10-2. Disassembly and Reassembly of the Output Section
(1) Piston Bumper [21] and the related parts
Tools required
3 mm dia. (0.118") roll pin remover
4 mm (0.157") hexagonal bar wrench
8 mm (0.315") spanner
(a) Disassembly (Refer to Fig. 10.)
Extract the Roll Pin D3 x 30 [38] with a roll pin remover.
Remove the Hex. Socket Hd. Bolt M5 x 18 [31] and the four Nylock Hex. Socket Hd. Bolts M5 x 16 [24]
which retain the Nose Ass'y [22], and take off the Nose Ass'y [22], the Magazine Ass'y [63] and connected
parts in a single body. At this time, Plunger (B) [52] and Plunger (B) Spring [51] and Washer M5 [50] may
fall out, so exercise care not to lose it. The Piston Bumper [21] can then be taken out from the lower part of
the main body (Body Ass'y [19]).
(b) Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to the following items:
Ensure that the Piston [9] is properly engaged in the groove of the Guide Plate [25].
Confirm that Plunger (B) [52], Plunger (B) Spring [51] and Washer M5 [50] have not fallen out and become
lost.
Loosely fasten the Nose Ass'y [22] onto Body Ass'y [19] with the four Nylock Hex. Socket Hd. Bolts M5 x 16
[24], and fully tighten the Hex. Socket Hd. Bolts M5 x 18 [31] to specified torque of 85 5 kg
•
cm (6.1 0.4
ft-lb).
Then fully tighten the four Nylock Hex. Socket Hd. Bolts M5 x 16 [24] to specified torque of 85 5 kg•cm
(6.1 0.4 ft-lb).
[CAUTION] Ensure without fail that tightening of bolts is accomplished in the order described
above. If the four Nylock Hex. Socket Hd. Bolts M5 x 16 [24] are fully tightened to
specified torque before tightening the Hex. Socket Hd. Bolt M5 x 18 [31], it will apply
excessive strain on the Magazine Ass'y [63] which will cause deformation of the
magazine ass'y and irregular feeding of nails.
