before engaging the work piece.
6. Never start or operate the tool with fingers or
other objects through the holes in the blades.
7. Use care when handling blades during and
after use . The blades and some areas of the tool
become hot in use.
8. Always ensure that before cutting there are
no hazards such as electrical wiring , pipes or
insulation in the area to be cut.
9. Allow for resting periods to ease the effect
of the vibration of the tool. Use work gloves to
minimise vibration effect on the body.
10. Ensure the dust extraction equipment is
connected and properly used.
11. Keep handles dry, clean and free from oil and
grease.
12. If the guard or other parts appears to be
damaged, it should be carefully checked to
determine that it will operate properly and perform
its intended function.
13. The use of any accessory or attachment other
than those recommended in this instruction manual
may present a risk of personal injury.

4. FUNCTIONAL DESCRIPTION

4.1 AS170 TOOL DESCRIPTION
The AS170 is designed to cut rigid materials
such as mortar, clay fired bricks, plasterboard,
fibreboard, weatherboard and wood. The AS170
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. The belt
tension must be checked after the first 5 hours
of use . It is easily tightened by removing the plastic
cover and is tensioned using the adjustable idler
pulley (see section 7.2).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.

4.2 BLADE DESCRIPTION

The AS170 uses a variety of blades to cut different
materials and different profiles.
General Purpose blades use Tungsten
Carbide teeth and are suited for working
general masonry and "in the ground" cutting.
General Purpose blades are designed to cut
to a depth of 115mm (4 1/2").
Plunge blades use Tungsten Carbide teeth
and have a maximum cutting depth of
4 3/4 "
120mm ( ). Mortar plunge blades can cut
slots of 75mm (3") in length.
