1919 - 002 - 23.01.2023 9

WARNING: Only use diamond blades

for wet cutting. The diamond blade must be

applicable to the same speed or a higher

speed than the value given on the product

type plate. Only use diamond blades that

are in compliance with national or regional

standards, for example EN13236 or ANSI

B7.1.

The cutting blade manufacturer gives warnings and

recommendations for the operation and correct

maintenance of the cutting blade. Those warnings are

supplied with the cutting blade.

Diamond blades

WARNING: Make sure that the

direction of rotation for the diamond blade

shown on the diamond blade aligns with the

direction of rotation shown on the product.

CAUTION: Always use a sharp

diamond blade.

There is a wide range of diamond blades that is used

for different operations. From new made concrete to

concrete and asphalt that has become hard and for

different hardness classes.

Diamond blades has a steel core with segments that are

made of industrial diamonds.

Water cooling system

Always use water during operation to keep the

temperature of the diamond blades down. The water

cooling system also increases the lifetime of the

diamond blades and prevents dust buildup.

Make sure that the water supply is not clogged.

To sharpen the diamond blades

Diamond blades can become blunt if you use an

incorrect feeding pressure or when you cut materials

such as hard reinforced concrete. If you use a blunt

diamond blade it becomes too hot, which can cause the

diamond segments to come loose.

• Decrease the cutting depth and the engine speed

for a short time to sharpen the diamonds on the

diamond blade.

Diamond blades for wet cutting

WARNING: Always use a blade flange

dimension that is specified for the current

blade dimension. Do not use blade flanges

that are damaged.

WARNING: Use approved respiratory

protection when you clean or replace the air

filter. Discard used air filters correctly. The

dust in the air filter is dangerous to your

health.

WARNING: Do not clean the air filter

with compressed air. This causes damage to

the air filter and the risk increases that you

breathe the dangerous dust.

CAUTION: Always replace a damaged

air filter, or the dust will go into the engine

and cause engine damage.

• For information on how to clean and replace the air

filter, refer to the operator's manual for the engine.

To examine the spark plug
