are designed to lubricate
compressed air equipment, using mineral- or
synthetic oil. No other use is permitted.
Air flows into the lubricator through the inlet. Some
of the air flows into the oil chamber, via the check
valve, while the rest flows through the through-flow
pipe. When compressed air enters the oil chamber,
the oil becomes pressurized. This presses it up
through the oil pipe, through both the pipe opening
and small holes drilled in the pipe up to the valve
cone.
As the air through-flow pipe narrows just before the
point at which it is met by the oil duct (venturi tube),
there is an increase in air velocity and a decrease in
the air pressure.
The small pressure differential which now exists
between the oil chamber and the air through-flow
pipe (after the venturi), causes oil to be pressed up
into the through-flow pipe, via the valve cone.
The oil becomes atomised as it enters the
through-flow pipe, and is thus carried in the air supply
to the pneumatic machine.

♦There is a an arrow on the lubricator to indicate
the correct direction of air flow. When connecting
the lubricator, make sure that the arrow points in
the same direction as the air flow.
Lubrication
The lubricant is important for the pneumatic
machine’s function and has a great impact on the
useful service life. To guarantee good lubrication,
the length of the air hose between the lubricator and
the pneumatic machine must not exceed 3 meters.

For the correct recommended lubrication oil, refer to
the Safety and operating instruction for the pneumatic
machine used together with the lubricator.
Oil adjustment
CLG 10 and 30 are delivered with the oil dosage
screw in the fully open position. The oil dosage screw
can be turned through a total of four complete turns.
It is steplessly adjustable.
To adjust the oil dosage, do the following:
♦Use a screwdriver to turn the oil dosage screw.
Clockwise reduces oil flow.
Anticlockwise increases oil flow.
♦Never remove the spring pin. If the oil dosage
screw become loose, the spring pin will prevent it
from blowing out of the lubricator.
♦Check the exhaust port of the pneumatic machine
to see that sufficent lubrication is being exhausted.
Operation
Operating
Filling the lubricator with oil
Always top up the lubricator with oil at the start of
the shift.
♦Switch off the air supply to the lubricator.
♦Vent the air line, to remove trapped air.
♦Clean around the outside of the filler plug to
prevent dirt from entering the lubricator.

♦Unscrew the filler plug by two turns, which opens
the venting duct and releases any remaining
compressed air in the lubricator.
♦Fill the lubricator with oil.
♦Re-fit and tighten the filler plug. The lubricator is
now ready for use.
Maintenance
Regular maintenance is a basic requirement for the
continued safe and efficient use of the lubricator.
Follow the maintenance instructions carefully.
♦Before starting maintenance on the lubricator,
clean it in order to avoid exposure to hazardous
substances.
♦Use only authorised parts. Any damage or
malfunction caused by the use of unauthorised
parts is not covered by warranty or product liability.
♦When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory
ventilation.
♦For major service to the lubricator, contact your
nearest authorised workshop.
Every day
Before undertaking any maintenance on the
lubricator, always switch off the air supply and then
disconnect the air hose from the lubricator.
♦Clean and inspect the lubricator and its functions
each day before work commences.
♦Conduct a general inspection for leaks and
damage.
♦Check that the claw couplings are tightened and
free from damage.
♦Change damaged parts immediately.
♦Replace worn components in good time.
♦Make sure that all the attached and related
equipment, such as hoses are properly
maintained.
Periodic maintenance
Once a year the lubricator must be dismantled and
all parts be cleaned and checked. This work must
be performed by authorised staff, trained for this task.
Assembly instruction
When reassembling the claw couplings on the
lubricator, apply LOCTITE® 577™ (LOCTITE is a
registered trademark of Henkel Corporation. 577 is

Storage
●Clean the lubricator properly before storage, in
order to avoid hazardous substances.
●If the lubricator is stored filled with oil, place it with
the filler plug upwards to prevent oil from leaking
out through the mouth of the air pipe.
●Always store the lubricator in a dry place.
Disposal
A used machine must be treated and disposed of in
such a way that the greatest possible portion of the
material can be recycled and any negative influence
on the environment is kept as low as possible, and
in respect to local restrictions.
