• Inner circumference of the metal inserted in Inner Cover (A) [13]
• Outer circumference of the Pin D5 [24]
• Both surfaces of Washer (C) [20]
• Both surfaces of Washer (B) [10]
Fill 10 grams of Cosmo Molybdenum No. 2 grease in the following part.
• Inside of Gear Cover (A) [9]
• Flat Hd. Screw (A) (Left Hand) M6 x 25 [1] ······························ 4.9 ± 0.5 N•m (50 ± 5 kgf•cm)
• Tapping Screw (W/Flange) D4 x 20 (Black) [43] ························ 2.0 ± 0.5 N•m (20 ± 5 kgf•cm)
• Hex. Socket Hd. Bolt (W/Flange) M5 x 45 [8] ··························· 4.9 ± 1.0 N•m (50 ± 10 kgf•cm)
• Drill Chuck 13VLRB-D [3] ···················································· 34.3 ± 0.49 N•m (350 ± 50 kgf•cm)

On completion of reassembly after repair, measure the insulation resistance and conduct the dielectric
strength test.
Insulation resistance: 7 M or more with a 500 VDC megohm tester
Dielectric strength: 4,000 VAC/minute, with no abnormalities ······ 220 V to 240 V (110 V for UK products)
2,500 VAC/minute, with no abnormalities ······ 110 V to 127 V (except for UK products)
After no-load operation for 30 minutes, the no-load current values should be as follows:
