• Lubricator must be located no more than 3 m (10 ft.) from the winch motor.
• Shut off air supply before filling air line lubricator.
FA2A: Refer to 'FA2A Motor Lubrication' in the "LUBRICATION" section.
FA2.5A/FA5A: The air line lubricator should be replenished daily and set to provide 6 to 9 drops per minute of ISO VG 32 oil.
Air Line Filter
It is recommended that an air line strainer/filter be installed as close as practical to the motor air inlet port, but before the lubricator, to
prevent dirt from entering the valve and motor. The strainer/filter should provide 20 micron filtration and include a moisture trap. Clean the
strainer/filter periodically to maintain its operating efficiency.
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 after-cooler at the compressor that cools the air prior to distribution through the supply lines are also helpful.
Mufflers
Make sure mufflers are installed in winch and valve exhaust ports. Ensure mufflers are not damaged.
Motor
For optimum performance and maximum durability of parts, provide an air supply of 6.3 bar/630 kPa (90 psig) at the flow recommended in
the "SPECIFICATION" section, as measured at the motor inlet. 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.
• Do not exceed the maximum specified operating pressure, 6.3 bar/630 kPa (90 psig). The winch overload valve will exhaust air if
maximum pressure is exceeded.
Initial 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 some light oil should be injected into the inlet connection to allow good 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 oil in the motor inlet port.
3.
Operate the motor for 10 seconds in both directions to flush out any impurities.
4.
The winch is now ready for normal use.
The four most important aspects of winch operation are:
1.
Follow all safety instructions when operating the winch.
2.
Allow only people trained in safety and operation of this winch to operate the winch.
3.
Subject each winch to a regular inspection and maintenance procedure.
4.
Be aware of the winch capacity and weight of load at all times.
• The winch is not designed or suitable for lifting, lowering or moving persons. Never lift loads over people.
• Winches equipped with a disengaging clutch are designed for pulling applications only. Do not use these winches in lifting
applications.
Daily Winch Setup
When air flow to the winch is interrupted, the emergency stop valve automatically activates. The winch will not operate until the emergency
stop valve is reset. Use the following procedure to prepare the winch for operation on a daily basis.
1.
Open all valves between the compressor or air receiver and the winch.
2.
Reset the emergency stop valve as described in 'To Reset Emergency Stop Valve' in this section.
3.
The winch is ready to be operated.
Winch Controls
A spring loaded, motor mounted, pilot air manual throttle control valve is supplied as a standard feature on the winch. Optional remote
throttle controls may be available on some models. Reference the model code on the winch nameplate and compare it to the sales brochure to
determine your configuration. The throttle controls provide operator control of the motor speed and direction of drum rotation.
Winch Mounted Air Throttle (standard feature)
(Refer to Dwg. MHP0699 or MHP1143)
The winch mounted throttle lever prevents accidental operation by locking in the neutral position when released. To operate, the control
throttle handle must be lifted up prior to being shifted in the desired direction. To control winch direction move the control throttle handle, as
viewed from the motor end, to the right (clockwise) to pay out wire rope and to the left (counterclockwise) to haul in wire rope. Refer to the
attached label. To ensure smooth operation of the winch avoid sudden movements of the control valve.
