ASSEMBLY

NOTE: 1. Letters in brackets refer to Fig.1

2. Unless otherwise stated, all nuts, bolts, washers and fixings are supplied.

IMPORTANT

For maximum safety and to ensure the adjustments are carried out correctly,

assistance should be employed during the assembly operation.

OPERATION

The Drum will turn immediately the machine is switched ON. Ensure therefore that nothing can
impede the drum before plugging into a 230 volt supply, and pressing the green ON button.

CAUTION: NEVER load the drum whilst it is stationary.

In order to rotate the drum, when stationary, pull the Hand Wheel outwards at the rim to
disengage the wheel from the Locking Plate (Fig.13). Turn the drum to the required position
then release the handwheel to lock it in that position.

1. The Stand

1.1 Attach the Leg Support to the Frame using
an M8 x 60 bolt - A, together with nut, spring
and flat washers provided,

Note: This bolt acts as a pivot pin...to be described
later.

1.2 Secure the leg using an M8x40 bolt - B
Screw on the nut, spring and flat washers
provided.

1.3 Turn the frame over and attach the Wheel
Axle in the same manner.

1.4 Slide a cup washer on to each stub axle,
followed by a wheel and a second washer.
Screw on the castellated nut and lock in
place with the split pin provided.

Tighten all nuts securely before righting the
stand.

2. The Bottom Drum

2.1 Carefully lower the bottom drum
assembly on to the stand as shown in
Fig.. 3, so that the bearing blocks slot
into the channels provided by the side
supports.

The drive shaft end, i.e. that end where
the pinion drives the drum, should be
at the AXLE end of the Frame.

2.2 Line up the holes in the side support
with those in the bearing block and
enter an M8x60 bolt with flat washer
and secure using a nut and spring
washer.

MAINTENANCE - General

Before each use

Inspect the machine to ensure it is not damaged and will perform its normal functions
correctly. If any damage is apparent, have it fixed before putting into service.

Periodically

Inject a few drops of light oil into the oil points, located on top of the Bearing Blocks and
rotate the drum to ensure distribution of oil within the bearing surface.

Inspect the paintwork and remove any rust that may be apparent before touching up
where necessary, with a rust resistant paint.

It is recommended that the Collar be removed, at least annually, and grease smeared on
the serrated underside of the lower rim. Ensure the collar is replaced correctly.

After each use.

It is strongly recommended that the machine is hosed down thoroughly with clean water, taking
care to prevent water from entering the electrical components during the cleaning process.
Turn the drum so that it is face down to allow all
water to drain off. Protect it from the elements
by covering with a tarpaulin. This is particularly
important if the machine is to be stored for a
period of time.

Storage

It is possible to fold the leg and axle assembly
beneath the frame by removing their upper
mounting bolts, and slackening off the lower
mounting bolts so that the leg, or axle assembly.
pivots beneath the frame, as illustrated.

ELECTRICAL CONNECTIONS

3. The Upper Drum

Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved
13 amp BS 1363 plug, or a suitably fused isolator switch.

WARNING! THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in the mains lead are coloured in accordance with the following

code:

Green & Yellow - Earth

Blue - Neutral

Brown - Live

As the colours of the flexible lead of this appliance may not correspond with the coloured
markings identifying terminals in your plug proceed as follows:

• Connect GREEN & YELLOW cord to terminal marked with a letter “E” or Earth symbol
“ ” or coloured GREEN or GREEN & YELLOW.

• Connect BROWN cord to terminal marked with a letter “L” or coloured RED.

• Connect BLUE cord to terminal marked with a letter “N” or coloured BLACK.

If this appliance is fitted with a plug which is moulded onto the electric cable (i.e. non­rewireable) please note:

1. The plug must be thrown away if it is cut from the electric cable. There is a danger of
electric shock if it is subsequently inserted into a socket outlet.

2. Never use the plug without the fuse cover fitted.

3. When replacing a detachable fuse carrier, ensure the correct replacement is used (as
indicated by marking or colour code).

4. Replacement fuse covers can be obtained from your local dealer or most electrical
stockists.

FUSE RATING

The fuse in the plug must be replaced with one of the same rating (13 amps) and this
replacement must be ASTA approved to BS1362.

We strongly recommend that this machine is connected to the mains supply via a Residual
Current Device (RCD)

If in any doubt, consult a qualified electrician. DO NOT attempt any repairs yourself.

Note:
Before bolting down the upper drum section, it is necessary to perform a ‘dry run’ in order to

determine the correct orientation, to ensure all components are correctly aligned.

3.1. Lower the upper drum section on to the lower drum.

Rotate it until the position is found where the mixing blade upper
mounting hole lines up with the corresponding hole in the upper
drum section, and the lower mounting hole becomes aligned
with the hole in the base of the lower drum section.

Mark this position on the upper and lower rims with a pencil or
chalk mark, then remove the upper drum section.

3.2. Apply a film of impact adhesive (not supplied) to the rim of the
drum, according to the manufacturers instructions, and ensuring
the rim is perfectly clean beforehand. Position the rubber seal
on to the rim so that the holes in the seal and those in the rim of
the drum are aligned.

3.3. With assistance, lower the Upper Drum section on to the Lower
Drum, so that the two marks, previously made, are aligned.

Insert M6 x 18 bolts into each of the holes in the rim together
with a flat washer, and secure from below with a spring washer
and nut, ensuring the tightening process is carried out progressively.

3.4. Secure the Mixing Blades to the Upper
Drum by inserting an M6x20mm screw with
a flat and leather washer, through the hole
in the drum and through the upper
mounting hole in the mixing blade.

Secure on the inside using a flat washer, spring
washer and nut. Do not tighten at this stage.

3.5 Secure the Mixing Blades to the lower drum
in a similar manner, ensuring the leather
washers are in place.

3.6 Finally,tighten both top and bottom Mixing
Blade mountings.

4. The Collar

4.1 Liberally grease the underside of the rim of
the drum.

4.2 Wrap the collar around the rim of the drum
and secure using the M6 bolts with flat and
spring washers provided. Ensure flat washers
are used at the bolthead and at the nut.

Tighten the clamping nuts - A before
tightening the locating bolts -B

IMPORTANT:
The Drum Collar is a Safety Feature, and must
ALWAYS be in place. NEVER operate the
machine with the collar removed.

5. The Hand Wheel & Fittings

Fig.6

6. The Motor Covers and Fittings

Fig.9

5.1 Slide the Locking Plate over the large
diameter shaft, at the leg end of the frame,
with the rim facing inwards, as shown in Fig.6.

Secure with two M8x25 bolts with nut, spring
and flat washers

5.2 Insert the spring, into its holder in the
Handwheel, and holding it in place as shown
in Fig.7, slide the wheel over the large diameter
shaft so that the shaft retains the spring.

NOTE:
This operation may need a little exertion in order

to compress the spring sufficient to be able to
slip the handwheel on to the shaft.

5.3 Line up the holes in the bracket on the
handwheel with the hole drilled in the shaft,
then insert the M10 x 65mm bolt with flat
washer at the bolt head.

NOTE:
You will find it an easier task to line up the holes

on one side of bracket only, to begin with. Enter
the bolt, then use that as a pivot, by pushing
the handwheel IN to square it up, in order to
line up the holes on the other side. When the
holes at the opposite side are aligned, tap the
bolt through GENTLY to avoid damaging the
threads.

5.4 Screw on two nuts. Screw the first nut up
against the bracket, but not so tightly so as
to prevent the handwheel from pivoting
about the bolt. Lock the nut in this position
by screwing up the second nut so that they
are tight against each other.

NOTE:
The handwheel must be allowed to pivot about

the bolt so that the lugs on the handwheel can
be engaged or disengaged from the slots in
the Locking Plate.

5.5 Finally, screw the handle into the handwheel
hub, tightly

6.1 Bolt the Inner Cover to the Bearing Block. Use
two M8 x 25mm bolts, with flat washers at the
bolt heads, (within the Inner Cover), and spring
washers with nuts to the rear of the Bearing
Block. Tighten the nuts.

6.2 Bolt on the Motor Support Plate as shown in
Figs. 9 and 10, by inserting two M6 x 50mm
bolts, with flat washers, through the holes in:

a. the Support Plate
b. the slotted holes in the Inner Cover
c. the spacer, (which is inserted between

the Inner Cover, and the Frame

d. the Clamping plate.

NOTE:
The securing plate is steel, whereas the spacer is plastic and is the thicker of the two plates.

Insert the first bolt and thread on the nut by one turn only, before inserting the 2nd bolt.

Fig.7

6.3 Thread on a spring washer and nut, but DO NOT tighten the nut at this stage

6.4 Slide the Pulley on to the shaft, having lined up the key and keyway. Ensure the grubscrew

in the hub of the pulley faces outwards. Push the pulley on to the shaft until the end of
the shaft is slightly proud of the central boss. This is not a critical measurement. Lock the
pulley in this position by tightening the grub screw.

6.5 Slip the drive belt over the pulley

6.6 If the Motor pulley is not fitted, slide it on to the

shaft fully and tighten the grub screw using a
hex. wrench.

6.7 Place the motor, (which has the Outer Cover

attached via the power cable), on the motor
support plate, and slip the drive belt over the
pulley. It may be necessary to manoeuvre the
Motor support upwards to achieve this.

NOTE: It is now most important that the motor
pulley be aligned so that it is directly in line with

Fig.8

o

the driven pulley. This is achieved as follows:

6.8 Bolt the Motor, square on the Support so that

the back edge of the motor mounts are 25mm
from the edge of the support (see Fig. 11).

6.9 Allow the motor and Support to drop as far as

possible under its own weight in order to tension
the drive belt. Tension is correct when there is
approximately 1/4" total deflection at the centre
of the belt run when using moderate thumb
pressure. Tighten the mounting bolts
progressively ensuring the support plate is
parallel to the ground.

6.10 Finally, attach the outer cover using the three

screws provided.
