6. Winch Cable (wire rope)
Inspect entire length of wire rope, chokers and hooks
according to wire rope and rigging manufacturers recom-
mendations.
7. Mounting Fasteners
Check/tighten all winch mounting fasteners to recom-
mended torque after the first 100-250 hours of operation,
then every 1000 operating hours or six (6) months,
whichever occurs first.
8. Warm-Up Procedure
Start tractor engine and operate at low idle for five min-
utes.
Shift the control lever to the freespool position (if
equipped). Then, with the tractor engine at low idle, place
Power Shift lever in Reel-In (forward) position. The winch
gear train will rotate and warm the oil to operating tem-
perature.
If not equipped with Free Spool, operate winch alternate-
ly in Reel-Out and Reel-In with little or no load to warm
the oil and lubricate the gear train.
A warm-up procedure is recommended at each start-up
and is essential at ambient temperatures below +40°F
(4°C). Failure to warm-up winch hydraulic system may
result in erratic clutch/brake operation which may result
in property damage, injury or death.
Do not shift Freespool lever and attempt to engage
cable drum while the cable drum or gear train is rotat-
ing. Winch gear train damage may result.
CAUTION
Basic Oil Requirements
15,000 SUS maximum allowed viscosity at cold start-up; requires extended equipment warm-up. 3,000 SUS maxi-
mum allowed viscosity at cold start-up; requires normal equipment warm-up. 60 SUS minimum allowed viscosity at
maximum winch operating temperature, assuming ambient plus 80°F (27°C).
Oil must possess high temperature oxidation stability, rust corrosion protection, good dispersant and detergent char-
acteristics, anti-wear additives and remain compatible with nitrile base seals.
RECOMMENDED OIL
We have published the following specifications to help you determine which lubricant is best suited to your application.
Your lubricant supplier should assure you his product meets this specification. If there is any doubt as to the suitabil-
ity of a lubricant, contact the Carco Winch Service Department, providing a detailed copy of the product specifications.
Cold start-up in this ambient temperature range requires extended equipment warm-up to prevent erratic
clutch and brake operation which may result in property damage, injury or death.
