metal to wood or insulation material. For middle or soft joining cases, the maximum tightening torque is less as for hard cases. Therefore, a longer impacting/ tightening action is necessary to arrive at the maximum tightening torque. FASTENING WITH SCREWS This procedure shown in (Fig. 13) will enable you to fasten materials together with your tool without stripping, splitting or separating the material. First, clamp the pieces together and drill the first hole 2/3 the diameter of the screw. If the material is soft, drill only 2/3 the proper length. If it is hard, drill the entire length. Second, unclamp the pieces and drill the second hole the same diameter as the screw shank in the first or top piece of wood. Third, if flat head screw is used, countersink the hole to make the screw flush with the surface. Then, simply apply even pressure when driving the screw. The screw shank 2. Drill same diameter as screw shank. 3. Countersink same diameter as screw head. 1. Drill 2/3 diameter and 2/3 of screw length for soft materials, full length for hard materials. Screw Apply a slight even pressure when driving screws. FASTENING WITH SCREWS FIG. 13 -16 BM 2609140358 12-05 12/6/05 3:28 PM Page 17 clearance hole in the first piece allows the screw head to pull the pieces tightly together. RUNNING NUTS AND BOLTS Variable speed control must be used with caution for driving nuts and bolts with socket set attachments. The technique is to start slowly, increasing speed as the nut or bolt runs down. Set the nut or bolt snugly by slowing the tool to a stop. If this procedure is not followed, the tool will have a tendency to torque or twist in your hands when the nut or bolt seats. Maintenance Service NO USER SERVICEABLE PARTS INSIDE. Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Bosch Factory Service Center or Authorized Bosch Service Station. SERVICEMEN: Disconnect tool and/or charger from power source before servicing. !WARNING BATTERIES Be alert for battery packs that are nearing their end of life. If you notice decreased tool performance or significantly shorter running time between charges then it is time to replace the battery pack. Failure to do so can cause the tool to operate improperly or damage the charger. Long term battery storage should be in the discharged state. Battery packs last longer and re-charge better when they are stored discharged. Remember to fully recharge battery packs before using after prolonged storage. TOOL LUBRICATION Your Bosch tool has been properly lubricated and is ready for use. CARBON BRUSHES The brushes and commutator in your tool have been engineered for many hours of dependable service. If your tool runs sporadically, loses power, makes unusual noises or runs at a reduced speed, check the brushes. To continue using the tool in this condition will permanently damage your tool. Check both brushes. Usually the brushes will not wear out simultaneously. If one brush is worn out, replace both brushes. To check brushes: Disconnect battery pack from tool. Rotate brush cap at the rear part of housing counter-clockwise with a coin or screwdriver and remove cap (Fig. 14). BRUSH CAP BRUSH FIG. 14 Lift out the brushes; note which way they face, so that the brushes can be returned to their original position. New brushes can also be inserted turned 180.. Clean the brush holder openings with compressed air or a clean cloth and replace the brushes and brush covers. After replacing brushes the tool should be run at no-load and run it freely at full speed for 2 minutes before using the tool. This will allow the brushes to “seat” properly and will give you more hours of life from each set of brushes. Only genuine Bosch replacement brushes specially designed for your tool should be used. D.C. MOTORS The motor in your tool has been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend it be examined every six months. Only a genuine Bosch replacement motor specially designed for your tool should be used. -17 BM 2609140358 12-05 12/6/05 3:28 PM Page 18 Cleaning To avoid accidents, always disconnect the tool and/or charger from the power supply before cleaning. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air. !WARNING Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through opening. !CAUTION Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia. Accessories !WARNING If an extension cord is necessary, a cord with adequate size conductors that is capable of carrying the current necessary for you...
