7.5 Plunge cutting 14
WARNING
Apply the appropriate safety measures at the rear of
the workpiece when plunge sawing. Only use suitable
saw blades, which are as short as possible.
Use the plunge cutting technique only on soft materials.
It takes a little practice to start the cut, without previously
drilling a starting hole, by plunging the blade into the
surface while the power tool is running. This is possible
only with short saw blades. For plunge cutting, the power
tool may be used either in the normal position or in the
reversed position.
1. Bring the forward edge of the contact shoe into
contact with the surface of the material to be cut.
2. Press the transport lock and then press the control
switch.
3. Press the forward edge of the contact shoe against
the surface and begin the plunge action by slowly
increasing the angle of attack. To prevent stalling, it
is important that the power tool is running before the
saw blade is brought into contact with the surface.
4. Once the saw blade has penetrated right through
the material, bring the power tool into the normal
working position (contact shoe flush with the workpiece) and then continue sawing along the cutting
line.

8 Care and maintenance
en
CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional starting.
8.1 Care and maintenance
Keep the blades clean, especially their connection ends,
in order to ensure trouble-free operation of the blade
holder.
Keep the blade holder clean.
The power tool has been adequately lubricated during
assembly. After a long period of heavy use it is recommended that the power tool is inspected by Hilti. This
will help to extend the life of the power tool and avoid
unnecessary repair costs.
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use cleaning agents which contain silicone.
The outer casing of the power tool is made from impactresistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool.
8.3 Care of the Li-ion battery
Avoid entrance of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging
the battery as soon as a significant drop in performance
is noticed.
NOTE
If use of the power tool continues, further battery discharge will be stopped automatically before the battery
cells suffer damage.
Charge the battery with the Hilti charger approved for use
with Li-ion batteries.
NOTE
- A conditioning charge (as is required with NiCd or
NiMH batteries) is not necessary.
- Interruption of the charging procedure has no negative
effect on battery life.
- Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as
with NiCd or NiMH batteries).
- For best results, batteries should be stored fully
charged in a cool dry place. Avoid charging the battery
in places subject to high ambient temperatures (e.g. at
a window) as this has an adverse effect on battery life
and increases the rate of self-discharge.
- If the battery no longer reaches full charge, it may
have lost capacity due to aging or overstressing. It
is possible to continue working with a battery in this
condition but it should be replaced in good time.
8.4 Maintenance
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the power tool if parts are
damaged or when the controls do not function faultlessly.
If necessary, the power tool should be repaired by Hilti
Service.
8.5 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.

10 Disposal
CAUTION
Improper disposal of the equipment may have serious consequences: the burning of plastic components generates
toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to very high
temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit
unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and
pollution of the environment.
CAUTION
Dispose of defective batteries without delay. Keep them out of reach of children. Do not attempt to open or dismantle
batteries and do not dispose of them by incineration.
CAUTION
Dispose of the batteries in accordance with national regulations or return them to Hilti.
Most of the materials from which Hilti power tools or appliances are manufactured can be recycled. The materials
must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for
taking back your old power tools or appliances for recycling. Please ask your Hilti customer service department or
Hilti representative for further information.
