this user manual before using the product,
including safety warnings, and any
assembly and operating instructions.
Keep the manual for future reference.
Safety precautions and recommendations
detailed here must be fully understood
and followed to reduce the risk of injury,
fire, explosion, electrical hazard, and/or
property damage.
Safety information presented here is
generic in nature – some advice may not
be applicable to every product. The term
"equipment" refers to the product, be it
electrical mains powered, battery powered
or combustion engine powered.
• Before Use - If you are not familiar with
the safe operation/handling of the
equipment, or are in any way unsure of
any aspect of suitability or correct use
for your application, you should
complete training conducted by a
person or organization qualified in safe
use and operation of this equipment,
including fuel/electrical handling and
safety.
• Do NOT operate the equipment in
flammable or explosive environments,
such as in the presence of flammable
liquids, gases or dust. The equipment
may create sparks or heat that may
ignite flammable substances.
• Keep clear of moving parts.
• Equipment may be a potential source of
electric shock or injury if misused.
• Do NOT operate the equipment if it is
damaged, malfunctioning or is in an
excessively worn state.

Equipment Safety
Concrete saws are high-speed, fast-cutting equipment with exposed blades that can cause
serious or fatal injury if not used correctly or without taking proper safety precautions. It is
extremely important that you read and fully understand the information in this section and all other
safety warnings / recommendations and usage instructions before using the equipment.
Operator
• If you are untrained in the use of a concrete saw, it is highly recommended that you be trained/instructed
by a suitably qualified or experienced person before using the machine.
• NEVER operate the machine when tired, or under the influence of any substance (medication, alcohol,
drugs etc) that may impair your judgement, alertness, physical strength, vision or dexterity.
• Maintain sure-footing and balance always when using or handling the machine and have full awareness
of your surroundings and any possible hazards.
• Prolonged use may lead to health complications, such as carpal tunnel syndrome, due to vibration. To
help reduce the possibility of such conditions, wear gloves, take breaks frequently, keep fingers and
hands warm, and maintain the equipment for optimal operation and minimal vibration. It is recommended
to seek medical advice if you feel numbness or burning sensations in fingers/hands.
Clothing and Protective Equipment – All Operators and Assistants
• Wear approved safety goggles, or safety glasses with adequate top and side protection. In addition to
eye protection, wearing a full-face shield is highly recommended.
• Wear suitable hearing protection.
• Wear approved respiration equipment.
• Wear heavy-duty, non-slip leather or protective gloves.
• Wear approved heavy-duty safety boots, with steel toe-caps and non-slip soles.
• Wear suitable overalls or work clothing that fits snugly, but does not restrict movement. Avoid loose
fitting clothing, scarves, jewellery etc and keep long hair contained to avoid getting caught or pulled by
the machine etc.
Work Area Safety
• Use EXTREME CAUTION to avoid underground power lines – contact can be fatal. Contact the
necessary utilities authority etc to ensure that it is safe to use the machine.
• The abrasive cutting action of the machine can generate dust and vapours which may contain harmful
chemicals. Know the nature of the material being cut before cutting and ALWAYS use appropriate dust
mask or respirator equipment.
• Ensure that any person other than the operator and any assistants is kept a minimum 10m (30') away
from where the equipment is being used.
• Be aware of fire risks resulting from machine use. Ensure that the machine exhaust and spark arrestor (if
equipped) is well maintained and that engine is tuned correctly.
• Refuel outdoors only. Avoid fuel spillage. Start the machine at least 3m (10') away from the fuelling
location.
Operational Safety
• Do NOT use the machine if the throttle or any safety guard or mechanism is not installed or is not
operating correctly – have the machine inspected and repaired at an authorised service centre before
using it again.
• Fully understand how to safely operate the machine and the sawing process to avoid "kick-back". See
Operation.
• Always hold the machine firmly with both hands during operation. Always use the machine handles.
