[Before starting operation: Oil filling]
1. Open the oil inlet and fill the pump with pump oil as provided approximately up to the middle of the level glass.
[Note] Never fill any other oil than the one exclusively used for vacuum pumps. Also, be careful not to fill the oil
excessively.
2. After filling oil, close the oil inlet.
For change oil, high-performance TA117-1 to 3 manufactured by TASCO is recommended regardless of high
or low temperature.
[Gas ballast valve]
Oil deterioration caused by moisture and condensable gas absorption into the pump oil can be prevented by operating with
the gas ballast valve opened and letting dry air flow into the pump.
(Oil cleaning operation)
Close the suction port valve of the connected manifold and operate with the gas ballast valve opened for 5 to 10 minutes,
then the oil temperature will rise and vaporize moisture and condensable gas absorbed in the pump oil which is thus purified.
Please perform normal vacuuming operation with the gas ballast valve closed.

[Example of operating procedure]
[1] Connect the vacuum pump, gauge manifold and air conditioner as per the [Connection example] shown below.
[2] Confirm with the gauge that it is not under any pressure.
* If any CFC (chlorofluorocarbon) or nitrogen gas enters the vacuum pump, oil may be blown off from the muffler or
damage may be caused thereby.
[3] Confirm that the manifold valve on the high pressure side is closed and then switch ON the power of the vacuum pump
and open the vacuum pump valve and the manifold vale on the low pressure side.
[4] Perform vacuuming for a specified time in accordance with the instruction manual of the air conditioner manufacturer.
[5] Close the low pressure valve of the manifold, close the vacuum pump valve and, thereafter, switch OFF the power of the
vacuum pump.
[6] Confirm the gauge pressure, leave it for a few minutes and if the gauge pressure as reconfirmed then shows the same
value as confirmed before, there has been no leakage in the system and the vacuum operation can be confirmed as
having been completed.

2. In performing a task, put on safety shoes, a helmet, protective eyeglasses, working clothes, etc. without fail.
3. Never use or store the product as exposed to rainy conditions.
4. For transporting the equipment, never pull the power cable but hold the handle to carry it.
5. Never fill any other oil than the one for vacuum pumps. It may cause damage.
6. Ensure to provide grounding and be fully cautious of electric leakage.
7. Use the power switch when the power is to be cut off. Never pull the power cord to cut the power OFF.
8. Peruse the attached safety notes, understand them fully and use the product.

[Oil change]
As vacuuming operation is repeated, the oil may get contaminated and deteriorate.
If the deteriorated oil is used, the degree of vacuum may fall down and the product may become incapable of performing
properly.Also, if the deteriorated oil continues to be used, it may impose additional load on the vacuum pump rotor and
cause vacuum pump failure. Oil change shall be performed periodically. (Topping up is prohibited.)
1. Open the oil drain and evacuate oil therefrom.And after closing the oil drain, fill new oil into the oil inlet.
In the event contamination is still severe;
2. Cleaning the pump is recommended after the old oil has been evacuated and prior to filling the new oil. For cleansing
operation, new oil shall be used.
a) Close the oil drain and inject about 20 to 30 cc of new oil into the oil inlet.
Evacuate the contaminated oil from the oil drain. Thereafter start-up the vacuum pump and operate it for 30 seconds
or so. Repeat this operation until the oil gets clean.
b) Finally, fill an appropriate quantity of new oil.
For change oil, high-performance TA117-1 to 3 manufactured by TASCO is recommended regardless of high or low
temperature.
As for vacuum pump oil, please use
TA117-1 to 3 which keeps the degree of
vacuum high in the summer season and
helps smooth start-up of the vacuum pump
without much burden thereon in the winter
season.
[Fuse change]
When the fuse has blown out, remove the cap of the fuse box, take out
the blown out fuse from the holder and replace it with the replacement
fuse which has been packed together when the new product was
purchased.

[When you are suspicious of a failure]
Trouble
Cause
Countermeasure
Start-up failure
(Start-up disabled,
chattering caused,
etc.)
[1]
Ambient temperature is too low.
Have the equipment accustomed to the temperature
of the room, etc. If the start-up instability still persists,
try to start-up with the suction port closed and
continue the warm-up operation for about 5 minutes.
[2]
Inadequate power source environment
(Voltage or power degradation due to
use of thin extension cord or too many
loads on one electrical outlet, etc.)
Never use power from an electrical outlet with too
many loads on. Use an extension cord with wire
diameter of 2.0 sq or larger and with length of 10 m
or shorter.
If the start-up instability still persists, try to start-up
with the suction port closed and continue the
warm-up operation for about 5 minutes.
[3]
Failure caused by the residual
pressure of the air conditioning system
increasing the internal pressure of the
pump.
Surrender the pump for inspection and repair.
[4]
Pump lock or motor failure due to
falling or other strong impact thereon.
Surrender the pump for inspection and repair.
Insufficient degree of
vacuum
[1]
System leakage
Repair the leakage of the piping, etc. of the air
conditioning system and then connect it with the
vacuum pump.
[2]
Poor sealing of charge hose or joint
section
Confirm the status of deterioration of the charge hose
or packings, etc. and provide a replacement for any
defective part if any.
[3]
Gas ballast valve is opened.
Close the gas ballast valve.
[4]
Oil is contaminated.
Change oil.
[5]
Oil quantity is inappropriate.
Adjust to an appropriate oil level.
[6]
Interfusion of foreign material into
pump
Change oil or surrender the pump for inspection and
repair.
[7]
Failure caused by the residual
pressure of the air conditioning system
increasing the internal pressure of the
pump.
Surrender the pump for inspection and repair.
[8]
Pump or motor failure due to falling or
other strong impact thereon.
Surrender the pump for inspection and repair.
[9]
Pump part attrition
Surrender the pump for inspection and repair.
Oil mist discharged
from exhaust muffler
[1]
It is normal when air is being sucked in.
[2]
Interfusion of foreign material into
suction valve
Operate for a given length of time and if mist is
discharged intensively even after the object
equipment has reached vacuum status, surrender
the pump for inspection and repair.
Oil leakage
[1]
Residual pressure of the air
conditioning system increasing the
internal pressure of the pump
Confirm that there is no residual pressure in the air
conditioning system and then connect it with the
vacuum pump.
[2]
Exhaust muffler leakage due to falling
sideways
Use and store the equipment in upright position.
[3]
Loosening of oil drain screws
Tighten the drain screws further up.
[4]

[5]
Defective sealing
Surrender the pump for inspection and repair.
Abnormal noise/
abnormal odor
[1]
Motor or pump failure
Surrender the pump for inspection and repair.
If abnormality persists even after the above has been confirmed, or if any other abnormality has been felt, stop the use
immediately and bring the equipment to the dealer where it was purchased.
