1. Important Information
The present Installation Manual contains important information for the
correct use of 2 Speed Hydraulic XT winches and you are therefore
advised to read it carefully before using the product.
The present manual gives technical information for the installation and
the maintenance of the following XT winch models:
XT66HD, XT70HD: Hydraulic Winch Vertical. These models are
equipped with a vertical drive hydraulic motor directly connected to
the winch through the disengagement box.
Hydraulic winches retain two speeds both in manual use (inverting the
direction of rotation of the handle) and in hydraulic use (pressing one
of the two control buttons).
It is of fundamental importance to be able to choose the most suitable
speed for the manoeuvre that you want to perform; this allows fast
recovery of the first part of the manoeuvre and more careful regulation
in the final stage.
In hydraulic winches the speeds are higher than in manual use even if,
at maximum load, a speed reduction up to 30% must be considered.
Speed
Simply insert the handle to disconnect the speed reducer-motor unit.
For Greater Safety: accidental starting of the motor does not affect
the winch, avoiding dangerous turning of the handle.
For Greater Efficiency: the speed reducer-motor unit does not turn in
manual use, avoiding needless friction.
Use
Winches are fitted with hydraulic motors as described in the table at
p.6. The winch speed is proportional to the flow and the winch load is
proportional to the pressure.
Power
Antal powered winches come supplied with a chrome - plated bronze
drum. Black anodized aluminium drums are available on request, in
this case the aluminium drum is “reinforced” applying a special toothed
crowngear of high resistance alloy or chromed bronze.

2. Power Unit
The power unit refers to the
system indicated in the figure
below.
We herewith give some
indicationsonthecomponents
included in the Power Unit to
be supplied by the customers.
Power Units shall
serve the winch with a
pressure of 100-120 bar,
depending on the model
(check the table at p.3)
have a flow of 7,5 - 30 L /
min
connect to the winch with
3/8” inches pipes.
Power Unit
Switches - Mod. 251.035
Two switches are needed to activate the two speeds of each winch;
these are conventionally the red one for the first and the grey one for
the second speed.
Although the microswitch is protected by a watertight diaphragm,
the stainless steel ring nut is provided with a seat for sealant; more
sealant must also be put in the hole through which the electric wire
passes.
Power Unit is not supplied
by Antal.

Line Recovery Speed
Recovery speed are indicative values, theoretically calculated without
considering the real installation moreover a speed reduction has to
be considered in the presence of load about 30% reduction under the
max load.
*For Mod. W70 the six holes on the skirt for the anchoring screws are not equidistant one from the other.

1Opening the Winch
First of all, unscrew the upper
ring (R) with the provided key
(K). Thus lift the drum (D).
Finally unscrew the F1 screw
to lift the base (B) and access
the anchoring holes on the
skirt (S) of the winch.

Disassemble the new Winch
XT-HD:
It is not necessary to remove
the Motor Unit from the flange
(F), you can install the XT-HD
anyhow.
Install XT-HD
Drill the deck:
Drill the deck (Ø = 140 mm) to
let the Motor-Unit altogether
through the deck.
Thus, screw the F3 screws to
fix the skirt (S) onto the deck.
XT-HD Installation:
Fix the base (B) by screwing
in the F1 screws. Complete
by inserting the Drum (D),
proceeding as for the opening
of the winch, in reverse order.

Winch Assembly
Reassemble the winch, inverting the operations described above in
points 2 and 1. Fix the motor unit to the sub-base, tighten the 8 scews
F2 so that the Motor Unit matches perfectly to the flange (F).
4
Ensure that the drainege holes of the sub-base are facing in the right
direction.
Seal the holes for the anchoring screws and the join between the
skirt and the deck with silicone.
Lubrication
During assembly all the steel screws and washers must be generously
greased to avoid corrosion phenomena in the areas in contact with
aluminium parts.
Antal supplies a special Teflon grease for marine applications:
“TLF400” in 100 gr packs.
This product is an excellent lubricant and ensures lasting protection of
the aluminium against corrosion phenomena.

Frequent maintenance. All XT winches should be washed frequently,
to avoid the accumulation of salt. Use plenty of fresh water and clean
it on all visible surfaces. Ensure the cleaning of the drainage channels
placed at the bottom of the winch, to avoid water stagnation.
Complete maintenance. With seasonal frequency XT winches should
be inspected visually inside.
Parts in need of maintenance. The most relevant parts are those
subject to movement and rubbing. These are the roller bearings, the
gears and pawls, the stem and the inside of the drum. For the complete
maintenance of the winch, disassemble the winch in order to access
the relevant parts.
TFL 400 Antal Grease. We recommend the use of Antal Grease, a
Teflon grease expecially made for lubrication of winches and protection
of aluminum parts in the marine environment (Mod. TFL400).
Cleaning. Remove old lubricant. In order to do so use a soft bristle
brush and solvent (use diesel in case you do not have other solvents).
Lubrication. It increases the performance and prolongs the life
of the winch. Also, it prevents the natural accumulation of salt to
obstruct the inner mechanism. Also, if you are using the TFL 400
Antal Grease, it also protects the aluminum parts from galvanic
corrosion, too.
Thus we advise to put a thin layer of TFL 400 Antal Grease; not only
to lubricate all moving parts, but also to protect the aluminum surfaces
in contact with s.steel parts, e.g. screws.
Kit Winch. Antal provides a repair kit winch containing pawls and
springs (Mod. Kit Winch).
Important Concepts
All detailed information about Maintenance are
contained in the Installation and Maintenance Manual
of the XT Winches. To download the manuals, go on
internet at the winch page, or digit www.antal.it
5. Maintenance of the Winch
The complete maintenance includes the opening of the winch,
the cleaning of the parts from old lubricants and the new lubrication
of all moving parts.
