▶ Use clamps or some other suitable means to firmly secure the workpiece to a stable supporting
surface. Holding the workpiece only by hand or against your body leaves it unstable, which can lead to
loss of control.

Additional safety instructions for saws
Personal safety
▶ Keep your hands away from the cutting area and the blade. Keep your second hand on the front gripping
area or the motor housing. When both hands are on the saw they cannot be injured by the saw while it is
in use.
▶ Use the product only when it is in perfect working order.
▶ Never tamper with or modify the power tool in any way.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Before starting work, check the hazard class of the dust that will be produced when working. Use
an industrial vacuum cleaner with an officially approved protection class in compliance with the locally
applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of
wood and concrete/masonry/stone containing quartz, minerals or metal can be harmful to health.
▶ Make sure that the workplace is well ventilated and, if necessary, wear a respirator appropriate for
the type of dust generated. Contact with or inhalation of the dust can cause allergic reactions and/or
respiratory or other diseases among operators or bystanders. Only specialists are permitted to handle
material containing asbestos.
▶ Do not reach underneath the workpiece.
▶ Always hold the power tool firmly with both hands on the handles provided for the purpose and position
your arms to absorb kickback forces.
▶ Keep the grips clean and dry.
▶ Position yourself off to one side of the blade, never bring the blade into line with your body. The saw can
jump backward toward you if kickback occurs.
▶ If the saw blade binds or when you interrupt work for any reason, switch off the saw and hold it motionless
in the material until the saw blade comes to a complete stop. Never attempt to remove the saw from the
workpiece or pull the saw back while the blade is in motion, as otherwise the saw could kick back.
▶ When restarting a saw in the workpiece, center the saw blade in the kerf and check that saw teeth are
not in engagement with the workpiece.
▶ Use extra caution when sawing into walls or other blind areas. As it enters the material the blade might
encounter a hidden obstruction, resulting in kickback.
▶ Before starting the saw, hold it so that it cannot be triggered and grip and pull the saw blade to check
that it is securely engaged in the chuck. A saw blade flung out by the saw is extremely dangerous.
Electrical safety
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool can become live, presenting a risk of electric shock, if you
accidentally damage an electric cable.
▶ Hold the power tool by the insulated gripping surfaces when performing work in which the accessory
tool might come into contact with concealed wiring. If the accessory tool comes into contact with a live
wire, metal parts of the power tool can also become live, resulting in an electric shock.
▶ Check the machine's supply cord at regular intervals and have it replaced by a qualified specialist if
found to be damaged. If the machine's supply cord is damaged it must be replaced with a specially
prepared and approved supply cord available from Hilti Customer Service. Check extension cords at
regular intervals and replace them if found to be damaged. Do not touch the supply cord or extension
cord if it is damaged while working. Disconnect the supply cord plug from the power outlet. Damaged
supply cords or extension cords present a risk of electric shock.
Power tool use and care
▶ Do not use dull or damaged blades. These cause increased friction and present a high risk of the saw
blade binding or kicking back.
▶ Comply with the manufacturer's instructions for handling and storing saw blades.
▶ The product must be pressed against the workpiece until the contact shoe makes firm contact. This
ensures optimum and safe progress as you work.
▶ Wear suitable protective clothing as protection against hot particles of material.
