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:
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.
CAUTION:
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.
NOTE: A minimum 2 pre-tension turns is required. Additional turns can 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 full one turn remains.
Reels shipped with cable end
attachments (handlamps, plugs,
etc.) are pre-tensioned at
factory. All other reels require
pretensioning 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 pretension 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 pretension reel may result in insufficient tension to
retract and may shorten spring life.
SERVICE
BULB REPLACEMENT--model 228BH
CAUTION:
Always check for shorts and continuity before turning on electrical power. Hazards or
unsafe practices MAY result in minor personal injury or product or property damage.
Remove guard on hand lamp by removing screws on base of guard.
NOTE: Use a 75-watt or smaller bulb. A rough service bulb is recommended.
MAINSPRING
WARNING:
Always disconnect electrical power before dismantling any part of the reel. Fuse size
must not be 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.
WARNING:
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.
WARNING:
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.
