2 Safety
2.1 Personal safety
▶ Use the right tool for the job. Do not use the tool for purposes for which it was not intended. Use it only
as directed and when in technically faultless condition.
▶ Never tamper with or modify the tool in any way.
▶ Only persons who are familiar with it, who have been trained on how to use it safely and who understand
the resulting hazards are permitted to use the tool. The tool is not intended for use by children.
▶ Stay alert, watch what you are doing and use common sense when operating the tool. Do not use the
tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention
while operating the tool can result in serious personal injury.
▶ The user and persons in the vicinity must wear suitable protective goggles, a hard hat, ear defenders,
protective gloves, protective footwear and light respiratory protection while the tool is in use.
▶ Always hold the tool firmly with both hands on the grips provided. Keep the grips dry, clean and free
from oil and grease.
▶ Never use the tool without the guard (hood). Adjust the guard to the correct position. The guard must be
securely attached and positioned for maximum safety, so that the smallest possible part of the cutting
disc is exposed to the operator. Make sure that sparks created during use do not present a hazard. The
guard helps to protect the operator from broken disc fragments, inadvertent contact with the cutting disc
and uncontrolled flying sparks.
▶ Do not touch rotating parts – risk of injury!
▶ Maintain a firm footing and balance at all times. This will allow you to control the tool better, even in
unexpected situations. Avoid unusual postures.
▶ Wear suitable work clothes. Do not wear jewelry or loose clothing. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry or long hair can be snagged by moving parts.
▶ If the tool or the cutting disc has been dropped or has fallen, check the tool and the cutting disc for
damage. Change the cutting disc if necessary.
▶ Switch the tool off before adjusting the guard or changing the cutting disc.
▶ Wear protective gloves also when changing the cutting disc. Touching the cutting disc presents a risk of
injury (cuts or burns).
▶ Wear eye protection. Flying fragments present a risk of injury to the body and eyes.
▶ 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
Printed: 24.04.2018 | Doc-Nr: PUB / 5265931 / 000 / 02

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 whether parts 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.
▶ Fit the filled water tank only after the saw has been mounted on the saw trolley. This will help to prevent
the trolley falling over.
▶ Do not stand the product and the saw trolley on an inclined surface. Always check to ensure that the
product and the saw trolley are standing securely.
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.
2.5 Cutting work using cutting discs
▶ Use only cutting discs with a rated maximum permissible speed that’s at least as high as the highest
spindle speed.
▶ Check that the outside diameter and the thickness of the cutting disc comply with the capacity rating of
the product.
▶ Never use cutting discs that are damaged, run untrue or vibrate.

▶ Do not use damaged diamond cutting discs (cracks in the steel disc, broken or polished segments,
damaged arbor hole, bent or distorted steel disc, heavy discoloration due to overheating, steel disc worn
away beneath the segments, diamond segments with no lateral overhang, etc.).
▶ Do not use toothed accessory cutting tools (e.g. toothed saw blades).
▶ When fitting the cutting disc, always take care to ensure that the disc’s specified direction of rotation
corresponds to the direction of rotation of the spindle.
▶ The cutting disc and flange or any other accessory must fit the arbor of the product exactly. Cutting
discs or accessories with arbor holes that do not match the mounting hardware of the product will run
out of balance, vibrate excessively and may cause loss of control.
▶ Always use an undamaged clamping flange of the correct diameter which fits the cutting disc used.
The correctly fitting clamping flange supports the cutting disc and thus reduces the possibility of disc
breakage.
▶ Guide the product smoothly and do not apply lateral pressure to the cutting disc. Always bring the cutting
disc into contact with the workpiece at right angles. Don’t attempt to alter the line of cut by applying
lateral pressure or by bending the cutting disc while cutting is in progress.
▶ Wear protective gloves when changing the cutting disc as the disc will get hot during use.
▶ Abrasive cutting discs which are used for wet cutting must be used up the same day as long periods of
exposure to moisture have a negative effect on the strength of the disc.
▶ Observe the expiry date for resin-bonded cutting discs and don’t use the discs after this date.
2.6 Transport and storage
▶ Switch the product off before transporting it.
▶ Remove the cutting disc from the product after use. The cutting disc may suffer damage during transport
with the disc fitted.
▶ Handle the cutting disc carefully and store it in accordance with the manufacturer’s instructions.
▶ Always store and transport the product in an upright position, not lying on its side.
▶ Do not carry the saw trolley and the product together. Remove the water tank before transporting the
saw trolley.
▶ Do not lift the product and the saw trolley by crane. This is not permissible.
▶ Store the product in a secure place when not in use. Products which are not in use must be stored in a
dry, high place or locked away out of reach of children.
▶ When laying the product down, make sure that it stands securely.
▶ After use, allow the product to cool down before packing it away or placing a cover over it.
▶ Store gasoline and oil in a well-ventilated room in fuel containers that comply with regulations.
