Keep cutting tools sharp and clean. 

Properly 

maintained cutting tools with sharp cutting edges are 

less likely to bind and are easier to control.

Use the power tool, accessories and tool bits etc. 

in accordance with these instructions, taking into 

account the working conditions and the work to 

be performed. 

Use of the power tool for operations 

different  from  those  intended  could  result  in  a 

hazardous situation.

Service

Have your power tool serviced by a qualified repair 

person using only identical replacement parts.

This will ensure that the safety of the power tool is 

maintained.

Use special care when working corners, sharp 

edges, etc. Avoid bouncing and snagging the 

accessory.

 Corners, sharp edges or bouncing have 

a tendency to snag the rotating accessory and cause 

loss of control or kickback.

Do not attach a saw chain woodcarving blade or 

toothed saw blade.

 Such blades create frequent 

kickback and loss of control over the power tool.

Safety Warnings for Impact Wrenches
Hold power tool by insulated gripping surfaces 

when performing an operation where the cutting 

accessory or fastener may contact hidden wiring.

Cutting accessory and fasteners contacting a “live” 

wire may make exposed metal parts of the power tool 

“live” and could give the operator an electric shock.

Use auxiliary handle(s), if supplied with the tool. 

Loss of control can cause personal injury.

Hold  the  machine  with  a  firm  grip. 

High reaction 

torque can briefly occur while driving in and loosening 

screws.

Secure the workpiece. 

A workpiece clamped with 

clamping devices or in a vice is held more secure than 

by hand.

Always wait until the machine has come to a 

complete stop before placing it down. 

The tool 

insert can jam and lead to loss of control over the 

power tool.

Never use the machine with a damaged cable. Do 

not touch the damaged cable and pull the mains 

plug when the cable is damaged while working. 

Damaged cables increase the risk of an electric shock.

Products sold in GB only: 

Your  product  is  fitted 

with a BS 1363/A approved electric plug with internal 

fuse (ASTA approved to BS 1362). If the plug is not 

suitable for your socket outlets, it should be cut off and 

an appropriate plug fitted in its place by an authorised 

customer service agent. 
The replacement plug should have the same fuse 

rating as the original plug. The severed plug must 

be disposed of to avoid a possible shock hazard 

and should never be inserted into a mains socket 

elsewhere.

Products sold in AUS and NZ only: 

Use a residual 

current device (RCD) with a rated residual current of 

30 mA or less.

PRODUCT DESCRIPTION AND PECIFICATIONS

Read all safety warnings and all 

instructions.

 Failure to follow the warnings 

and instructions may result in electric 

shock, fire and/or serious injury.

Intended Use

 The machine is intended for driving 

in and loosening screws and bolts as well as for 

tightening and loosening nuts within the respective 

range of dimension.

Tool components

Screwing/unscrewing impact wrench.
4 working ½” square bits: 17mm, 19mm, 20mm, 22mm
Fast replacement brush set.
High density polipropilene hard carry case for safety 

transportation.

MOUNTING

Change of useful

Before any manipulation of the power tool, remove the 

mains plug from the socket.

When assembling the tool, make sure that it is firmly 

attached  to  the  tool  holder.  A  tool  that  is  not  firmly       

attached to its housing can become loose and make 

you lose control over it.

housing 

OPERATION

Method of Operation

The tool is driven by an electric motor via a gear and 

impact mechanism.
The working procedure is divided into two phases:

Screwing in

 and 

tightening

 (impact mechanism in 

action).

The impact mechanism is activated as soon as the 

screwed connection runs tight and thus load is put 

on the motor. In this instance, the impact mechanism 

converts the power of the motor to steady rotary 

impacts. When loosening screws or nuts, the process 

is reversed.

Starting Operation

Observe correct mains voltage! The voltage of 

the power source must agree with the voltage 

specified on the nameplate of the machine. Power 

tools marked with 230 V can also be operated with 

220 V.
