Inspection:
Digital Winch
Inspect all screws, bolts and nuts. Ensure they are securely attached and tight. Check to see if
(Figure 2)
any bolts, nuts or other parts are missing, or have been substituted or altered in any
way. Inspect covers and housings. Ensure they are free of cracks, dents, corrosion, or other
damage.
Labels (Figure 15)
Verify that all labels are securely attached and are legible.
Fall Protection
Additional Fall Protection equipment that is used with the product should be installed and
Equipment
inspected per the manufacturer instructions.
Crank Handle Screws
Removable Crank Arm must lock positively into each of the drive hubs and be free of cracks,
bends, or other damage. Check that each handle on the crank arm is tight. Use Loctite262 or
equivalent thread lock on the anchor screws if required to keep
them tight. Do not use unless the crank arm is fully functional.
Connecting Hook
Connecting hook must not be damaged, broken, distorted, or have any sharp edges, burrs,
cracks, worn parts, or corrosion. Ensure the connecting hook works properly.
Hook gate must move freely and lock upon closing. Hook must swivel freely.
Brake Wear
Inspect the Brake Wear Indicator located in the center of the 4:1 Drive Hub. If the indicator
Indication (Figure
is in the red section, remove the Winch from service and return to 3M or an authorized repair
11A)
center service.
Digital Counter
If the digital counter exceeds 10,000 cycles from the last factory service recorded in the
(Figure 11B)
inspection log, return the winch to 3M or an authorized repair center for service.
Wire Rope Flaws
Inspect entire length of wire rope assembly starting at the hook. Always wear protective gloves
when inspecting wire rope. Inspect for broken wires by passing the wire rope through gloved
hands, flexing it every few inches to expose breaks. Inspect for kinks, cuts, crushed burned
areas, corrosion, or other damage. Wire rope with serious damage must be removed from
service.
Synthetic Rope
Inspect for concentrated wear, frayed strands, broken yarns, cuts, and abrasions. The line must
be free of knots, excessive soiling, heavy paint buildup, and rust staining throughout its
length. The line must be free of ultraviolet damage, indicated by discoloration and the presence
of splinters and slivers on the rope surface. All of the above factors are known to reduce rope
strength. Damaged or questionable rope must be replaced by an authorized service center.
Rope
Verify the rope is fully seated in the Drum by raising and lowering a load of at least 100 lb.
(35 kg). If the rope slips during this operation, apply tension to the free end of the rope while
raising the load until slippage is eliminated.
