WARNINGS

CLUTCH MUST BE TOTALLY ENGAGED BEFORE STARTING THE WINCHING OPERATION. DO NOT DISENGAGE CLUTCH UNDER LOAD. DO NOT LEAVE CLUTCH ENGAGED WHEN WINCH IS NOT IN USE. STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS. STAND CLEAR OF CABLE WHILE PULLING. DO NOT TRY TO GUIDE CABLE. DO NOT EXCEED MAXIMUM LINE PULL RATINGS SHOWN IN TABLE. DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT PERSONNEL. A MINIMUM OF 5 WRAPS OF CABLE AROUND THE DRUM BARREL IS NECESSARY TO HOLD THE LOAD. CABLE CLAMP

IS NOT DESIGNED TO HOLD LOAD.

TECHNIQUES OF OPERATION

The best way to get acquainted with how your winch operates is to make test runs before you actually use it. Plan your test in advance. Remember, you hear your winch, as well as see it operate. Get to recognize the sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting. Gain confidence in operating your winch and its use will become second nature with you.

The uneven spooling of cable, while pulling a load, is not a problem, unless there is a cable pileup on one end of drum. If this happens, reverse the winch to relieve the load and move your anchor point further to the center of the vehicle. After the job is done you can unspool and rewind for a neat lay of the cable

When pulling a load where there is even a remote chance of cable failure, place a blanket, jacket or tarpaulin over the cable about six feet behind the hook. This will slow the snap back of a broken cable and could prevent serious injury.

NOTE: The Ramsey level winder for both drum lengths is an available accessory for tightly respooling unloaded cable onto the drum. The RAM-LOK® semi-automatic clutch allows rapid unspooling of the cable, from cable drum, for hooking onto a load. The clutch is operat-

ed by the "T-handle", located on the end of the winch, as follows:

1. TO DISENGAGE CLUTCH, run the winch in the reverse (reel out) direction until the load is off the cable. Pull outward on the clutch handle, rotate it counter-clockwise 90º and release. The clutch is now locked out and the cable may be pulled off by hand.

2. TO ENGAGE CLUTCH, pull outward on the handle, rotate it clockwise 90º and release. Run the winch in reverse until the clutch handle snaps fully in or until the cable drum starts turning. At this point make sure the clutch handle is all the way in. The plastic plug in top of clutch housing may be removed, for inspection of clutch to assure total engagement. After the clutch is fully engaged, the winch is ready for winching in the cable.

WINCH MAINTENANCE

Adhering to the following maintenance schedule will keep your winch in top condition and performing as it should with a minimum of repair. A. WEEKLY

1. Check the oil level and maintain it to the oil level plug. If oil is leaking out, determine location and repair.

2. Check the pressure relief plug in top of the gear housing. Be sure that it is in good operating condition so that hot oil gasses may escape.

3. Lubricate cable with light oil.

B. MONTHLY

1. Lubricate the various grease fittings located in the cable drum, end bearing, clutch housing or clutch operating linkage. Any good grade of moly-disulfide containing grease is acceptable.

2. Check the action of the sliding clutch, making sure it is fully engaging and disengaging with the cable drum. Remove the plastic plug in top of the housing and observe if the clutch is fully engaging. If clutch is not fully engaging, inspect clutch shifter assembly parts, check for damage or excessive wear and replace as necessary. Observe the jaws on both the clutch and cable drum, checking for rounding of the driving faces. If rounding has occurred they should be replaced immediately.

3. Check the winch mounting bolts. If any are missing, replace them and securely tighten any that are loose. Make sure to use only grade 5 bolts or better.

4. Check the torque setting of the oil cooled worm brake. Make any adjustments required, following the procedure described in ADJUSTING THE OIL COOLED WORM BRAKE in the Owner's Manual.

5. Check alignment of chain and sprockets and adjust as required to minimize wear.

6. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.

C. ANNUALLY

1. Drain the oil from the winch annually or more often if winch is used frequently.

2. Fill the winch to the oil level plug with clean kerosene. Run the winch a few minutes with no load in the reel in direction. Drain the kerosene from the winch.

3. Refill the winch to the oil level plug with all purpose E.P. 140 gear oil.

4. Inspect frame and surrounding structure for cracks or deformation.

5. Gear wear can be estimated by rocking the drum back and forth and if necessary drain oil and remove cover for closer inspection.

CABLE INSTALLATION

1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of cable, opposite hook, with plastic or similar tape to prevent fraying.

2. Insert the end of cable, opposite hook end, into the 7/16" (11 mm) diameter hole in drum barrel. Secure cable to drum barrel, using setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.

3. Carefully run winch in the "reel-in" direction. Keeping tension on end of cable, spool all the cable onto the cable drum, taking care to form neatly wrapped layers.

WINCH MOUNTING

It is most important that this winch be mounted securely so that the three major sections (the clutch housing end, the cable drum and the gear housing end) are properly aligned.

All standard model DC-200 Series Winches are furnished with recommended mounting angles. Angle size is 1/4 x 2-1/2 x 2-1/2 x 36" (6 x 63 x 63 x 914 mm) Lg. high strength (50,000 PSI [344,500 KPa] yield) steel angle.

ADJUSTING THE OIL COOLED WORM BRAKE

The oil-cooled, fully adjustable, automatic safety brake operates in the worm housing lubricant, all parts being submerged in oil. When the brake wears to the point that the load begins to drift, the brake can be adjusted as follows:

1. Loosen the lock nut on the adjusting screw.

2. Tighten the brake by turning the adjusting screw clockwise. CAUTION: Only 1/4 turn is usually required to adjust the brake.

Over-tightening can cause overheating and damage to the brake parts. Tighten the lock nut after adjustment is completed. If the brake does not respond to adjustment then a new leaf spring and brake disc is needed. A torque wrench can be equipped with a special adapter to fit the input shaft (worm) of the winch. The adapter can be made by

welding a nut to the end of a piece of tubing as shown in the following figure. After welding the cap and nut to the tubing, slot the tubing as shown. This

will allow the special adapter to slide over the keyway and will then act as a large socket. A torque wrench can then be used to apply the proper torque. Turn the torque wrench so that the drum turns in the spool out direction or lowering direction. The torque rating for the brake should be 13-18 ft-lbs. (17-24 Nm). If the torque wrench does not show the proper value as it turns, then the worm brake adjusting bolt should be turned clockwise 1/4 turn. Each time the adjusting bolt is turned, check the torque reading. Continue this procedure until the proper torque reading is achieved. Then tighten the lock nut.

SERVICING OF THE OIL COOLED SAFETY BRAKE

1. Remove the drain plug and drain the worm gear oil from the worm housing.

2. Back off the jam nut, then the adjusting screw, both two turns or more by turning them counter-clockwise.

3. Remove the cover mounting screws.

4. Remove the cover along with coil spring and leaf spring.

5. Remove the retainer plate, composition brake disc, cam plate and balls. Note slots balls are in.

6. Inspect parts as follows:

a. Composition brake discs are 1/8" (3 mm) thick when new. Replace if thinner than 0.080" (2 mm) or if surfaces are

glazed or burnt.

b. Inspect the flat, ground

surface of the cam plate and retainer plate for glazing, warpage, or other damage. Glazing can be removed by scraping carefully.

c. Inspect the leaf spring.

It should be bowed 1/8" (3 mm).

RE-ASSEMBLING AND CHECKING THE BRAKE

1. Press brake hub into place over worm shaft and key.

2. Assemble ball into appropriate slots of cam. (Refer to Diagram 1, Page 5). Use stiff grease to hold balls into place and

slide cam over end of worm. Be sure that balls are secure, between cam slots and hub slots. Refer to Page 7 to determine proper ball slot setting.

3. Install brake disc.

4. Install retainer plate, smooth side toward brake disc.

5. Install the gasket on the cover with a small amount of grease or sealer.

6. The coil spring goes over the adjusting screw on the inside of the cover.

7. Install the notches of the leaf spring on the pins protruding through the cover. The hollow side of the leaf spring goes

toward the brake.

8. Install brake housing cover, making sure the protruding pins go through the leaf spring and into the holes in the retainer

plate.

9. Bolt cover into place with the mounting screws. Install drain plug and add 1 pint all purpose E.P. 140 oil.

10. Turn winch in the hoisting direction at least one turn of the input shaft.

11. Turn the adjusting screw in until it is finger tight.

TEST FOR PROPER BRAKE ASSEMBLY

After the brake has been adjusted to the proper torque setting disengage clutch. Start vehicle engine and run winch in the reel in (hoisting direction). Allow winch to run in this direction for one minute.

Place your hand on the safety brake housing. If housing is not hot to the touch then run winch in the reverse direction (cable out) for one minute. Brake housing should begin to heat.

When these conditions exist, proper installation has been made. If heating becomes noticeable when running the winch in forward rotation (hoisting direction), the brake should be again disassembled. When disassembled, place the brake balls in the alternate set of slots in the cam plate, then carefully follow the instructions for re-assembling and checking the brake.

INSTRUCTIONS FOR CHECKING ASSEMBLY ARRANGEMENT AND SETTING OF WORM BRAKE

When the worm brake is assembled, the brake must be set with the balls in the #1 or the #2 set of cam slots. (View A-A, Page

7). It is indicated on the name plate whether the balls were installed in the #1 or the #2 slots at the factory. Three factors determine which slots the balls should be in:

1. Direction cable winds on the drum. It normally WINDS OVER THE TOP of the drum barrel.

2. The cut of the gear set, right or left gear. The last letter in the model number of the winch, either R or L, designates right or

left gear set. Example: R-20AR, R-30L, 700R, 800L.

3. The side of the winch that the input shaft is on. The INPUT SHAFT IN NORMALLY TOWARD THE CAB. Whether the winch

has the gear box on the right or on the left side of the winch does not affect the brake setting.

EXAMPLE: When cable winds over the top of the drum, winch has a right cut gear and input shaft is toward the cab (diagram

2), then the balls need to be in the #2 cam slots. If any one of these three factors differs from those stated above, the balls need to be in the #1 slots in the cam. A second

change in these factors requires the original arrangement, and if all three factors are different, the balls need to be in the #1 slots. (See Page 5 and 6 for disassembly and assembly instructions).

AVERTISSEMENTS

L’EMBRAYAGE DOIT ÊTRE ENTIÈREMENT ENCLENCHÉ AVANT DE COMMENCER TOUT TREUILLAGE. NE RELÂCHEZ JAMAIS L’EMBRAYAGE EN PRÉSENCE D’UNE CHARGE. NE LAISSEZ PAS L’EMBRAYAGE ENCLENCHÉ LORSQUE LE TREUIL N’EST PAS UTILISÉ. NE VOUS PLACEZ JAMAIS SOUS UNE CHARGE SOULEVÉE NI À PROXIMITÉ. RESTEZ À L’ÉCART DU CÂBLE LORS DU TREUILLAGE. N’ESSAYEZ PAS DE GUIDER LE CÂBLE. NE DÉPASSEZ PAS LES CARACTÉRISTIQUES DE TRACTION NOMINALES MAXIMALES INDIQUÉES DANS LE TABLEAU. N’UTILISEZ PAS LE TREUIL POUR SOULEVER, MAINTENIR OU TRANSPORTER DES PERSONNES. IL CONVIENT DE CONSERVER AU MINIMUM CINQ TOURS DE CÂBLE AUTOUR DU TAMBOUR POUR MAINTENIR LA

CHARGE. L’ATTACHE DU CÂBLE N’EST PAS CONÇUE POUR ASSURER LE MAINTIEN D’UNE CHARGE.

TECHNIQUES D’UTILISATION

Pour vous familiariser avec votre treuil, il est vivement conseillé de l’essayer avant de vraiment l’utiliser. Préparez votre essai à l’avance. N’oubliez pas que vous entendez votre treuil autant que vous le voyez fonctionner. Apprenez à reconnaître le son d'une traction légère et régulière, celui d'une lourde charge ou encore celui provoqué par des à-coups ou une déviation de la charge. Prenez l’habitude de faire fonctionner votre treuil et tout deviendra automatique.

L’enroulement irrégulier du câble lors de la traction d’une charge ne présente pas de problème sauf en cas d’accumulation du câble sur un côté du tambour. Dans ce cas, inversez le fonctionnement du treuil afin de soulager la charge et déplacez votre point d’attache vers le centre du véhicule. Une fois le travail terminé, vous pouvez dérouler le câble et l’enrouler à nouveau d’une manière régulière.

S’il existe le moindre risque de rupture du câble lors de la traction d’une charge, placez une couverture, une veste ou une bâche sur le câble à environ 1,8 m du crochet. Ceci devrait ralentir le retour du câble en cas de rupture et réduire les risques de blessures graves.

REMARQUE : Ramsey propose comme accessoire un enrouleur uniforme pour les deux longueurs de tambour. Ce dispositif permet d’enrouler serré un câble sur le tambour en l’absence de traction.

L’embrayage semi-automatique RAM-LOK® permet un déroulement rapide du câble à partir du tambour afin de le fixer à une charge. L’embrayage s'actionne comme indiqué ci-dessous au moyen de la poignée en forme de T qui se trouve à l'extrémité du treuil.

1. POUR RELÂCHER L’EMBRAYAGE, faites fonctionner le treuil en marche arrière (déroulement) jusqu’à ce que la charge ne porte plus sur le câble. Tirez la poignée d'embrayage vers l’extérieur, faites-la tourner de 90º dans le sens inverse des aiguilles d’une montre, puis relâchez-la. L’embrayage est alors supprimé et le câble peut être tiré à la main.

2. POUR ENCLENCHER L’EMBRAYAGE, tirez la poignée vers l’extérieur, faites-la tourner de 90º dans le sens des aiguilles d’une montre et relâchez-la. Faites tourner le treuil en marche arrière jusqu’à ce que sa poignée se réenclenche complètement ou jusqu’à ce que le tambour commence à tourner. À ce point, assurez-vous que la poignée est complètement rentrée. Il est possible de retirer le bouchon en plastique du haut du carter afin de vérifier si l'embrayage est bien enclenché. Une fois l’embrayage entièrement réenclenché, le treuil est prêt à enrouler le câble.

ENTRETIEN DU TREUIL

L’observation du calendrier de maintenance suivant vous permettra de maintenir votre treuil en bon état et garantira un fonctionnement avec un minimum de réparations.

A. HEBDOMADAIRE

1. Vérifiez le niveau d’huile et maintenez-le au niveau du bouchon. En cas de fuite d’huile, déterminez l’emplacement de la fuite et réparez.

2. Vérifiez le bouchon d’échappement en haut de la boîte d’engrenages. Assurez-vous qu’il fonctionne bien afin que les gaz issus de l’huile chaude puissent être évacués.

3. Lubrifiez le câble avec de l’huile légère.

B. MENSUEL

1. Lubrifiez les divers graisseurs situés dans le tambour du câble, le roulement d’extrémité, le carter d’embrayage ou la tringlerie d'embrayage. Vous pouvez utiliser toute graisse de bonne qualité contenant du bisulfure de molybdène.

2. Vérifiez l’action du crabot baladeur et assurez-vous qu’il s’enclenche sur le tambour du câble et s'en dégage complètement. Retirez le bouchon en plastique du haut du carter et vérifiez si l’embrayage s’enclenche bien. S'il ne s'enclenche pas à fond, examinez les pièces de l'embrayeur afin de déceler toute trace de détérioration ou d’usure excessive, et procédez aux remplacements éventuellement nécessaires. Observez les mâchoires de l’embrayage et du tambour afin de déceler tout arrondissement des surfaces. Si elles se sont arrondies, changez immédiatement les pièces.

3. Vérifiez les boulons de fixation du treuil. Remplacez tout boulon manquant et serrez fermement les autres. Veillez à utiliser uniquement des boulons de grade 5 ou supérieure.

4. Vérifiez le couple de serrage du frein à vis sans fin refroidi à l’huile. Procédez à tout réglage nécessaire, conformément à la procédure décrite dans la section RÉGLAGE DU FREIN À VIS SANS FIN REFROIDI PAR HUILE du manuel de l’utilisateur.

5. Vérifiez l’alignement de la chaîne et des pignons, et procédez aux réglages nécessaires pour réduire l’usure.

6. Examinez le câble. Tout câble dénudé ou effiloché doit être remplacé immédiatement.

C. ANNUEL

1. Le treuil doit être vidangé une fois par an ou plus souvent en cas d’usage fréquent.

2. Remplissez le treuil de kérosène propre jusqu’au niveau du bouchon de niveau d’huile. Faites fonctionner le treuil quelques minutes sans charge, dans le sens de l’enroulement. Éliminez le kérosène du treuil.

3. Remplissez le treuil d’huile pour engrenages E.P. 140 polyvalente jusqu’au bouchon de niveau d’huile.

4. Examinez le châssis et la structure afin de déceler toutes déformations ou fissures éventuelles.

5. Pour évaluer l’usure des engrenages, secouez le tambour et, si nécessaire, vidangez l'huile et retirez le couvercle pour un examen plus approfondi.

INSTALLATION DU CÂBLE

1. Déroulez le câble sur le sol pour éviter qu'il ne se torde. Recouvrez bien l’extrémité du câble opposée au crochet d’un ruban adhésif plastique ou de type équivalent pour éviter qu’elle ne s’effiloche.

2. Insérez l’extrémité du câble opposée au crochet dans le trou de 1,2 cm de diamètre du tambour. Fixez le câble sur le tambour au moyen de la vis de pression fournie avec le treuil. SERREZ FERMEMENT LA VIS.

3. Faites tourner avec précaution le treuil dans le sens de l’enroulement. Conservez une tension sur l’extrémité du câble et enroulez tout le câble sur le tambour en veillant à former des couches régulières.
