WARNINGS:

THE USER SHALL ENSURE THAT THE OPERATING PERSONNEL ARE GIVEN THE NECESSARY TRAINING. THE OPERATOR SHALL ALWAYS WORK IN COMPLIANCE WITH THE OPERATING INSTRUCTIONS. CLUTCH MUST BE FULLY ENGAGED BEFORE STARTING THE WINCH.

DO NOT DISENGAGE CLUTCH UNDER LOAD.

STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS.

STAND CLEAR OF ROPE WHILE PULLING. DO NOT TRY TO GUIDE ROPE.

DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT PERSONNEL.

A MINIMUM OF 2 WRAPS OF ROPE AROUND THE DRUM BARREL IS NECESSARY TO HOLD THE LOAD. AVOID CONDITIONS WHERE LOAD SHIFTS OR JERKS OCCUR. EXCESSIVE “INCHING” SHALL BE AVOIDED.

User’s Responsibility for CE Compliance

1.Mount winch per Installation Instructions.

2.Install the emergency stop switch per Installation Instructions included with the Emergency Stop Switch Kit.

3.Install 10 mm (.393 in) grade 1960 wire rope. Maximum Rope length of 28 M (95 ft) for three layers maximum.

4.Attach rope to the drum per Rope Installation Instructions.

5.Use a hook which includes a safety latch and has a minimum breaking strength of 87 kN.

WINCH MOUNTING

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

All standard model DC 34,9 winches are furnished with recommended mounting angles. Angle size is 9 x 63 x 63 x 914 mm (3/8 x 2-1/2 x 2-1/2 x 36”) Lg. high strength 344,500 KPa (50,000 PSI) yield steel angle.

ROPE INSTALLATION

1. Unwind rope by rolling it out along the ground to prevent kinking. Securely wrap end of rope, opposite hook, with plastic o r similar tape to pre vent fraying.

2.Slide the wire rope through narrow end of the pocket against the drum flange. Wrap the wire rope around on the anchor “puck” (item #38) and pull the wire rope and anchor back into the wide end of the pocket. Use a soft hammer to drive the back side of the wire rope, firmly seating the wire rope and anchor into the pocket.

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

TECHNIQUES OF OPERATION

The uneven spooling of rope, while pulling a load, is not a problem, unless there is a rope 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 rope

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

Check oil level of winch every six months. Replace oil annually or more often if winch is used frequently. Use 0.35 L (0.75 pint) of all purpose E.P. 140 oil in the worm gear housing and 0.23 L (0.5 pint ) SAE 20 for spur gear box. If the oil is contaminated with metallic particles, inspect winch for cause of abnormal wear.

Periodically check all electrical connections and mounting bolts. Tighten hardware if necessary.

The minimum ampere-hour rating of vehicle battery should be 70, and used with at least a 40 ampere alternator. An auxiliary battery is recommended to supply additional battery power.

Inspect the rope frequently. If the rope becomes frayed with broken strands, replace immediately. The RAM-LOK® semi-automatic clutch allows rapid unspooling of the rope, from rope drum, for hooking onto a load. The clutch is operated 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 rope. Pull outward on the clutch handle, rotate it counter-clockwise 90º and release. The clutch is now locked out and the rope 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 rope 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 rope.

5

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 rope with light oil.
B.	MONTHLY

1.Lubricate the various grease fittings located in the rope 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 rope 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 rope 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.Inspect the rope. If the rope 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.

ELECTRICAL CONNECTIONS

For normal self-recovery work, your existing electrical system is adequate. Your battery must be kept in good condition. A fully charged battery and proper connections are essential. Run the vehicle engine during winching operation to keep battery charged. Connect red cable from stud on plastic solenoid cover on winch to emergency stop solenoid. Important:

Hold inner nut with end wrench while tightening outer nut. Install emergency stop switch and solenoid per kit # 282067 (12V) or 282068 (24V) as applicable.

Connect black cable from motor ground stud to negative battery termi nal. A good electrical ground is required for proper performance. The remote control switch is waterproof and has push button stations on either side. It is designed this way to prevent quick winch reversals, which lead to solenoid failure. Make sure the winch motor has stopped fully before reversing. When first setting up your winch, follow the directions for inserting the proper “IN” or “OUT” label in the thumb button. The switch is also color coded to aid you in determining the direction your winch will run.

ADJUSTMENT OF RATED LOAD LIMITER

1.Make some test pulls with winch (using a load cell or spring scale) to determine if switch is at desired rated load set ting.

Applicable setting is 100% to 125% of rated load.

2.If load is not within above range, remove tamper-proof compound in threaded hole (on top of set screws #4). Remove top set screw.

3.Loosen bottom set screw approximately 2 turns counter clockwise.

4.To reduce line pull, thread switch #1 “IN” by turning clockwise. To increase line pull, the switch “OUT”.

5.After desired setting is reached, tighten bottom set screw securely.

6.Re-install top set screw and tighten securely. Fill threaded hole with a potting-type compound which must be removed before any future adjustment is made.

When winch reaches the end of its serviceable life, dispose of per local environmental regulations.

TEST PROCEDURE FOR SOLENOIDS

Steps to follow when testing current flow through DC solenoids.

It should be noted that when testing a 12 volt or 24 volt solenoid, the DC motor and battery must be of the same voltage.

To test the solenoids: (See Figure 1).

1.Securely clamp a motor to a bench or work surface.

2.Attach a #6 gauge jumper wire from “A” terminal on the motor to one of the field terminals on the motor, (F-2).

3.Attach the other motor field terminal (F-1) to one of the side terminals of the solenoid.

4.Ground the solenoid to the motor with a wire as shown.

5.Attach positive (+) battery wire to the opposite side terminal of solenoid. Ground the negative (-) battery wire to the motor housing.

6.Touch “hot” wire, from the positive battery terminal, to small terminal of the solenoid.

7.The motor should now be running if the solenoid is good. If not, make sure the motor will run directly from the battery. (See motor test procedure, Page 17).

8.To test the upper contacts use the same hookup except use the top terminals. (See Figure 2). When hooked up as shown in Figure 2, motor should start running.

When the “hot” wire is touched to the small terminal the motor will stop operating.

The top terminals are normally closed; i.e. connected, and the side terminals open, or not connected. When the solenoid operates, the top terminals are disconnected and the side terminals are connected.

Take care not to bring “hot” wires into contact with ground in order to prevent electrical arcing.

17

TEST PROCEDURE FOR MOTOR

The Ramsey Winch motor is a (4 pole-4 coil) series wound 12 volt or 24 volt DC motor.

The 4 pole-4 coil feature provides high torque at low speeds.

To test the motor to determine if it is functioning properly, first securely fasten the motor to a bench or work surface so it will not jump or move around during test procedure (the starting torque of motor is high).

1.Connect a jumper wire (at least a number 6 wire) from F-1 to “A” motor terminals (See Figure 1)

2.Attach a wire (at least a number 6 wire) from positive

(+) battery terminal to F-2 motor terminal. Ground negative (-) battery terminal to motor housing (See Figure 1). Motor should now run.

To reverse the direction of rotation:

1.Attach jumper wire from F-2 to “A” motor terminals (See Figure 2).

2.Attach wire from positive (+) battery terminal to F-1 motor terminal. Ground negative (-) battery terminal to motor housing (See Figure 2).

NOTE: Always attach battery wire solidly to motor terminals. Make and break the connection of the negative (-) battery terminal at the motor housing. This avoids burning the motor terminals.

CAUTION: DO NOT RUN THE MOTOR FOR A LONG PERIOD OF TIME IN FASHION MENTIONED ABOVE, BECAUSE THE MOTOR COULD BECOME DAMAGED.

The motor running idle on the bench will draw 55 amperes and must run free and easy. If the ampere draw is more than 60 amperes and the motor runs rough or has a strange sound, it should be replaced.

With the motor attached in place on a winch (less cable on drum) the ampere draw should be approximately 65 to 70 amperes.

If after following the procedure outlined, the test on the winch significantly exceeds 70 amperes, refer to your Owner’s Manual for trouble shooting suggestions on the mechanical portion of the winch.

See Figure 3 for the solenoids connection to the motor and the battery.

21

FIXATION DU TREUIL

Ce treuil doit absolument être monté correctement afin que les trois principales parties soient alignées (l’extrémité du carter d’embrayage, le tambour du câble et l’extrémité de la boîte d’engrenages).

Tous les modèles standard de treuil DC 34,9 sont fournis avec des cornières de montage recommandées. Ces cornières mesurent 9 x 63 x 63 x 914 mm (3/8 x 2-1/2 x 2-1/2 x 36 po) et sont fabriquées en acier haute résistance, soit 344 500 KPa (50 000 PSI).

POSE 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 avec un r uban adhésif plastique ou de type équivalent pour éviter qu’il ne s’effiloche.

2.Insérez le câble dans la partie étroite du logement, contre la collerette du tambour. Enroulez le câble autour du galet d’a ncrage (pièce no

38)et rentrez les deux dans l’extrémité large du logement. Utilisez un marteau-caoutchouc pour acheminer l’arrière du câble, e n le plaçant fermement avec le galet d’ancrage dans le logement.

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

TECHNIQUES D’UTILISATION

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 (6 pi) du crochet. Ceci devrait ralentir le retour du câble en cas de rupture et réduire les risques de blessures graves.

Contrôlez le niveau d’huile du treuil tous les six mois. Remplacez l’huile tous les ans ou plus souvent en cas d’utilisation fréquente. Utilisez 0,35 l (0,75 pinte) d’huile E.P. 140 polyvalente dans la boîte de la vis sans fin et 0,23 l (0,5 pinte) de SAE 20 dans la boîte d’engrenages Si l’huile est souillée par des particules métalliques, examinez le treuil afin de déceler tout signe d’usure anormale.

Vérifiez régulièrement tous les branchements électriques et tous les boulons de fixation. Serrez les pièces si besoin est.

La caractéristique minimale d’ampère-heure de la batterie du véhicule doit être de 70 et celle-ci doit être utilisée avec un alternateur d’au moins 40 ampères. Il est conseillé de disposer d’une batterie de secours pour fournir une alimentation supplémentaire.

Inspectez fréquemment le câble. Tout câble effiloché ou comportant des brins brisés doit être remplacé immédiatement. 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 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 afin de vérifier si l’embrayage est bien enclenché. Une fois l’embrayage entièrement réenclenché, le treuil est prêt à enrouler le câble.
