Reference Values for Maximum Screw/Bolt Tightening Torques

Calculated from the tensional cross-section; utilization of the yield point 90% (with friction coeffi-

cient μ

total

= 0.12). As a control measure, always check the tightening torque with a torque wrench.

Tips

Before screwing larger, longer screws into hard

materials, it is advisable to predrill a pilot hole

with the core diameter of the thread to approx.

of the screw length.

Maintenance and Service

Maintenance and Cleaning

f Before any work on the machine (e. g.,

maintenance, tool change, etc.) as well as

during transport and storage, set the rota-

tional direction switch to the centre posi-

tion. Unintentional actuation of the On/Off

switch can lead to injuries.

f For safe and proper working, always keep

the machine and ventilation slots clean.

When the battery is no longer operative, please

refer to an authorised after-sales service agent

for Bosch power tools.

If the machine should fail despite the care taken

in manufacturing and testing procedures, repair

should be carried out by an after-sales service

centre for Bosch power tools.
