Methods to prevent freezing

Ice formation in the air motor can occur when the
ambient air temperature is 32-50 °F (0–10°C) and
the relative humidity is high.
Take the following action to further counteract the
risk of ice formation:
♦ Use a water separator.

Lubrication

For problem-free operation, continuous lubrication
of the air motor is required. Before using and after
each eight hours service, remove oil plug and fill
reservoir with recommended oil, see below.
Temperature
Lubricant range °F (°C)
Air tool oil ≤100
(≤38)
Air tool oil >100
(>38)
Grease
Use a high quality bearing grease recommended for
use in ball bearings.
NOTICE Automotive water pump grease is
designed for use with hot water and is too hard for
use in a pump operating in cold liquids.
NOTICE The venting hole (see section "Main
parts") must always be left open in order to secure
lubrication of the lower ball bearing.
Oiler adjustment
The oiler valve is factory set to deliver approximately
six ounces (180 g) of oil in each eight hours service.
Check the lubrication by holding a piece of clean
paper in front of the air exhaust while operating the
pump. After about five seconds traces of oil should
appear on the paper.
If readjustment is necessary, proceed as follows:
Remove oil plug and drain all oil out of
1)
reservoir.
Unscrew and remove four nuts with lock
2)
washers holding governor housing to motor
housing and remove governor housing.
Remove oil filter washer from governor
3)
housing and rotate oiler valve. Clockwise
rotation reduces flow. Counter clockwise
rotation increases flow.
4) Reassemble, refill and check the lubrication as
described above.

Safety and operating instructions
NOTICE The oiler valve may stick to the oiler valve
seat when the seat is screwed in. Check by inserting
a small pin through the hole in the seat. It should
be possible to feel the valve move against the oiler
valve spring.
NOTICE Do not restrict flow entirely as lack of
lubrication will result in rapid pump failure.

Operation

WARNING Involuntary start
Involuntary start of the machine may cause injury.
Keep your hands away from the start and stop
►
device until you are ready to start the machine.
Learn how the machine is switched off in the event
►
of an emergency.
► Stop the machine immediately in all cases of
power supply interruption.

Preparations before starting

> Blow the compressed air hose clean before
connecting it to the pump.
> If the pump has not been in use for a longer
period of time, pour approximately 1
of oil directly into the air intake of the pump. This
will ensure good lubrication right from the start.
> Check that the compressed air is free of water and
other impurities. Dry air is particularly important
when using a muffler, because a muffler increases
the risk of ice formation.

Start and stop

WARNING Whipping discharge hose
A discharge hose that comes loose can lash around,
and the hose or jets of liquid can hit the operator,
and cause personal injury or death. To reduce this
risk:
► Always remove kinks, before the pump is started.
If the discharge hose is kinked, it can be forced
out of the operator's hands.
Always make sure that the discharge hose
►
connections are properly attached.
► Check that the discharge hose and the
connections are not damaged, replace if
necessary.
► Always make sure that the outlet end of the
discharge hose is properly secured.
