1. INTRODUCTION
The Arbortech AS170 is designed and
manufactured in Australia, using only the highest
quality components and manufacturing processes.
The unique patented orbital cutting action of two
reciprocating blades, allows cutting of brick, mortar
and masonry faster than traditional reciprocating
saws.
This cutting action also produces minimal amounts
of airborne dust, offering a safe and controllable
operation, with the ability to cut to a depth of
170mm (6 3/4”), cut square corners, and make
variable width cuts. The AS170 is ideally suited to a
variety of tasks including:
• removalofmortarfor“tuckpointing”ofbrick
walls.
• removalofsinglebricksfromwalls.
• cuttingofbrickswithoutdamagetoadjacent
areasor“blow-out”stitching,keyingortoothing
ofbrickwalls“chasing”cutsforconduitsand
similar items into walls.
• cuttingholesinwallsorothersurfaces.
• inishingcornercutsinwalls.
• cuttingindirtywood.
• cuttingwoodintheground.
• treerootremoval.
• pruningtrees.
The tool can be itted with a range of blades to
best suit different applications.

ENSURE CORRECT OPERATION.
2. GENERAL SAFETY RULES
WARNING! Read all instructions. Failure to follow
all instructions listed below may result in electric
shock,ireand/orseriousinjury.Theterm“power
tool” in all of the warnings listed below refers to your
mains-operated (corded) power tool or batteryoperated (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
lammable 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. Unmodiiedplugsandmatchingoutletswill
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.
2
AS170 Owners Manaul Australia - 161213.indd 2
17/12/2013 12:23 pm
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 inluence of drugs, alcohol or medication. A
moment of inattention while operating power tools
mayresultinseriouspersonalinjury.
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
reducepersonalinjuries.
c) Avoid accidental starting. Ensure the switch
is in the off-position before plugging in. Carrying
powertoolswithyouringerontheswitchor
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
resultinpersonalinjury.
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.Looseclothes,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
toolwilldothejobbetterandsaferattheratefor
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 qualiied
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.

4.1 AS170 Tool description
The AS170 is designed to cut rigid materials
suchasmortar,clayiredbricks,plasterboard,
ibreboard,weatherboardandwood.TheAS170
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
someslipincaseofthebladesjamming.The belt
tension must be checked after the irst 5 hours of
use. It is easily tightened by removing the plastic
coverandistensionedusingtheadjustableidler
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.

6. OPERATION
6.1 Setup
The AS170 is supplied ready for operation. However
in some cases the blades may need to be changed
to suit the application.
Before changing
blades, the guard
around the blade
mounts must be levered
gently out of its groove
at the front of the tool
and swung away to
give access to the cap
screws. (See Fig.1)
Usethe“Iankey”
supplied to loosen and
remove the cap screws
securing the blades,
then remove the blades

Fig.1
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(ig.4).

housing. (Fig.5 & 6)
Tostartthecut,holdthetoolirmlyinyourhands
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.
CAUTION: Do Not allow the forward or rear end of
the blades to hammer onto hard surfaces (shown in
igs:10,11&13)asthiswilldamagethebladesand
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.
While cutting, move the tool and blade in a slow
“sawing”motion,whichimprovesthecutrate,

CAUTION: DO NOT operate the tool with loose
blades. If blades should come loose while
operating, the blade mounts and threads can
becomedamaged,requiringsigniicantrepairsto
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”ofthebladeperipheryoccurs,the
blades are running too hot. This occurs when the
blades become worn, too much force being used,
insuficient“sweeping”motionbytheoperator,or
material being too hard.
IMPORTANT To ensure optimal performance and
reduce load on motor, Blades should be kept sharp.
8. ACCESSORIES
If excessive slipping has occurred, the pulleys
can become worn. A worn pulley is evidenced by
thegroovehavinglostitswelldeined“V”shape,
resulting in a rounded or flattened groove. To
replace either pulley, contact your ARBORTECH
authorised service centre.
