alcohol or medicines. A moment of inattention while 

operating power tools may cause damage serious 

personal.

USE PPE’S.

Use protection glasses according EN166. Use 

protection masks according EN149. If required by the 

type of work, use other precise PPE.

DO NOT WORK ON TIPTOES.

Keep your feet on the ground and balance at all 

times. This enables better control of the power tool in 

unexpected situations.

DRESS PROPERLY.

Do not wear loose clothing or jewelry. Keep your hair, 

clothing and gloves away from moving parts. Loose 

clothes, jewelry or long hair can be caught in moving 

parts. If there are devices for connecting means for 

extracting and collecting dust, make sure they are 

connected and properly used. The use of these 

devices can reduce dust related hazards.

ELECTRICAL SAFETY.

The plug of the power tool must match with the base 

of the socket. Never modify the plug in any way. 

Do not use any adapter plug with earthed power 

tools.  Unmodified  plugs  and  matching  bases  will 

reduce the risk of electric shock. Avoid body contact 

with grounded surfaces such as pipes, radiators, 

cookers and refrigerators. There is an increased 

risk of electric shock if your body is grounded. Do 

not expose power tools to rain or wet conditions. 

Water entering the power tool will increase the risk 

of electric shock.

DO NOT ABUSE THE CORD. 

Never use the cord to carry, lift or unplug the power 

tool. Keep the cord away from heat, oil, sharp edges or 

moving parts. Damaged or entangled cords increase 

the risk of electric shock. When operating a power tool 

outdoors, use an extension cord suitable for outdoor 

use. The use of an extension cord suitable for outdoor 

use reduces the risk of electric shock. If the use of a 

power tool in a damp location is unavoidable, use a 

power protected by a residual current device (RCD). 

The use of an RCD reduces the risk of electric shock.

AVOID ACCIDENTAL STARTING.

Make  sure  the  switch  is  in  “off”  position  before 

connecting to the network, or when taking or carrying 

the power tool. Carrying power tools with your finger 

on the switch or plugging in power tools that have the 

switch in “on” position invites to accidents. Remove 

keys or tools before starting the power tool. A left key 

or tool attached to a rotating part of a power tool can 

cause personal injury. Never lay this power tool down 

until the accessory has come to a complete stop. The 

spinning accessory may grab the surface and pull 

this power tool out of your control. Do not run this 

power tool while carrying it at your side. Accidental 

contact with the spinning accessory could snag your 

clothing, pulling the accessory into your body.

USE AND CARE OF POWER TOOLS.

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 conceived.  Do not use the power tool if 

the switch cannot be positioned to “off” and “on” 

position. Any power tool that cannot be controlled 

with the switch is dangerous and must be 

repaired. Remove the plug from the power supply 

and/or  battery  before  making  any  adjustments, 

changing accessories or storing the power tool. 

Such preventive safety measures reduce the risk 

of starting the power tool accidentally. Do not use 

accessories  which  are  not  specifically  designed 

and recommended by Werku

®

. Just because the 

accessory can be attached to this power tool, it 

does not assure safe operation. The rated speed 

of the accessory must be at least equal to the 

maximum speed marked on this power tool. 

Accessories running faster than their rated speed 

can break and fly apart. The outside diameter and 

the thickness of your accessory must be within 

the capacity rating of this power tool. Incorrectly 

sized accessories cannot be adequately guarded 

or controlled. Threaded mounting of accessories 

must match the spindle thread. For accessories 

mounted  by  flanges,  the  arbour  hole  of  the 

accessory  must  fit  the  locating  diameter  of  the 

flange. Accessories that do not match the mounting 

hardware of this power tool will run out of balance, 

vibrate excessively and may cause loss of control. 

Do not use a damaged accessory. Before each 

use, inspect the accessory. If this power tool or 

its accessory is dropped, inspect for damage or 

install an undamaged accessory. After inspecting 

and installing an accessory, position yourself and 

bystanders away from the plane of the rotating 

accessory and run this power tool at maximum no-
