3. Screws
For the same type of screw or fastening, the screw diam-
eter governs the torque.
For the same screw diameter, the screw length and type
of screw head determine the achievable torque.
4. Extensions
The use of extensions, link joints, etc. reduces the torque.
This can be counteracted by driving the screw longer.
5. Base material
The way the screwdriver is used and the material being
screwed into influence the torque.
In concrete base material (concrete screws), hole tol-
erance and different concrete strengths are responsible
for different resistance to penetration.
It is recommended that trials be carried out with prob-
lematic screw fastenings on the jobsite.

Maintenance

Prior to working on the screwdriver, make
sure the switch is in the OFF position and the plug is
pulled out of the electric supply socket / receptacle.
To keep this screwdriver safe and reliable, its mainte-
nance, repair and adjustment should only be carried out
by workshops or customer service centres authorised
by Hilti which use only original Hilti spare parts.
-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 tool is made from impactresis-
tant plastic. Sections of the grip are made from a syn-
thetic rubber material. Never operate the 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 tool. Clean the outside of the
tool at regular intervals with a slightly damp cloth. Do not
use a spray, steam pressure cleaning equipment or run-
ning water for cleaning. This may negatively affect the
electrical safety of the tool.
