Blades

General

WARNING! Cutting plastics with a diamond

!blade can cause kickback when the material melts due to the heat produced when cutting and sticks to the blade.

WARNING! Diamond blades get very hot

!when used. An overheated blade is a result of improper use, and may cause deformation of the blade, resulting in damage and injuries.

•Diamond blades consist of a steel core provided with segments that contain industrial diamonds.

Water cooling

WARNING! Cool diamond blades for wet

!cutting continuously with water to prevent overheating, which may deform the blade and cause damage to the blade and injury to the user.

•Water cooling must always be used.When wet cutting, the blade is continuously cooled to prevent overheating.

Diamond blades for different materials

•Diamond blades are ideal for masonry, reinforced concrete and other composite materials.

•We offers a number of blades for different materials in its range. Check with your Husqvarna dealer to see which blades are best suited for your usage.

Sharpening diamond blades

•Always use a sharp diamond blade.

•Diamond blades can become dull when the wrong feeding pressure is used or when cutting certain materials such as heavily reinforced concrete.Working with a blunt diamond blade causes overheating, which can result in the diamond segments coming loose.

•Sharpen the blade by cutting in a soft material such as sandstone or brick.

Vibrations on diamond blades

•The blade can become out of round and vibrate if a too high feed pressure is used.

•A lower feed pressure can stop the vibration. Otherwise replace the blade.

Drive

On account of the machine’s unique design the driving power is not transferred at the centre of the blade.

The ﬂanges on the two guide rollers run in the blade’s groove. Springs on the guide rollers press out the rollers, which in turn press the V-shaped edge on the inside diameter of the blade against the V-shaped groove in the drive wheel. The drive wheel is ﬁtted on an axle which is driven by the engine via a drive belt.

This allows a total cutting depth of 260 mm (10 inches) with a 350 mm (14 inches) diamond blade.

Checking wear

As the blade is used the inside diameter and the groove in the drive wheel become worn.

The ring cutter will also work well in the future if:

•the drive wheel is not too worn

1)New

2)Worn

•the guide rollers are not too worn

1)New, 3 mm (0.12’’)

2)Worn, ≤ 1,5 mm (0.06’’)
