Model FA7 GUIDELINE WINCH
This instruction and parts sheet covers the operation and adjustment of the Guideline controls for the FA7 winch. This sheet gives
authorized service personnel the information necessary to adjust the Guideline controls.
This sheet should be used in conjunction with the FA7 Parts, Operation and Maintenance Manual, form MHD56076.
FA7 Guideline winches are equipped with assemblies that are specific to guideline operation they are, drum locking assembly, guideline
control valve assembly, and reduction gearbox assembly.
Operators should familiarize themselves with these features, how they operate and any other safety procedures provided in the FA7
Parts, Operation and Maintenance Manual, form MHD56076.
Description of Operation
With the auxiliary valve selector lever in the Normal position,
the winch control valve-will provide normal winch operation.
With the auxiliary valve selector lever in the Guideline position,
the winch will automatically Haul-In wire rope to maintain
tension.
The auxiliary valve provides a preset air pressure to the air
motor and disc brake. This allows the brake to be released, and
the winch to Over-Haul during Guideline operations. In this
position the winch will maintain a constant tension on the
guideline while the load is being lowered.
The auxiliary valve is factory-set to maintain tension based on
the weight of 5000 ft. (1524 m) of 3/4 in. (19 mm) submerged
wire rope. See Regulator Adjustment section for adjusting
procedures.
Operation
Place the selector lever in Normal position and use the winch
control valve to position the end of the load line at the load.
Connect the load line to the load and
actuate
the control valve to
remove slack from load line.
l
If there is slack in the load line when the selector lever is
placed into GUIDELINE position, the wire rope will SNAP
tight as the winch automatically maintains tension.
Actuate the selector lever to Guideline position. The winch
will automatically Haul-In to maintain tension on load line.
When the load is at the work location, shift the selector lever to
Normal mode and lock the drum using the locking dog.
Locking Dog Operation
To engage locking dog, grab both grips on the locking dog handle
and pull outwards, rotate handle 90 degrees and allow handle to
return to the deep slots in cap. Pin will engage locking pin hole
in drum flange, locking drum in position. If pin does not line up
with locking pin hole in drum flange, use the winch control valve
to slowly rotate the drum to the NEAREST locking position on
drum.
To disengage locking dog, grab both grips on the locking dog
handle and pull outwards, rotate handle 90 degrees and allow
handle to return to the shallow slots in cap.
The regulator (721) on bracket (742) is factory-set at about 50
psig (3.5 Bar/349 kPa). This will maintain a tension of 4500 lb.
(2045 kg) on the load line. If thiS setting is not adequate (i.e. wire
rope tension is not being maintained), increase the regulator
pressure.
Ensure that winch control valve is locked in the neutral position
and that selector lever is in the Normal position.
