3. Press UP button (slow speed) and remove all
slack in load chain. Increase tension in load
chain until hoist is about to raise the load.
4. Check again that load is properly slung, is
directly under hoist, and will not suddenly swing
or twist.
5. Raise load an inch or two above ground and
stop. Observe load for a few moments, looking
for signs that load or hoist system is unstable,
or other indications of a problem.
6. Check that chain is not twisted at bottom hook.
All welds should face same direction (see
Figure 11-1). For hoists with two or more falls of
chain, make sure bottom hook is not capsized.
This may cause the chain to twist.
7. Raise load to traveling height. Raise only to
height necessary to safely clear all obstacles.
8. Lower load at destination. If both UP and
DOWN commands must be used during
lowering, pause for a moment between each
reversal of load direction.
9. Slowly allow weight to shift from hoist to ground
or new support. Do not approach load until all
tension is out of chain and load is stable.
10. Press red stop button to lock out hoist
movement until load has been unhooked.
11. Always leave bottom hook and pendant controls
in a vertical, static position, never in a position
that can produce swing or slip.
12.3 Magnetic brake function
The magnetic disc brake provides dependable and
rapid stops, and produces less wear on parts than
standard mechanical braking systems. It also
provides an important safety measure – a power
failure will result in immediate engagement of the
brake.

13.1 Replacing load chain
Over time, the load chain will wear or elongate. This
can cause damage to hoist, breakage, or non-
engagement of the load sheave. The following
procedures describe replacing the load chain for
single and multiple fall hoists. These procedures
must be performed by qualified persons only.
It is recommended that after installing new chain,
the first few lifts be limited to no more than 25-50%
of rated load capacity. Thoroughly inspect new
chain for twist before placing hoist into routine
service.
IMPORTANT: Due to the internal space of hoist,
additional length must be added to the nominal
chain length, as shown in Table 4. For example,
model TS050 with 10 ft. lift requires 11.65 ft. of chain.
Model
Additional length of chain
TS050
1.65 ft.
TS100
1.65 ft.
TS200
2.64 ft.
TS300
5.28 ft.
TS500
5.28 ft.

13.1.1 Cutting chain
Use eye/face protection when
cutting chain.
Use a bolt cutter with special cutter jaws for cutting
hardened chain. Cut only one side of the link at a
time. When making the second cut, place a mat over
the chain to catch the flying chain section.
13.1.2 Single fall chain hoist
1. Locate the flexible chain puller that was
provided with your hoist.
2. Lower the load hook until only 1 to 2 feet of
slack chain remains in the chain container.
3. Remove chain container.
4. On the slack end of the chain, remove the chain
stop, spring, and limit block (Figure 13-1). Keep
these handy for later re-installing.
