INSTRUCTIONS
1. Mark out the parts from the plan (Page 7) on to the PVC plastic section (1)
Drill the 13mm hole diameter for the cab window and the holes for the
axles (4mm diameter ) and the trailer coupling (3mm diameter ) before
any sawing any of the other parts. Prior to drilling the 13mm diameter hole
drill a 4mm pilot hole. The hole in the underneath of part (a) should be
countersunk . Any sawn parts should be cut out with a fretsaw and the saw
cuts cleaned up with a le ..Shape the axle carrier as shown in the plans and
round the corners o . You can leave this rounding o if you wish as is does
not aect the outcome of the project.
Please Note
When sawing it is important to ensure that the straight cuts are always as ac-
curate as possible. Use soft jaws when holding your the work in a vice . Mark
out any holes to be drilled with a scriber or pointed tool to make sure that
there is an indentation and the drill bit does not slip .
Drill the holes all
the way through!

2. Mark out the positions of the two axle hol-
ders (d) and (e) on part (a) Finally glue the
two axles holders (d & e) on the underneath
of the cab (a ) with a plastic glue and leave it
to set

3 Mark out the grey prole strip (2) according to the plan
(Page 7) . Drill the two 3mm holes, then the two 6mm
diameter. holes all the way through. Remove any extra
material with a fretsaw or le so that a rectangular slot
shaped hole is made (12 x 6mm ) Finally mark out and
saw the parts (g-i) and le the saw cuts smooth
4. Take the two yellow Light Emitting Diodes ( LEDs ) and
insert them in the holes part (g) . Here you must ensure
that the at part of the LED ( Cathode ) faces downward
. Glue them in position
Note :The Cathode ( short leg ) of the LED faces down-
wards . Part ( g is inserted in the base of part (a) it may
need to be shaped so that it ts correctly. It can then be
nally glued in place and left to dry

5. Saw the 200mm threaded rod (3) into 55mm sections as shown in the plan .Clean up the saw cuts with a workshop le .
6. Insert a countersunk head machine screw ( 4 ) from under-
neath through the 3mm hole and wind on 3 nuts ( 5) from
above then contra tighten them in position . Finally add a
washer ( 7) . Then insert a threaded rod (J) through each of
the axle holders ( d+ g )

7. Thread a wheel (14) on the end of each axle so that they
are all equally arranged and will rotate easily !

8. Glue the battery pack holder ( c ) on the underneath of the trailer (b) as shown , using a plastic or instant glue Then glue the
axle holder ( f) in position alongside the battery holder ,again use a plastic or instant glue and leave it to set

9. Insert both of red Light Emitting Diodes ( LEDs ) (13) in the holes in part ( h) and glue them in place. Here it is important that
the cathode leg ( The leg on the at side of the LED faces downwards.)
Note: The cathode leg is the shorter leg of the LED) and must be facing downwards ! Finally glue part ( h) in position as a
bumper to the underneath of the trailer (b) The slide switch (11) is mounted in the prole strip (i) and then glued in place as
shown with a plastic glue. Glue the mounted switch in squarely in place on the to surface of the trailer (b) as shown in the
plan and leave it to set

Instructions
10. Insert the threaded rod (3) as an axle into the axle carrier
(f). Add wheels (15) to both sides of the axle (j) as de-
scribed in step 7.
Drill a ø4mm hole
11. Drill a ø4mm hole through the centre of part (i) in order
to feed the cables through.
Cabling:
Wiring diagram:
12. Solder the resistor (12) to the outer switch connec-
tor (11). Strip the insulation from the red battery
clip cable (10), tin it, feed it upwards through the
drill hole in part (h) and solder it to the centre
switch connector (11). Strip the insulation from the
black battery clip cable, tin it and feed it upwards
through the drill hole in part (h). Solder the anodes
(long leg) of the red LEDs together. Then solder the
two cathodes (short leg) together. Do the same
with the two yellow LEDs. Cut o approx. 180mm
wire (red, 8) strip the insulation from both sides
and tin. Feed one end upwards through the drill
hole in part (h). Connect the other end to the two
anodes from the red LEDs (13). Cut o approx.
150mm wire (red, 8) strip the insulation from both
sides and tin. Again feed one end through the drill
hole, twist it with the end of the 180mm wire and
solder to the resistor (12). Connect the other end to
the anodes of the yellow LEDs (14).
Cut o approx. 180mm of black wire (9) strip the
insulation and tin. Feed one end upwards through
the drill hole in part (h) and twist it with the end of
the black cable from the battery clip (10). Solder
the other end to the two cathodes from the red
LED (13). Cut o approx. 150mm of black wire (9),
strip the insulation, tin, feed upwards through the
drilled hole, twist s well with the black cable from
the battery clip (10) and solder the three black cab-
les together. Connect the other end to the catho-
des from the yellow LEDs (14). Connect the battery
to the battery clip and insert the battery into its
compartment (part c).
Note: Do not touch any PVC parts with the solde-
ring iron when soldering!
