Settings And Adjustments; Drive; Fitting The Blade - Husqvarna K960 Ring Operator's Manual

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.
1 Blade
2 Support rollers
3 Drive wheel
4 Guide rollers
5 V-shaped edge
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
A) New
B) Worn
• the guide rollers are not too worn
A) New
B) Worn
• adjustment between the rollers and blade is correct.
The roller setting should be checked twice during the life of
the diamond blade, once after fitting the blade and when the
blade is semi worn.
