Use and Care Manual

4 English
▶ Make sure fire extinguishers are available for use as there is a risk of fire due to flying sparks and the use
of flammable fuel.
▶ Do not use reducing sleeves.
▶ Use of the wet cutting method is preferable in order to reduce the amount of dust produced when cutting
mineral materials and asphalt.
▶ Avoid skin contact with the slurry created when using the wet cutting method.
▶ Dust from materials such as paint containing lead, some types of wood, minerals and metal can be
harmful to health. Contact with or inhalation of the dust can cause allergic reactions and/or respiratory or
other diseases to the operator or bystanders. To reduce the amount of dust produced when cutting, we
recommend use of the wet cutting method. Make sure that the workplace is well ventilated. It is advisable
to wear a filter class P2 dust mask. Comply with national regulations applicable to the materials you will
be working with.
▶ Cutting material containing asbestos is not permissible.
▶ Take breaks between working and do relaxation and finger exercises to improve the blood circulation in
your fingers. Exposure to vibration during long periods of work can lead to disorders of the blood vessels
and nervous system in the fingers, hands and wrists.
▶ Consult the responsible structural engineer, architect or person in charge of the building project before
starting work. Slits cut into load-bearing walls or other structures can influence the statics of the structure,
especially when reinforcing bars or load-bearing components are cut.
▶ If the work involves breaking through, always secure the area on the side opposite to where the work is
being carried out. Pieces of debris could drop out and/or fall down and injure other persons.
▶ Never leave the tool running while unattended. Switch the engine off and wait until the cutting disc has
come to a complete standstill before placing the tool on the ground or before transporting it.
▶ Make sure that the pump cover is installed if you operate the tool without an external water pump.
▶ Switch the tool off after use.
▶ Maintain the tool carefully. Check for parts that are broken or damaged to the extent that the tool is not
in full working order. Have damaged parts repaired before using the tool.
▶ To avoid risk of injury, use only genuine Hilti accessories and accessory tools.
▶ Have the tool repaired only by qualified specialists using only genuine Hilti spare parts. The safety of the
tool can thus be maintained.
▶ Comply with national health and safety requirements.
2.2 Electrical safety
▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the machine may give you an electric shock if you damage an electric cable
accidentally.
2.3 Safety at the workplace
▶ Ensure that the workplace is well lit.
▶ Don’t work in closed rooms. Carbon monoxide, unburned hydrocarbons and benzene in the exhaust gas
may cause asphyxiation.
▶ Keep the workplace tidy. Objects which could cause injury should be removed from the working area.
Untidiness at the workplace can lead to accidents.
▶ Hot exhaust gases containing sparks or sparks generated by the cutting operation may cause fire or
explosion. Take care to ensure that the sparks generated do not ignite flammable (gasoline, dry grass,
etc.) or explosive (gas, etc.) substances.
▶ Before fitting the water pump, check to ensure that the maximum permitted water supply pressure of 6
bar is not exceeded.
2.4 Liquids (gasoline and oil) and vapors
▶ Allow the product to cool before refueling.
▶ Never smoke while refueling.
▶ Don’t refuel the product at the workplace area. When refueling, take care to avoid fuel spillage. Use a
suitable funnel.
▶ Avoid inhaling gasoline vapors and exhaust fumes. Take care to ensure adequate ventilation.
▶ Don’t use the gasoline or other flammable liquids for cleaning.
