NOTE:

THE UPPER DRUM

THE TIPPING WHEEL

Mount the mixing blades inside the bottom drum

loosely as shown - Two holes are provided at

the base of the drum into which a M8X20 bolt

may be inserted from the outside. A leather

washer, flat washer, lock washer and a nut

should be threaded on loosely on the inside.

The leather washer should be placed under the

blade down against the drum.

Two arrows are labeled on upper

drum and bottom drum to make

their position relation. If you have

any difficulty in correctly

positioning the mixing blades, it is

helpful if you temporarily mount

the upper drum on the top of the

bottom drum, rotating it so that the

two arrows line up.

Position the upper drum on bottom drum

over the rim, making sure the mounting holes

align in both as well as the labeled arrows.

Secure the mixing blades to the upper drum

by inserting two M8X20 cross headed screws,

from the outside through the holes in the

drum.

A leather washer should be positioned inside

between the drum and blade. Secure the

mixing blade on the inside using a flat washer,

spring washer and nut.

Slide the locking plate over the large diameter

shaft at the leg end of the frame with the rim

facing inwards as shown. Secure with two

M8X25 bolts, each with a nut, lock and flat

washers.

Finally, ensure top and bottom mixing blade

mountings are tight.

2. Screw a M8X16 hex bolt with spring and flat

washers into each threaded hole in the

rim/ring gear. Make sure the tightening

process is carried out progressively.

THE TRANSMISSION CASE

The wheel must be allowed to pivot

about the bolt so that the lugs on

the bracket can be engaged or

disengaged from the slots in the

locking plate.

NOTE:

Lining up the keyways, slide the transmission

case over the pinion shaft. Secure the case to

the frame with four M8 nuts and flat washers.

OPERATION INSTRUCTIONS

The spring-loaded tipping wheel with locking

lugs provides an easy positive control of the

drum which can be locked in the mix, discharge

and stored position.

DRUM TILTING

Insert the spring with the washer on the top

into the sleeve on the tipping wheel. Slide

the wheel over the larger diameter shaft until

the holes in the braket line up with the hole

drilled. Insert a M10X65 hex bolt with a flat

washer and screw on a nut with a flat washer

from the other side. Screw the nut up against

the bracket firmly, but not so tightly so as to

prevent the wheel from pivoting about the

bolt. Tighten the M10X30 socket head cap

screw on the sleeve to adjust the spring

tension.

M10 65

The drum is locked in position by lugs on the

self-locating tipping wheel which engage into

the locking plate on the mixer frame. To tilt the

drum, withdrawn the tipping wheel to dis-engage

the locking lugs. This then allows the tipping

wheel and drum to be turned in the same

direction.

To retain the drum in position, aligning the lugs

with the slots, release the tipping wheel a little

while retaining the drum. Rotate the tipping

wheel until the locking lugs engage into the

locking plate on the mixer frame.

Loading/Mixing Position

For Mortar For Concrete

Emptying Position Storage Position

Completely unwind the extension

cord. Connect it to the concrete

mixer first before plugging in power

supply.

Always start the mixer before

loading the drum. Loading the drum

with drum rotating.

Do not throw material into the

mixer to avoid sticking firmly to

the back of the drum. Trickle it

steadily over the ram.

For best results, proceed as follows:

1. Add the required amount of gravel into the

drum.

Add the required amount of cement into the

drum.

Add the required amount of sand into the

drum.

Pour the required amount of water into the

drum.

EMPTYING

Do not turn mixer off while full of

load. Emptying the drum with drum

rotating.

CLEANING

Never put hands inside the drum

with drum rotating.

Thoroughly clean the mixer at the end of each

day’s operation. Keep your mixer clean. The

slightest trace of material left in the drum will

harden and attract more each time you use it

until the machine is useless. Dried cement should

be scraped out of the drum. Do not throw bricks

into mixer drum to clean it out. Do not beat on

the drum with a shovel, a hammer or other tools

to break up accumulations of dried cement mix,

as damage to the mixer may result. The drum

may be scoured for approximate 2 minutes,

using 1” gravel and water mixture. Then

discharge the gravel/water mixture and hose

down the drum assembly inside and out. The

IP45D or IP44D protection class construction

of the concrete mixer enables you to hose down

the drum assembly safely.

A built-in thermal protecter is

arranged in the motor to prevent it

from overheating. The thermal

protecter restores automatically

when the motor cools down.
