LD CD4500 User manual

CD4500/CD5500 BOAT LIFT WINCH
WARNING READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL,
OPERATE OR SERVICE THIS WINCH. FAILURE TO COMPLY WITH INSTRUCTIONS COULD
RESULT IN SERIOUS OR FATAL INJURY. RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE.
ASSEMBLY – The crank wheel and hub for this winch are not made by
Dutton-Lainson Company, so check the following to ensure trouble free
operation. The side of the hub that contacts the brake lining plate must
have a counterbore that is at least 1/8” deep before the threads begin.
Thread the crank wheel onto the drive shaft and make sure the wheel
threads on freely without any binding. Thread the wheel all the way onto
the shaft and ensure the shaft sticks out past the hub by at least 1/16”.
Install the washer and bolt onto the end of the shaft. The winch should
make a clicking noise when the crank wheel is turned clockwise. See
parts drawing for details.
IMPORTANT SAFETY INFORMATION
•This brake winch is built for raising and lowering boat lifts and other
similar applications. It is not to be used as a hoist for lifting, supporting
or transporting people, or for loads over areas where people could be
present.
• Respect this winch. High forces are created when using a winch,
creating potential safety hazards. It should be operated and maintained
in accordance with instructions. Never allow children or anyone who is
not familiar with the operation of the winch to use it. A winch accident
could result in personal injury.
• Check winch for proper operation on each use. Do not use if damaged.
Seek immediate repairs.
• Never exceed rated capacity. Excess load may cause premature failure
and could result in serious personal injury. The CD4500 is rated to pull
2250 lbs. single line and 4500 lbs. double line on the second layer of
cable. The CD5500 is rated to pull 2750 lbs. single line and 5500 lbs.
double line on the second layer of cable. Using more layers of cable
increases the load on the winch.
• Never apply load on winch with cable fully extended. Keep at least
two full turns of cable on the reel. Check cable on every use. Replace
at first sign of kinks, broken wires, deformation or any other damage.
• Secure load properly. When winching operation is complete, do not
depend on winch alone to support load.
WINCH MAINTENANCE – Keep winch in good working order. Damaged
or severely worn parts create unnecessary dangers and could result
in personal injury or property damage. The winch requires periodic
maintenance. The following check should be made at least once annually
and more frequently when the winch is exposed to an environment which
is particularly dirty or wet.
1. Remove all load from the winch so there is slack in the cable. Remove
the top cover from the winch and examine the winch gear train and
brake mechanism for any rust, corrosion, or buildup of debris which
might be present.
2. Inspect links on all roller chains and replace if there are any cracked or
missing rollers. Apply oil to roller chains with a brush or oil can. Oil each
link between the pin and bushing and the link side plates. Apply a drop
of oil at ends of bushings on intermediate sprocket assemblies and to
bushings on primary drive shaft.
CAUTION! Do not grease or oil any of the brake mechanism parts.
3. If needed, remove brake components. Remove the bolt and washer
from the end of the drive shaft and unthread the crank wheel off the
shaft by turning it counterclockwise. Remove the brake cover by
removing the three screws holding the cover to the front base plate. Pull
the ratchet pawl out of engagement with the ratchet wheel and slide the
brake lining plates and ratchet wheel off the drive shaft.
4. Check the ratchet wheel, brake lining plates, crank wheel hub and the
washer on drive shaft assembly for any build up or glaze (shiny spots)
which may be present. This can be removed by rubbing these parts
lightly with sand paper.
5. Holding tension in the ratchet pawl, reinstall the first brake lining plate,
ratchet wheel, and second brake lining plate onto the drive shaft.
Assemble the brake cover onto the winch with the three screws. Apply
a light coating of wheel bearing grease to the drive shaft threads and
thread the crank wheel onto the shaft by turning it clockwise. Install
the washer and bolt onto the end of the shaft. Make sure the winch is
making a clicking sound when turning the crank wheel clockwise.
6. Check the mounting of the winch to be sure that it is secure and check
the cable for any abnormal stiffness, kinking or broken strands. Replace
the winch cable at the first sign of damage. NOTE: Winch cable will last
longer and remain more flexible with occasional application of light oil.
The winch finish can be protected and will provide longer service if it is
washed with water and then wiped with light oil or wax.
If you have any questions whatsoever concerning the above procedure,
please contact the manufacturer.
OPERATING INSTRUCTIONS – Wind cable onto winch reel by turning
crank wheel in clockwise direction. This should produce a loud, sharp,
clicking noise. The load will remain in position when the wheel is released.
Wind cable off the winch reel by turning the wheel counterclockwise (no
noise will be produced). The load will remain in position when the wheel is
released, but for extra security it is recommended that the wheel be turned
clockwise until at least two clicks are heard. This will add extra tightness
to the brake mechanism. Always satisfy yourself that the winch is holding
the load before releasing the crank wheel.
CAUTION! Once the load has been lowered to the desired position,
continuing to wind cable off the drum may result in the cable becoming
tangled or may allow the cable to wind on the drum in the wrong direction.
Lifting a load by turning the crank wheel in the counterclockwise direction
could result in dropping the load. The brake only works when the load is
raised by turning the crank wheel in the clockwise direction.
NOT FOR MOVEMENT OF HUMAN BEINGS
MOTOR DRIVES – Operating the winch with a motor drive may result
in accelerated wear and reduced winch life. Dutton-Lainson Company is
not responsible for issues that are the result of operating the winch with a
motor drive.
WARNING! A motor drive may overpower the winch and/or cable and
could result in damage or personal injury.
WINCH MOUNTING AND CABLE
ATTACHMENT – Mount the winch us-
ing two 3/8” Grade 8 bolts, washers,
lock washers, and nuts. Winch may be
mounted on either side depending on
the application. To attach cable, turn
wheel clockwise until cap screws and
slot are accessible through bottom of
winch. Using 5/32” hex key, loosen cap
screws and insert end of cable through
slot between the cable clamp and inside
of reel hub. Tighten cap screws to se-
cure cable. Keep two wraps of cable on
drum before applying load.
