Before Use; Operation - Hilti SF 4000-A Bedienungsanleitung

d)The batteries must be disposed of correctly on reach-
ing the end of their life (see section 10).
e)Do not charge or continue to use damaged batter-
ies (e.g. batteries with cracks, broken parts, bent
or pushed-in and/or pulled-out contacts).

6. Before use

1. It is essential that the safety precautions printed in
these operating instructions are read and observed.
2. A new battery must be charged correctly for the first
time before use:
– charged normally for 24 hours with the SFC 7/8 H
charger, or
– charged for 12 hours using the conditioning func-
tion of the SFC 7/18, C7/24, C7/36-ACS or TCU 7/36
charger. This will ensure that the cells form cor-
rectly. Incorrect initial charging may have a perma-
nent, negative effect on battery capacity.
Additional instructions
– The tool may be used only with SFB 180 or SFB 185
batteries.
– Battery performance drops at low temperatures.
– Batteries should be stored at room temperature.
– Never store batteries where they are exposed to the
heat of the sun, on a radiator, behind a motor vehicle
windscreen or at a window.
– Never use the battery until the cells become fully dis-
charged. Change to the second battery as soon as a
drop in performance is noticed and recharge the bat-
tery immediately so that it is ready for re-use.
– Use bits with a standard
The battery cannot be charged through the belt adap-
tor. When charging, always insert the battery directly in
the charger

7. Operation

Setting the depth gauge (screwdriving depth)
By adjusting the depth gauge, the screw can be driven
flush, beneath the surface or left projecting. Each incre-
ment is equal to an adjustment of ± 0.25 mm.
– Turn the depth gauge to the left
= The screw is driven deeper I.
– Turn the depth gauge to the right
= The screw is driven less deeply II.
Setting forward or reverse rotation
The direction of rotation of the driving spindle can be
selected by operating the forward / reverse push switch
. An interlock prevents operation of the switch while
the motor is running. When in the middle position, the
on / off switch is locked
– Push the forward / reverse switch to the right (tool in
the working position)
= reverse I.
– Push the forward / reverse switch to the left (tool in
the working position)
= forwards II.
Changing the bit
1. Grip the depth gauge and pull it forwards until the
snap-lock connection releases. The depth gauge can
then be pulled off towards the front end of the tool
.
2. Position the depth gauge on the worn bit
3. Pull the depth gauge upwards and pull out the bit
towards the front end of the tool
4. Insert a new bit.
5. Position the depth gauge on the tool and press it in
until it engages.
Changing the bit holder
1. Grip the depth gauge and pull it forwards until the
snap-lock connection releases. The depth gauge can
then be pulled off towards the front end of the tool
.
2. Grip the plastic part of the bit holder and pull it towards
the front end of the tool while pressing it away from
the gear housing .
3. Insert a new bit holder.
4. Position the depth gauge on the tool and press it in
until it engages.
Switching on / off
1. Use the forward / reverse push switch to select the
direction of rotation.
2. The speed of the tool can be controlled smoothly
between zero and maximum by pressing the on / off
switch slowly.
Should the motor stall for longer than 2–3 seconds, the
tool must be switched off in order to avoid damage to it.
Selecting sustained operation
The lockbutton for sustained operation can be used to
