Safety instructions for assembly

WARNING: Read the following warning instructions carefully before using the
product.

WARNING: Never use a cutting blade for any other materials than what it was
intended to cut.

WARNING: Never use a diamond blade to cut plastic material. The heat produced
during cutting may melt the plastic and it can stick to the cutting blade and cause a kickback.

WARNING: Diamond blades become very hot when used. An overheated blade is a
result of improper use, and may cause deformation of the blade, resulting in
damage and injuries.

WARNING: A cutting blade may burst and cause injury to the operator.

WARNING: The cutting blade manufacturer issues warnings and recommendations for
the use and proper care of the cutting blade. Those warnings come with the cutting blade. Read and follow all instructions from the cutting blade manufacturer.

WARNING: A cutting blade should be checked before it is assembled on the saw
and frequently during use. Look for cracks, lost segments (diamond blades) or pieces broken off. Do not use a damaged cutting blade.

WARNING: Test the integrity of each new cutting blade by running it at full throttle for about 1 minute.

WARNING: Never use a cutting blade with a lower speed rating than that of the power
cutter. Only use cutting blades intended for handheld high speed power cutters.

WARNING: Do not use abrasive blades with water. The strength is impaired when
abrasive blades are exposed to water or moisture, which results in an increased risk of the blade breaking.

WARNING: Use only blades which are in compliance with national or regional
standards/regulations, for example EN 13236 or EN 12413 or ANSI B7.1.

WARNING: Cutting metal generates sparks that may cause fire. Do not use the machine
near ignitable substances or gases.

WARNING: Cutting metal is not allowed with the Vac attachment.

WARNING: Never use toothed blades such as wood cutting blades, circular toothed
blades, carbide tipped blades, etc. The risk of kickback is significantly increased and tips can be torn off and thrown at high speed.
Carelessness can result in serious personal injury or even death.

WARNING: Government regulation requires a different type of guarding for carbide
tipped blades not available on power cutters – a 360 degree guard. Power Cutters (this saw) use Abrasive or Diamond blades and have a different guarding system which does not provide protection against the dangers presented by wood cutting blades.

Note: Cutting with abrasive discs is not allowed with the Vac attachment. Use of abrasive discs causes unnatural wear on the Vac attachment.

Safety instructions for operation

Work area safety

WARNING: The safety distance for the power cutter is 15 meters (50 foot). You are
responsible to ensure that animals and onlookers are not within the working area.
Do not start cutting until the working area is clear and you are standing firmly.

• Keep work area clean and well lit.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
• Keep children and bystanders away while operating a power tool.
• Observe your surroundings to ensure that nothing can affect your control of the product.
• Ensure that no persons or objects can come into contact with the cutting equipment or be hit by parts
thrown by the blade.
• Do not use the product in bad weather, such asdense fog, heavy rain, strong wind, intense cold, etc.
Working in bad weather is tiring and can lead to dangerous conditions, such as slippery surfaces.
• Never start to work with the product before the working area is clear and you have a firm foothold.
Look out for any obstacles with unexpected movement.
• Ensure when cutting that no material can become loose and fall, causing injury to the operator. Take great care when working on sloping ground.
• Ensure that the working area is sufficiently illuminated to create a safe working environment.
• Make sure that no pipes or electrical cables are routed in the working area or in the material to be cut.
• If cutting into a container (drum, pipe, or other container) you must first make sure it does not contain flammable or other volatile material.

Electrical safety

WARNING: The machine (Great Britain 110V) is not equipped with a ground fault
circuit interrupter. The machine must always be used with an isolating transformer for protection in case an electrical fault should occur.

WARNING: Do not wash the machine with water, as water can enter the electrical
system or the engine and cause damage to the machine or short circuit.

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce the risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose the power tool to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• Check that the cord and extension cord are intact and in good condition. Never use the machine if the cord is damaged, hand it in to an authorized service
workshop for repair.
• To avoid overheating do not use the extension cord while it is rolled up.
• When using an extension cable, use only certified extension cables with sufficient reach. For more information, see Technical data on page 23 section.
An undersized cable means a risk of reduced machine capacity and overheating.
• The machine should be connected to an earthed outlet socket. Check that the mains voltage corresponds with that stated on the rating plate on the machine.
• Ensure the cord is behind you when you start to use the machine so that the cord will not be damaged

Personal safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use safety equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
• Avoid accidental starting. Ensure that the switch is in the OFF-position before plugging in.
• Prevent unintentional starting. Ensure the switch is in the OFF-position before connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have the switch on, can result in accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in
personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Dust collection can
reduce dust-related hazards.
• Remain at a distance from the blades when the engine is running.
• Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin color or condition. These symptoms normally appear in the fingers, hands or wrists. These
symptoms may be increased in cold temperatures.
