The tool may be damaged. Adjusting the fastening torque (Fig. 7) The fastening torque can be adjusted in 18 steps by turning the adjusting ring so that its graduations are aligned with the pointer on the tool body. The fastening torque is minimum when the number 1 is aligned with the pointer, and maximum when the A marking is aligned with the pointer. The clutch will slip at various torque levels when set at the number 1 to 5. The clutch is designed not to slip at the A marking. Before actual operation, drive a trial screw into your material or a piece of duplicate material to determine which torque level is required for a particular application. NOTE: • The adjusting ring does not lock when the pointer is positioned only half-way between the graduations. • Do not operate the tool with the adjusting ring set between the number 5 and the A marking. The tool may be damaged. Screwdriving operation (Fig. 8) Screwdriving operation (Fig. 8) NOTE: • Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged. • When driving wood screws, predrill pilot holes to make driving easier and to prevent splitting of the workpiece. See the chart below. Nominal diameter of wood screw (mm) Recommended size of pilot hole (mm) 3.1 2.0 – 2.2 3.5 2.2 – 2.5 3.8 2.5 – 2.8 4.5 2.9 – 3.2 4.8 3.1 – 3.4 5.1 3.3 – 3.6 5.5 3.7 – 3.9 5.8 4.0 – 4.2 6.1 4.2 – 4.4 • If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. Drilling operation First, turn the adjusting ring so that the pointer on the tool body points to the A marking. Then proceed as follows. • Drilling in wood When drilling in wood, best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece. • Drilling in metal To prevent the bit from slipping when starting a hole, make an indentation with a centerpunch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling. Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry. CAUTION: • Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool. • There is a tremendous force exerted on the tool/bit at the time of hole breakthrough. Hold the tool firmly and exert care when the bit begins to break through the workpiece. • A stuck bit can be removed simply by setting the reversing switch to reverse rotation in order to back out. However, the tool may back out abruptly if you do not hold it firmly. • Always secure small workpieces in a vise or similar hold-down device. • If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery. MAINTENANCE CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Replacement of carbon brushes (Fig. 9 & 10) Replace carbon brushes when they are worn down to the limit mark. Both identical carbon brushes should be replaced at the same time. To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Center. ACCESSORIES CAUTION: • These accessories or attachments are recommended for use with your Makita tool specified in this manual. The use of any other accessories or attachments might present a risk of injury to persons. Only use accessory or attachment for its stated purpose. If ...
