Battery BL1430A is equipped with the battery remaining capacity indicator.

Checking the remaining battery capacity

Fig.2

When charging
When the charging begins, the first (far left) indicating lamp begins to flicker. Then, as charging proceeds, the other lamps light, one after the other, to indicate the battery capacity.

When using
When the tool is switched on, the lamps will light to indicate the remaining battery capacity. When the tool is switched off, the light goes out after approx. 5 seconds. When the tool is used with the battery that has not been used for a long time and is switched on, no lamps may light up at all. Use Makita refreshing adapter to refresh the battery.

NOTE: Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged.

Limits of fastening capacity

Use the tool within the range of the revolution angle up to 360 ﾟ. If you use the tool beyond the upper limit of this range, the clutch does not work. And the tool cannot deliver enough fastening torque (LED indicator flickers in red and green alternatively).

NOTE:

• The revolution angle means the angle which a screw/bolt revolves when the tool attains to 100% from 50% of desired torque.
• Use of a low temperature conditioned battery cartridge may sometimes give warning for battery cartridge capacity by warning lamp and beeper which makes the tool stop immediately. In this case, the fastening capacity may be inferior to the specification on this manual even if a charged battery cartridge is used.

MAINTENANCE

• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
