INSTALLATION and MAINTENANCE INSTRUCTIONS
MMD-32 DIRECT DRIVE ELECTRIC CABLE REELS
All units are provided with right hand rotation unless otherwise
specified. This means that cable is pulled off spool top left or
bottom right (spool rotates clockwise to wind cable) when
viewing spring end of reel. See diagram on parts page.
MAINTENANCE
Periodically: A. Use compressed air to clean collector
assembly and inside of collector housing. Inspect collector
assembly for brush wear and pitted slip rings.
B. Inspect cable for wear and check mounting bolts and
Clock-type springs provide power for automatic cable take-up.
Spring must be pretensioned at time of installation to
insure that tension is applied to cable at all times. A tension
adjustment spanner wrench is provided with each reel.
other hardware for tightness.
C. Check for broken springs
by pulling about 2/3 cable off
reel and observing “Broken
Spring Indicators” on sides of
spring canisters. See Fig. 3.
NOTE: Bearings and springs
are prelubricated and require
no periodic maintenance.

Some reels with large or multiple springs are equipped with
a ratcheted adjustment wrench. Follow separate instruc-
tions for its use. Failure to use ratcheted wrench, on reels
so equipped, could result in serious personal injury.

WARNING
WARNING
Do not attempt to relieve spring tension using span-
ner wrench. Doing so may result in personal injury.
Do not attempt to remove spring from its housing. Clock-
type springs can be dangerous to handle. Removal of
spring from housing could result in personal injury.
INSTALLATION
1. Insure that machinery to be serviced by reel is at position
closest to reel.
2. Securely mount reel in desired position using 3/8"(M10)
bolts. Be sure spool is aligned with cable run.
3. Position optional cable guide, if reel is so equipped.
See CABLE INSTALLATION DRAWING.
The unique SAFETYCHANGE® spring motor consists of a
spring and hub sealed within a housing. A replacement spring
is supplied sealed in its housing and the old unit should be dis-
carded completely.
1. Turn off all electric power.
2. Disconnect cable from machine junction box.
3. Wind all cable onto reel to relieve all spring tension.
4. Remove inspection cover from face of spring housing.
5. Rotate spool clockwise and observe inner shaft. Shaft
should rotate clockwise and hub (with spring attached)
should remain stationary.
4. Connect free end of cable to junction box on machine or
adjust cable stop so that desired length of cable
extends from reel.
5. Remove ratchet wrench andcover plate on spring housing
to expose shaft and spring hub. (Fig 1).
6. Reinstall ratchet wrench (Fig 2). Use long handled wrench
to rotate arbor drive counterclockwise (for standard rotation).
Number of 360O turns should match last digit in model
number on serial plate. If model number includes an “R”,
reel is reverse rotation and wrench must be rotated
clockwise. (See EXPLANATION on parts list page.)
NOTE: Do not attempt to remove spring if resistance
is met or hub tends to rotate with shaft.
Continue to rotate spool and strike end of shaft
several sharp blows with a lead hammer or rubber mallet
until shaft rotates freely and hub remains stationary.
6. Remove (4) nuts which secure spring motor(s) to frame.
7. Slide spring motor(s) off shaft and discard.

AND GASKET
RATCHET WRENCH
(ADJUSTING
NOTE: On multi-spring reels, be sure to remove and save
dowel pins which connect one spring hub with another. Also
remove snap rings on shaft between reel housings.
8. Install replacement spring motor(s), pawls and pawl springs.
NOTE: Pawl springs must be located between the pawls
and the deepest section of the shaft grooves. Make sure
that pawls and pawl springs are inserted flush with ends of
shaft and hub or they may rub against inspection cover.

CABLE REMOVAL
2. Feed one end of the cable through water-tight connector on
the main shaft inside the spool and into the slip ring side.
(See drawing below).
Use the following procedure to remove worn or damaged cable
from reel prior to installation of new cable.
NOTE: This may require that jacket of cable be stripped
to allow conductors to pass through shaft.
CAUTION
3. Connect individual conductors to appropriate rings on
collector using crimp fitting or similar connection method.
4. Tighten water-tight connector and U-bolt provided on
drum wrapper segments. Do not over-tighten.
5. Wind the cable onto the reel spool by hand rotating
spool in direction it turns free of spring tension.
6. Connect free end of cable to machine junction box.
7. Pretension reel and complete installation as
previously described.
Failure to relieve all spring tension prior to removing
cable could result in damage to equipment or personal
injury. Follow instructions carefully.
1. Move machine serviced by reel to a position closest to
reel. Springs will still be under pre-tension at this point.
2. Turn off all electric power.
3. Lock spool to prevent turning using either a spool lock
mechanism or by tying off.
4. Disconnect cable from machine junction box.
5. Grip spool by hand and carefully release spool lock or
tie. Slowly unwind remaining tension.
6. Again lock or tie spool to prevent rotation.
7. Remove cable from spool. Loosen U-bolt and water-tight
connector and disconnect conductors from slip ring.
8. Install new cable following instruction at right.
COLLECTOR REPLACEMENT
1. Turn off all power to reel.
2. Remove collector cover and gasket.
3. Disconnect electric leads to and from collector.
4. Remove drive stud bolt from bearing housing.
5. Remove button plug from hole in side of housing. Insert
long 1/8” Allen wrench through hole and loosen two set
screws in collector locking collar Set screws are at 90O
to one another..
NOTE: Older reels may have lock screws which must be
removed to reach set screws holding collector to shaft.
6. Slide collector off shaft.
CABLE INSTALLATION
Use the following procedure to replace cable or if reel was
ordered without cable. Refer to CABLE INSTALLATION
REFERENCE DRAWING, below.
1. Unspool new cable from shipping spool and lay out
to eliminate twist.
7. Install new collector by reversing above steps.
NOTE: This step is not essential, but will aid in winding
operation of the reel and prolong cable life.
