INSTALLATION and MAINTENANCE INSTRUCTIONS  
SHO TWIN SPRING STACK ELECTRIC CABLE REELS  
MAINTENANCE  
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.  
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  
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.  
“IN” with 2/3

BROKEN SPRING  
INDICATORS  
check mounting bolts and other  
hardware for tightness.  
C. Check for broken springs by  
pulling about 2/3 cable off reel  
“OUT” with 2/3  
cable off reel–  
SPRING  
BROKEN  
and observing “Broken Spring  
WARNING  
Indicators” on sides of spring  
canisters. See Fig. 3.  
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.  
NOTE: Bearings and springs  
Figure 3  
are prelubricated and require no  
periodic maintenance.  
WARNING  
WARNING  
Do not attempt to relieve spring tension using spanner  
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  
SPRING REPLACEMENT  
1. Insure that machinery to be serviced by reel is at position  
closest to reel.  
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.  
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.  
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.  
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: 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.  
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.

CAUTION  
10. Connect free end of cable to junction box on machine or adjust  
cord stop so that desired length of cord extends from reel.  
Do not exceed number of turns indicated on  
serial plate. Over-tensioning can cause a  
broken spring, sheared shaft or other damage.  
11. Tension spring with spanner wrench. Refer to  
INSTALLATION section.  
12. Replace inspection cover.

NOTE: SHO Twin Spring Reels have five to eight springs with a maximum of four in each  
stack. The sum of the two stub shafts (item 11) used on each reel equals the total number  
of springs. Example: An SHO1007 reel (shown above would have one 1003 and one 1004  
stub shaft.  
 
CABLE REMOVAL  
Use the following procedure to remove worn or damaged  
cable from reel prior to installation of new cable.  
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).  
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.  
Failure to relieve all spring tension prior to removing  
cable could result in damage to equipment or  
personal injury. Follow instructions carefully  
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 rotation spool  
in direction it tuns free of spring tension.  
6.Connect free end of cable to machine junction box.  
7.Pretension reel and complete installation as previously  
described.  
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 wither 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.  
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 pipe plug from hole in side of housing. Insert  
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.  
8.Install new cable following instruction at right.  
CABLE INSTALLATION  
Use the following procedure to replace cable or if reel was  
ordered without cable. Refer to CABLE INSTALLATION  
REFERENCE DRAWING, below.  
6.Slide collector off shaft.  
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.
