Safety Summary
• Make sure that any hand signals used by ground
personnel are clearly defi ned 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. Refer to Parts Manual 599048W.
• Maintain a minimum of three (3) complete wraps
of wire rope on the drum for normal operation. It
may help to paint the last fi ve 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 loading
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 pages 1-4 and 1-5.
• 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 hydraulics:
»
Wear personal protective equipment, such as
gloves and safety glasses, whenever servicing
or checking a hydraulic system.
»
Assume that all hydraulic hoses and components
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
cardboard to check for hydraulic leaks.
»
Small hydraulic hose leaks are extremely
dangerous, 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.
