SAFETY WARNINGS & INSTRUCTIONS

UNDERSTANDYOUR MIXER

Read and understand the owner’s manual and labels afﬁxed to the

mixer. Learn its application and limitations as well as the speciﬁc

potential hazards peculiar to it. Become familiar with the controls

before operating this mixer.

STAY ALERT

Do not operate the mixer while under the inﬂuence of drugs, alcohol,

or any medication that could affect your ability to use it properly. Do

not use this mixer when you are tired or distracted from the job at

hand. Watch what you are doing at all times. Use common sense.

AVOID DANGEROUS CONDITIONS

Make sure there is adequate surrounding workspace. Keep your

work area clean and well lit. Cluttered areas invite injuries. Keep

area around the mixer clear of obstructions, grease, oil, trash and

other debris which could cause persons fall onto moving parts.

Only use or operate the mixer on solid, ﬂat, level ground that is ca-

pable to support the weight of the mixer and its load to prevent the

mixer from tipping over. Do not attempt to move the mixer when it

is loaded and/or in operation.

This mixer is intended for the production of concrete, mortar and

plaster. It is not suitable for the mixing of ﬂammable or explosive

substances. Do not use it in areas where fumes from paint, solvents

or ﬂammable liquids pose a potential hazard.

INSPECTYOUR MIXER

Check your mixer before turning it on. Keep guards in place and

in working order. Do not plug mixer with motor cover off. Check

all bolts, nuts, and screws for tightness before each use, especial-

ly those securing guards and drive mechanisms. Vibration during

mixing may cause these to loosen. Form a habit of checking to see

that all the adjusting tools, shovels, hand trowels and other tools/

equipments are removed from mixer area before turning it on. Re-

place damaged, missing or failed parts before using it. Warning la-

bels carry important information. Replace any missing or damaged

warning labels.

DRESS PROPERLY

Do not wear loose clothing, gloves, neckties or jewelry (rings, wrist

watches).They can be caught in moving parts. Protective electrical-

ly nonconductive gloves and nonskid footwear are recommended

when working. Wear protective hair covering to contain long hair,

preventing it from getting caught in machinery. Wear a face or dust

mask if the operation is dusty. Always wear safety goggles and/or

face shields. Everyday eyeglasses have only impact resistant lens-

es.They are not safety glasses.

2620-176

DO NOT ABUSE CORD

Never carry mixer by cord or yank it to disconnect it from socket.

Keep cord from heat, oil and sharp edges.

EXTENSION CORDS

Extension cords must be no longer than 50 m/164' in length. The

wire section must be 1.5mm2/ 3/64"2on 120V to allow sufﬁcient 2

current ﬂow to the motor. Improper use of extension cords may

cause inefﬁcient operation of the mixer which can result in over-

heating and motor damage. Only extension cords to H07RN-F spec-

iﬁcation intended for outdoor purpose may be used. Avoid use of

free and inadequately insulated connections. Connections must be

made with protected material suitable for outdoor use. Make sure

that any extension cord connections are dry and safe. Ensure that

the extension cord is carefully laid out avoiding liquids, sharp edg-

es and places where vehicles might run over it. Avoid allowing the

extension cord to be trapped underneath the mixer. Unroll it fully or

it will overheat and could catch ﬁre.

AVOID ELECTRICAL SHOCK

Check that the electric circuit is adequately protected and that it cor-

responds with the power, voltage and frequency of the motor. Do

not plug or unplug the motor while standing in or around damp or

wet ground. Do not use the mixer in wet or damp areas or expose

it to rain. Prevent body contact with grounded surfaces: pipes, radi-

ators, ranges, and refrigerator enclosures. Make sure your ﬁngers

do not touch the plug’s metal prongs when plugging or unplugging

the mixer.

KEEP VISITORS AND CHILDREN AWAY

Keep unauthorized persons away from the mixer. Do not allow chil-

dren to handle or climb on or in the mixer.

DO NOT OVERREACH

Keep proper footing and balance at all times when loading or un-

loading the mixer. Never stand on mixer. Serious injury could oc-

cur if the mixer is tipped or if the moving parts are unintentionally

contacted. Do not store anything above or near the mixer where

anyone might stand on the mixer to reach them.

AVOID INJURY FROM UNEXPECTED ACCIDENT

Keep hands out of the way of all moving parts. Do not place any

part of your body or any tool, like shovel in the drum during oper-

ation. When operating, do not pass hands through the clearance

between frame and support arm or the one between the drum and

support arm.

DON'T FORCE TOOL

It will do a better and safer job at its design rate. Always work within

the rated capacity. Do not start the motor if the drum is fully loaded.

ASSEMBLY INSTRUCTIONS

It is recommended that two people assist in the assembly.

THE STAND

1. With a split pin inserted into the in-

ner holes in each stub axle, place a

ﬂat washer, then a wheel followed

by another ﬂat washer. Insert an-

other split pin into the axle holes

outside each ﬂat washer. Bend

each side of the pins outward so

they do not fall out.

M8 70

2. With the frame lying on its side, at-

tach the support leg as shown. In-

sert two M8X70 hex bolts through

the holes from one side, then ﬂat

washers, lock washers and nuts

from the other side.

3. Turn the frame over and attach the

axle bracket with wheels in the

same manner.

4. Make sure all bolts and nuts are

tightened.

2620-176

THE BOTTOM DRUM

THE MIXING BLADES

THE UPPER DRUM

1. Slide the bearing block on the

shaft. Hold it in place with Ø 42

spiral ring.

2. Carefully, and with two people,

set the bottom drum with support

arm onto the side supports of the

stand as shown, so that the bear-

ing blocks slot into the channels

provided by the side supports. The

larger diameter shaft should be at

the leg end of the stand.

3. At each side, line up the holes in

the side support with those in the

bearing block and insert a M8X65

hex bolt from one side, then a

ﬂat washer, lock washer and nut

from the other side. Tighten with

a wrench.

Mount the mixing blades inside the bot-

tom 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.

NOTE: Two arrows are labeled on upper

drum and bottom drum to make their

position relative. If you have any difﬁ-

culty 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.

1. Position the upper drum on bottom

drum over the rim, making sure the

mounting holes align in both as

well as the labeled arrows.

2. Insert a M8X20 cross headed screw

into each mounting hole in the rim.

Secure each bolt from below with

a ﬂat washer, lock washer and nut.

Make sure the tightening prOcess is

carried out progressively.

3. Secure the mixing blades to the

upper drum by inserting two

M8X20 cross headed screws, from

the outside through the holes in

the drum.

4. A leather washer should be posi-

tioned inside between the drum

and blade. Secure the mixing

blade on the inside using a ﬂat

washer, spring washer and nut.

5. Finally, ensure top and bottom

mixing blade mountings are tight.

1. Slide the locking plate over the

large diameter shaft at the leg end

of the frame with the rim facing in-

wards as shown. Secure with two

M8X25 bolts, each with a nut, lock

and ﬂat washers.

2. Insert the spring into the bar pipe.

Holding it in place with a ﬁnger,

place the bar over the larger diam-

eter shaft so that the shaft retains

the spring. Press down on bar

until the holes in the bracket line

up with the hole drilled. Insert a

M10X65 hex bolt and screw on a

nut with ﬂat washers from the oth-

er side. Screw the nut up against

the bracket ﬁrmly, but not so tight-

ly so as to prevent the bar from

pivoting about the bolt.
