All reels mounted over head should have a secondary support chain to protect personnel in case of structure or mounting component
failure. Attach one end of secondary support chain or cable to secondary support point on reel. Attach other end of secondary support
chain or cable to a support component other than that which supports the reel. The chain or cable should be as short as possible allowing
reel to drop no more than 6 to 12 inches if the primary connection is released. A secondary support is offered as an accessory item.
PIVOT BASE
If optional pivot base is used, four roller cable guide reel will align reel to direction of cable pull.
WIRING
NOTE: The green wire has been grounded to the frame of
the reel and spool, and cannot be used as a power
conductor.
A convenient one inch pipe thread opening has been provided at the
bottom of the enclosure in base for connecting standard water tight
cable connectors or conduit fitting--fittings not supplied. Individual
power connections are made to the collector ring bus wires inside
the junction box enclosure in base using commercially available
twist on wire connectors or compression splices.

WIRING SUPPLY CONNECTION
NOTE: See “Service, Working Cable Replacement/Installation” if cable needs to be installed.
ROLLER GUIDE AND SHEAVES
Cable must exit guide in-line with pulling direction. If not, rotate guide arm as needed.
The cable guide position is set by rotating spring pocket assembly. Loosen the three
clamps holding spring pocket assembly in place by unscrewing the three hex head
bolts. Unless required, do not completely remove bolts or clamps. Reposition guide
as required, making sure clamps straddle ribs on outside diameter of spring pocket
assembly and retighten hex head bolts.
Sheaves are used to bend cable around corners. Typical minimum bend radius of
the sheave should be about 7.5 x cable diameter. Requirements can vary depending
on cable manufacturer specifications. Sheaves should have flat surfaces for cable to
ride on. The movement of cable through a sheave should be in the same plane as the
cable spool. Changing planes can greatly reduce cable life.
CABLE WINDING
There are many types of cable that may be installed on your cable reel depending on application. Select the cable most appropriate for
your application requirements. Many cables come from the factory with a wax-like film that can encourage uneven wrapping. At initial set
up it is common to use a dry lubricant (talc powder), or silicone based grease to encourage more even winding. Also critical to proper
winding is the adequate setting of “Spring Tension”. See appropriate section. In some cases sheaves and unanticipated application
features can require more tension than offered with standard reels. Contact factory for application assistance.

OPERATION
RATCHET LOCK
All models are supplied with a ratchet lock that works in any position. If ratchet lock is not
required--constant tension--, move spring clip and spring to adjacent cable guide screw.
SPRING TENSION
CAUTION:
CAUTION:
NOTE: A minimum of 2 pre-tension turns is required. Additional turns can be added as long as one unused spring turn
remains when cable is fully extended. If entire cable cannot be pulled out, decrease spring tension until a full one turn
remains.
All reels require pre-tensioning turns to spool assembly before
connecting free end of working cable. Set spring tension by turning
fully wrapped reel through a specific number of revolutions or turns.
Number of pre-tension turns depends on application and desired
tension. A minimum of 2 set up turns is needed for most
applications. Additional tension may be added by repeating
above process. After tension is set, connect cable free end. Failure
to pre-tension reel may result in insufficient tension to retract and
may shorten spring life.
Do not connect working end of cable until the reel is properly pretensioned. Hazards or unsafe
practices MAY result in minor personal injury or product or property damage.
Failure to test for adequate spring revolutions can cause spring damage. Hazards or unsafe practices
MAY result in minor personal injury or product or property damage.

WARNING:
If reel will not develop tension or retract cable, spring assembly may need to be replaced. Remove junction box cover. Disconnect lineinput wires from collector ring bus wires. Also disconnect cable free end and allow spring to unwind completely. Remove screw, shaft
retainer, then pull complete spool assembly with cable from base. Remove cable guide, spring clip, ratchet spring, shoulder bolt and
ratchet pawl from spring pocket assembly. Remove spring pocket assembly from base and replace with new part. To reassemble, reverse
the above procedure making sure the dimple in the shaft retainer is toward the main shaft. Re-tension cable reel as per instructions.

greater than maximum amperage capacity of cable. Remove all spring tension before attempting any
service. Hazards or unsafe practices COULD result in severe personal injury or death.
To prevent personal injury, death or property damage, handle all springs with care. Use suitable
protective gloves for spring handling. Hazards or unsafe practices COULD result in severe personal
injury or death.
To prevent personal injury, death or property damage, hold center of spring down as the hub is pulled
out. If the center is allowed to rise up, the spring may escape from its container. Hazards or unsafe
practices COULD result in severe personal injury or death.

COLLECTOR RING REPLACEMENT
WARNING:
CAUTION:
Disconnect and lock out all power to reel and remove all tension on spring before servicing collector
ring assembly. Hazards or unsafe practices COULD result in severe personal injury or death.
Check continuity and replace all covers before turning on electrical power. Hazards or unsafe
practices MAY result in minor personal injury or product or property damage.
Check placement of brush holder assemblies to make sure terminal locations are centered between
WARNING:
the protruding lobes on the inner and outer drums. Hazards or unsafe practices COULD result in
severe personal injury or death.
NOTE: Check position of cable entry in relationship to studs marked by
“X” in figure. Replace subsequent brush assemblies in clockwise rotation.
To service the collector ring assembly, remove junction box cover and disconnect bus
wires in junction box. Remove cover, if required, and outer drum-half. Unclip brush
assembly from brush studs and remove. Notice position of brush assembly. Remove
all brush assemblies from collector ring. Loosen collector ring set screw and slide
collector ring off main shaft. To reassemble, reverse above procedure. The last brush
assembly--one closest to steel hub on collector ring--must be assembled on brush
studs indicated by the “X” in the figure to the right.
WORKING CABLE REPLACEMENT/INSTALLATION
WARNING:
Disconnect and lock out all power to reel and remove all tension on spring before servicing collector
ring assembly. Hazards or unsafe practices COULD result in severe personal injury or death.
CAUTION:
Check continuity and replace all covers before turning on electrical power. Hazards or unsafe
practices MAY result in minor personal injury or product or property damage.
NOTE: Cable seal is a bellows type seal designed to fit different size cables. Pull out the bellows in one direction and
cut the seal so that the through opening is at least 1/8” diameter smaller than the working cable. Always cut the seal
smaller than required. More of the seal may be cut off if necessary.
This procedure applies to both new installations and for replacement of working cable. To install/replace cable loosen seal cover and
cable seal. Remove cover, if required, and outer drum half. Loosen or remove cable clamp and individual conductors of working cable
from brush assemblies. Pull working cable through opening of inner drum and remove seal cover, and cable seal from old working cable.
Place seal cover and cable seal over replacement cable. To reassemble, reverse the above procedure. Be sure to connect working cable
conductors to the proper brush assembly. Re-tension spring.
