Yale RS2 manual Attaching to Load, To Pull or Lift Load

Page 7

4.Pull on hook side and loose end side of load chain to make sure chain feeds freely into and out of the hoist.

5.Grasp unit by frame or upper hook and pull on end ring or lower hook to pull the chain through hoist to the length required to attach lower hook to load. Pull on end ring to take-up slack in chain and THEN LET GO OF END RING.

6.Rotate the cam counterclockwise (to left) until the arrow points to “operate”.

7.Pull sharply on the loose end of chain and THEN LET GO OF CHAIN. Pull sharply on the lower hook side of chain, to make sure gearing is fully engaged.

 

 

 

 

WARNING

 

 

 

 

 

 

 

 

 

FAILURE TO FULLY ENGAGE THE GEARING WILL

 

 

 

ALLOW LOAD TO RELEASE AND THUS CAUSE INJURY

 

 

 

 

 

TO AVOID INJURY:

 

 

 

AFTER ROTATING CAM KNOB TO “OPERATE”, PULL

 

 

 

EACH CHAIN SHARPLY TO RE-ENGAGE GEARING AS

 

 

 

DIRECTED ABOVE.

 

 

 

8. The hoist is now ready for operation. Move trigger to “UP”

 

 

 

 

 

position and operate lever in and up and down motion to

 

shorten the distance between hooks and thus pull or lift

 

load. Only move the load enough to slightly load the hoist.

 

not

Check free-play of cam knob. The arrow tip should

 

 

move more than 3/16 inch (4.7mm). If

 

movement is

greater than this, move trigger to

 

“DN” position and

operate the

 

lever to remove the load. Repeat step 7 and if

 

the free-play is still more than 3/16 inch (4.7mm), the hoist

 

should be disassembled to check for damaged or worn

 

parts. Do not take up the load chain to the point where

 

the

end ring or lower hook block becomes jammed

 

against

 

the frame.

ATTACHING TO LOAD

Attach the lower hook to the load so that it is seated in the bowl of the hook and is not bearing against the tip of the hook, and the latch is tight against the hook tip.

WARNING

ALLOWING THE LOAD TO BEAR AGAINST THE HOOK LATCH AND/OR HOOK TIP CAN RESULT IN LOSS OF LOAD.

TO AVOID INJURY:

DO NOT ALLOW THE LOAD TO BEAR AGAINST THE HOOK LATCH AND/OR HOOK TIP. APPLY LOAD TO HOOK BOWL OR SADDLE ONLY.

Do not wrap the load chain around the load and hook onto itself as a choker chain sling or bring the load in contact with the hoist. Doing this will result in the loss of the swivel effect of the hook which could cause twisted chain and a jammed liftwheel. Also, the chain may be damaged at the hook. Make sure the upper and lower hooks are in a straight line and the frame is free to swivel on the upper hook. If the proposed use prevents straight line attachment, use an Anchor Sling (see page 1) or a chain sling to obtain a straight line pull.

WARNING

IF THE UNIT IS NOT RIGGED IN A STRAIGHT LINE HOOK TO HOOK MANNER, AND IF THE FRAME IS NOT FREE TO SWIVEL, LEVER PULL MAY BREAK FRAME AND CAUSE PHYSICAL INJURY AND LOSS OF LOAD.

TO AVOID INJURY:

RIG THE UNIT IN A STRAIGHT LINE HOOK TO HOOK MANNER AND KEEP FRAME FREE TO SWIVEL - SEE BELOW.
