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
► Fig.3:
1. Indicator lamps
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for few seconds.

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will brink when
the battery protection system works.

OPERATION
The pump does not contain oil when newly purchased.
Refer to "Adding oil" and add oil.
WARNING:
condition without oil added will damage the pump.
In addition, the oil tank will become hot and may result
in burns or other accidents.

1. Oil fill/Exhaust cap
2. Level line
1. Remove the oil fill/exhaust cap and add the supplied
oil via the filler port.
NOTICE:
Always use Makita genuine oil in order to
maintain pump performance.
2. Add oil until the oil level is between the upper and
lower level lines of the sight glass.
NOTICE:
The oil level is important. Operating the
pump in the condition with the oil level not between the
upper and lower level lines may result in malfunction.
Checking performance

2. Intake port
3. Vacuum pump
1. Connect the low side valve of the manifold and the
intake port of the pump with a charging hose.
2. Close the low side valve of the manifold.
3. 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.
4. Turn the pump off.
