Narex ESR 800, Original Operating Manual

English

15

d) 

Remove any adjusting key or wrench before turning the 

power tool on.

 A wrench or a key left attached to a rotating 

part of the power tool may result in personal injury.

e) 

Do not overreach. Keep proper footing and balance at all 

times.

 This enables better control of the power tool in unex‑

pected situations.

f) 

Dress properly. Do  not wear loose clothing or jewellery. 

Keep your hair, clothing and gloves away from moving 

parts.

 Loose clothes, jewellery or long hair can be caught in 

moving parts.

g) 

If devices are provided for the connection of dust extrac‑

tion and collection facilities, ensure these are connected 

and properly used.

 Use of dust collection can reduce dust‑re‑

lated hazards.

4)  Power tool use and care

a) 

Do not force the power tool. Use the correct power tool for 

your application.

 The correct power tool will do the job better 

and safer at the rate for which it was designed.

b) 

Do not use the power tool if the switch does not turn it on 

and off.

 Any power tool that cannot be controlled with the 

switch is dangerous and must be repaired.

c) 

Disconnect the plug from the power source and/or the 

battery pack from the power tool before making any ad‑

justments, changing accessories, or storing power tools.

Such preventive safety measures reduce the risk of starting 

the power tool accidentally.

d) 

Store idle power tools out of the reach of children and 

do  not allow persons unfamiliar with the power tool or 

these instructions to operate the power tool.

 Power tools 

are dangerous in the hands of untrained users.

e) M

aintain power tools. Check for misalignment or binding 

of moving parts, breakage of parts and any other condi‑

tion that may affect the power tool’s operation. If dam‑

aged, have the power tool repaired before use.

 Many acci‑

dents are caused by poorly maintained power tools.

f) 

Keep cutting tools sharp and clean.

 Properly maintained 

cutting tools with sharp cutting edges are less likely to bind 

and are easier to control..

g) 

Use the power tool, accessories and tool bits etc. in ac‑

cordance 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.

5) Service

a) 

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.

Special Safety Instructions

a) 

While carrying out activities during which the clamping 

head may get in contact with electric cable or its own pow‑

er cord, keep holding the machine by touching the insulat‑

ed surfaces only.

 Clamping head contact with live electric 

cable may result in conductivity of non‑isolated metal parts 

of the tool and electrical shock injury to user.

Information about noise level and 

vibrations

The values have been measured in conformity with EN 60745.
Acoustic pressure level L

pA

 = 95 dB (A).

Acoustic power level L

wA

 = 106 dB (A).

In accuracy of measurements K = 3 dB (A).

ATTENTION! Noise is generated during work!
Use ear protection!

The weighted value of vibrations affecting hands and arms 

a

h

 = 14.66 m.s

-2

.

In accuracy of measurements K = 1.5 m.s

-2

.

The emission values specified (vibration, noise) were measured in 

accordance with the test conditions stipulated in EN 60745 and are 

intended for machine comparisons. They are also used for making 

preliminary estimates regarding vibration and noise loads during 

operation.
The emission values specified refer to the main applications for 

which the power tool is used. If the electric power tool is used for 

other applications, with other tools or is not maintained sufficient-

ly prior to operation, however, the vibration and noise load may be 

higher when the tool is used.
Take into account any machine idling times and downtimes to esti-

mate these values more accurately for a specified time period. This 

may significantly reduce the load during the machine operating 

period.

Intended use

Electric impact wrench is designed for screwing in (tightening)/

screwing out out (looseining) bolts and nuts with hexagonal head.
Being leightweight and powerful in tightening, the electric impact 

wrench is fit for industrial and workshop use, repair and mainte-

nance, construction etc.
User takes full responsibility for any consequences arising from use 

other than the intended use.

How it works

Spindle (3) with a  tool is driven by electromotor gears and the 

springed impact mechanism.

It is a twO‑stage process:

1. Screwing;
2. Tightening.

Impact mechanism is put into operation after the bolted joint has 

been tightened up - motor is loaded.
At this moment, the impact mechanism transforms the power into 

even rotational impacts. Loosening is a reversed process.

Double insulation

To ensure maximum safety of the user our tools are designed and 

built to satisfy applicable European standards (EN standards). Tools 

with double insulation are marked by the international symbol of 

a double square. These tools must not be grounded and a twO-wire 

cable is sufficient to supply them with power. Tools are shielded in 

accordance with EN 55014.

Belt clip attachement

Attention! Risk of an electric shock! Please make sure 

to unplug the tool before any handling.

Put the tool on the even surface (e.g. workbench). Insert the belt 

clip (4) into the fit of the belt clip (6) with the bent end pointing 

towards this fit. Use an appropriate screwdriver to secure the belt 

clip (5) with the attachement bolt (5). Belt clip (4) can be attached 

to the device both from right or left side of the handgrip. Please 

avoid the inverse mounting of the belt clip (4). Keep the orienta-

tion of belt clip (4) as shown in the figure.
