1. Read all warning tag information and become familiar
with all controls
BEFORE operating the winch.
2. Never attempt to clean, oil or perform any mainte-
nance on the winch with the tractor engine running,
unless specifically instructed to do so in this manual.
3. Before starting the tractor engine, be certain all con-
trols move freely and are placed in the "Brake On"
(neutral) position.
4. Never operate the winch controls unless you are
properly seated at the operator's station on the trac-
tor and you are sure all personnel are clear of the
work area.
5. Never attempt to handle winch cable when the hook
end is not free. Keep all parts of body and clothing
clear of winch drum, cable rollers and entry area of
fairleads and arches.
6. Ground personnel should stay in clear view of the
tractor operator and clear of the winch drum. Do not
allow ground personnel near a winch line under ten-
sion. A safe distance of 1 ½ times the working length
of the cable should be maintained. Never allow any-
one to stand under a suspended load.
7. Avoid sudden "shock" loads or attempting to "jerk" a
load free. This type of operation may cause heavy
loads in excess of the rated winch capacity, which
may result in the failure of the cable and/or winch.
8. Use only GENUINE CARCO parts. Do not use parts
from other winch manufacturers on your CARCO
winch. Do not use CARCO parts on winches from
other manufacturers.
9. Use the correct size ferrule for the cable and pocket
in the winch drum. Never use knots to secure or
attach cable to the winch drum, or the hook to the
cable. The cable anchor or ferrule pocket in the cable
drum is designed to provide a self release in the
event a back-sliding load must be released from the
tractor in an emergency situation. The cable anchor
or ferrule alone will NOT support the rated capacity of
the winch. Therefore, a minimum of five (5) complete
wraps must be maintained on the winch drum.
NOTE: We suggest painting the last five wraps of
cable bright red to serve as a visual warning.
RECOMMENDED OPERATING PRACTICES
1. Leather gloves should be used when handling winch
cable.
2. Operate the winch to match line speeds to job condi-
tions.
3. Assure that personnel who are responsible for hand
signals are clearly visible and that the signals to be
used are thoroughly understood by everyone.
4. Inspect winch cable, rigging, winch and tractor at the
beginning of each work shift. Defects should be cor-
rected immediately.
5. Position the tractor for the straightest line of pull to
reduce the wear on the winch cable and ensure even
spooling.
6. When winding winch cable on the winch drum, never
attempt to maintain tension by allowing the winch
cable to slip through the hands. Always use the
"hand-over-hand" technique, being careful to keep
hands and clothing away from winch drum and fair-
lead rollers.
7. Be sure of tractor ground stability before winching in
a load.
8. Store unused chokers, slings and rigging in a neat
and orderly fashion to prevent damage to equipment
or injury to personnel.
9. Do not operate the winch under loads that exceed the
maximum rated bare drum line pull. If excessive
loads are encountered, use a multi-part line and
sheave blocks. Any attempt to exceed the capacity of
one winch (such as coupling 2 or more tractors
together) is extremely hazardous.
10. The factory approved adaptions for CARCO winches
are designed and intended for use on specific models
of crawler tractors. Changing winches between trac-
tors is not possible in some cases because of differ-
GENERAL SAFETY RECOMMENDATIONS
Safety for operators and ground personnel is of prime concern. Always take the necessary precautions to ensure safe-
ty to others as well as yourself. To ensure safety, the tractor and winch must be operated with care and concern by the
operator for the equipment, and a thorough knowledge of the machine's handling and performance capabilities. The
following recommendations are offered only as a guide for the operator. Local rules and regulations will also apply.
Failure to obey the following safety recommendations
may result in property damage, injury or death.
