1.5 System Check (Continued)
Over-Center Valve / Counterbalance Valve
• Give smoothly controlled winch out when under load and to provide full dynamic braking. It must be
installed to hold full load.
• The Port A of over-center valve means the inlet port of oil from reservoir and the Port B meaning the
return port of oil to reservoir.
• Over-center valve is a standard accessory for the HW series winch.
Hydraulic Hoses
• The following hydraulic hoses are recommended for maximum efficiency of the hydraulic winch. The
bigger nominal bore hose, the better winch performance.
• All hose lengths are kept to a minimum because pressure and flow loss is increased as hose length
increases.
• Pressure and return lines in excess of 3.5 meter (11.5 feetv) should be compensated with an in-
crease in nominal bore size. Motor drain line pipe shall be rated at 1/4" BSP N.B.
Inlet line . . . . . . . . . . . . . . . . . . . . . . . 1 1/4" – 1 1/2" nominal bore (N.B.) from reservoir to pump
Return line . . . . . . . . . . . . . . . . . . . . . 1" (N.B.) from control to reservoir
Pressure hoses . . . . . . . . . . . . . . . . . . 1/2" (N.B.) from control valve to over-center valve
WARNING
ALWAYS use supplied hand saver cable strap whenever spooling winch rope in or out, during
installation or operation to avoid injury to hands and fingers.
2.1 Spooling in under Load
WARNING
NEVER exceed winch's rated line pull. Power-in the winch rope evenly and tightly on the drum.
This prevents the outer winch wraps from sinking into the inner wraps, binding and damaging
the winch rope.
NEVER touch winch rope or hook while someone else is at the control switch or during
winching operation.
Do not shock load the winch when spooling. Avoid shock loads when spooling by pulsing the control
switch to take up winch rope slack. Shock loads can momentarily far exceed the winch and rope ratings.
NOTICE
DO NOT power the hook into the fairlead. This could cause damage to the fairlead.
2.2 Stretching the Wire Rope
WARNING
ALWAYS pre-stretch rope and re-spool under load before use. Tightly wound rope reduces
chances of "binding", which can damage the rope.
NEVER operate winch with less than five (5) wraps of wire rope around the drum. Rope could
come loose from the drum, as the rope attachment to the drum is not designed to hold a load.
The goal of stretching your wire rope is to wrap it tightly on the winch drum so that it can support ad-
ditional layers of wire. It can take up to 1,000 lbs. to properly stretch large diameter cable. This can be
accomplished with a vehicle supplied as dead weight to stretch the rope. This is an exercise that will
make your wire rope last longer, avoid tangles and ensure a tightly wrapped winch. Use care to evenly
wrap each layer to prevent damage to the rope.
