Air Line Lubricator
Refer to Dwg. MHP0191.
Always use an air line lubricator with these motors. The
lubricator must have an inlet and outlet at least as large as the
inlet on the motor directional control valve. Install the air line
lubricator as close to the air inlet on the motor as possible.
CAUTION
• Lubrication for the FA2A motor must be provided in the
supply air. Ensure an inline lubricator is installed before
operating the winch motor.
• Lubricator must be located no more than 10 ft. (3 m)
from the motor.
• Shut off air supply before filling air line lubricator.
The air line lubricator should be replenished daily and set to
provide 3 drops per minute of ISO VG 32 (10W) oil.
Air Line Filter
Refer to Dwg. MHP0191.
Place the strainer/filter as close as practical to the motor air inlet
port, but upstream from, the lubricator, to prevent dirt from
entering the motor. The filter/strainer should provide 20 micron
filtration and include a moisture trap. Clean the filter/strainer
periodically to maintain its operating efficiency.
(Dwg. MHP0191)
Air Pressure Regulator
Refer to Dwg. MHP0191.
If an air pressure regulator is used, install between the lubricator
and filter as shown in Dwg. MHP0191.
Moisture in Air Lines
Moisture that reaches the air motor through air supply lines is a
primary factor in determining the length of time between service
overhauls. Moisture traps can help to eliminate moisture. Other
methods, such as an air receiver which collects moisture before
it reaches the motor, or an aftercooler at the compressor that
cools the air to condense and collect moisture prior to
distribution through the supply lines are also helpful.
Mufflers
Make sure mufflers are installed in winch exhaust manifold and
control valve exhaust port. An additional muffler is used on
winches equipped with an emergency stop and overload device.
Check mufflers periodically to ensure they are functioning
correctly.
Motor
For optimum performance and maximum durability of parts,
provide a lubricated air supply of 380 scfm (10.8 cu. m/min) at
90 psig (6.3 bar/630 kPa). The air motor should be installed as
near as possible to the compressor or air receiver. Recommended
pressures and volumes are measured at the point of entry to the
air motor directional control valve.
Initial Winch Operating Checks
Winches are tested for proper operation prior to leaving the
factory. Before the winch is placed into service the following
initial operating checks should be performed.
1.
When first running the motor inject some light oil into the
inlet connection to provide initial lubrication.
2.
When first operating the winch it is recommended that the
motor be driven slowly in both directions for a few
minutes.
For winches that have been in storage the following start-up
procedures are required.
1.
Give the winch an inspection conforming to the
requirements of “Winches Not in Regular Use” in the
“INSPECTION” section.
2.
Pour a small amount of ISO VG 32 (10W) oil in the motor
inlet port.
3.
Operate the motor for 10 seconds in both directions to flush
out any impurities.
4.
Check to ensure oil levels are “full”.
5.
The winch is now ready for normal use.
