Operation
1. Check reel for correct operation by slowly
pulling out the hose.
A “clicking” noise will
be heard every half revolution of the drum.
2. To latch: the reel, pull out the hose and
allow it to retract after hearing the first,
second, or third “click”.
3. To unlatch: slowly pull out the hose until the
“clicking” noise stops, and then let the hose
retract until the hose stop rests against the
hose guide.
WARNING
Do not allow hose to retract without
restraining recoil speed. Never let go of the
hose when rewinding. Failure to comply
may result in severe injury.
4. Periodically check the hose condition for
wear or damage, and check the swivel fitting
for leakage.

1. Pull out approximately 6 feet, or 2 meters of
hose and allow the drum to latch.

drum to increase tension or un-wrap hose
one time from drum to decrease tension.
