wood may split on the narrow side. Mount the lifting winch and the swivel servo for actuating the fire
cannon (133), and attach the bottom sleeve (153) to the mounting plate using a 2.2 Ø x 9.5 mm self-
tapping screw. You will need to pull off the water hose beforehand, otherwise it will obstruct the
screwdriver.
Don’t forget to place a 6.0 / 3.2 Ø washer (163) between mounting plate and bottom sleeve. Attach
the cable guide return bar (165) to the mounting plate using thick cyano, as shown in the drawing.
The next step is the most important part of assembling the lift mechanism: installing and adjusting the
winch cord (160).
Starting from the two-pulley winch drum, the winch cord runs from drum A (pulley A) to the return
block (156), and from there back again to drum B (pulley B). Set the winch to the “fire cannon
retracted” end-point, and wind sufficient cord onto drum A by hand - around 5 full turns. The principle
is that the system unwinds the same length of cord as it winds onto drum B. To compensate for
fluctuations in winch drum diameter caused by the thickness of the cord as it is wound up or unwound,
the tension spring (159) must be incorporated into the winch cord. The tension on the spring should
be no more than moderate. There is a 1 mm Ø hole in the sliding sleeve (154); fit the split pin (124)
through this from the underside, and form a second loop in it at the top. Engage the tension spring
(159) in the lower loop, then connect the winch cord to the upper loop.
The top face of the winch casing features a screw potentiometer which you can rotate to adjust the
number of drum revolutions within the range 1.5 to 5.5 turns. If an inner drum diameter of 25 mm is
used, the cord travel range is about 12 to 45 cm. For the Parat a travel of about 26 - 27 cm is
required. Another method of adjusting the travel is to use the servo travel adjustment facility (or Dual
Rates, or end-point adjustment) if you have a computer transmitter.
Important note
: it is essential to ensure that the winch is not mechanically obstructed at any point in
its full winding travel, including trim. If this is not the case the winch or the cord guidance system may
be damaged. We recommend that you drill a 2 mm Ø hole in both pulleys A and B; thread both ends
of the cord through the holes and tie knots to secure them.
Fit an M3 x 3 grubscrew in the base (1) of the fire cannon. This makes it possible to remove the fire
cannon if required, in order to dismantle the lift mechanism (see drawing).
The first step is to remove the winch drum and wind five turns of cord onto the inner pulley; wind it on
clockwise, and leave about 10 cm of cord free. Wind one turn anti-clockwise onto the outer pulley B,
leaving about 90 cm of cord free. Move the winch to one end-point and check the direction of rotation,
then fit the drum on the winch again, and run both cords over the return bar (165) and through the slot
in the bottom sleeve. Connect the short free end of the cord to the tension spring, and connect the
spring to the bottom loop (124) on the sliding sleeve (154). Run the long end of the cord over the
return block (156) and attach it to the top loop (124).
We recommend that the winch should be assigned its own channel, operated by a proportional slider
module, Order No. 4152, as this enables you to adjust the cord travel and direction of rotation without
difficulty.
The cover (161) is a vacuum-moulding, and should be trimmed as shown in the drawing. At the top it
is held in place by the water tube (151). At the bottom it should be secured to the bottom sleeve (153)
using double-sided adhesive tape
This cover is very important
, as it prevents the water hose coiling
up or becoming kinked in the mast or funnel when the fire cannon is retracted; the hose should simply
retract into the hull in the space between the two drive batteries.

The hawser guide (168) and the tyres (169) are vacuum-moulded items, each of them
assembled from two half-shells. Assemble the parts, paint them, then attach them to the model
in the position shown in the drawing.
35.
The anchor winch (176), anchor stopper (177), coupling winch (178), towing winch (179) and
towing hook (180) take the form of sets of ready-made parts which should be assembled as
described in the instructions supplied with them. Paint these assemblies and mount them on the
model.
Painting
General notes
•
If you wish to apply the final painted finish by brush you will only achieve good results if you use
high-quality modelling paints. Your local model shop will advise you, but we strongly recommend
Graupner paints, as they have been tested on a wide range of surfaces.
•
Whichever type of paint you select, use only ONE type, i.e. all paints of the same type and made
by the same manufacturer, otherwise you may encounter compatibility problems, with one coat
dissolving another or causing bubbling. Be particularly careful when combining spray cans and
brushing paints; always carry out a test on some scrap plastic to check that the materials don’t
react with each other.
