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
O
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.

SZ-18 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
