Description
Caution
These reels must be ceiling mounted at a
height no greater than 16 feet (4.9 m) from
the floor to comply with the warranty.
Hose reel Models 7234-B and 7235-B are
designed to be mounted to the wall, ceiling, or floor.
They can also mount to truck beds.
The reels mount as a single unit or in banks of as
many as required. Banked reels should be a
minimum of 9 " (23 cm) apart on center. For ease in
reel maintenance, a space of up to 15 " (38 cm) is
recommended. See Figure 6 .
Each model reel is spring-powered and self-
retracting. A latch locks the reel once the required
length of hose is released. A pull releases the latch
and allows the hose to retract onto the reel.
Models 7234-B and 7235-B
Model 7234-B contains a high-pressure swivel
assembly. This swivel is designed to dispense
grease from either 1/4 " or 3/8 " ID two-wire braid

Mount Positions
The reel can mount to either the floor, wall, or ceiling.
The selected mount position influences the position of
the Guide and Roller Assembly as it relates to the Base.
For example, when the reel mounts to the ceiling, the
Guide and Roller Assembly will always be parallel with
the Base. See Figure 5.
When a parallel alignment is dictated, the chosen slots
in the Sheave Assembly must correspond to this
configuration.
The Sheave Assembly contains four sets of slots.
Locate each U-Bolt in the appropriate slot dictated by the
alignment. See Figure 5.
Figure 5 U-Bolt Location on Sheave Assembly for Parallel and Perpendicular Base Alignment
Caution
Failure to follow the recommended slot selection
for the chosen alignment can result in reel lockup.
When the material hose is fully extended from the
Sheave Assembly and the proper slots are chosen, the
latching mechanism will not engage the ratchet. This
prevents reel lockup.
Ceiling Mount
IMPORTANT: It is mandatory that these
reels be ceiling mounted no higher than 16'
(4.9 m) from the floor. Should the existing
ceiling height be greater, mount the reel to a
suspension bracket. See Figure 6.

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.
WARNING
The reel is under maximum Spring tension.
Personal injury can occur.
1. Grip the Sheave Assembly securely with gloved hands.
2. Turn the SheaveAssembly 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.
