Air Supply
The air supply must be clean, free from moisture and lubricated to have good motor performance and life
expectancy. Foreign particles, moisture and lack of lubrication are the primary causes of premature motor wear and
breakdown.
The water separator, regulator, lubricator, and filter are installed as standard on the outboard end of the winch.

It is recommended that a lockable isolation pressure relief valve, set to 110 - 120 psig (7.6 - 8.3
bar), be installed in the air supply line as close to the winch as possible.

• Do not operate the winch without the water separator, regulator, lubricator, and filter.
• Warranty will be void if any part of the water separator, regulator, lubricator, and filter
system is not used and maintained properly.
Air Lines
Inside diameter of air supply lines must not be less than size specified in
. Before making final
connections, all air supply lines should be purged with clean, moisture free air or nitrogen before connecting to
main air inlet. Supply lines should be as short and straight as installation conditions will permit. Long transmission
lines and excessive use of fittings, elbows, tees, globe valves, etc. cause a reduction in pressure due to restrictions
and surface friction in lines.
3-Way Ball Valve
Refer to
. A 3-way ball valve is located at the air inlet to the winch. One inlet to the 3-way ball valve is
to be connected to the Main Air Supply. The other inlet is available to be connected to an auxiliary air source, as
needed for Emergency Lowering or Emergency Raising in the event of Main Air Supply failure. Position lever to
open inlet once auxiliary air has been connected.
Air Pressure Regulator
The air pressure regulator is install between water separator and filter. The regulator is preset and sealed at the
factory and has a protective cover to ensure no adjustment to regulator is made unless necessary.
Any adjustments shall be made by an
Ingersoll Rand
trained Service Technician or a

Air Line Lubricator
A lubricator is installed as standard on this winch. The lubricator should be replenished daily and set to provide 2 to
3 drops per minute of ISO VG 68 oil.
