SAFETY PRECAUTIONS
The saw blade should be inspected daily for excessive wear, core cracks, and
arbor damage. Replace the blade if it shows any signs of damage.
• To mount the blade; clean the arbor and outer fl ange, then tighten the nut
to secure the blade.
• Keep limbs and fi ngers clear from the blade when it is in use.
• To reduce risk of electrical shock, it is recommended to use a Ground Fault
Circuit Interrupter (GFCI) switch
• Always have a qualifi ed technician service the machine.
We recommend that you use the following Personal Protective Equipment
(PPE) when operating the machine:
WEAR HEARING PROTECTION
WEAR EYE PROTECTION
WEAR A DUST MASK
USE A BLADE GUARD WHEN OPERATING THE SAW

GENERAL SAFETY RULES
• Never misuse the machine or work in an unsafe manner.
• Always wear the correct PPE when operating the machine. (See Page1)
• Always remain alert when the machine is in use. Operating the machine
while distracted may lead to serious injury.
• Before you start working, do a basic risk assessment of your environment.
• Take measures to ensure that the machine is in a safe and trouble-free
condition prior to usage. Use the machine only when all protective devices
(i.e. guards, noise absorbers, emergency shut-off devices) are located and
operating as intended.
• A visual check of the machine must be made at least once a shift to ensure
that visible damages or faults are recognized. Any changes (including
changes in the performance or behavior of the machine) must be reported
to the supervisor. If required, cut off the power and correct any faults
before using the machine.
• In the case of a malfunction, stop the machine immediately, then follow
the operating instruction steps and look for any damages or faults.
• Be sure to connect the plug to a properly grounded socket, and that there
is no damage to the cable to reduce the risk of electric shock.
HEALTH WARNINGS
Dust is created when sawing, which could contain harmful particles.
Some examples of these particles include:
• Lead from lead based paints,
• Crystalline silica from bricks, concrete, and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk to these types of exposure varies depending on how often you do
this type of work and your environment.
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 fi lter out microscopic particles.

UNPACK & INSPECTION
After opening the container, carefully lift the saw frame handles and place it on
a fl at, level working area. Be certain that you have the following items before
you discard the container:
• Saw: 1 piece
• Saw frame support: 4 pieces
• Water pump: 1 piece
• Hex Wrench No. 4,6,8: 1 piece/each
• Adjustable Wrench: 1 piece
• Wrench: 1 piece
The Masonry Saw is shipped completely assembled and ready for use
excluding the diamond blade. Inspect the saw for shipping damage. If any
damage is found, contact the shipper immediately and fi le a freight claim.

MANUAL
Pg.4
ASSEMBLY & OPERATION
• After opening the package and confi rming everything has been included,
install the 4 removable legs underneath masonry saw frame by tightening
knobs.
• Plug the rubber block into the drain hole. Please inspect the motor and
wires before powering up the saw.
• DO NOT connect the plug into the power socket before installing blade.
• Keep the blade shaft clean and dry, remove the blade safety guard, install
the blade on the blade shaft, tighten the collar.
• Fill the water pan with clean water and fully submerge the water pump.
• Connect power to the pump and be sure there is enough water fl ow to the
blade before cutting.
• Keep the input hole of water pump clear, check regularly to avoid slurry
block.
• Rotate the blade manually (slowly) to check the blade condition, make
sure it’s rolling smoothly and is properly mounted.
• Always ensure you are using the correct rated voltage.
• Keep the motor rotating in no-load condition for one minute before cutting
in order to check related parts. Listen to the sound of the machine in
operation for abnormal behavior.
• DO NOT use if there is anything wrong or unusual.
• Check pump operation to ensure enough water is fl owing during operation.
• Put the cutting head in the desired position: either for sawing at right
angles or for mitering (90° or 45°). Loosen the bolt slightly by using the
ring wrench then tilt the head into the desired position. Tighten the bolt.
The exact position 90° or 45° can be adjusted by means of the adjustment
bolts.
• When nearing completion of the cut, pull back the cut, and slightly hold
back the conveyor cart. Always keep the blade out of the cutting slot
before turning off the motor.
• Place the cutting material on the conveyor cart, clamp and hold it fi rmly
against the backstop. Align the cutting material line with the blade cut line.
• The motor will stop in an overload condition. This means the overheat
protection device is working as intended.
• Turn off power and unplug the machine after each use. Empty the water
tank, remove dust, debris and slurry from machine. Keep the equipment
clean and dry.

WORKING INSTRUCTIONS
• Please study this operating manual carefully and ensure you follow the
safety guidelines before using the BCA350 Masonry Saw.
• Professional training for workers is necessary.
• Always check work area for hidden wires, water or gas pipes before
working.
• Sawing action requires the use of water, since the use of electrical
equipment in wet areas is hazardous, the equipment must be grounded.
Always wear insulated footwear and gloves for extra protection against
shock hazards.
• Always wear safety goggles or glasses with side shields.
• Avoid vibrating or bumping the saw during cutting to insure equipment and
blade lifespan is not reduced.
• Keep any electrical equipment, the motor and cables away from water.
• Keep the blade free from any material when you start the saw.
• DO NOT operate without water. Suffi cient water fl ow is required to cool
blade and remove slurry.
• DO NOT remove the safety guard while the machine is in operation.
• DO NOT use the machine when you are tired, distracted or under the
infl uence of drugs, alcohol and any medication causing decreased
awareness or control.
