Hilti NURON DSH 600-22 Original Operating Instructions page 13

▶ Dust produced by grinding, sanding, cutting and drilling can contain dangerous chemicals. Some
examples are: lead or lead-based paints; brick, concrete and other masonry products, natural stone
and other products containing silicates; certain types of wood, such as oak, beech and chemically
treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶ working in an area that is well ventilated,
▶ avoidance of prolonged contact with dust,
▶ directing dust away from the face and body,
▶ wearing protective clothing and washing exposed areas of the skin with water and soap.
▶ Risk of injury by falling tools and/or accessories. Before starting work, check that the battery and installed
accessories are secure.
Electrical safety
▶ Before beginning work, check the working area (e.g. using a detector) to ensure that no concealed
electric cables or gas and water pipes are present. External metal parts of the power tool can become
live, for example if you accidentally damage electric wiring.
▶ Always clean the power tool and the Li-ion batteries separately; do not use a high-pressure cleaner and
do not attempt to spray them clean with a garden hose, for example.
▶ Always dry cut-off saw and Li-ion battery separately from each other if they are wetted.
Using and handling the power tool
▶ Always hold the power tool securely with both hands firmly on the defined grips.
▶ Do not touch rotating parts; rotating accessory tools in particular can lead to injuries if touched.
▶ Do not switch the power tool on until you are at the workplace and are holding the power tool firmly with
both hands.
▶ Before use, check that the accessory tool has been installed correctly and is secure, then run the power
tool under no load for one minute in safe conditions. Switch off the power tool immediately if significant
vibration occurs or some other fault is perceived. Under these circumstances, check the entire system
to ascertain the cause.
▶ Do not use the power tool if it starts sharply or jerkily. The electronics might be defective. Have the
power tool repaired by Hilti Service.
▶ Do not, under any circumstances, use the power tool without the guard correctly installed.
▶ Always adjust the guard to the optimum position to protect yourself from sparks and flying fragments of
material.
▶ Make sure that the water supply does not exceed the maximum permissible pressure of 6 bar.
▶ When it is hot, do not set down the power tool near flammable liquids or surfaces.
Slits cut in load-bearing walls of buildings or other structures may influence the statics of the structure,
especially when steel reinforcing bars or load-bearing components are cut through.
▶ Consult the responsible structural engineer, architect or person in charge of the building project before
beginning the work.
▶ Guide the power tool carefully and make straight cuts in order to keep the accessory tool from jamming.
Do not attempt to make curved cuts.
▶ Guide the power tool smoothly, without applying lateral pressure to the accessory tool. Always bring
the power tool into contact with the workpiece at right angles. Do not attempt to change the line of cut
by applying lateral pressure or by bending the accessory tool while cutting is in progress. This could
damage the accessory tool and cause it to break.
▶ Never use the power tool without the spray guard.
DSH 700-22
Safety for applications with saw trolley
▶ Do not carry the saw trolley and the product together.
▶ Fit the filled water tank only after the saw has been mounted on the saw trolley. This precaution
enables you to keep the saw trolley from tipping over.
▶ Remove the filled water tank before transporting the saw trolley or removing the cut-off saw from the
saw trolley.
▶ Do not stand the product and the saw trolley on an inclined surface. Apply the wheel brake when you
leave the power tool with saw trolley standing.
▶ If the throttle cable of the saw trolley sticks, immediately remove the batteries from the power tool.
