2. GENERAL SAFETY RULES
WARNING! Read all instructions. Failure to follow
all instructions listed below may result in electric
shock,reand/orseriousinjury.Theterm“power
tool” in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-
operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids,gases or dust. Power tools
create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause you
to lose control
2) Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodiedplugsandmatchingoutletswill
reduce risk of electric shock
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.

3
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
mayresultinseriouspersonalinjury.
b) Use safety equipment. Always wear eye
protection. Safety equipment such as dust
mask, nonskid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reducepersonalinjuries.
c) Avoid accidental starting. Ensure the switch
is in the off-position before plugging in. Carrying
powertoolswithyourngerontheswitchor
plugging in power tools that have the switch on
invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
resultinpersonalinjury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts.Looseclothes,jewellery
or long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct power
toolwilldothejobbetterandsaferattheratefor
which it was designed.
b) Do not use the power tool if the switch does
not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are dangerous
in the hands of untrained users.
e) Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tools operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits
etc. in accordance with these instructions and
in the manner intended for the particular type
of power tool, taking into account the working
conditions and the work to be performed. Use
of the power tool for operations different from those
intended could result in a hazardous situation
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
NOTE: Refer to the assembly (section 5) for a list
of user replacable parts.

4. FUNCTIONAL DESCRIPTION
4.1 AS170 Tool description
The AS170 is designed to cut rigid materials
suchasmortar,clayredbricks,plasterboard,
breboard,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.

Select the correct blades for the cutting task and
mount each with their cap screws . Verify that the
surfaces of the blade mounts, conrod thread and
screws are clean and free of grit or lubricant before
tting.Ensuretheguardcanbeclosedbeforexing
thebladestotheconrod(Seeg.2).
NOTE: Always use matched pairs of blades.
Never mix used blades with new blades. Use only
the bolts supplied with the tool.
Usethe“Iankey”(see
g.2),totightenthe
blade mounting screws
until the torque indicator
coildeectssufciently
so that the sides meet.
The“IanKey”will
tighten the bolts to the
required 18Nm (13.2
ft lb).
Fig.3
NOTE: Blades are a wearing part. In normal
operation, blade life may vary with the hardness
of materials cut.
CAUTION:
Do not operate the tool
if the blades are loose.
Operation with loose
blades will severely
damage the blade mount
& bolts requiring repair.
Check that the teeth of
the blades are lightly
contacting, or within
approximately 1.5mm
(1/16”) of contacting each
other(g.4).

If the gap between the blades is too large, remove
andgentlybentinwardtoadjustthegap.
Ensure that both blades are aligned vertically to the
tool(Seeg.4).
CAUTION: If the blades rub against each other
anywhere other than within 25mm/1” of the cutting
edge, or contact force is high, it is possible to
overload the tool and cause premature belt wear.
Swing the guard to its groove at the front of the tool
andsnapitintoplace.(Seeg.1)
6.2 Operation

CAUTION: During
operation the AS170
may cause hand-arm
vibration, which can result
in fatigue or discomfort
after long periods of
continuous use. Vibration
will increase with the
hardness of material.
Do not operate the
tool if discomfort is
experienced, and ensure
thatsufcientrestperiods
are taken during cutting.
For further information,
contact the manufacturer.

Hold the tool by both the top handle and the motor
housing. (Fig.5 & 6)
Tostartthecut,holdthetoolrmlyinyourhands
and apply the middle of the blade cutting edge to
the work, keeping in mind that the direction of cut is
towards the rear of the blades.
While cutting, move the tool and blade in a slow
“sawing”motion,whichimprovesthecutrate,
reduces concentrated heat build-up and evens the
wearontheblades.(Seeg.8&9)

CAUTION: Do Not allow the forward or rear end of
the blades to hammer onto hard surfaces (shown in
gs:10,11&13)asthiswilldamagethebladesand
tool. If unintentional hammering occurs, stop the tool
or withdraw it from the cut immediately.
When using any of the blade types, avoid
hammering of the ends of the blades into the ends
of the cut by using a slow rocking and sweeping
motion. For best performance try to ensure that the
teeth are the only part of the blade in contact with
the workpiece.
CAUTION: Take care when setting the tool down to
avoid chipping the tungsten carbide teeth.

Accessories

10
Toreducetheriskofinjury,onlyARBORTECH,
accessories should be used with this product.
Recommended accessories for use with your tool
are available at extra cost from your local dealer or
authorised service centre.
Repairs
If you need any assistance in locating any
accessory, or general tool query please contact
ARBORTECH. www.arbortech.com.au
Brushes
TheAS170isttedwithAuto-cutoffbrushes.When
the brushes are worn below minimum length they
stop tool operation reducing internal motor damage.
Contact your local dealer or authorised service
center for brush replacement.
7.2 V Belt and Pulleys
CAUTION: The V-Belt should be re-tensioned after
therst5hoursofuse.
To access these items, remove the 4 screws holding
the plastic cover on the right side of the tool (see
g.14).Inspectthebeltforcorrecttensionandsigns
of damage. If tensioning is required, loosen the the
tension idler nut (one turn only). Slide the tension
idler outward to increase the tension to the value
noted in the General Specifications in Section
3 and re-tighten. If belt replacement is required,
loosen the tensioner idler, replace the belt and re-
tensiontheidlerasspecied.
Tension Idler
Cover
Fig.14
If excessive slipping has occurred, the pulleys
can become worn. A worn pulley is evidenced by
thegroovehavinglostitswelldened“V”shape,
resultinginaroundedorattenedgroove.To
replace either pulley, contact your ARBORTECH
authorised service centre.
7.3 Blade Mount Bolts and Threads
The blade cap screws should be regularly checked
for correct torque (18Nm.)(13.2 ft lb).Whenever
blades are changed, the bolt and conrod threads
should be checked to ensure they are not worn or
lledwithdebris.UseonlygenuineARBORTECH
spares and do not lubricate bolts, threads or conrod
mating surfaces.
Fig.15
CAUTION: DO NOT operate the tool with loose
blades. If blades should come loose while
operating, the blade mounts and threads can
becomedamaged,requiringsignicantrepairsto
the tool.
7.4 Tooth Sharpness
With use, the blades will become dull and the
cutting performance will decrease. This can be
largely restored by re-sharpening the teeth. To
re-sharpen blade teeth, use the ARBORTECH
Sharpening disk (BLA.FG.SHARP001) Occasionally,
if very hard materials are cut, or the teeth impact a
hard surface at an odd angle, teeth may become
chipped or broken. The blades can still be used,
but cutting performance will be reduced.
If“blueing”ofthebladeperipheryoccurs,the
blades are running too hot. This occurs when the
blades become worn, too much force being used,
insufcient“sweeping”motionbytheoperator,or
material being too hard.
IMPORTANT To ensure optimal performance and
reduce load on motor, Blades should be kept sharp.
8. ACCESSORIES
8.1 Dust Extraction
TheAS170shouldbettedwithadustextraction
funnel,whichsignicantlyreducesairborneand
heavy dust when used correctly. It consists of a
ttingattachedtotheundersideofthealuminium
housingandanadjustableextractionfunnelwhich
isreplaceable.Thedustextractionttinghasa
standard 30mm (1 3/16”) bore.

11
NOTE: Failure to use the dust extraction funnel
when cutting masonry materials will cause
excessive wear of electrical components. Damage
caused by dust will lead to premature failure of the
motor, which will affect the warranty.
CAUTION: Verify that the vacuum machine being
usedhasaltersystemappropriateforthe
materialbeingcut.Incorrectltrationcanresultin
inadequate dust control and also possible damage
to the vacuum machine.
