General power tool safety warnings

WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
7. Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool.

Personal safety

1. Stay 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.

Battery protection system

The pump or battery is equipped with a battery protection system. This system automatically cuts off power to the motor to extend battery life.
The pump will automatically stop during operation if the pump and/or battery are placed under one of the following conditions:

Overloaded:
The pump or battery is operated in a manner that causes it to draw an abnormally high current.
In this situation, turn the pump off and stop the application that caused the pump to become overloaded. Then turn the pump on to restart.
If the pump does not start, the battery is overheated.
In this situation, let the battery cool before turning the pump on again.

Low battery voltage:
The remaining battery capacity is too low and the pump will not operate. In this situation, remove and recharge the battery.

Indicating the remaining battery capacity

Only for battery cartridges with the indicator

1. Connect the pump, manifold and outdoor unit with hoses.
   NOTE: When the size of the service port on the unit is 1/4″, use the supplied different diameter adapter.

2. Check that the high side and low side valves of the manifold are closed.

3. Install the two batteries to the pump. (See “Installing or removing battery cartridge” for the installation method.)

4. Open the gas ballast valve.

5. Turn the pump on. The LED lamp (RED) lights up and the motor operates.

6. Open the low side valve and high side valve of the manifold.

7. Close the gas ballast valve after 5 to 10 minutes.
   NOTE : The gas ballast valve is used to remove water (vapour) and condensable gas (taken into the pump during exhaust) from oil. If the condensable gas liquifies and gets into oil, it can cause a decrease in lubricity, and shorten the service life of the pump and seal. When the air enters from the gas ballast valve, the condensed gas remains as it is, and is exhausted with air.
   It is recommended to warm up the pump before operation because the more pump temperature is high, the higher gas ballast efficiency can be obtained.

8. When the remaining capacity of the battery (on the Left port) becomes empty, the power supply automatically changes to the battery (on the Right port). Remove the battery L, and replace it with a spare battery. When the remaining capacity of battery R becomes empty, the power supply changes to the battery L again. The pump can be operated for a long time by using the charged spare batteries repeatedly for L-R-L-R.
   WARNING: The pump becomes hot during operation and immediately after stopping. Do not touch the area around pump while it is hot. Doing so may result in burns or other accidents.
   NOTE: The motor may not operate when it is cold (5°C or less). In these cases, bring the pump indoors and allow it to warm up.

9. When the specified vacuum (refer to the manual provided by the air conditioner manufacturer) is reached, close the low side valve of the manifold.

10. Turn the pump off.

Airtightness test
There are no leaks if the pressure of the manifold does not rise for 5 minutes or more after leaving the pump and manifold.

NOTE: When the battery remaining capacity becomes low, LED lamp goes out and at the same time a long alarm beep start sounding. About two minutes later the motor stops. And then alarm beep changes into a repeated short-time interval beeping which notifies the motor stop and 30 seconds later the beeping stops. However, do not wait until the motor stops (or alarm beep changes to a short-time beeping), and instead close the inlet valve of the pump and the low pressure side valve of manifold.

Check that the pump is turned off, remove the battery, and charge it or replace it with a spare battery.

• Refer to the following table for the battery operation times.

Operation times (guideline)

• After finishing work, remove the battery and attach the supplied cover.

Transport and storage
