Important Safety Information
DO the following:
Read carefully and comply with the guidelines set forth in the Owner’s Manual.
Keep hands away from the drum, gears, wire cable, and other moving parts of the equipment.
Keep all unnecessary personnel away from the winch while in operation.
Keep out of the path of the winching operation should the wire cable break and snap back and cause injury.
DO NOT do the following:
Do not lift people, or objects over people. Do not walk or work under or in the line of force of any winching operation.
Do not exceed the load rating of the winch or any other component in the system. To do so could result in failure of the equipment.
Do not use more than one winch to move a boat that exceeds the load rating of a single winch. A shift in load weight could overload the equipment.
Do not use damaged or malfunctioning equipment. To do so could result in failure of the equipment.
Do not modify the equipment in any way. To do so could cause equipment failure.
Do not winch a boat onto a trailer with the wire cable / webbing / fibre rope fully extended. Keep at least three full turns of cable / fibre rope (or one
turn of webbing) on the drum.
Do not wrap the wire cable / around the load. This may damage the wire cable / fibre rope and could damage the boat. Use a sling, shackles or other
approved devices.
Do not operate the winch with covers removed or improperly installed.
Do not divert your attention from the operation. Stay alert to the possibility of accidents, and try to prevent them from happening.
Do not jerk or swing the boat. Avoid shock loads by starting and stopping the winching operation smoothly. Shock loads overload the equipment and
may cause damage to both the winch and boat.
Do not leave a suspended load unattended unless specific precautions have been undertaken and keep people away from the winch and out from under
the load.

General theory of operation
Important !
Limit non-uniform winding by keeping tension on the wire cable.
It is the operators’ responsibility to detect and account for different factors affecting
the condition and performance of the equipment.
The pull required to move the boat must not exceed the load rating of the winch. Consider the total force required to move the boat, not the weight of
the boat.
The winch can develop forces that will exceed the load rating. It is the responsibility of the winch operator to limit the size of the load. Inspect the
winch regularly for damage according to the instructions contained in the Owner’s Manual.
Performance ratings of the winch are affected by the amount of wire cable or webbing wound onto the drum, the way in which it is wound, and the
way the winch is used.
Drum capacity depends on how tightly and evenly the wire cable is wound onto the drum. Actual drum capacities are usually 25- 0% less than the
values shown in performance tables, due to loose winding and overlapping.
Load rating represents the maximum pull that can be placed on a new winch. Load ratings are assigned values for specific amounts of load travel or
wire cable accumulation. The load rating decreases as layers of wire cable accumulate on the drum.
Duty ratings refer to the type of use the winch is subject to. Consider the following when determining duty rating.
Environment: harsh environments include hot, cold, dirty, wet or corrosive surroundings. Protect the winch against harsh environments
when possible.
Maintenance: poor maintenance, meaning poor cleaning, lubrication or inspection, leads to poor operation and possible damage of the
winch. Minimise poor maintenance by carefully following the instructions contained in the Owner’s Manual.
Loading: severe loading includes shock loading and moving boats that exceed the load rating of the winch. Avoid shock loads, and do not
exceed the load rating of the winch.
Frequency of operation: frequent or lengthy operations increase wear and shorten the life span of gears, bushes, and other
components. Increase maintenance of the winch if used in frequent operations.

Installing the Winch
Important !
Inspect the winch immediately following installation. This will give provide a record of
the condition of the winch from which to compare future inspections.
Warning Do not install the winch near corrosive chemicals, flammable materials or other elements that may damage the winch
or injure the operator. Adequately protect the winch and operator from such elements.
Position the winch so the operator can stand clear of the boat, and out of the path of possible broken wire that could
snap back and cause injury.
Attach the winch to a rigid and level / flat foundation base that will support the winch and the boat under all load /
unload conditions, including shock loading.
Locate the winch in an area clear of traffic and obstacles that could interfere with its operation. Make sure the winch is accessible for maintenance and
operation.
The winch should be positioned onto a solid / flat foundation base (able to support the winch and the load / unload operations under all conditions) in the
front of and central to the trailer. This ensures a balanced winching operation whilst loading / unloading the boat.
Fasten the winch securely to the boat trailer, utilising all four mounting holes to ensure maximum capacity. 4ea. M10 galvanised or G 16 stainless steel
bolts, flat and spring washers and nuts should be used to secure the winch to the boat trailer.
Installing wire cable / fibre rope / webbing onto Jarrett winches
Important !
•Use wire cable and other rigging equipment rated for the capacity of the winch.
•Do not drag the wire cable through dirt or debris that could cause damage, or poor operation.
•Always wear protective clothing when handling wire cable.
•Install the wire cable securely to the winch drum. A poorly secured wire cable could come loose
from its anchor and could release the load.
•Ensure the wire cable is wound correctly or the winch may not work properly and could release the load.
•Always ensure that a minimum of three full turns remain on the winch drum at all times.
Where wire cable / fibre rope / webbing is not supplied or is to be replaced, purchase the proper wire cable / fibre rope / webbing
for your application. Keep the following in mind when selecting. Contact a reputable supplier for assistance.
Breaking strength of new wire cable / fibre rope / webbing should be at least 2 times greater than the rating of the winch.
Wire cable lay must agree with the winding direction of the drum to insure proper winding.
Secure the wire cable / fibre rope / webbing to the winch drum as per the securing instructions below.
Test the wire cable / fibre rope / webbing installation by operating the winch. The pawl (ratchet) operates in one direction only. Make sure the pawl
(ratchet) engages to resist the force of the load.
Wind three full turns of wire cable onto the drum by operating the winch whilst holding the wire cable taut. These turns serve as an anchor wraps and
must remain on the drum at all times.
Dependant on Boat Trailer Winch model, two securing methods for cable are applicable:
Instruction for securing a cable to a winch using a plate clamp fitting
1. Tape the cable end using 50mm – 70mm of plastic tape. This is to stop the cable end from fraying and causing injury in use.
2. Fold the end of the cable (approximately 0mm) back on itself and permanently kink the end.
. Feed the taped end of the cable through the round hole of the drum flange (disc)
from inside the drum.
4. Place one of the cup head bolts into Hole 1 of the clamp fitting, with the head on the inside of
the drum assembly, and pull the cable tight against the bolt. Attach the nut and tighten.
5. Align the second hole in the plate with Hole 2, and secure with the second bolt and nut.

Instruction for securing a cable to a winch using a single bolt fitting
1. Place the cup headed bolt into the square hole with the head on the inside of the drum assembly.
2. Screw on the combination nut and washer only 2- threads.
. Tape the cable end using 50mm – 70mm of plastic tape. This is to stop the cable end
from fraying and causing injury in use.
4. Feed the taped end of the cable through the round hole of the drum flange (disc) from inside the drum
and double back to loop the cable under the bolt, behind the washer and back towards the round hole.
5. While holding the cable in place under the nut with the left hand, pull the cable tight with the right hand.
6. Using the thumb of the left hand hold the cable in place inside the drum and tighten the nut to secure
the cable in place. View from outside the drum
showing cable flow
Turn the handle to wind the wire cable onto the winch drum. Uniformly wind the wire cable onto
the winch drum by holding the wire cable taut.
Instruction for securing fibre rope to winch – Note: Fibre rope to be ≤ Ø7mm
1. Take the winch drum with the gear facing the assembler and the free end of the rope and wrap three turns around the hub of the drum in an
anticlockwise direction.
2. Take the free end and pass it between the three turns and the drum hub and then pass the free end over the three turns on the drum and under
the last turn.
. Pass free end of the rope under the last bite and through the ‘cable’ hole in the flange. Pull firmly so that the turns on the drum lie reasonably flat.
The length protruding needs to be about 150mm.
4. Insert from inside the drum flange (centre hole) the M6 square neck cup head bolt and screw the M6 flanged serrated hexagon nut onto the bolt.
5. Wrap the rope around the M6 bolt inside the flanged serrated hexagon nut. Secure the fibre rope by tightening the nut using an M6 spanner.
When securing, ensure that the rope fibres do not catch on the bolt threads and that the rope stays inside the flanged section. Trim any excess
rope.
6. The turns around the drum will have become loose. Work the turns so that the rope lays flat against the hub and there is no slack.
Instruction for installing / replacing webbing
To install the webbing, perform the following steps bar # .
To replace the webbing, perform all the following 7 steps.
1. gently knock out the roll pin that secures the winch drum to the shaft - a round punch or screwdriver will suffice - providing that they are smaller in
diameter than the roll pin. Light / 'firm' taps with a small hammer should remove the roll pin.
2. gently knock out the shaft to a point where it releases the webbing - be careful not to burr over the shaft corner/edge or damage the bushing
. remove old webbing
4. ensure loop of new "Jarrett" brand webbing is flexible/loose
5. locate webbing 'loop' into slot of the winch drum and secure with shaft (which goes through the loop)
6. gently relocate shaft into bushing - a drop of general purpose oil on the bushing would not go astray
7. align pin hole on winch drum and shaft and gently tap in roll pin till it is flush
Preparing for Operation
Important !
When determining whether the boat will exceed the load rating, consider the total force required to move the boat.
Consider the operation. Do not begin until you are sure you can perform the entire operation without hazard.
Inspect all components of the system.
Inspect the winch and other equipment in accordance with Inspection instruction.
Operators should be in good health, alert and suitably clothed (i.e. no loose clothing)
The boat must be clear of objects and free to move. Ensure the boat will not tip, spin, roll away, or in any way move uncontrollably.
Know your boat and make sure you do not exceed the load rating of the winch or any other equipment in your system.
Attaching the Boat
Warning Do not wrap the wire cable / fibre rope around the boat winch connection. This damages the wire cable / fibre rope
and could damage the boat. If necessary, use a sling or other approved device.
Clear objects from the path of the boat so you can move it freely and observe it at all times during the operation.
Attach the boat using a nylon sling, shackle or other approved rigging device.
Seat the sling / shackle in the saddle of the snap hook with the hook latch completely closed. If an S-Hook is used, the sling / shackle is positioned in the
S-hook, and the winch drum operated slowly to retrieve the slack cable / webbing / fibre rope. When the cable / webbing / fibre rope is taut, check to
ensure the sling is correctly positioned in the S-hook / snap hook prior to moving the boat.
Centre the load on the hook so the boat will remain balanced and not tip or rotate to one side.

Moving the Boat
Important !
•Obey a stop signal from anyone.
•Maintain tension on the wire cable to keep it tightly and evenly wound on the drum.
•If the winch and boat are not visible during the entire operation, get help from another person.
•Appoint a supervisor if more than one person is involved in the operation. This will reduce confusion and increase safety.
•Where possible, remove the handle when the winch is not in use, to help avoid unauthorised use.
Move the boat slowly and smoothly, only a small distance at first. Make sure the boat is balanced and securely attached before continuing.
Engage the pawl (ratchet) when winding the boat towards the winch, disengage the pawl (ratchet) when releasing the boat. Do not engage the pawl
(ratchet) while the winch gears are turning. Stop the winch before engaging the Pawl. Ensure the handle is securely positioned on the shaft.
Grip the handle tightly at all times during operation. When required, disengage the Pawl by moving the load slightly to remove pressure from the
Pawl, then pull out and turn the Pawl lever 90 degrees. Do not try to stop a spinning handle, step clear until the spinning stops.
Observe the wire cable as it winds onto the drum. If it becomes loose, uneven, or overlapped, stop the operation and rewind before continuing.
Continued operation with overlapped or uneven wire cable can damage and shorten its life.
Cleaning the Winch
Important !
Increase the frequency of maintenance procedures if the winch is:
•Operated for long periods.
•Used to pull heavy loads.
•Operated in wet, dirty, hot or cold surroundings.
Clean the winch to remove dirt and help prevent rust and corrosion.
Clean the winch every three months or whenever it is dirty.
Wipe all components to remove dirt and grease.
Leave a light film of oil on all surfaces to protect them against rust and corrosion.
Wipe off excess amounts of oil to avoid accumulation of dirt.
Remove all unnecessary objects from the area surrounding the winch.
Lubricating the Winch
Important !
Make sure the lubricant has a temperature rating appropriate for the ambient temperatures of the operation.
Lubricate the winch properly to help protect it from wear and rust.
Lubricate the winch at least every three months, by applying a light grade oil to the drum shaft and bushes. Rotate the drum several times to allow oil to
penetrate, and wipe off excess oil to avoid dirt accumulation.
Inspecting the Winch and other associated equipment
Important !
Keep written records of inspection. This allows comparison with comments from previous inspections so
you can see changes in condition or performance
Warning Do not use damaged or malfunctioning equipment. Seek immediate repair.
Inspect the winch to detect signs of damage or poor operation before they become hazardous.

A commonly used ratio of boat size to winch capacity is 2 to 1. However, the ratio can be stretched to to 1 using a trailer in
excellent condition.
A guide to the rolling load (pulling) capacity of a winch (in excellent condition) pulling a boat onto a trailer equipped with fitted keel
rollers and side wobbles (in good condition) is as per the following table. For example, a 00kg winch can pull a 900kg boat onto a
trailer (equipped with fitted keel rollers and side wobbles) with a 10 degree incline (i.e. 20% incline).
The ratio should be reduced to 1 to 1 on trailers with wooden bunks and no self-alignment capabilities.
