Failure to observe this point may result in damage to the
tool or present a risk of accident. Accordingly, if neces-
sary, have the tool repaired at a Hilti service centre or
authorised Hilti repair workshop.


Always wear protective gloves and suitable

protective goggles when working as saw blades may
break or splinter.
Use clamps or a vice to hold the work. It is safer than
using your hand and it frees both hands to operate the
Form the habit of checking to see that keys and adjust-
ing wrenches are removed from the tool before switching
it on.

Preparation for use

It is essential that the safety precautions print-
ed in these operating instructions are read

and observed.

The supply voltage must correspond to the infor-

mation on the type plate.

If extension cords are used: Only extension cords

of a type approved for the intended use and of ade-

quate cross section may be used. Failure to observe this
point may result in reduced performance of the tool and
overheating of the cord. Damaged extension cords must
be replaced. The recommended cross-sections and max.
length for extension cords are:

Conductor cross-section

Mains voltage

1.5 mm


2.5 mm


100 V

20 m

40 m

230 V

50 m

100 m

Extension cables outdoors
Only suitable approved and correspondingly marked
cables may be used outdoors.

Always stay alert
Always concentrate on your work. Proceed logically and
do not use the tool when your full concentration is not
on the job.


Inserting the blade
Use only blades with a standard




″ shank connection


Unplug the supply cord from the mains socket
to prevent unintentional starting.

b) Check that the connection end of the blade is clean.

Always ensure that the blade clamping mechanism
is kept clean.

c) Turn the blade clamp locking sleeve in a counter-

clockwise direction. Insert the blade in the blade clamp
and press in the locking sleeve. Release the locking
sleeve until it is heard to engage. Check that it is held
securely by pulling on the blade


Note: If the saw blade cannot be inserted into the blade
clamp, turn the locking sleeve a little until the blade is
in the correct clamping position and then release the
locking sleeve.

Removing the insert tool

Unplug the supply cord from the electrical sock-
et to prevent unintentional starting.

b) Turn the locking sleeve and pull out the blade


Wear protective gloves. The insert tool may

be very hot after long periods of use.


Setting the stroke rate
The recommended stroke rate can be pre-selected by
turning the stroke rate adjusting wheel

Ẋ to the desired

setting. When the operating switch is pressed the saw
will then run at the pre-selected stroke rate. The recom-
mended stroke rate settings and information concern-
ing the correct choice of saw blade can be found in the
information supplied with these products and in the cor-
responding table of applications.

Stroke rate selection
(1 = low stroke rate, 4 = high stroke rate)

Material cut

Recommended stroke rate



Wood with embedded nails


Drywall, interior finishing






Non-ferrous metals




Stainless steel


The above settings are recommendations intended to
ensure optimum cutting performance. The optimum set-
ting may differ from these recommendations depending
on the saw blade used, the mains supply voltage and the
sawing technique employed. Use of the wrong stroke rate
setting may result in increased saw blade wear.

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

ẋ. 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.
