(3) Reassembly of housing (A). (B) set
(a) Apply silicone rubber (THREEBOND 1211) to the diagonally shaded areas in Fig. 14 before
mounting the parts to housing (A).
(b) Mount a unit of the hammer assembly, Hammer Case
[7]
, Inner Cover (D)
[25]
(including
the Rotor
[27]
), Controller. Stator Ass'y
[44]
, Dust Cover
[26]
and DC Speed Control Switch
[34]
into housing (A).
(c) Pay attention to the following items in reassembly. (See Fig. 15.)
• Before inserting the Rotor
[27]
into the stator, set the Dust Cover
[26]
between the core
and the fan of the Rotor
[27]
. After inserting the Rotor
[27]
into the stator, fit the protrusion
of the stator in the concave portion of the Dust Cover
[26]
.
• Mount the Hammer Case
[7]
to the housing so that the protrusion (for locking) of the
Hammer Case
[7]
contacts the support hole of the housing as shown in Fig. 15.
• Check that the Hammer Case
[7]
is mounted to the housing properly. If the Hammer Case
[7]
is not fitted in the specified groove of the housing or the rib of Inner Cover (D)
[25]
is
not perpendicular to the rib of the Hammer Case
[7]
, remount the Hammer Case
[7]
properly. Be sure to mount the Hammer Case
[7]
to the housing properly to prevent
slipping off in the axial direction.
(d) After applying silicone rubber (THREEBOND 1211) to housing (A), fit the Strap (Black)
[42]
in the boss as shown in Fig. 16. Apply silicone rubber (THREEBOND 1211) to housing (B)
at the same position as housing (A). Mount the Lock Nut M4 (Black)
[40]
and the Packing
[41]
to Housing (A). (B) Set
[29]
. Then secure housing (B) to it with the nine Tapping
Screws (W/Flange) D4 x 20 (Black)
[30]
. Wipe off silicone rubber (THREEBOND 1211)
protruded from the housing with a cloth. (See Fig. 16.)
