SW3: Refer to Detail 3-4D and mount the
120/240 switch at SW3. Use two 6-32 x 1/4"
black screws and be sure to position the switch
lugs with the jumper wire as shown in the Pic-
torial.

SW2: In a similar manner. mount the
NOR/LOW switch at SW2. Be sure the letters
NOR and LOW are right side up.

Refer to Detail 3-4E and mount the shorter arm
of an angle bracket at L as shown. Use a 4-40 x
1/4" black screw, 3 #4 lockwasher, and a 4-40
nut as shown.

In a similar manner. mount another angle
bracket at M.

Refer to the inset drawing on Detail 3-4F. posi-
tion a large hole Spade bolt as shown, and
mount the spade bolt onto one and of the
capacitor strap as shown. Use a 632 x 1/4
screw. 3 #6 lockwasher, and a 6-32 nut.

In a similar manner. mount another large hole
spade bolt onto the other end of the capacitor
strap.

to the left reader bracket. Use a #6 x 3/8 flat
head. sheet metal screw at S and a #6 x 1/4"
sheet metal screw at T.

[ ) Refer to Detail 3-513 and start a 6-32 X 1/8"
setscrew into a brass collar. Then slide the col-
lar onto a sprocket as shown but DO NOT
tighten the setscrew.

( ] Refer to Detail 3-5F and position the stepper
motor so the wires come out the bottom rear as
shown,

[ ) M1: Again refer to Detail 3-5F and mount the
stepper motor as follows:

Refer to Detail 3-1313. loosen screw AB, and
adjust the roller mounting bracket for the 1/64"
to 1/32" clearance as shown in the inset draw-
ing. Then securely tighten the bracket screw.
Firmly hold the bracket in place as you tighten
the screw to prevent it from turning and off
centering" the detent roller on the detent. Be
sure the dog spring is centered vertically in the
ratchet gear hole as shown in the inset drawing.

Again, refer to Detail 3-1315 and manually de-
press the solenoid plunger. The ratchet will
advance one step. While you hold the plunger
in. adjust the solenoid again for a 1/54" to 1/32"
clearancein this new position. Then tighten the
solenoid mounting screws.

Manually operate the solenoid several times.
The plunger should freely return to its resting
position. If it does not, loosen the ratchet gear
setscrews, move the gear away from the dog
plateslightly.andthen retightenthesetscrews.

Connect the free end of the red wire coming
from solenoid L9 lug 2 to solenoid L10 lug 2
(NS).

Connect the free end of the red wire coming
from solenoid L3 lug 2 to solenoid L10 lug 2
{NS}.

D26: Connect the lead at the banded end of the
1N4002 diode (#57-65] to solenoid L10 lug 2
[5-3]. Position the diode as shown in Pictorial
3-13.

Connect the main circuit board whiteblack
wire to solenoid L10 lug 1 (NS).

1327: Connect the lead at the banded end of the
1N4746A diode [#56-605) to solenoid L10 lug 1
(5-2].

Connect together the free leads of the diodes
and solder the connection.

Position all wires away from the solenoids and
solenoid brackets so that vibration and solenoid
action will not wear on the wire insulation.
