Narex EBU 115-9, Original Operating Manual

e) 

Do not attach a saw chain woodcarving blade or toothed saw 

blade.

 Such blades create frequent kickback and loss of control.

Safety warnings specific for grinding and 

cutting‑off operations:

a) 

Use only wheel types that are recommended for your power 

tool and the specific guard designed for the selected wheel.

Wheels for which the power tool was not designed cannot be ade-

quately guarded and are unsafe.

b) 

Use only the specific guard designed for the selected wheel. 

The guard must be securely attached to the power tool and 

positioned for maximum safety, so the least amount of wheel 

is exposed towards the operator.

 The guard helps to protect the 

operator from broken wheel fragments and accidental contact 

with the wheel.

c) 

Wheels must be used only for recommended applications. For 

example: do not grind with the side of cut‑off wheel.

 Abrasive 

cut-off wheels are intended for peripheral grinding, side forces ap-

plied to these wheels may cause them to shatter.

d) 

Always use undamaged wheel flanges that are of correct size 

and shape for your selected wheel.

 Proper wheel flanges support 

the wheel thus reducing the possibility of wheel breakage. Flanges 

for cut-off wheels may be different from grinding wheel flanges.

e) 

Do not use worn down wheels from larger power tools.

 Wheels 

intended for larger power tools are not suitable for the higher 

speed of a smaller tool and may burst.

Additional safety instructions for cutting‑off 

operations:

a) 

Do  not “jam” the cut‑off wheel or apply excessive pressure. 

Do not attempt to make an excessive depth of cut.

 Overstress-

ing the wheel increases the loading and susceptibility to twisting 

or binding of the wheel in the cut and the possibility of kickback or 

wheel breakage.

b) 

Do not position your body in line with and behind the rotating 

wheel.

 When the wheel, at the point of operation, is moving away 

from your body, the possible kickback may propel the spinning 

wheel and the power tool directly at you.

c) 

When wheel is binding or when interrupting a cut for any rea‑

son, switch off the power tool and hold the power tool motion‑

less until the wheel comes to a complete stop. Never attempt 

to remove the cut‑off wheel from the cut while the wheel is in 

motion otherwise kick‑back may occur.

 Investigate and take cor-

rective action to eliminate the cause of wheel binding.

d) 

Do not restart the cutting operation in the workpiece. Let the 

wheel reach full speed and carefully reenter the cut.

 The wheel 

may bind, walk up or kickback if the power tool is restarted in the 

workpiece.

e) 

Support panels or any oversized workpiece to minimise the risk 

of wheel pinching and kick‑back.

 Large workpieces tend to sag 

under their own weight. Supports must be placed under the work-

piece near the line of cut and near the edge of the workpiece on 

both sides of the wheel.

f) 

Take extra caution when making a “pocket cut” into existing 

walls or other blind areas.

 The protruding wheel may cut gas or 

water pipes, electrical wiring or objects that can cause kickback.

Safety Warnings Specific for Sanding 

Operations:

a) 

Do  not use excessively oversized sanding disc paper. Follow 

manufacturers recommendations when selecting sanding 

paper.

 Larger sanding paper extending beyond the sanding pad 

presents a laceration hazard and may cause snagging, tearing of 

the disc or kickback.

Safety Warnings Specific for Wire Brushing 

Operations:

a) 

Be aware that wire bristles are thrown by the brush even dur‑

ing ordinary operation. Do not overstress the wires by applying 

excessive load to the brush.

 The wire bristles can easily penetrate 

light clothing and/or skin.

b) 

If the use of a guard is recommended for wire brushing, do not 

allow any interference of the wire wheel or brush with the 

guard.

 Wire wheel or brush may expand in diameter due to work 

load and centrifugal forces.

Information about noise level and 

vibrations

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

pA

 = 90.2 dB (A).

Acoustic power level L

wA

 = 101.2 dB (A).

In accuracy of measurements K = 2 dB (A).

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

The weighted value of vibrations affecting hands and arms 

a

h

 = 20.25 m.s

-2

.

In accuracy of measurements K = 1.5 m.s

-2

.

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

cordance with the test conditions stipulated in EN 60745 and are intend-

ed 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 ap-

plications, with other tools or is not maintained sufficiently 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 estimate 

these values more accurately for a specified time period. This may signif-

icantly reduce the load during the machine operating period.

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 suffi-

cient to supply them with power. Tools are shielded in accordance with 

EN 55014.

Use

The machine is designed for splitting, roughing and brushing metal and 

stone materials without the use of water. For cutting stone, a cutting 

guide is required.
The user himself is liable for any improper use.

Protective elements and their 

assembly 

The grinder may be used with mounted protective guard only!

Attention! Prior to handling the accessories, the power 

supply cable has always to be disconnected from the power 

source socket!

Protective guard

Attention! The protective guard intended only and exclu‑

sively for work with the grinding wheels is the integral part 

of the standard angular grinder outfit.

When cutting, the angular grinder has to be equipped by the protective 

guard intended for work with the cutting wheels; it can be purchased 

in the trade network under the order No. 00 763 301 for dia. 115 mm. 

Failing to use the guard for cutting, you run the increased risk of injury 

and in this case (non-use of the special guard for cutting) the company 

Narex is not liable anyhow for possible harm of health of the user or 

another person injured as the consequence of breach of the safety rules.
Put the protective guard (8a; 8b) on the clamping collet (6). The guide 

lugs (9) must be inserted into the grooves on the clamping collet. Set 

the protective guard (8a; 8b) to the requested working position.
Note: The protective guard has been designed so that no tool may be 

needed for fixing the protective guard in the requested working posi-

tion.

Attention! For safety reasons the clamping bolt (10) has been 

tightened in the manufacturing plant by the torque 3.5 Nm so that 

the safety guard may not be loose on the clamping collet (6), but 

may be swiveled by hand after overcoming the set resistance.

 It is 

necessary to check the mounted protective guard - it may not be loose 

(may not wobble) on the clamping collet. For possible tightening the 

clamping bolt (10) use the hexagonal wrench dia. 4 mm (18) and check 

the torque 3.5 Nm.
