load the unit, then check to be sure that the attachments to the hooks and load are firmly seated. Continue movement only after you are assured the load is free of all obstructions. The hoist has been designed for hand powered operation only. Do not use an extension on the lever. Lever pulls of

TO LOOSEN OR LOWER LOAD
WARNING
POWER OPERATION MAY CAUSE STRUCTURAL DAMAGE OR PREMATURE WEAR THAT IN TURN MAY CAUSE A PART TO BREAK AND ALLOW THE LOAD TO FALL.
OPERATE THETORS2AVOIDLEVERINJURY:HOIST USING HAND POWER ONLY!
Move lever trigger to “DN” position. Again, operate lever in an up and down motion to increase the distance between hooks and thus loosen or lower the load.
Note that the cam is NOT changed when changing from “up” to “down” or from “down” to “up” operation.
As a result, the lever will move but, there will be no corresponding movement of the lower hook or load, when the unit is operated in the “up” direction. Should this occur, immediately move the trigger to the “DN” position and operate the lever until the overload is set down and removed from the unit. Reducing the load to rated capacity or less will automatically return the hoist to normal operation.
CAUTION: THE LOAD LIMITER IS SUBJECT TO OVERHEATING AND WEAR WHEN EXCESSIVELY OPERATED. FOR THIS REASON, WHEN AN OVERLOAD IS DETECTED, THE EXCESS LOAD MUST BE REMOVED AS QUICKLY AS POSSIBLE WITHOUT CONTINUED OPERATION OF THE LEVER.
Under certain conditions, such as applying an overload and removing it by external means, the brake may become “locked”. This results in not being able to operate the unit in the “down” direction. Should this occur, move the trigger to the “DN” position and give the lever a sharp pull and then additional strokes to lower the load and remove tension from the unit.
WARNING - TO AVOID INJURY: Use as directed above. Failure to do so may cause injury to you or others.
1. Do not exceed capacity shown on frame or lower hook block.
2. Do not use to lift people or loads over people.
3. Do not use unless the hoist’s frame and chain form a straight line between hooks.
4. Do not use if the frame is in contact with any object.
5. Do not use if the unit is damaged or malfunctions.
6. Do not use extension on lever. Use hand power only.
7. Do not use if chain is twisted, kinked or damaged.
WARNING
TURNING THE CAM WITH A LOAD ATTACHED WILL ALLOW THE LOAD TO RELEASE AND MAY CAUSE INJURY.
TO AVOID INJURY: NEVER TURN THE CAM WHEN THE HOIST IS UNDER LOAD.
INSPECT THE RS2 LEVER HOIST
Inspect the RS2 before each use and at specified intervals as directed in the inspection section (see next column).
LOAD LIMITER®
The operation of a RS2 Lever Hoist equipped with a Load Limiter is the same as described above. In fact, as long as you are pulling or lifting loads that are within the rated capacity of the hoist, the Load Limiter will not function and you will not notice any difference in operation. However, if attempting to pull or lift load that is approximately 20% greater than rated capacity, the Load Limiter will function.
MAINTENANCE
INSPECTION
To maintain continuous and satisfactory operation, a regular periodic inspection procedure must be initiated so that worn, damaged and missing parts can be replaced before the unit becomes unsafe. The frequency of inspection must be determined by the individual application.
The following list gives an inspection procedure for normal usage under normal conditions.
When the unit is subjected to heavy usage or dusty, gritty, moist or corrosive atmospheric conditions, shorter time periods must be assigned. Inspection must be made of all parts for unusual wear, corrosion or damage, in addition to those specifically mentioned in the schedule on page 5. Make certain that the unit is complete and contains all parts including hook latches and end ring.
Any parts that are deemed unserviceable must be replaced with new parts before the unit is returned to service. It is very important that the unserviceable parts be destroyed and properly disposed of to prevent their possible future use as a repair item. Use only Yale Hoist supplied repair parts as other parts may look the same but may not be to proper specifications.
