4. Open the inlet valve.

5. Turn the pump on. If the pressure of the manifold

indicates a vacuum of -0.09 to -0.1 MPa within

30 seconds, the pump is operating properly.

6. Turn the pump off.

Operation

► Fig.7:

1. Vacuum pump

2. Intake shut-off valve

3. Charging hose

(yellow)

4. Manifold

5. Low side valve

6. Low pressure gauge

7. High side valve

8. Charging hose (blue)

9. Service port

(Low pressure side)

10. Outdoor unit

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 battery to the pump. (See “Installing

or removing battery cartridge” for the installation

method.)

4. Turn the pump on. The LED lamp (green) lights up.

5. Open the intake shut-off valve of the pump and the

low side valve of the manifold.

WARNING: The pump becomes hot during

operation and immediately after stopping. Do not

touch the 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.

6. When the specied vacuum (refer to the manual

provided by the air conditioner manufacturer) is

reached, close the low side valve of the manifold.

7. Close the intake shut-off valve and 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 noties 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)

Battery Operation times

BL1860B 75 min

BL1850 / BL1850B 50 min

BL1840 / BL1840B 40 min

BL1830 / BL1830B 30 min

• After nishing work, remove the battery and attach

the supplied cover.

NOTICE: When transporting, operating and

storing the pump, never place it on its side or

upside down. This may cause oil leakage from the

oil ller/vent cap.

Transport and storage

• Always drain your vacuum pump of all uids before

shipping to prevent the damage of the container.

• Always cover the intake port with cap to keep any

dust from entering the pump.

• Be sure that the pump is kept in a horizontal position.

• The pump is stored in indoor ambient temperature

5°C – 40°C .

MAINTENANCE

CAUTION: Always be sure that the pump is

switched off and the battery cartridge is removed

before attempting to perform inspection or

maintenance.

NOTICE: Never use gasoline, benzine, thinner,

alcohol or the like. Discoloration, deformation or

cracks may result.

To maintain product SAFETY and RELIABILITY,

repairs, any other maintenance or adjustment should

be performed by Makita Authorized or Factory Service

Centers, always using Makita replacement parts.

Stop the pump:

To make pump life longer and smooth start-up, these

procedures to shut off pump should be followed.

1. Close the manifold valve between the pump and the

system.

2. Remove the hose from the pump inlet.

Cover the inlet port opening to prevent any contamination

or foreign particles from entering the port.

Checking the oil

► Fig.8:

1. Level line 2. Sight glass

• Always check the oil level and condition

(deterioration, etc.) before using the pump.

NOTE: Add oil until the oil level is between the upper

and lower level lines of the sight glass.
