Reel Operation
Reel Lockup
Caution
Do not remove the hose completely from the reel
to rapidly. Too much force can cause the reel to
over-run, latch, and lockup. If this occurs, the reel
cannot be extended to release the latch mecha-
nism.
Should the reel lockup, it will be necessary to have an
assistant maintain tension on the hose while the latching
mechanism is manually released.
Indications
Reel does not latch
Reel does not retract
Reel retracts partially
Reel does not unlatch
after maximum length
of hose is removed

WARNING
The reel is under maximum Spring tension.
Personal injury can occur.
1. Grip the Sheave Assembly securely with gloved hands.
2. Turn the Sheave Assembly in the direction just enough
that allows Latch Pawl Assembly (32) to be free of
tension from the Ratchet.
• This direction further increases tension on the Power
Spring.
3. While maintaining the position of the Sheave assembly
with one hand, move the Latch Pawl Assembly away
from the Ratchet Assembly.
• Use a screwdriver or other suitable tool.
4. Instruct the assistant to allow the hose to retract slowly
onto the Sheave Assembly.
