SAFETY INSTRUCTIONS
WARNING: No complying with below requests will result in severely harm to your
body even death.
Oil pump misuse hazard: Oil pump misuse can cause the to rupture, malfunction
• Read all instruction manuals, tags, and labels before operating the equipment.
• Use the equipment only for its intended purpose. If you are not sure, call your distributor.
• Do not alter or modify this equipment. Use only genuine parts and accessories.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not exceed the maximum working pressure of the lowest rated component in your system.
• Use fluids and solvents which are compatible with the equipment wetted parts. Refer to the
Technical Data section of all equipment manuals. Read the fluid and solvent manufacturer's
warnings.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon
solvents, or fluids containing such solvents in pressurized aluminum equipment. Such use
could result in a chemical reaction, with the possibility of explosion.
• Handle hoses carefully. Do not pull on hoses to move equipment.
• Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not lift pressurized equipment.

• Follow the Pressure Relief Procedure if the dispensing valve clogs before you clean, check or
service the equipment.
• Tighten all fluid connections before operating the equipment.
• Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
• Do not repair high pressure couplings; you must replace the entire hose.
MOVING PARTS HAZARD
Moving parts can pinch or amputate your fingers.
• Do not operate the pump with the air motor plates removed.
• Keep clear of all moving parts when starting or operating the pump.
• Before servicing the equipment, follow the Pressure Relief Procedure to prevent the
equipment from starting unexpectedly.
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition
and result in a fire or explosion and serious injury.
• Ground the equipment and the object being lubricated.
• If there is any static sparking or you feel an electric shock while using this equipment, stop
dispensing immediately. Do not use the equipment until you identify and correct the problem.
• Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
dispensed
• Keep the dispensing area free of debris, including solvent, rags, and gasoline.
• Do not smoke in the dispensing area.

Pump:
Use a ground wire and clamp as the Fig.2. Get rid of the grounding
screw, put the end of the grounding wire into the grounding hole.
Lock the bolt to the pump safety.
Air and Fluid hoses:
Grounding effectively.
Air compressor:
Follow manufacturer's recommendations.
Oil control valve:
Connect the pump with proper grounding wire, always hold a
metal part of the valve firmly to the side of a grounded metal
pail, then trigger the valve.
Barrel:
Use local applicable trolley. If it is metal barrel, put on the
device which is electric, can not put on insulative device

Standard installation
1: cut-off valve
2: Filter
3: Regulator
4: Lubricator
5: Control valve
6: Locking adapter
7: Hose reel
The above installation is not the integrated oil supply system, just contact the manufacture or
distributor if you need. Installation for air circle.
Note: Do not hang any device at the air inlet, as there maybe dropping and damage.
Process
• Put the pump into lock adapter (Fig .3 Parts 6), Install to the trolley.
• Install cut-off valve (Fig3. Part1).
• Install filter (Fig 3. Part 2).
• Install regulator which control the speed and adjust the air pressure (Fig3. Part3).
• Install lubricator which with self-lubricate (Fig3. Part 4).
• Install control valve which control flux，When the speed is too fast, pump will be self-close
automatic to avoid pump be damaged (Fig.3 Parts5).
• Connect oil output.
OPERATION
Pressure Relief
Injury for skin: Before pressure relief by manual，Pump is under pressure。To reduce the
risk of serious injury from pressurized fluid, accidental spray from the valve, or splashing fluid,
follow this procedure whenever you
• Are instructed to relieve pressure
• Stop dispensing
• Check, clean, or service any system equipment
• Install or clean dispensing devices
Pressure Relief procedure
• Turn off the cut-off valve, shut off air
• Put the pump to the waste equipments, switch oil valve ,relief pressure
• Turn the air supply and oil fluid.
• Turn off the oil valve.
When occurs：
• Problems on control valve, flexible hose, rigid tube or manual tip, auto tip.
• Pressure not relieve thoroughly according to above relief procedure.
• Pressure relieved very slowly until relieved thoroughly. Please clear obstruction of oil system.

WARNING: Each device with different max working pressure. To reduce the risk
of exceed pressure. Make sure the max work pressure for each device. Rated
pressure in the system can not exceed the max pressure of any device. Or there
will be burst, explosion, malfunction, serious damage.
Remind: Pump can not operate with empty load. Or the speed will be very fast which will
self-damage.
If acceleration is too fast or running very slow, Should stop operation and check that if there is
enough oil in the barrel. If there is insufficient oil, change the trolley and initialize the whole
system.
Startup
• If there is several pump in the whole system, please use control valve to dispatch the air.
• Open the main control valve.
• Open the oil valve which with effective grounding with the trolley. Keep the connecting of the
metal forboth oil valve and trolley. Open the cut-off valve, pump start to work. When the pump
is stable. Close theoil valve.
• If there are several pumps in the whole system, startup for each pump step by step with
above instruction.
• To get perfect result, set up the min air pressure for each device.
• Pump can not operate under empty load.
• Relief pressure before close the pump.
TROUBLE SHOOTING
WARNING: To reduce the risk of serious injury whenever you are instructed to
relieve pressure. Do not remove silencer, or it may cause finger be injury.
Before check and maintain, pay more attention of the relieve of pressure.
