Safety Summary
General Safety Notices
The following pages contain general safety warnings
which supplement specific warnings and cautions appear-
ing elsewhere in this manual. All electrical and hydraulic
equipment is dangerous. You must thoroughly review

to operate, troubleshoot or service this winch.
The following symbols/terms are used to emphasize safety
precautions and notices in this manual:
DANGER
The “DANGER” symbol indicates a hazardous
situation which, if not avoided, will result in
death or serious injury. Carefully read the
message that follows to prevent serious injury
or death.
The “WARNING” symbol appears wherever
incorrect operating procedures or practices
could cause serious injury or death. Carefully
read the message that follows to prevent seri-
ous injury or death.
The “CAUTION” symbol appears where a
hazardous situation which, if not avoided,
could result in minor to moderate injury and
equipment damage.
This signal word alerts to a situation that is
not related to personal injury but may cause
equipment damage.
NOTE: …
The term “NOTE” highlights operating pro-
cedures or practices that may improve
equipment reliability and/or personnel per-
formance.
Safety Summary
Safety Regulations
Each country has its own safety legislation. It is in the
operator’s own interest to be conversant with these regu-
lations and to comply with them in full. This also applies
to local bylaws and regulations in force on a particular
worksite.
Should the recommendations in this manual deviate from
those in the user’ country, the national regulations should
be followed.
NOTE: All possible safety hazards cannot be
foreseen so as to be included in this manual.
Therefore, you must always be alert to poten-
tial hazards that could endanger personnel
and/or damage the equipment.
The winch shall not be used for hoisting.
Use hearing protection when operating
winches.
Winch protected with internal pressure relief
valves set to 3500 psi max.
Operation, Inspection, and Maintenance Warnings
Obey the following cautions and warn-
ings before using your winch to avoid
equipment damage, personal injury or
death.
• Do not operate the winch unless you are authorized
and trained to do so.
• Do not operate the winch unless the vehicle is
equipped with a screen to protect the operator if
the wire rope breaks.
• Read, understand, and follow the operating, inspec-
tion, and maintenance instructions in this Operating
Manual.
ii
• Do not use the control levers for hand holds when
entering or leaving the vehicle.
• Do not permit other people near the control area
when you inspect or repair a machine.
• Never inspect, repair, or perform maintenance on
a machine that is in motion.
• Inspect the winch before each use:
»Make sure that the controls and instruments
operate correctly.
»Report the need for repairs immediately.
»Do not work with a damaged or worn wire
rope.
»Do not use a winch that needs repairs.
»If the wire rope and ferrule must be removed
from the drum, make sure the end of the wire
rope and ferrule are controlled when the ferrule
is released. The end of the wire rope can sud-
denly move from the drum like a compressed
spring when the ferrule is released and cause
an injury.
• Stay in the operator’s seat when operating the
winch.
• Do not stand on the vehicle when operating the
winch.
• Avoid winch operation near people or other ma-
chines.
• Never stand nor permit others to stand in the bight
(loop) of a wire rope.
• Do not stand nor permit others to be near the
winch or wire rope when there is tension on the
wire rope.
• Observe jobsite rules.
• Be in complete control at all times.
• Do not use the control levers as hangers for clothes,
water bags, grease guns, lunch pails, etc.
• Do not leave the vehicle when the winch wire rope
is under tension.
• Do not permit riders on the vehicle or load.
• Do not use the winch as an anchor for a double or
two-part line.
• Do not pull the hook through the throat or over the
drum, which will cause damage.
• When the winch is not in use, make sure the control
lever is in BRAKE-ON position and the winch brake
is applied.
• Do not use winch as a hoist. Tractor and skidder
mounted winches are designed for towing.
• Always inspect wire rope, tail chain and other rigging
components for wear, damage, broken strands or
abuse before use.
• Never use wire rope, tail chain or other rigging that
is worn-out, damaged or abused.
• Never overload wire rope, tail chain or rigging.
• Wire rope and tail chain will fail if worn-out, over-
loaded, misused, damaged, improperly maintained
or abused. Wire rope or tail chain failure may cause
serious injury or death!

• Do not terminate wire rope to tail chain by the use
of a knot.
• Do not handle wire rope if the hook end is not free.
A load could break away, suddenly tensioning the
wire rope, resulting in serious injury or death.
• Stay clear of wire rope entry areas (fairlead or arch
rollers, winch drum etc).
• Make sure ground personnel are in plain view of the
operator, and at a distance of at least 1½ times the
working length of the wire rope.
iii
Safety Summary
• Make sure that any hand signals used by ground
personnel are clearly defined and understood by
everyone involved.
• Do not attempt to “jerk” or “shock” a load free. Doing
so can cause loads in excess of the rated capacity
of the wire rope, winch, or mounting hardware.
• Replace any parts only with genuine Allied Winch
parts.
• Maintain a minimum of three (3) complete wraps
of wire rope on the drum for normal operation. It
may help to paint the last five (5) wraps of wire rope
a contrasting color, to serve as a visual indicator.
• Do not handle wire rope with bare hands. Wear
leather gloves at all times.
• Align the tractor with the load to prevent side load-
ing the winch, and to maintain even spooling of the
wire rope.
• If applying tension to the wire rope manually during
spooling:
»Ensure that the operator is winching in slowly,
»Keep your hands and clothing well clear of any
rollers or the winch drum,
»Do not maintain tension by letting the wire rope
to slip through your hands,
»Use a hand-over-hand technique to maintain
tension.
• Be aware of the ground conditions, and make sure
the ground and tractor are stable enough to pull
the intended load.
• Do not attempt to pull loads in excess of the rated
capacity of the winch.
• Keep yourself informed of any applicable codes,
regulations and standards for the job.
• Your winch may have temperature shut-off system
for protection of tractor and winch. Manual override
of high temperature shut-off will cause damage to
tractor and winch.
• This winch is neither intended, designed, nor rated
for any application involved in the lifting or moving
of personnel.
• Use only the lubricants listed in the Recommended
Oil List. See Page 3-1 in Section 3.
• Do not weld on any part of the winch. Contact Allied
Systems if weld repairs are needed.
• The hydraulic system must be kept clean and free
of contamination at all times.
• Be aware of the hazards of pressurized hydrau-
lics:
»Wear personal protective equipment, such as
gloves and safety glasses, whenever servicing
or checking a hydraulic system.
»Assume that all hydraulic hoses and compo-
nents are pressurized. Relieve all hydraulic
pressure before disconnecting any hydraulic
line.
»Never try to stop or check for a hydraulic leak
with any part of your body; use a piece of card-
board to check for hydraulic leaks.
»Small hydraulic hose leaks are extremely dan-
gerous, and can inject hydraulic oil under the
skin, even through gloves.
»Infection and gangrene are possible when
hydraulic oil penetrates the skin. See a doctor
immediately to prevent loss of limb or death.
