And then, remove the screw by turning clockwise. If it is difficult to unscrew, employ impact driver. See Fig. 1. ( 2 ) Attach hex wrench to the drill chuck. Select the working mode as follows. * Drill mode * Low speed mode * Rotating direction : Clockwise See Fig. 2. Speed change lever : Low speed Hex wrench Turn the screw clockwise for removing. Adjust ring : Drill mode R/L Change lever : clockwise-rotation. Fig. 1 Fig. 2 ( 3 ) Hold the machine on the working table firmly, turn drill chuck clockwise by striking the inserted hex wrench with plastic hammer. see Fig. 3. Then, drill chuck can be removed from the machine. Fig. 3 < 2 >Disassembling gear assembly and motor ( 1 ) After removing drill chuck as illustrated in Fig. 1, Fig. 2 and Fig. 3, separate housing L from housing R, by unscrewing 8 pcs. of pan head screws. See Fig. 4. Fig. 4 Repair P3/6 ( 2 ) Remove gear assembly and motor from housing R by lifting up change ring, gear assembly and motor at a time. And remove High / Low speed change lever from gear assembly. See Fig. 5. Lift up these parts at a time without separating. Change ring Gear assembly DC Motor High / Low speed change lever Compression springs 4 Be careful, not to lose compression springs 4 when removing. Fig. 5 ( 3 ) By turning motor bracket anti-clockwise remove motor from gear assembly. And remove motor bracket from motor by unscrewing 2 pcs. of pan head screws. Then, motor (old one) can be replaced with new one. See Fig. 6. Pan head screws Gear assembly Motor bracket Motor bracket Motor Disconnect from switch terminal. Fig. 6 < 3 > Assembling gear assembly and motor ( 1 ) Mount motor bracket to motor by fastening with pan head screws. Then, mount the motor to gear assembly and turn motor bracket clockwise for securing motor to gear assembly. See Fig. 7. Pan head screws Turn motor bracket clockwise. Motor bracket Fig. 7 Connect with switch terminal. P4/6 Repair ( 2 ) Mount the gear assembly and motor to housing R with aligning the bosses of motor bracket and gear assembly with the boss-acceptances of housing R, See Fig. 8. ( 3 ) Mount housing L and secure it with 8 pcs. of pan head screws. See Fig. 9. < Note > High / Low speed change lever has to be pushed to any of High or Low mode side, when mounting gear assembly and motor. Boss of gear assembly Boss of motor bracket Boss-acceptance Boss-acceptance Fig. 8 Fig. 9 < 4 > Assembling High / Low speed change lever Mount compression springs 4 to High / Low seed change lever. And mount the H / L speed change lever to lever holder. See Fig. 10.
