CAUTION
Do not lift the power tool away from the workpiece
until it has stopped completely.
CAUTION
Lay the power tool down only when it has come to a
complete stop.
CAUTION
The saw blade gets hot during intensive use.
Wear pro-
tective gloves.
Contact with the saw blade presents a
risk of burning injury.
8.1 Safe operation
7 8 9
DANGER
The power tool must be pressed against the work-
piece until the AVR contact shoe makes firm contact.
This helps ensure maximum safety and good perfor-
mance.
DANGER
Always use saw blades that project beyond the work-
piece over the entire length of the blade stroke.
This
will help to avoid violent kickback.
WARNING
Always hold the power tool securely with both hands
on the grips provided. Never use the power tool with-
out a fully functional hand guard.
The blade holder
presents a risk of injury.
8.2 Switching on
1. Disengage the transport lock.
2. Press the control switch.
8.3 Switching off
1. Release the control switch.
2. Engage the transport lock.
8.4 Plunge cutting
10
CAUTION
Apply the appropriate safety measures at the rear of
the workpiece when plunge sawing. Use only suitable
saw blades (length 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 AVR contact shoe into
contact with the surface of the material to be cut.
2. Disengage the transport lock.
3. Press the control switch.
4. 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.
5. Once the saw blade has penetrated right through
the material, bring the power tool into the normal
working position (AVR contact shoe flush with the
workpiece) and then continue sawing along the cut-
ting line.
9 Care and maintenance
CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.
9.1 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 recom-
mended that the power tool is inspected by Hilti. This
will help to extend the life of the power tool and avoid
unnecessary repair costs.
9.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
The outer casing of the power tool is made from impact-
resistant 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
