Should you require insert tools not included in the stan-
dard programme, please contact the Hilti customer ser-
vice department or your Hilti sales representative. Hilti
offers a comprehensive range of special insert tools in
professional quality.
Check your insert tools at regular intervals and
replace them in good time. A damaged or badly worn
connection end may result in damage to the power tool.
Please observe the instructions on care and mainte-
nance of your insert tools given in the following section.
Take care to ensure that saw blades are always
stowed away in their own compartment in the toolbox.
Damage to the supply cord caused by the sharp teeth
of the saw blades can thus be avoided.
The Hilti Corporation accepts no liability for damage of
this kind or any resulting consequential damage.
Care and maintenance
Care of the tool
The outer casing of the tool is made from impact-resis-
tant plastic. Grip sections, the dust shield and the sup-
ply cord protective sleeve are made from an elastomer
material.
Clean the outside of the tool at regular inter-
vals using a slightly damp cloth. Don’t use a spray, steam
pressure cleaning equipment or running water for clean-
ing. This may negatively affect the electrical safety of the
tool. Always keep the grip surfaces of the tool free from
oil and grease. Don’t use cleaning agents which contain
silicone.
Never operate the tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Don’t permit foreign objects to enter the
interior of the tool.
Clean off dirt and dust deposits and protect your insert
tools from corrosion by wiping them from time to time
with an oil-soaked rag. Always keep the connection end
clean and lightly greased.
Maintenance
Regularly check all external parts of the tool for
damage and check that all controls operate faultlessly.
Don’t operate the tool when parts are damaged or when
the controls do not function faultlessly. Have your tool
repaired by a Hilti service center.
Repairs to the electrical sections of the tool may be car-
ried out only by trained electrical specialists.
Orbital action
Orbital action Orbital action
off on
The cutting performance under certain conditions, e.g.
when cutting wood materials or thin sheet steel, can be
increased through use of the orbital action. The orbital
action is switched off or on by moving the function selec-
tion switch ẋ to the corresponding end position. The
switch may be operated while the motor is running or
when it has stopped.
Adjusting the contact shoe
Unplug the supply cord from the mains socket in
order to prevent unintentional starting.
Adjustment of the shoe does not require the use of tools
and is thus quick and convenient Ẍ. Correct adjustment
of the contact shoe ensures that the full length of the
saw blade can be used optimally and may also improve
access in corners.
Plunge sawing
The plunge sawing technique should be used only on
soft materials and when the orbital action is switched
off. A little practise is required in order to be able to
plunge the blade into the material while the saw is run-
ning and thus make cut-outs without first drilling a hole.
Plunge sawing is possible only with short saw blades.
Plunge cuts may be started with the saw in one of two
different positions: in the normal position ẗẻ or in the
reversed position ẗẻ.
Hold the saw with the front edge of the contact shoe
against the workpiece and switch on. Press the saw firm-
ly against the workpiece and begin the plunge move-
ment by reducing the angle of the saw (contact shoe)
to the workpiece.
When the blade has passed through the workpiece, bring
the saw into the normal working position (the entire sur-
face of the shoe in contact) and then continue sawing
along the line.
Blades and accessories

Hilti power tools have been designed to work opti-
mally as a system together with Hilti insert tools.
Accordingly, highest performance and longest life
expectancy can be achieved when you use this pow-
