SAFETY INSTRUCTIONSWARNING!
This pump is intended to be manually operated for the purpose of delivering liquids
stored in drum cans. Do not use the pump for any other purpose.

Do not use the pump in a way, which may cause excessive inner pressure (use it
only manually). Operating the pump differently may result in leakage and fire.

Before transferring a liquid it is advised to carefully read information on liquid’suse.

In case of direct contact with liquid (ingestion, skin contamination etc.),
immediately proceed with safety procedures and seek medical attention.

When willing to transfer explosive or inflammable fluids, remember to ALWAYS
use a ground wire. Not using a ground wire may result in fire and explosion. During
the operation of the device, it is STRICTLY PROHIBITED to use fire!

Before changing the liquid, make sure you have removed any leftover liquid you
have transferred before. Not doing so may cause dangerous chemical reactions.

Always store the liquid in a place unreachable for children. Also, read theinstructions on how to properly store a liquid.

Remember – do not use fire when operating the device!

CAUTION!
Store the liquid in a safe place, unreachable for children.

If you believe the liquid may have affected your physical condition, immediately
seek medical attention.

Always remember about necessary safety measures according to the liquid’s usage
instructions.

Disassembly, reassembly and service are restricted to experts.

CAUTION!
Do not run the device in a dry state (with no liquid inside).



If the device suddenly stops operating, or operates in a strange manner,
immediately turn it off and contact the vendor, or an authorized service. Continuing
operation may result in fire and human injuries.

The device has a fixed direction of operation. Do not rotate the handle in a direction
opposite to the marking on the device.

Protect the main body of the device from shock. Do not drop it. Doing so may cause
malfunction of the device, and lead to leakage.

* Please remember, that the safety measures and warnings pointed out in this manual are not exhaustive for all
possible situations. Although we have designed our product to be as safe as possible, persons operating andmaintaining the device should strictly follow all safety rules in the operation/maintenance area.

performance may be lower)
CAUTION!
The liquids listed above are usable, however, because different operating conditions
and environmental conditions may affect the liquid, you should always decide on
your own whether it is safe to transfer the liquid, or not.

There are many different types of thinners. You should always check whether thesubstance can be safely transferred using this pump.

CAUTION (concerning high relative density fluids’ use)
When trying to transfer high relative density fluids (1.1~1.5), and experiencing
difficulties with suction or no suction at all, do not rotate the handle idly. Doing so may
result in inner vane’s damage.
Please follow the next steps:
1) Insert some of the liquid into delivery pipe.
2) Rotate the handle quickly (3~5 rotations/second)
If the pump still refuses to suck the liquid, please discontinue the operation.

USAGE INSTRUCTIONS
1. Take the adapter from pump’s main body and attach it to the drum can.
2. Insert the pump into the adapter and firmly fix it with set bolts.
3. Attach the handle to pump’s main body.
4. To transfer the liquid, rotate the handle in the direction marked on pump’s mainbody.
As far as HM model is concerned, remember to release the valve and thepeacock thread. Leaving them closed will prevent the transfer.

5. After use, before pulling out the HM model, remember to close the ball valve andfasten the peacock thread.
USAGE PRECAUTIONSWhen using the rotary pump, there is a possibility that tiny parts of pump’s main
body and vane may get into the fluid (because of the friction). If those parts shouldby all means not get into the liquid, please install a filter at the end of a delivery
pipe or delivery hose.

Due to pump’s inner parts’ abrasion, suction efficiency may decrease. In order torestore pump’s suction efficiency, the worn parts must be replaced.

When willing to transfer high relative density liquids, please refer to page 4.

Do not transfer liquids, which tend to thicken when in contact with air.

Please do not cause shock to the handle. Also, do not operate the handle with toomuch force. This may cause damage to the rotor, as well as result in leakage.

Instructions on handle assembly:
(21) After making sure that the set bolt is inserted into
the axial set’s hole, please fasten the set bolt, however,
not excessively. Excessive tightening may result indamaging the handle.

(31) Tighten the nut. (21) Firmly fix the set bolt.
