• Ensure that only a qualified electrician installs/
services this equipment.

• Ensure that power supply voltage does not exceed
maximum voltage rating of reel.

• Ensure that reel is properly installed before
connecting to power supply.

• All cord reels with flying leads must be hard wired to
ensure proper function.

• Ensure that all electrical power is removed from reel
before servicing.

• A high-tension spring assembly is contained within
the reel. Exercise extreme caution.

• Check for frayed and/or broken wires before each
use. Pull electrical cord from reel by grasping the
electrical cord itself, not the work device.

• If an electrical malfunction should occur, remove
power from reel immediately.

• Ensure that reel, electrical cord and equipment
being serviced are properly grounded. Use an
ohmmeter to check ground continuity.

• If reel ceases to unwind or rewind, remove power
immediately. Do not pull or jerk on electrical cord!

• Treat and respect the reel as any other piece of
machinery, observing all common safety practices.

INSTALLATION

MOUNTING

CAUTION! Maximum installation height is 16
feet. Do not exceed this distance. Ensure that
only a qualified electrician installs/services this
equipment.

TROUBLESHOOTING

Troubleshooting of the reel consists of isolating a
problem to a defective electrical cord/work device,
brush holder/brushes, or collector assembly. Refer any
other discrepancies only to Uline Customer Service at

1-800-295-5510.

WARNING! The following procedure directs
the technician to take voltage measurements.
Remember, even low voltage is dangerous and
can cause personal injury or death. Exercise
extreme caution! Ensure that only a qualified
electrician installs/services this equipment.

1. Unpack and inspect reel for damage. Turn by
hand to check for smooth operation. Check for
completeness.

2. Configure reel for top or side-wind or bottom-wind
electrical cord dispensing by removing bolts (1)
and securing guide arm bracket (2). Determine new
guide arm location and remove corresponding
bolts. Position guide arm bracket to reel and
replace bolts. (See Figure 1)

3. Position reel on floor, wall or ceiling. Secure into place,
using four (customer supplied) screws or bolts (3).
(See Figure 1)

ADJUSTMENTS – SPRING TENSION

If necessary, adjust spring tension on reel by adding or
removing wraps of electrical cord from spool, one wrap
at a time, until desired tension is obtained. Add wraps to

increase tension. Remove wraps to decrease tension.

WARNING! When adding wraps of electrical
cord, be careful not to exceed the winding
mechanism’s spring capacity. Add just enough
wraps of cord to achieve the desired tension.
Damage to the winding mechanism will result
if spring is over-tensioned. Always be aware
of spring tension on reel. Exercise extreme
caution.

1. Ensure that tool or fixture connected to work device
is in good working order. If it is, proceed to step 2.

2. Remove power from reel.

3. Remove access cover (1). (See Figure 2)

4. Reapply power to reel.

5. Check for correct voltage (120 V AC) at terminal strip (2).
(See Figure 2) If voltage reading is correct, replace output
electrical cord/work device (refer to Service Instructions on
page 3). If voltage reading is incorrect, proceed to step 6.

6. Remove power from reel.

7. Using ohmmeter, check continuity of input electrical
cord. If cord checks good, proceed to step 8. If
cord is faulty, replace it (see page 3).

8. Remove brush holder/brushes from reel and inspect
(see page 3). Replace defective components then
proceed to step 9.

9. Reapply power to reel.

10. Check for correct voltage (120 V AC) at terminal
strip (2). If voltage reading is still incorrect, replace
defective collector assembly (see page 3).

11. Replace access cover (1).

Maintain reel by following the instructions given below.
Refer all other repairs, other than those listed, to Uline
Customer Service at 1-800-295-5510. Failure to do so
can result in personal injury and/or equipment damage
and may void the warranty.

WARNING! Remove power from reel before
performing any of the following procedures.

REPLACING THE OUTPUT ELECTRICAL CORD

WARNING! Select output cable in accordance
with power requirement of apparatus to be
supplied. Ensure that application does not
exceed electrical rating of reel. Use extreme
caution, reel under tension. Avoid releasing
latch mechanism.

REPLACING THE INPUT ELECTRICAL CORD

WARNING! Use only 12/3 or 16/3 cable for input
wiring. Ensure that applicatoin does not exceed

electrical rating of reel. All cord reels with GFCI

receptacles must be hard wired into the electrical

circuit. Use of 2 or 3 prong plugs may cause a

potential malfunction of the GFCI receptacle

1. Remove wire nuts (15) securing input electrical cord
to collector assembly (13).

2. Remove 90 degree elbow (9).

3. Remove input electrical cord.

4. Remove 11" of outer jacket from replacement input
electrical cord (input electrical cord wires must protrude
a minimum of 6" from center of collector assembly).

5. Install replacement input electrical cord by reversing
steps 1 through 3.

6. Replace access cover (1).

REPLACING THE BRUSH HOLDER/BRUSHES

1. At terminal strip (10), remove wires connecting
brushes (11) to terminal strip.

2. Remove lock nuts (3) securing brush holder (6) to
reel. Relocate cable clamp temporarily and remove
brush holder.

3. Remove brushes (4) from brush holder (6).

4. Install replacement brush holder/brushes by
reversing steps 1 through 3. Upon completion
of installation, adjust brush-to-ring alignment by
loosening nuts (5) and sliding finger assembly (2).

REPLACING THE COLLECTOR ASSEMBLY

1. Remove wire nuts (15) securing input electrical cord

1. Pull output electrical cord from reel until fully
extended, then latch.

See Figure 3 for the following steps:

2. Remove output electrical bumper stop (7).

3. Disconnect output electrical cord/work device (12)
at terminal strip (10).

4. Remove strain relief (8). Remove output electrical
cord/work device.

5. Install replacement electrical cord/work device by
reversing steps 2 through 4.

6. Release latch and rewind electrical cord on reel.

7. Replace access cover (1).
