Dual Stage Rotary Vane Vacuum Pump
Part # 6907
Description
• The two-stage, offset rotary vane design provides
powerful, quiet, high vacuum capability and
ensures moisture removal, while the high pumping
capacity reduces evacuation time.
• The design of the dual-stage rotor improves ultimate
vacuum and extraction rate, reduces the exhaust
time of the pump, and ensures the complete
removal of refrigerant and moisture from the system.
• The long-acting inlet filter can effectively prevent
contaminants from entering the pump chamber,
and can effectively separate the oil mist from the
exhaust gas.
• Smaller size and lighter weight makes it more
convenient to carry and use.
• Comfortable and strong handle is reliable to use
during operation.
• Quality materials - aluminum oil tank bracket and
motor housing make the pump lighter and the met-
al base secures the unit during use.

WARNINGS OPERATION GUIDE (continued)
Safety Warnings
To avoid personal injury, please read entire instruction manual prior to
using the unit.
Always wear protective gloves and eyewear when working with
refrigerant. Avoid contact of refrigerant with skin or eyes.
This vacuum pump may produce sparks and is not to be used with any
flammable gases, including R-32, R-600a, and R-1234yf.
To ensure the safety of the product, please use a 18V 6AH lithium battery
from a reputable manufacturer.
Never disassemble, open or cut battery pack. Keep away from heat
source and direct sunlight.
Keep the battery and its contacts clean and dry. Do not use if damaged
or if there is a discharge.
Do not use this product in the rain or in any situation where water, snow or
ice may contact the unit. To do so might cause electrical shock.
When the battery is discharged, turn off the vacuum pump.
4 OPERATION GUIDE
Pump Operation
1. Check to ensure the power supply used is consistent with the
power supply voltage and frequency marked on the product
nameplate.
2. Switch the pump to “off” before connecting the power supply.
3. Remove the exhaust cap on the catcher and turn power “on”
to begin operation.
4. When refueling, keep the oil level between the lower and
upper limits. If the oil level is too low, the performance of the
pump will be reduces, andif it is too high, oil mist will be
expelled.
5. Confirm that the extraction container and hoses have no
leaks.
6. After use close the valve between the pump and container.
Turn the power switch off. Remove connecting hose.
7. Close air inlet cap and exhaust cap to prevent contamination.
Battery Charging
Note: Battery is sold separately. Manufacturer’s instructions
supercede these instructions.
1. Remove the battery from the vacuum pump and insert it into
the charger.
2. Ensure the power supply voltage used is connected with the
input voltage of the charger.
3. If the charging indicator is red, it means the battery is
charging. If the indicator is green, it means it is fully charged.
4. It is normal for the battery shell to feel warm during charging.
5. If the vacuum pump will be idle for an extended period of
time, the battery should be removed.
6. The battery should be fully charged prior to use.
7. Ambient temperature should be between 50—110° during
charging.
5 MAINTENANCE AND REPAIR
1. Use appropriate vacuum pump oil. We recommend FJC
Vacuum Pump Oil, Part # 2202 (8 oz) or 2200 (Quart).
2. If the pump oil appears cloudy or polluted, change the oil us-
ing the following instructions:
• To ensure the pump is in a “hot” state, run the pump for one
minute prior to the oil change.
• Open the air inlet while the pump is running so that the oil in
the pump cavity flows out. Close the switch to stop the pump
and open the drain plug to discharge the waste oil.
• Properly dispose of waste oil, following federal, state and local
regulations.
• When the oil stops flowing, tilt the vacuum pump to
completely drain the unit.
• Tighten the drain plug.
• Open the trap and add new pump oil.
• Cover the air intake valve, check the oil level after running the
pump for one minute. Add more if needed. Screw on trap.
