SAFETY INSTRUCTIONS

Use leg-guards recommended for the material to be cut.

Boots with steel toe-caps and non-slip sole

Always have a first aid kit nearby.

General safety precautions

Work area safety

Keep work area clean and well lit. Cluttered or dark areas 
invite accidents.

Do not use the machine in bad weather, such as dense 
fog, rain, strong wind, intense cold, etc. Working in bad 
weather is tiring and often brings added risks, such as icy 
ground.

Never start to work with the power cutter before the 
working area is clear and you have a firm foothold. Look 
out for any obstacles with unexpected movement. Ensure 
when cutting that no material can become loose and fall, 
causing operating injury.Take great care when working on 
sloping ground.

Make sure that no pipes or electrical cables are routed in 
the area to be cut.

Look around you:

   - To ensure that people, animals or other things cannot affect 
your control of the machine.

   - To make sure that none of the above come into contact with 
the cutting blade.

Personal safety

Wear personal protective equipment. See instructions 
under the heading Personal protective equipment.

Never use the machine if you are tired, if you have 
consumed alcohol, or if you are taking other drugs or 
medication that can affect your vision, judgement or co-
ordination.

Never allow anyone else to use the machine without first 
ensuring that they have understood the contents of the 
operator’s manual.

Make sure that no clothes or parts of the body come in 
contact with the cutting equipment when it is rotating.

it is rotating.

The guards for the cutting equipment must always be 
fitted when the machine is running.

position.

Use and care

A power cutter is designed to cut hard materials, such as 
masonry. Observe the increased risk of kickback when 
cutting soft materials. See instructions under the heading 
How to avoid kickback.

Never use a machine that is faulty. Carry out the checks, 
maintenance and service instructions described in this 
manual. Some maintenance and service measures must 
be carried out by trained and qualified specialists. See 
instructions under the heading Maintenance.

Never use a machine that has been modified in any way 
from its original specification.

Do not move the machine when the cutting equipment is 
rotating.

Transport and storage

Do not store or transport the power cutter with the blade fitted.

Store the power cutter in a lockable area so that it is out of 
reach of children and unauthorised persons.

The blade should be removed from the machine after use and 
stored well. Store the blade in the dry.

IMPORTANT! Do not use the power cutter until you have 
read the entire contents of this Operator’s Manual. 
All servicing, in addition to the points listed in the section 
”Control, maintenance and service of the power cutter’s 
safety equipment”, should be carried out by trained service 
specialists.

!

WARNING! Only use the machine in areas 
with good ventilation. Neglect can result in 
serious injury or death.

WARNING! The safety distance for the power 
cutter is 15 metres. You are responsible to 
ensure that animals and onlookers are not 
within the working area. Do not start cutting 
until the working area is clear and you are 
standing firmly.

WARNING! Overexposure to vibration can 
lead to circulatory damage or nerve damage 
in people who have impaired circulation. 
Contact your doctor if you experience 
symptoms of overexposure to vibration. 
These symptoms include numbness, loss of 
feeling, tingling, pricking, pain, loss of 
strength, changes in skin colour or 
condition. These symptoms normally appear 
in the fingers, hands or wrists.

IMPORTANT! K960 Ring may only be used for wet cutting. 
The water cleans and cools both the blade and the 
component parts of the cutting equipment.

IMPORTANT! Never work with a power cutter that is 
damaged or incorrectly adjusted. Check that the blade 
stops rotating when the throttle is released.
