16 | English

– Strength properties of the material being screwed/bolted

together

– Lubrication conditions at the screw/bolt connection

The following application cases result accordingly:

– A hard seat is a metal-to-metal screw application which

uses washers. After a relatively short impact duration, the

maximum torque is achieved (steep characteristic curve).

An unnecessarily long impact duration only causes dam-

age to the machine.

– A spring-loaded seat is also a metal-to-metal screw ap-

plication but uses spring washers, disc springs, studs or

screws/nuts with conical seats. It is also called a spring-

loaded seat when extensions are used.

– A soft seat is a screw application of e.g. metal on wood or

a screw application that uses lead washers or fibre wash-

ers as backing.

For a spring-loaded seat, as well as for a soft seat, the max-

imum tightening torque is lower than for a hard seat. A much

longer impact duration is also required.

Tips

Before screwing larger, longer screws into hard materials, it

is advisable to pre-drill a pilot hole with the core diameter of

the thread to approx. 2/3 of the screw length.

Note: Ensure that no metal particles enter the power tool.

Recommendations for optimal handling of the battery

Protect the battery against moisture and water.

Only store the battery only within a temperature range of -20

to 50 °C. Do not leave the battery in your car in the summer,

for example.

Occasionally clean the ventilation slots on the battery using a

soft brush that is clean and dry.

A significantly reduced operating time after charging indic-

ates that the battery has deteriorated and must be replaced.

Follow the instructions on correct disposal.

Maintenance and Service

Maintenance and Cleaning

u Clean the air vents on your power tool regularly. The

motor’s fan will draw the dust inside the housing and ex-

cessive accumulation of powdered metal may cause elec-

trical hazards.

u Remove the battery from the power tool before carry-

ing out work on the power tool (e.g. maintenance,

changing tool, etc.). The battery should also be re-

moved for transport and storage. There is risk of injury

from unintentionally pressing the on/off switch.

u To ensure safe and efficient operation, always keep

the power tool and the ventilation slots clean.
