General Instructions
TENSION ADJUSTMENT
CAUTION: Always leave at least 1-2 turns between full extension and when the
spring is wound tight. If entire hose cannot be pulled out, decrease tension until
full extension is possible. Failure to test for adequate spring revolutions can
cause damage to reel. Hazards or unsafe practices may result in minor personal
injury or product or property damage.
• Reels shipped with hose are
pre-tensioned at factory. Reels
shipped without hose are pre-
tensioned after installing hose,
but before making fi nal hose
or inlet connections.
• (Fig. 8) To pre-tension hose
reel, pull hose out to allow one
full wrap of hose to be looped back over drum assembly. Hold drum from turning by
engaging ratchet (fi g.6). and loop hose back on drum. Repeat until desired tension
is achieved. After tension is set, pull out hose. If full hose extension is not possible,
remove pre-tension turns as needed by reversing process.
Service
CAUTION: Remove all tension before servicing. Hazards or unsafe practices may
result in minor personal injury, product or property damage.
CAUTION: Do not utilize chemicals in the hose &/or the reel. Chemicals can cause
premature failure of the hose &/or the seals.
WARNING: Before performing any service, always disconnect and lock out com-
pressed air or fl uid, and remove all spring tension. Hazards or unsafe practices
could result in severe personal injury or death.
ENCLOSED HOSE REELS
• Enclosed hose reels require additional steps
to remove outer and middle covers (fi g 9.1)
before performing service. Cover is removed
by loosening (2) 10 mm nuts. Reinstall
with middle cover edge as shown (fi g 9.2).
HOSE INSTALLATION AND REPLACEMENT
• Remove all tension from reel (see Tension
Adjustment). Remove hose-stop, unwind hose from
reel, remove strain-relief (8mm nut) and unscrew
hose from its connection point (depending on model,
swivel tee or metal tube assembly). Feed new hose
through roller guide and through slot in fl ange
(except on B-7102). Reattach hose to its connection (use thread sealant or Tefl on tape
for male threaded hose fi ttings; the metal tube assembly on B-7102 does not require
thread sealant). Reattach strain relief clamp, wind onto drum assembly and re-tension
reel.
