TEST WINCH PERFORMANCE by operating the winch with a test load
not exceeding the load rating.
• Listen for unusual noises, and look for signs of damage as you operate the
winch.
• Make sure the wire rope winds evenly and tightly onto the drum. If it is
loose or uneven, rewind it before continuing.
• Make sure the load moves smoothly, without hesitation or strain.
• Make sure the winch responds to the control device. It must rotate as shown
on the control labels, and it must turn off when you release the control.
• Check the brake. Raise the load, then lower it and stop it a few feet off
the ground. If the load continues to coast or creep under normal operating
conditions, contact the factory.
Completely correct all problems before continuing. Use the
Troubleshooting Chart to help determine the cause of certain problems.
See Table 3.
3.3.4
Instructions for Periodic Inspection, See Table 2.
a
VISUALLY INSPECT the winch and all other equipment.
• Disassembly may be required in order to properly inspect individual
components. Contact factory for assembly/disassembly instructions.
Disassembly before contacting Thern, Inc. voids all warranties.
• Check the finish for wear, flaking, or other damage.
• Check all equipment for cracks, dents, bending, rust, wear, corrosion and
other damage. If the equipment was overloaded, or if you notice cracks
and other signs of overloading and damage, promptly remove equipment
from use and have it repaired or replaced.
DO NOT CONTINUE TO USE
DAMAGED OR OVERLOADED EQUIPMENT OR WIRE ROPE.
• Check all fasteners for stripped threads, wear, bends, and other damage.
• Check all fasteners for proper torque levels. Some fasteners will require
disassembly of the winch in order to inspect and retorque.
• Check the reducer and motor for signs of leakage.
• Make sure the motor breather plug is clean, open and installed correctly.
• Make sure all labels and plates are readable, firmly attached, free of
damage and clean. Replacements are available from the factory.
b
DRAIN A SMALL AMOUNT OF LUBRICANT from the motor into a clean
container.
• Check the lubricant for dirt, metal particles, water, and other signs of
contamination. Completely drain the motor if lubricant is contaminated.
• Make sure the winch is completely lubricated. See section 3.2 -
Lubricating the Winch.
c
INSPECT THE TRAVEL LIMIT ASSEMBLY
Note: Pneumatic rotary travel limits need periodic inspection to verify
accurate operations and ensure there are no damaged or loose components.
• REMOVE guard covering rotary limit switch.
• ENSURE drive gears are meshing correctly and are free of damage.
Visually inspect enclosure for damage such as cracks or chips.
Important!
• Start an inspection program as
soon as you put the winch into use.
• Appoint a qualified person to
be responsible for regularly
inspecting the equipment.
• Keep written records of
inspection. This allows
comparison with comments from
previous inspections so you
can see changes in condition or
performance.
• Make sure all labels and plates
are readable, firmly attached,
free of damage and clean.
Replacements are available from
the factory.
Perform frequent inspections:
• Before each operation.
• Every 3 hours during operation.
• Whenever you notice signs of
damage or poor operation.
Perform periodic inspections:
• Every 12 months except for as
noted below.
• Whenever there is noticeable
damage, loose fasteners, or
poor operation during frequent
inspection.
• Whenever you return the winch
to service from storage.
• Whenever the winch has, or may
have been, overloaded or shock
loaded.
