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 360

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 span-

ner 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.

WARNING

Do not exceed number of turns indicated on

serial plate.  Over-tensioning can cause a 

broken spring, sheared shaft or other damage.

INSTALLATION and MAINTENANCE INSTRUCTIONS

SZ-16 DIRECT DRIVE HAZARDOUS DUTY 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 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.

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.

CABLE INSTALLATION & REMOVAL

Use the procedure detailed on HAZARDOUS DUTY CABLE
REEL SEALING INSTRUCTIONS (bulletin 039789) which
comes with sealing kit (available separately).

CABLE REMOVAL

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 power to reel.  
3.  Remove collector cover and gasket.  
4.  Disconnect electric leads to and from collector.
5.  Follow Steps 3–9, REMOVING OLD CABLE, 

on bulletin 039789.

Carefuly read and follow instructions 

supplied with separate sealing kit as well as 

instructions for sealing compound. Failure to 

properly follow those instructions could result in

damage to equipment, personal injury or death.

CAUTION

Always open all breakers and disconnect electrical

power to reel. Failure to turn off electrical power

could lead to serious injury or death.
