SAVE THESE INSTRUCTIONS
WORK AREA
zKeep work area clean, free of clutter and well lit. Cluttered and dark work areas can cause
accidents.
zDo not use your tool where there is a risk of causing a fire or an explosion; e.g. in the
presence of flammable liquids, gasses, or dust. Power tools create sparks, which may ignite the
dust or fumes.
zKeep children and bystanders away while operating a power tool. Distractions can cause you
to lose control, so visitors should remain at a safe distance from the work area.
zBe aware of all power lines, electrical circuits, water pipes and other mechanical hazards in
your work area, particularly those hazards below the work surface hidden from the operator’s
view that may be unintentionally contacted and may cause personal harm or property damage.
zBe alert of your surroundings. Using power tools in confined work areas may put you
dangerously close to cutting tools and rotating parts.
PERSONAL SAFETY
zStay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.
zDress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught
in moving parts. Air vents often cover moving parts and should be avoided.
zUse safety apparel and equipment. Use safety goggles or safety glasses with side shields
which comply with current national standards, or when needed, a face shield. Use as dust
mask in dusty work conditions. This applies to all persons in the work area. Also use non-skid
safety shoes, hardhat, gloves, dust collection systems, and hearing protection when
appropriate.
zAvoid accidental starting. Ensure the switch is in the off position before plugging tool into
power outlet. In the event of a power failure, while a tool is being used, turn the switch off to
prevent surprise starting when power is restored.
zDo not overreach. Keep proper footing and balance at all times.
zRemove adjusting keys or wrenches before connecting to the power supply or turning on the
tool. A wrench or key that is left attached to a rotating part of the tool may result in personal
injury.
PNEUMATIC TOOL USE AND CARE
zNever use a tool with a malfunctioning switch. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired by an authorized service representative before
using.
zCheck for misalignment or binding of moving parts, breakage of parts, damaged air hose (not
included) and any other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
zCompressed air only. Only use clean, dry and regulated compressed air at no more than
80–95 PSI to power this tool. Never use oxygen, carbon dioxide or any other bottled gas as a

Page 4 of 10
power source for this tool.
zUse proper size and type air pressure line and fittings. The recommended air line for this tool
is 1/4”, delivering no more than 115PSI. Recommended air inlet size is 1/4”.
zUse air hoses rated for safe operation of the tool. Air hoses rated for a maximum of 140PSI or
greater must be used with this tool.
zMake sure the hose is free of obstructions or snags. Entangled hoses can cause loss of
balance or footing.

TOOL USE and PERSONAL SAFETY
When the pump is connected to the compressed air supply:
1. The compressed air must be filtered to avoid dust and moisture into pump
2. The max compressed air pressure must not exceed 0.8Mpa/120PSI (recommended air pressure
is 80-95 PSI).
3. To deliver oil, press the knob on the delivery pistol; delivery stops when the knob is released but
the whole system remains under pressure
4. Position the pistol so that the circuit can’t open accidentally. Otherwise oil could leak onto the
ground.
5. Never point the pistol at people or object.
6. Always cut off the air supply after use so that oil can’t leak out.
7. Use only original spare parts in case the pump has to be repaired or its components have to be
replaced
8. Empty all the oil from the pump in case it has to be disposed of
9. When not in use, turn off compressed air to stop pump
10. Do not use the pump near open flames. Do not smoke during this operation
11. Wear oil-proof gloves
12. Do not throw the oil away. Used oil has to be disposed of according to national environmental
regulations
13. The pumps can be used only to deliver lubricants, used oil or antifreeze liquids. Do not use the
pump for any other substance
OPERATION
Directly Fitted Pump into the Drum
1. Insert the suction tube of pump into the drum and secure with ring nut, suitable for commercial
drums with 57 diameter hole and threading 2” NPT.
2. Fit an oil delivery tube for oil outlet of the air operated pump using only high quality tubes
(normally 3/4”, according to DIN-SAE norms), by means of 3/4” NPT threading fitting.
3. Oil delivery pistol: Connect delivery tube with delivery pistol using suitable pipe fittings, and point
the pistol at right place.
4. Air inlet connection is 1/4” quick plug (or 1/4” NPT female) in all versions. Compressed air
connection (to be supplied by the customer) should be done using suitable tube.
5. A pressure regulator to keep the pump’s working pressure at the best possible level (72-116
max PSI) between the pump and the compressed air line.
6. A cut-off switch can enable the operator to stop the pump at any given moment by cutting the air
supply off between the pump and the compressed air line.
7. Switch on all switches.

MAINTENANCE
WARNING: Make sure this tool is disconnected from its air supply before attempting any
maintenance, cleaning, or inspection.
Pumps are delivered in appropriate carton boxes. Packaging material should be properly disposed.
Handling and storage of the new pump do not require any special procedures.
However after the pump has been used, empty the used oil in the suction tube into an appropriate
container. This is done by overturning the pump.
The dust in compressed air can slow down and even block the motor cylinder. The following steps
may prevent this from happening:
1) Add 2 ounces of approved lubricating oil to the air inlet hole weekly, operate the pump for
several minutes after having lubricated it.
2) Turn on the pump for several minutes until moving parts are fully lubricated.
3) You may repeat the above operation if necessary.
4) The above steps should be carried out on a weekly basis, at minimum.
For the pumps that are attached with compressed air treatment equipment, please empty the water
retained in the reservoir of the filter-purger frequently.
For the pumps that are attached with a lubricator, please pay close attention to the lubricator’s oil
level and refill with SAE 20, SAE 30 or antifreeze oil for extreme conditions when necessary.

Note:
The user should perform only routine maintenance operations (such as filters, silencers, cleaning…)
with the pump in order not to damage it or compromise its safety.
Contact our sales or service center when the pump needs further maintenance.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment,
such as those dust masks that are specially designed to filter out microscopic particles.
