or maximum safety and to ensure the adjustments are carried out correctly,
assistance should be employed during the assembly operation.
THE STAND
1. With the frame (P) lying on its
side, attach the axle assembly (E)
as shown in fig 2, using two M8 x
60 bolts, together with nut, spring
and flat washers.
2. Turn the frame over and attach
the front leg (L) as shown.
3. Stand the assembly upright and
slide a wheel on to each stub
axle, followed by a large flat
washer and secure them using
the split pins.
Fig. 2
THE LOWER DRUM
1. With the help of an assistant if
required, lower the lower drum
assembly (C), onto the side
supports of the stand as shown in
fig 3, so that the bearing blocks at
each end, slot into the channels
provided by the side supports.
• The larger diameter shaft should
be at the Leg end of the stand.
2. Use an M8 x 60 bolt with flat
washer at each fixing position,
and secure using a nut and spring
washer.
Fig 3
7
3. Slide the circular locking plate (D), over
the large diameter shaft, at the leg end of
the frame, with the rim facing inwards, as
shown in Fig.4. (Note that the centre hole
in the plate is cut away to allow the plate
to pass over the circlip on the shaft).
Secure with two M8 x 25 bolts, each with a
nut, flat washer and spring washer.
THE HANDWHEEL
1. Insert the spring into its holder in the centre
of the wheel spar. Hold it in place, and
slide the handwheel over the shaft so that
the shaft retains the spring, and the holes
in the bracket Y, (Fig 4), line up with the
drilled hole in the shaft.
2. Insert the M10 x 65mm bolt with flat
washer at the bolt head, and screw on
two nuts. Screw the first nut up against the bracket firmly, 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 tightly.
Fig. 4
NOTE: The handwheel must be allowed to pivot about the bolt so that
the lugs on the bracket (Y) can be engaged or disengaged from
the slots in the locking plate.
THE MIXING BLADES
1. Bolt the mixing blades in place loosely as
shown in Fig 5.
• Two holes are provided at the base of
the drum into which an M8 x 20 bolt may
be inserted from the inside the drum.
These bolts are supplied attached to the
blades and are provided with a flat and
leather washer. The leather washer
should contact the drum.
2. A spring washer and a nut should be
threaded on loosely onto the bolt from
the outside. Do not tighten these yet.
Fig. 5
THE UPPER DRUM
1. Position the rubber sealing ring on to the rim of the lower drum, ensuring
the holes in the seal and those of the drum line up.
2. Push an M6 x 16 cross headed screw through the rim from below and twist
through the corresponding hole in the sealing ring.
• The screws will hold the sealing ring loosely in position and not drop out.

3. With assistance if required, rest the upper drum so that it sits on the rim of
the lower drum. Rotate it so that the screws enter the fixing holes from
below. Look to see that the holes for the upper mountings of the mixing
blades also line up with those in the upper drum.
4. When all fixings are correctly lined up, use the screws, nuts and flat
washers to gently pull the upper and lower drum halves together, gripping
the seal between them. Look inside the drum to check that the seal is
sitting correctly in position.
NOTE: It is desirable practice for the screws to be fitted from above,
therefore, remove them one at a time and re-fit the correct way,
adding a spring washer at each position.
5. Finally, tighten all the fastenings progressively.
6. Secure the mixing blades to the upper drum by inserting the dome
headed coachbolt, through the hole in the drum from the outside,
ensuring the square portion of the bolt seats in the square hole in the
drum. The leather washer should bear against the drum.
7. Secure the mixing blade on the inside using a flat washer, spring washer
and nut.
8. Finally, ensure top and bottom mixing blade mountings are tight.
THE MOTOR COVER, MOTOR SUPPORT & DRIVE PULLEY
Note: To restrain it in transit, the
motor will be found bolted
to the inner cover with
suitable packing materials.
Remove the bolts which are
used for this.
1. Bolt the inner motor cover (S) to
the bearing block using two M8 x
25mm bolts with flat washers at
the bolt heads, from within the
inner cover, and spring washers
with nuts to the rear of the
bearing block. Leave the nuts
loose at this stage.
2. Attach the motor support plate
(F), as shown in Fig. 6, by inserting
four M6 x 65mm bolts, through
the holes in the support plate (F),
the slotted holes in the inner
cover (S), and the spacer, which
is inserted between the back of
the inner cover, and the frame
(see fig 6).
9
Fig. 6
The bolts extend through the securing plate which locates behind the
frame, each bolt being secured using a spring washer and nut. The nuts
should be left loose at this stage.
NOTE: The spacer and securing plate are of similar construction,
however, the LARGER of the two should be used as the SPACER.
3. When all four bolts are fitted, centralise the inner cover (S) on the support,
then fully tighten the two bolts securing it to the bearing block.
4. Remove any adhesive tape used to secure the key to the drive shaft
during transit and slide the drive pulley (Q) on to the shaft, having lined up
the key and keyway. Ensure the grub screw in the hub of the pulley faces
outwards (see Fig 7).
• If the fit is unduly tight, check that the hole in the pulley is smooth and
clear of any excess paint and clean up if necessary using a round file. It
may be necessary to drive the pulley on to the shaft using a soft faced
hammer, until the central boss is roughly flush with the end of the shaft.
Lock the pulley in this position by tightening the grub screw.
THE DRIVE BELT & MOTOR
1. Wrap the drive belt around the drive pulley, seating it into the groove.
2. Place the motor on the support plate with the motor pulley resting on the
drive belt. Fit four M8 x 25mm bolts through the slotted holes in the motor
mounting bracket and through those in the motor support plate, ensuring
flat washers are in place against the bolt head. Fit a flat washer, followed
by a spring washer and nut to each of the bolts from below, leaving the
nuts loose at this stage.
NOTE: During this operation, take care not to
strain the power cable which is
attached to the motor cover.
3. Slide the motor support plate (F) upwards
until the motor and support plate are sitting
level and secure in this position temporarily,
by nipping up two of the four nuts securing
the support plate to the frame, (do not fully
tighten them). The motor, belt and support
plate should be as shown in Fig 7.
4. Hold the steel guide rod so that it rests
across the face of the upper pulley as
shown in Fig 7, as near to the centre of the
pulley as possible. Gently adjust the position
of the motor and motor support plate until
the back of the motor pulley just comes into
contact with the rod.
5. Check the distance between the back of
the motor mounting bracket and the back
10
Fig. 7
edge of the motor support plate as
shown in fig 8, to ensure the motor is
square to the support and frame. Secure
Fig. 8
the motor in this position by fully
tightening the four mounting bolt/nuts.
• This adjustment ensures that the two
pulleys are in alignment and it is
important that time is taken to ensure it is
correct, otherwise premature failure of
the drive belt could occur.
6. Slacken the two nuts, previously nipped
up, which secure the motor mounting
plate to the frame, then push down on the motor so that tension is applied
to the belt. The tension is correct when there is approximately ½"
movement at the centre of the belt when using moderate thumb
pressure. When satisfied, secure the motor support plate by evenly
tightening the nuts behind the securing plate.
NOTE: It is important that the belt tension and pulley alignment are
correct, to ensure satisfactory operation of the machine and to
prevent excessive wear and premature failure of the drive belt.
7. To attach the outer cover to the inner cover it is first necessary to attach
the support chain, using the cross headed screws attached with washers
and nuts, to the holes provided in the inner and outer cover. The outer
cover is then secured to the inner cover using similar cross headed screws
with nuts and washers.
NOTE: The chain is a safety feature to prevent undue strain on the power
cable when the outer cover is removed, and it is important that it
is attached at all times.
DRUM COLLAR
NOTE: The drum collar is a safety feature, and must ALWAYS be in place.
DO NOT operate the machine with the collar removed.
1. Before the collar is attached, it is recommended that a layer of grease
(not supplied) is applied to the drive teeth under of the rim of the drum.
2. Attach the drum collar as shown in Fig 9. The two halves must bolted
together using three M6 x 20mm
bolts with a flat washer, spring
washer and nut, and each half is
secured to a bracket at either
side with a single M6 x 10mm
bolt with a flat and spring
washer. (Bolts may be supplied
already fitted to the collar).

CARE AND MAINTENANCE
STARTING WORK
Inspect the power cable and ensure it is completely free from damage and
is not in danger of being damaged by vehicles, equipment or other
operations taking place on the work site.
Important: Do not load the drum when the machine is switched off. Always
set the machine running before filling.
AFTER USE
It is essential that the machine is hosed down thoroughly with clean water,
being sure to remove all traces of cement mix especially from around the
mixing blades, Take care to prevent water from entering the motor housing
and if necessary, wrap a polythene sheet or bag over it during cleaning.
PERIODICALLY
It is recommended that the collar occasionally be removed and grease
smeared on the drive teeth underside of the lower rim. Ensure the collar is
replaced correctly.
After extensive use, inspect the paintwork and remove any rust that may be
apparent before touching up where necessary with a rust resistant paint.
It may be benificial to inject a few drops of light oil into the lubrication points
located on top of the bearing blocks and rotate the drum to ensure
distribution of oil around the bearing surface.
STORAGE
By removing the higher of the two
bolts connecting the legs to the frame,
the leg/axle assemblies can be
hinged, so as to collapse the machine
to low level as shown in Fig 10. The
lower bolts will need to be slackened
off for this.
The wheels can still be used for
mobility in this position. Always replace
the bolts loosely in their normal
positions during storage.
CAUTION; OWING TO THE WEIGHT OF THE MACHINE, TWO PEOPLE WILL
BE REQUIRED TO UNBOLT THE SUPPORTING COMPONENTS AND SAFELY
LOWER THE MIXER TO THIS POSITION.
