is designed for use with this power tool. Observe national regulations applicable to the materials
you intend to work with.
Electrical safety
▶ Before beginning work, check the working area (e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present. External metal parts of the power tool
may become live, for example, when an electric cable is damaged accidentally. This presents a serious
risk of 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.
▶ Have dirtied or dusty power tools that are used frequently for working on conductive materials
checked at regular intervals by a Hilti Service Center. Dust, especially dust from conductive materials,
or dampness on the surface of the power tool can, under unfavorable conditions, lead to electric shock.
▶ Switch the power tool off and unplug the supply cord in the event of a power failure or interruption
in the electric supply. This will prevent accidental restarting when the electric power returns.
Special safety instructions for jig saws.
▶ Always guide the product away from your body when cutting.
▶ Never position your hands ahead of or on the saw blade.
▶ Never cut into unknown materials and keep the line of cut above and below the workpiece free of
obstacles. The product can kick back if the saw blade comes into contact with an obstructing object.
▶ Switch the product off for transport.
▶ Never operate the product without the contact guard correctly installed. Do not touch rotating
parts. Switch the machine on only after it is in position at the workpiece. Touching rotating parts,
especially rotating accessory tools, may lead to injury.
▶ Before beginning the work, check the hazard classification of the dust that will be produced. Use
an industrial vacuum cleaner with an officially approved protection classification in compliance
with locally applicable dust protection regulations.
▶ If the work involves breaking right through, take the appropriate safety measures on the opposite
side. There is a risk of injury when the drill bit breaks through the object in which the hole is being drilled.
▶ Never reach or grip below the workpiece while cutting.
Safety instructions for the WSJ-DRS dust removal module
▶ When changing the filter, hold the product and/or the WSJ-DRS in a position in which the dust container
can be removed by being pulled vertically down. This prevents dust from escaping.
▶ Use light respiratory protection when changing the filter.
