EXPLANATION OF SYMBOLS ON TOOL/BATTERY
3 Read the instruction manual before use
4 Batteries may explode when disposed of in fire, so do not
burn battery for any reason
5 Store tool/charger/battery in locations where temperature
will not exceed 50°C
6 Do not dispose of electric tools and batteries together
with household waste material
USE
•
Combined switch for on/off and speed control A 7
- control the speed steplessly from zero to maximum by
putting less or more pressure on the trigger A 8
•
Charging battery
! read the safety warnings and instructions
provided with the charger
•
Removing/installing the battery 2
•
Attaching belt clip 9 *NOT STANDARD INCLUDED
- attach the belt clip K to the tool with a screw L *NOT
STANDARD INCLUDED.
Battery level indicator q
•
- press the battery level indicator button H to show the
current battery level q a
! when the lowest level of the battery indicator
starts flashing after pressing button H q b, the
battery is empty
! when 2 levels of the battery indicator start flashing
after pressing button H q c, the battery is not
within the allowable operating temperature range
•
Halo light y
Halo light automatically lights on when activating the on/
off switch
! when LED-light starts flashing, the battery
protection is activated (see below)
•
Battery protection
The tool is suddenly being switched off or prevented from
being switched on, when
- the load is too high --> remove load and restart
- the battery temperature is not within the allowable
operating temperature range of -20 to +50°C --> 2
levels of the battery level indicator start flashing when
pressing button H q c; wait until battery has returned
within the allowable operating temperature range
- the battery is nearly empty (to protect against
deep discharge) --> a low battery level or flashing low
battery level q b is shown by the battery level indicator
when pressing button H; charge battery
! do not continue to press the on/off switch after the
tool is switched off automatically; battery may be
damaged
•
Changing direction of rotation w
- when not properly set in left/right position, switch A 2
cannot be activated
! change direction of rotation only when tool is at a
complete standstill
•
Changing sockets e
- for removing a socket, simply pull it off square drive C
- for mounting simply push a socket onto square drive C
until it locks into place
! only use sockets with a 1/2" square drive
! do not use damaged sockets
•
Mode selection r
Press the speed button G to select the desired tightening
mode when the tool is set to forward rotation:
Low speed mode t a, b, c
- tightening when fine adjustment is needed
- for smaller bolts and nuts
Medium speed mode t d, e, f
- tightening when medium force and speed are needed
- for conducting mechanical repairs
High speed mode t g, h, i
- tightening when high force and speed are needed
- for assembling steel frames
Press the mode button F to toggle between normal
loosening mode, reverse control modes and nut busting
mode when the tool is set to reverse rotation:
Low speed mode t a
- loosening when fine adjustment is needed
- for smaller bolts and nuts
Medium speed mode t d
- loosening when medium force and speed are needed
- for conducting mechanical repairs
High speed mode t g
- loosening when high force and speed are needed
- for disassembling steel frames
Reverse control modes t b, e, h
- for loosening bolts and nuts when different force and
speed are desired
- stops when the bolt is loosened
Nut busting mode t c, f, i
- for disassembling rusty, old bolts/nuts
- loosening with maximum torque
! work mode can be changed only when any mode-
indicator light is shining and the trigger switch is
not depressed
! both reverse control mode and nut busting mode
are available only when the tool is set to reverse
rotation
! since the nut busting mode provides a fixed
impact force, the speed button will not be able to
adjust the impact force in the nut busting mode
The work mode will be stored in memory and reactivated
the next time the tool is turned on or when the direction of
rotation has been changed.
•
Holding and guiding the tool u
! while working, always hold the tool at the grey grip
area(s)
- keep ventilation slots D 2 uncovered
- do not apply too much pressure on the tool; let the tool
do the work for you
APPLICATION ADVICE
•
Use the appropriate sockets
•
When tightening a bolt or nut, do not over-tighten. As the
force of the impact wrench can break the fastener. Hold
the tool aligned with the bolt or nut to prevent damage to
the head of the fastener.
•
The torque depends on the impact duration. Maximum
torque is achieved after an impact duration of 6-10
seconds.
! always check tightening torque with a torque
wrench
•
For an optimal use of the tool a steady pressure on the
bolt is required, especially while removing a fastener.
