SERVICING INSTRUCTIONS 880M
Assembly/Disassembly for Inspection or Replacement:
1. Remove V belt and guard.
2. Disconnect cables which attach clutch housing to control box.
3. Remove the three screws located approximately 120° apart. When re-
moving last screw, place hand under clutch / brake housin g so that
unit will not fall.
4. Keep clutch/brake housing tilted sli gh ': ly d· Jwllv.·a:-.:: (p ul ley si de do v.'Tl)
to keep the clutch/brake disc in pla ce.
5. Place the clutch/brake housing, pulley side facing upward, on a clean
flat surface. Separate the clutch solenoid from the end bell. Note:
Use caution during disassembly and reassembly to ensure alignment and
inserting of the solenoid electrical connection pins into the mating
socket of the end bell. Slide the clutch and brake discs of the splined
shaft of the end bell. Put the end bell aside and inspect the clutch/
brake discs for wear. If cork surfaces are smooth and if cork on
clutch disc projects beyond the outer metal rim, discs are okay.
6. Clean the surfaces of the face plates with an oiled rag. These
surfaces should be smooth. If you find nicks and gouges on them,
replace the plates.
7. Thoroughly clean the cork faces of the clutch/brake discs using a clean,
dry rag. Apply grease (Quick No. 051.011) in 3-one inch segments every
120°. Spread the grease evenly over the entire cork surfaces.
8. Apply a small amount of grease to the brass splines on which the
clutch/brake discs move. This will assure proper action.
9. Reassemble the clutch/brake discs making sure the rubber "O" rings
(part No. 408.009) and the stop washer (part No. 250.008) are in good
condition. To assure proper operation of the cooling system, make
certain that the vent holes are lined up.
10. Reinstall the clutch/brake discs and housing by reversing the pro-
cedures outlined in sections 3., 2., and 1.
11. Once reinstallation is completed, check the clutch/brake clearance
as outlined

ADJUSTING THE CLUTCH/BRAKE CLEARANCE
1. Remove fan cover (1) by turning counterclockwise.
2. Insert adjusting tool (4) into the bores on fan (2). Exert pressure
on adjusting tool and turn fan until the tool locks into the bores
of adjusting screw (3).
3. With tool locked in place, turn fan (2) clockwise until pulley (6)
has a moderate drag when rotated with the other hand.
4. Rotate adjusting tool (4) and fan (2) 120° counterclockwise
(120° is the distance between cap nuts [5] on the end bell. Re-
quired clutch clearance .5 mm).

Lubrication
To prolong cork facing life and increase smoothness of operation, the
following lubrication should be performed annually:
1. Disassemble clutch/brake assembly
as described on the reverse side.
2. Remove clutch and brake discs.
3. Clean cork surfaces of the discs
and the metal facings of the
flywheel and brake surfaces '..'ith
a clean, lint-free cloth. Note:
Mineral spirits solvent or carbon
tetrachloride can be used on
METAL SURFACES ONLY to speed up
cleaning.
4. Apply 3 segments of Quick grease
(Part No. 051.011) about one
inch long, as shown in the illus-
tration, to the cork surfaces.
Grease
5. Spread grease evenly on both cork surfaces.
6. Install on splined shaft AFTER lightly coating the splines with the
special grease.

Operating Instructions
1. Install a fully wound bobbin in ma-
chine. Set counter to a value of 900 by
holding the reset button in while index-
ing the appropriate digit by pressing the
other three black buttons.
2. Sew the complete bobbin keeping watch
for when the bobbin thread runs out. The
counter will count down one number each
time a garment is completed (counts trim-
mer pulses).
3. Subtract the resulting count from
900 - this figure represents the number
of garments that can be sewn from a full
bobbin. Also subtract a few cycles from
this number to account for any variance
that might occur.
~. Reset the counter digits to the final
count obtained.
5. - When the counter reaches zero the _
bobbin
run-out warning 1 ight wU 1 come
on and the presser foot will not 11ft
when the operator heels back on the trea-
dle. When this happens, press the reset -
button and Install new bobbin.
