DL STRONGARM SA7000 (01) PDF DOCUMENT

You must read all instructions carefully before attempting to install, operate, or service the DL STRONGARM SA7000. Failure to comply with instructions could result in serious or fatal injury. Retain instructions for future reference.

WARNING: NOT TO BE USED AS A HOIST FOR LIFTING, SUPPORTING, OR TRANSPORTING PEOPLE OR LOADS OVER AREAS WHERE PEOPLE COULD BE PRESENT.

• This winch is not designed for the movement of human beings. Do not use it for scaffolding, elevators, or any other application in which persons could be positioned on or under the load at any time. Do not use it as an overhead hoist.
• This electric winch should be respected as power equipment. High forces are created when using a winch, creating potential safety hazards. Never allow children or anyone who is not familiar with the operation of the winch to use it.
• Never exceed rated winch capacity. Dangerously high forces can be created if the load being moved is too large or is allowed to get in a bind. If overloaded, this winch has enough power to break the cable.
• Keep the winching area free of all unnecessary personnel. Never stand between the load and the winch.
• When the winching operation has been completed, do not depend on the winch to support the load. Always secure the load properly using tie-down straps or chains.
• Keep hands and fingers clear of the drum and cable area of the winch when operating. Do not attempt to guide the cable by hand as it rewinds on the drum.

The 12-volt D.C. winch operates from a low voltage D.C. source of power, such as a car or truck battery. DO NOT connect the winch to 120V A.C. power.

Yes. The electric motor is designed for intermittent service only. Extended use without cooling-off periods will cause overheating, resulting in motor damage.

CAUTION: CONTINUOUS RUNNING IN EXCESS OF 4 MINUTES WILL DAMAGE THE WINCH MOTOR.

Additionally, never apply a load to the winch with the cable fully extended. Keep at least three turns of cable on the reel at all times.

1. Ensure the mounting surface is of sufficient strength to support a load well in excess of the rated winch capacity.

2. Fasten the winch to the mounting surface with three 1/2″ bolts, nuts, washers, and lockwashers, following the base hole pattern.

3. Position the winch so that the cable does not rub against the front opening of the winch.

4. If using quick-mounting shoulder studs (the winch is equipped with keyhole slots for this), they should be mounted securely into the mounting surface. After positioning the winch on the studs, a 3/8″ bolt should be placed in one of the other available holes to keep the winch securely in position.

5. For double line use, install an eye-hook on the mounting surface close to the base of the winch for fastening the stationary cable hook. Ensure the eye-hook is strong enough to withstand loads in excess of the single line rating of the winch.

6. The winch must be securely attached to a structural member or frame that is capable of sustaining loads in excess of the winch capacity. When attaching the winch to a vehicle, make sure the mounting pad area is rigidly supported by the vehicle frame. Always block the wheels to prevent the vehicle from rolling when pulling a load with the winch. Do not use vehicle pulling power to increase the pulling capacity of your winch.

1. Attach the circuit breaker assembly on the end of the positive (+) wire to the positive battery terminal.

2. Attach the negative (-) wire (ground) to the negative battery terminal or a convenient ground location.

3. Make certain that all connections are clean and tight.

4. If the wiring is being permanently installed in a vehicle, secure the wires so they cannot come into contact with hot or moving parts.

With the wires at the bottom, push the switch/plug into the pocket in the winch housing. The switch should push easily to the bottom of the pocket, and excess force should not be required for installation or removal. Rotate the switch in the direction indicated on the winch decal to power the load in or out. Be sure the wires are free to rotate with the switch so that it will return to its center “Off” position when released.

All models can be powered in or out. Allowing the switch to return to the “off” position will automatically stop the winch and hold the load.

NOTE: It is normal for smoke to be produced during the initial power down use.

Be sure the battery is fully charged and in top condition to avoid power loss. If using a vehicle battery, leave the engine running on fast idle as a precaution in case the battery is not in top condition.

When the winching operation is complete, secure the load properly with tie-down straps or chains. Do not depend on the winch to support the load. Also, remove the power supply plug from the winch to avoid accidental operation.

WARNING: Even though the winch is equipped with circuit breaker overload protection, particular care should be taken not to create an overload. Pay attention to the sound of the winch and the load being pulled. Make certain that the cable tension does not rise suddenly because of a bind in the load.

The DL STRONGARM SA7000 is factory equipped with a pulley block and hook and 50′ of cable for double line operation. This increases the pulling capacity of the winch as shown in the ratings. However, care must be taken to allow adequate motor cooling. Note that with a double line, a pull of 25′ requires reeling in 50′ of cable.

This is for intermittent use only. For longer pulls, motor cooling periods must be allowed.

The emergency crank handle is provided for use in the event of a power failure. Follow these steps:

1. Remove the electrical power from the winch.

2. Remove the plastic plug from the side of the winch housing and insert the handle so that it completely engages with the drive shaft. The handle can be cranked in either direction.

WARNING: NEVER OPERATE THE WINCH ELECTRICALLY WITH THE EMERGENCY HANDLE IN POSITION.

3. Always remove the handle from the winch after use and replace the plastic plug.

The auxiliary handle is for emergency use only. Never use the auxiliary handle as an assist to the motor when the motor is running. Always remove the auxiliary handle when it is not in use.

The dead weight capacity of the DL STRONGARM SA7000 varies based on the length of cable on the reel and whether you are using a single or double line setup. The capacity decreases as more cable is let out (and less is on the reel).

• SA7000, SA7015 double line: Capacity ranges from approximately 4,400 lbs with 10 ft of cable on the reel down to 2,200 lbs with 50 ft of cable on the reel.

*Load capacity (dead weight) is a measure of actual maximum force to which the winch system may be subjected.

The following table shows the maximum rolling load weight in pounds and kilograms that the DL STRONGARM SA7000 can pull on different inclines. These capacities are shown with 15′ of cable on the reel and a 10% rolling friction factor. For a full reel of cable, adjust capacities according to the dead weight capacity graph.

The speed of the DL STRONGARM SA7000 varies with the load and the amount of cable on the reel (Full Reel vs. Empty Reel).

For long life and trouble-free operation, your winch should be periodically inspected for any required maintenance. This should be done at least once annually and more frequently in adverse conditions such as saltwater areas or areas of extreme dust and dirt.

1. Cable Inspection: Carefully inspect the winch cable for any kinks, frays, or abnormal stiffness and replace it at the first sign of this kind of damage. Periodic lubrication with a light oil will improve the life of the cable. When cable breaks under tension, it tends to whip toward the winch area. It is recommended that a blanket or rug be placed over the cable during winching operations to minimize this whipping action in case of cable breakage.

2. Gear Train Inspection: With the cover removed, inspect the entire gear train and all drive shafts for any significant wear or loose bearing fits. Grease all of the gears on the inside of the winch base and apply a drop of oil on all of the bearings in the base. Also, place a drop of oil on the roller clutch. Do not over-lubricate these areas and do not use grease in the roller clutch. The brake pads and brake disc must be kept clean and oil-free.

3. Roller Clutch Check: Check the operation of the roller clutch. Carefully rotate the brake disc and observe the motor shaft. When the disc is turned clockwise, the motor shaft should turn with it. When the disc is turned counterclockwise, the motor shaft should not turn. Also, check all nuts, bolts, retaining rings, etc., to be sure that they are tight and secure.

4. Switch Contacts Check: Check the switch contact studs in the winch housing to be sure that they are free from any corrosion or excessive electrical pitting. Make sure that the housing shunt spring is properly in place and making contact with both contact pins. If the motor will not run in either direction or runs in only one direction, further diagnosis and corrective action may be needed.

5. Pulley Block Check: If a pulley block and hook is used, check the assembly to be sure that the pulley rotates freely on the bronze pulley spacer. Occasional greasing of these two items is recommended.

1. Disconnect the power from the winch.

2. Remove the four cover mounting bolts.

3. Lift the housing off of the winch by gently stretching it open near the lower front corner.

4. Rotate the winch reel so that you have access to the rope clamp.

5. Remove the old cable and replace it with a new cable of the same size.

6. Ensure that the cable passes under both sides of the rope clamp and that the clamp is tightened securely.

NOTE: On the DL STRONGARM SA7000, the cable is wound OVER THE TOP of the drum.
