the important items, individuals should look for and obey Caution,

Warning and Danger signs placed on equipment, and displayed in

the workplace. Operators should read and follow safety instructions

packed with each product.

Learn how each machine works. Even if you have previously used

similar machines, carefully check out each machine before you use

it. Get the “feel” of it and know its capabilities, limitations, potential

hazards, how it operates, and how it stops.

FLEXTOOL OPERATING INSTRUCTIONS FLEXTOOL PLANETARY CONCRETE GRINDER FCG-450

CRYSTALLINE SILICA AND SILICOSIS

Concrete grinding can expose the operator and bystanders to ne

concrete dust particles including crystalline silica that is generated

in workplace processes such as crushing, cutting, drilling, grinding,

sawing or polishing of stone, concrete and other man-made

products that contain silica. Exposure to crystalline silica can

be extremely harmful to your health and cause a wide range of

respiratory illnesses.

Flextool recommends that all operators of equipment used in the

above listed activities familiarise themselves with the “Working with

silica and silica containing products” safety handbook available on

the Safe Work Australia.

website: www.safeworkaustralia.gov.au

MECHANICAL HAZARDS

• DO NOT operate the machine unless all protective guards in place.

• KEEP hands and feet clear of rotating and moving parts as they

will cause injury if contacted.

• ENSURE both the machine and the operator are stable by setting

up on a level surface. Make sure the machine does not tip over,

slide or fall while in operation or unattended.

• DO NOT leave the machine in operation while it is unattended.

• EXERCISE CARE when operating the unit. Extended exposure

to vibration or repetitive work actions may be harmful to hands

and arms.

• NEVER stand on the unit while it is operating.

• ONLY USE the recommended grinding plate or shoes. Allow the

machine to cool before servicing or replacing parts, severe burns

may be caused by coming in contact with hot discs or segments.

• ENSURE that repairs to the motor and machine are carried out by

qualied personnel.

ELECTRICAL HAZARDS

• RISK OF FATAL OR SERIOUS INJURY FROM ELECTRICAL

SHOCK may arise through incorrect use, operating the equipment

where leads and other electrical components are damaged or

through ingress of moisture and water.

• ENSURE that the grinder is disconnected from electric power

source and motor operation switch is in the OFF position before

removing guards, making adjustments or repairs or changing

grinding consumables.

• ENSURE that the area requiring grinding does not contain any

“live” electrical cables, gas, water or communication services

which may be damaged by the action of the unit.

• INSPECT electrical leads, plugs and sockets regularly for damage,

if any damage is found, isolate equipment and seek immediate

repair.

• ENSURE if the grinder is used in a wet / damp environment that a

residual current device (RCD) safety switch is used to reduce the

risk of electric shock.

• ENSURE if an extension cord is used, it is suitable for outdoor use

and in good working condition. Never connect multiple extension

cords and limit the extension cord length to 20 metre. Do not

operate the equipment using coiled or tangled extension leads.

• BEFORE USE check the condition of all cables, the motor

starter box, and power lead / plug to ensure it is in good working

condition. If there are any signs of deterioration and / or damage,

do not use the grinder.

• DO NOT adjust any settings within the motor starter box as they

have been set to ensure the correct operation of the grinder.

• ENSURE that repairs to electrical components are carried out by a

QUALIFIED and LICENCED electrician.

NOISE HAZARDS

• EXCESSIVE NOISE can lead to temporary or permanent loss of

hearing.

• WEAR approved hearing protection as required by Occupational

Health and Safety regulations while operating the machine to limit

noise exposure.

PERSONAL PROTECTIVE EQUIPMENT

• WEAR eye protection and dust mask when working in a dusty

environment.

OPERATION

The Flextool Planetary Concrete Grinder FCG-450 operates from

a standard 240 volt / 10 amp power outlet. Prior to connecting the

unit to the power socket, ensure there is a clear and safe working

environment that is free from hazards, and complete the following

checks.

It is important to ensure the grinder is set up correctly to ensure safe

operation. Ensure the grinder is tted with the appropriate grinding

shoes for the application and that they are tted securely to avoid

dislodgement during operation. To do this, place both the grinding

head weights and the handle into the 12 o’clock position and tilt the

machine all the way back. The handlebar should now be resting on

the ground and the grinding heads exposed.

Ensure the grinder is switched o or unplugged before changing or

tting shoes.

FLEXTOOL OPERATING INSTRUCTIONS FLEXTOOL PLANETARY CONCRETE GRINDER FCG-450

Fit the required grinding shoes into position using the tapered easy

lock mechanism, to lock them into position you may need to give

them a gentle tap with a small hammer. (Do not hit them to hard or

you may damage the grinding segment) For correct tment of the

polishing resins ensure the adaptor plate is used and that the velcro

pad is clean and provides a strong hold of the resin pad, ensure the

adaptor plate is seated into the grinding head and has a strong hold

with the magnetic retainers.

Now that the necessary grinding shoes or resins have been tted,

the handlebar can now be lifted and the grinding head can carefully

be lowered onto the ground. Always ensure a rm grip and a

balanced wide stance when lowering the grinder and never drop the

grinding head, this can cause damage and lead to costly repairs.

Concrete grinders must always be used in conjunction with a

suitable dust collector equipped with H-Class ltration for the safe

extraction and capture of concrete dust. This is done by connecting

the hose of the dust collector unit to the 50 mm dust outlet situated

at the rear of the grinder beneath the main electrical inverter box.

It is also important to ensure the rubber shroud is in contact with

the ground to ensure all grinding dust is captured, this is done by

pushing downward on the oating rubber shroud.

Move the handlebar into the operating position and adjust the hand

grips to the desired height for optimal control and comfort specic to

the operator’s height.

The operation of the concrete grinder is managed via the control

panel situated at the top of the handlebar. This panel is equipped

with a Start and Stop button as well as a speed controller dial which

adjusts the grinding head speed, this function can be particularly

useful when removing coatings and in combination with PCD

grinding shoes.

CARE AND PREVENTIVE MAINTENANCE

• CAUTION: Prior to undertaking any maintenance ensure the

unit is switched o at the power outlet and the power lead is

disconnected form the wall outlet.

• ALWAYS use personal safety equipment while undertaking repairs

to the grinding head that could expose the user to ne concrete

dust particles – always wear a dust mask.

• Inspect the grinding plates and shoes before each use for damage.

• Check all fasteners for tightness as the machine is subject to

vibration.

• Clean the underside of the unit regularly to prevent a build-up of

material.

CLEANING AND STORAGE

• ENSURE to switch o the machine and remove plug from outlet

prior to cleaning and servicing.

• AVOID cleaning the machine with a high-pressure cleaner, this can

damage lters and electronics.

• Wear proper personal protective equipment while cleaning the

machine.
