Now, insert the suspension screws through the holes in the
adapter and hand thread these into the self locking nuts
enclosed in the hoist frame. The screws will turn freely into
the nut until the last 1/4” (6.35mm) of travel during which
the resistance of the nut locking collar will be encountered.
Securely tighten the screws to the recommended seating
torque (see Table 2) using a 12 point socket which fits the
head of the screw.
The dead end of the load chain is temporarily positioned (a
few links from the end) by a wire tie. Do not remove this tie
before attaching the chain to the dead end block. (See Fig.7).

ATTACHING LOAD CHAIN
The Model R & RR are shipped with the dead end of the load
chain temporarily connected to the bottom of the hoist by a
wire tie (1) as shown in Figure 7. The clip is located a few links
from the end of the chain, and it should not be removed until
the chain is to be attached to the dead end block (2). To attach
the chain to the dead end block, proceed as follows:
1. Suspend the hoist from an adequate support.
2. The hoist is shipped with the dead end of the load chain
temporarily positioned a few links from the end by a light
wire clip (1) as shown in Figure 7. Do not remove this clip
until the chain is secured.
3. Remove the clip (1) by inserting a screw driver blade
through a chain link and levering against the bottom of
the hoist. Slide the contact block up the chain until it is
against the bottom of the hoist and the dead end block is
projecting through the square opening in the bottom of
the block. Insert the last link of the load chain, making
sure there are no twists between the hook block and the
dead end block, into the dead end block. Push the
contact block up slightly and secure the load chain to the
dead end block using the dead end pin, washer and
cotter pin furnished with the suspension. The dead end
pin also supports the contact block (See Figure 8).
4. Do not remove the wire ties from the load chain at this
time.

W WA AR RN NIIN NG G
Using other than CM supplied high strength suspension
screws to attach the suspension adapter to the hoist may
cause the screws to break and allow the hoist and load to
fall.
TO AVOID INJURY:
Use only the CM supplied suspension screws to attach the
suspension to the hoist and hand torque these screws to
the recommended seating torque as specified above.
DO NOT apply any type of lubricant to the threads of these
screws. Lubricating the threads will reduce the effort to seat
the screws and as a result, tightening the screws to the above
recommended torque may break the screw, damage the sus-
pension adapter, strip the nuts and/or damage the hoist
frame.
