After fastening, alwayscheck the torque with a torque wrench.1. When the battery cartridge is discharged almostcompletely, voltage will drop and the fasteningtorque will be reduced.2. Driver bit or socket bitFailure to use the correct size driver bit or socketbit will cause a reduction in the fastening torque.3. Bolt• Even though the torque coefficient and theclass of bolt are the same, the proper fasteningtorque will differ according to the diameter ofbolt.• Even though the diameters of bolts are thesame, the proper fastening torque will differaccording to the torque coefficient, the class ofbolt and the bolt length.4. The manner of holding the tool or the material ofdriving position to be fastened will affect the torque.Using the tool as a hand screwdriver010331Switch off the tool.Move the lock lever to the locked positionTurn the tool.NOTE:• Use the tool with a fastening torque less than 12.5Nm (9ft•lbs).• This use is convenient for checking thescrewdriving.• Do not use the tool for work requiring excessiveforce, such as tightening bolt M10 or bolts greaterthan M10 or removing rusted screws.MAINTENANCECAUTION:• Always be sure that the tool is switched off and thebattery cartridge is removed before attempting toperform inspection or maintenance.• Never use gasoline, benzine, thinner, alcohol or thelike. Discoloration, deformation or cracks mayresult.To maintain product SAFETY and RELIABILITY, repairs,any other maintenance or adjustment should beperformed by Makita Authorized or Factory ServiceCenters, always using Makita replacement parts.
