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.
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.
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.
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 cover plate on spring housing to
expose
shaft and spring hub. (See Figure 1).
6. Insert spanner wrench into holes in spring hub (Fig 2).
Rotate wrench 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: If reel is equipped with ratcheted adjustment
wrench, follow instructions on separate sheet.
NOTE: On reels containing more than one spring, the hubs
are connected at the factory. Therefore, by tightening the
outer spring, the inside spring(s) will be tightened.
7. Remove collector cover and connect individual supply
conductors to collector terminals.
Do not attempt to relieve spring tension using spanner
wrench. Doing so may result in personal injury.
WARNING
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.

INSTALLATION and MAINTENANCE INSTRUCTIONS
SHO TWIN SPRING STACK ELECTRIC CABLE REELS
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 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.
SPRING REPLACEMENT
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 discarded
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.
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.
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 spring 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.
9. Tighten nuts (and extension bolts) securing spring
housing(s) to reel frame.
10. Connect free end of cable to junction box on machine or adjust
cord stop so that desired length of cord extends from reel.
11. Tension spring with spanner wrench. Refer to
INSTALLATION section.
12. Replace inspection cover.
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.

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