4. FUNCTIONAL DESCRIPTION

4.1 AS160 TOOL DESCRIPTION

The AS160 is designed to cut rigid materials such as mortar, clay fired bricks, plasterboard, fibreboard,

weatherboard and wood. The AS160 uses a variety of blades to suit the material being cut. Blades may also be

changed to suit the required depth or length of cut.

The blades are driven via conrods and a camshaft, which is belt-driven. The V-belt is designed to allow some

slip in case of the blades jamming. It is easily replaced by removing the plastic cover and is tensioned using

the adjustable idler pulley (see section 11.3).

Blades are mounted to the conrods using high tensile Allen™ head bolts.

A replaceable metal guard is provided to limit the maximum cutting depth and prevent the blade mounts from

damaging the surface of the material being cut.

Shock and vibration to the operator are reduced by a rubber-mounted top handle. The top handle is also

designed for comfort when used in a variety of cutting orientations. The rubber bushes on the top handle can

be replaced if they become worn or damaged.
