pull the handle off the shaft. Pull the ratchet lever downward and feed the line off the drum by rotating the crank
handle in the "lower" direction. Route the line over the support structure pulley system.
TO RAISE A LOAD: Rotate the winch crank handle when using the low speed shaft or the high speed shaft. For
worker safety, the crank handle incorporates an overload clutch which limits the winch lifting force on the high
speed shaft to approximately 250 lb.. (113 kg) and 500 lb.. (227 kg) on the low speed shaft, thus reducing the
possibility of injury should a worker become entangled during retrieval. Do not exceed the rated capacity of 350
lb. (159 kg).
TO LOWER A LOAD: Rotate the winch crank handle in the "raise" direction until the ratchet brake lever can be
pulled down, then rotate the crank handle in the "lower" direction. When a load is suspended from the winch, use
caution when the ratchet brake lever is pulled down since the load will be transferred to the winch crank handle.
To prevent loss of control of the load, do not block or restrict the ratchet lever from engaging the teeth on the
drum, except by normal manual operation. If the operator fatigues, or for any reason desires to "hold" the load,
allow the ratchet brake to engage and support the load.
The Salalift® I winch is designed and typically used for manual operation. Certain situations where the speed of the
rescue, coupled with fatigue experienced by operator during long lifts, may necessitate the need for a powered drive
operation. Contact 3M for more information.

SALALIFT II WINCH (8102001 SERIES): Attach the winch to the support structure as described in section 3.3
(D). Install winch crank handle onto the input shaft by aligning the hub of the crank handle with the square drive
marked "winch shaft" and pushing firmly inward until handle snaps in place (the grip on the handle should face
outward). To release the crank handle from the shaft, pull the handle off the shaft. Feed the line off the winch drum
by rotating the crank handle in the lowering direction (counterclockwise). Apply slight tension to the line while
feeding it off the drum. Free-wheel mode may also be used, see FREE-WHEEL MODE below. Route the line over the
support structure pulley system.
TO RAISE A LOAD: Rotate the winch crank handle in the raise direction (clockwise). To hold or momentarily
suspend the load, stop cranking. The automatic clutch/brake will hold the load if handle is released. The winch
incorporates an overload clutch limiting the lifting force to approximately 700 lb.. (318 kg), reducing the chance
of injury if a worker becomes entangled during retrieval. Do not exceed the rated capacity of 350 lb. (159 kg).
TO LOWER A LOAD: Rotate the winch crank handle in the lower direction (counterclockwise). When lowering
line without a load, maintain slight tension on the line to aid payout.
FREE-WHEEL MODE: Remove the crank handle from the raise/lower input shaft. Reverse the crank handle and
install it onto the square drive marked "freewheel shaft" by aligning the handle hub with the shaft. See Figure
10. To engage free-wheel mode install winch handle onto Freewheel shaft as shown, rotate the crank handle (A)
counterclockwise until it stops and hold. The line can now be freely pulled off of the winch drum. To avoid build-
up of slack line on the drum, pull the line off the drum smoothly, remove slack on the drum by releasing the
crank handle and pulling on the line. If the line pays out too rapidly, an over speed brake will activate and lock,
stopping the line. If this happens, return to the winch mode and rotate the crank handle clockwise two turns
to unlock the over speed brake. Do not engage free-wheel mode with load on the lifting line, remove load on
the line before engaging free-wheel mode. When using the Salalift II for climbing protection applications, free-
wheel mode is not recommended. The operator must be attentive to slack line; paying out and reeling in line as
needed.
D.
IMPACT INDICATOR AND CABLE RESERVE: The Salalift II winch is supplied with a connecting swiveling hook that
incorporates a load indicator. This indicator functions if the winch is severely impact loaded or if the lifting capacity is
exceeded by a preset amount. See section 5.0 for inspection of load indicator. The Salalift II incorporates a reserve
cable retention feature on the cable drum. With the drum near empty (single layer of cable (Figure 13 A) remaining),
the shear pin (Figure 13 B) is visible. The reserve cable ensures that the shock absorbing feature is available
throughout the working range of the winch. If the winch is shock loaded at the reserve point of cable payout, the
shear pin will shear, allowing the shock absorber to function normally. If the shear pin has been sheared, the unit
must be returned for inspection and repair. See section 5.0 for inspection details.
;
Do not use winch for lifting or lowering of more than one person, except for emergency situations. In this case, if
using the 8101000 series, the low speed shaft must be used to prevent handle slippage. The maximum lifting force is
approximately 500 lb. (227 kg).
;
If the cranking tension eases during lowering, the person or material being lowered has reached a work level or
obstruction. Do not continue cranking without communicating with the person or checking the material being lowered.
Always keep the cable tension firm. Slack cable could cause a free fall.
;
A minimum of four wraps of line must remain on the drum at all times on the 8101000 series. One complete
layer of line must remain on the 8102001 series. Do not attempt to reverse wind the line onto the drum. Line must
wind onto the drum by turning the crank handle in the "raise" direction only. Check periodically to see that the line is
winding evenly on the drum. Use gloves when handling line.

INSPECTION
5.1
INSPECTION FREQUENCY: The Winch must be inspected at the intervals defined in Section 1. Inspection procedures
are described in the "Inspection and Maintenance Log" (Table 2). Inspect all other components of the Fall Protection
System per the frequencies and procedures defined in the manufacturer's instructions.
