RODIA SAFETY
●
KEEPING THE WORK AREA CLEAN.
It is important that the working area be
clean so as to avoid potential accidents or
injuries.
●
DO NOT USE THE EQUIPMENT IN
DANGEROUS ENVIRONMENTS.
It is important that power tools not be used
in wet environments. The equipment
should never be used in the rain. Also, it is
advisable to keep the working area well lit.
●
CHILDREN SHOULD BE KEPT AWAY
FROM THE WORKING AREA.
Only the operator of the equipment should
be in the working area. All other people
especially children should be kept away at
a safe distance.
●
KEEP THE WORKING AREA CHILDPROOF.
It is important to keep the working area
child proof. This can be done by using
locks on the equipment, plastic plugs for
the electrical outlets and possibly even
master switches on the equipment.
●
CLOTHING.
It is important that the operator does not
wear loose clothing that can potentially get
caught in moving parts of the equipment.
It is recommended to wear non-slip shoes
along with a hair covering to keep hair
away from the moving parts.
●
SAFETY GLASSES AND HEARING
PROTECTION.
It is important to wear safety
glasses and hearing protection
when operating any type of
equipment. Be sure that the
safety glasses you wear are
impact resistant.
●
SECURE WORK
Clamps or a vise should be used to hold
your work whenever practical. Keeping
your hands free to operate the machine is
safer.
●
PROPER FOOTING
It is important to keep proper footing and
balance at all times when operating equip-
ment. If proper footing is not observed by
doing such things as overreaching, serious
injury may occur.

RODIA SAFETY
The use of this machine generates dust. Excessive airborne particles may cause irritation to eyes, skin
and the respiratory tract. To avoid breathing impairment, always us dust controls and protection suitable
to the material being mixed.
Comply with American National Standards Institute Safety Code, B7.1 and, Occupational Safety and
Health Act covering speed, Safety Guards, Flanges, Mounting Procedures, General Operating Rules,
Handling, Storage and General Machine Conditions.
CALIFORNIA PROPOSITION 65 MESSAGE:
Some dust created by power sanding, sawing, grinding and other construction activities contain chemi-
cals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
●
Lead, from lead-based paints
●
Crystalline silica, from bricks and cement and other masonry products
●
Arsenic and chromium, from chemically treated lumber
For Further information, consult the following sources:
http://www.osha-slc.gov/sltc/sillicarystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.html
Your risk from these exposures varies depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment,
such as dust masks that are specially designed to filter out microscopic particles.

OPERATING INSTRUCTIONS
PAGE 10 RODIA ANGLE GRINDER OPERATING MANUAL V01/2007R1
BEFORE USE
Take the machine out of the box and
check for any possible damage that
may have occurred during shipment.
Never use damaged equipment or
blades.
Turn off and unplug the machine before mounting
or replacing the cutting blade. Never use a cutting
blade with a lower RPM than that of your angle
grinder (See specifications).
MOUNTING OF THE CUTTING
BLADE
1) Turn the machine over with the spindle
facing upward and mount the flange.
Rotate the flange until you feel it locking.
2) Mount the cutting blade.
3) Screw the wheel nut onto the spindle by
hand
4) Lock the spindle and tighten the wheel
nut using the spanner
5) To remove the cutting blade follow these
procedures in reverse order.
CUTTING PROCEDURES
It is important that during the cutting
of the tile you don’t force the Cutting
Blade. Let the weight of the machine
do the cutting. Just slowly move the
machine through the cutting guide.
Forcing the tool will result in poor cutting
performance and chipping of tiles. It
could also damage the Cutting Blade
and the Machine.
Use of the supplied
Watertank
for wet cutting
●Fill the Watertank to the maximum
quantity as indicated on the tank and
pressurize by pumping at least 10
times.
●Connect the water hose to the Angle
Cutter.
●Open the tap until a little bit of water
is spraying on the Cutting Blade.

REPAIR & MAINTENANCE
Always unplug the machine before attempting
any maintenance.
1. Inspection of screws
Periodically inspect the screws for safer
operation. Tighten loose screws firmly
to prevent hazardous situations.
2. Inspection of carbon
brushes
Worn carbon brushes may cause motor failure.
Replacement of the carbon brushes is recommen-
ded when the brushs have reached their wear
limit. Always keep the brush holders clean so that
the brushes can move freely.
Use original spare parts only and have the
machine serviced at authorized Service Centers.
Non original parts may lead to damage to the
machine or hazardous situations.
3. Motor
The rotor and stator in the motor are the core of
the machine. Do not scratch the surface of the
windings in the motor, and never apply oil or
water on it.
4. Keep ventilation
slots clean
Ventilation slots should be kept open and clean at
all times. Clogged slots prevent proper cooling of
the motor and will lead to damages.
Penetration of dust into the motor will lead to
machine failure. The motor should be cleaned after
every 50 hrs of operation by blowing compressed
air through the ventilation slots while the machine
is running at no load speed.
5. Storage
Store the machine in a dry place and out of reach
of children.
6. Failure and repair
Do not attempt to repair the machine yourself, this
may lead to unrepairable damages or injuries.
Repair and maintenance should be performed by
qualified personell only.
