If the green indicator light is “ON”, the charger is plugged in but the battery pack is not inserted, or the battery pack is fully charged and is being trickle charged, or the battery pack is too hot or cold for fast-charging. The charger will switch to trickle charge, until a suitable temperature is reached, at which time the charger will switch automatically to fast- charging. If the green indicator light is “BLINKING”, the battery pack is being fast-charged. Fast-charging will automatically stop when the battery pack is fully charged. CHARGING BATTERY PACK (1 HOUR CHARGER) Plug charger cord into your standard power outlet. Before inserting battery pack, remove protective cap, then insert battery pack into charger (Fig. 12). The charger’s green indicator will begin to “BLINK”. This indicates that the battery is receiving a fast charge. Fast-charging will automatically stop when the battery pack is fully charged. When the indicator light stops “BLINKING” (and becomes a steady green light) fast charging is complete. When you begin the charging process of the battery pack, a steady green light could also mean the battery pack is too hot or too cold. The purpose of the light is to indicate that the battery pack is fast-charging. It does not indicate the exact point of full charge. The light will stop blinking in less time if the battery pack was not completely discharged. When the battery pack is fully charged, unplug the charger (unless you're charging another battery pack) and slip the battery pack back into the tool handle. !WARNING To prevent fire or injury when batteries are not in tool or charger, always place protective cap onto end of battery pack.

During the operation, hold the tool firmly and exert light, steady pressure. Too much pressure at low speed will stall the tool. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to both tool and bit. DRIVING WITH VARIABLE SPEED The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled. Always hold the machine straight on the bolt to be tightened. The best method to determine the right impacting/tightening duration is by means of a trial. For small screws, the right impacting/tightening duration can be reached in less then 0.5 Sec. Therefore, work with low RPM and switch the machine off immediately when the screw is tight and the impacting sound can be heard. For screwing larger, longer wood screws into hard material, pre-drilling is the best method. TIGHTENING TORQUE The tightening torque depends on the duration of the impacting/tightening action. The largest tightening torque is achieved after approx. 6 to 10 Sec. impacting/ tightening action. The torque build-up depends on the following factors: • Hardness of the bolts/nuts. • Type of washer (disk washer, spring washer, seal). • Hardness of the material to be joined. • Lubricating effect at the surfaces of the junction. This leads to the following application cases: Hard case: The joining of metal to metal with a disk washer. The maximum torque is reached after a relative short impacting/ tightening action. Medium case: The joining of metal to metal where spring ring washer, disk spring washer, stud bolts or bolts/nuts with conical seats are used. Soft case: The joining of e.g. 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.
