Before putting the machine into operation, please read all the enclosed safety rules and
operating instructions.
–SAFETYGUARD –
The angle grinder comes fitted with a miniature chainsaw blade and is ready for use.
The position of the safety guard has been rotated to the correct position.
DO NOT
REMOVE THE SAFETY GUARD WHEN USING THE CHAINSAW BLADE OR ANY
ACCESSORY AND ALWAYS OPERATE THEM WITH THE GUARD IN THE 23
o
TO 45
o
POSITION.
The risk of kickback or binding, however small, is greatly increased with no
safety guard. The guard also protects operator from broken grinding wheel fragments.
IF YOU REMOVE THE SAFETY GUARD, DON’T USE THESE ACCESSORIES.
We caution you not to force the accessories into the work piece.
Let the tool do the
work.
Use the correct accessories for your application.
Excessive force could cause
bearing failure in the head of the grinder.
The chain blades and carbide discs can be
used on their face, laterally and vertically to remove, shape, shave and etch wood.
A light motion works best.
– WARNING –
OVERHEATING
: Do not overwork the grinder.
If the unit overheats, switch it off and
allow it to cool. Failure to do so could burn out the motor. Also on a regular basis,
blow out the motor to prevent clogging which could contribute to overheating.
OVERTIGHTENING:
Do not over tighten accessories or you could strip the
internal gear in the lock down switch of the aluminum gear head.
Use a gentle
touch to secure the accessory – not brute force! In the event of failure, contact King
Arthur’s Tools. Look after your tool and your tool will look after you!

and 40° and move evenly back and
forth over the workpiece. Do not
bend the grinding disc into the
cutting surface during cutting work.
W A R N I N G !
Do not use the cutting disc for
roughening work. Risk of fracture!
Use the tungsten carbide or chain
saw accessories.

Always disconnect the power cord
from the power source before making
any adjustments or attaching any
accessories.
You may unexpectedly
cause the grinder to start, leading to
serious personal injury.
Accessories must be rated for at
least the speed recommended on the
tool warning label.
Wheels and other
accessories running over rated speed
can fl y apart and cause injury.
Do not reach in the area of the
rotating wheel.
The proximity of the
rotating wheel to your hand may not
always be obvious.
Carefully handle both the tool and
individual grinding wheels to avoid
chipping or cracking. Install a new
grinding wheel if tool is dropped
while grinding. Do not use a wheel
that may be damaged.
Fragments from
a wheel that bursts during operation
will fl y away at great velocity possibly
striking you or bystanders.
If a chain
tooth becomes jagged, simply
sharpen it with a few strokes of
the diamond fi le to bring the edge
back. Other accessories may need
replacing if damaged.
We highly recommend not to hold
a hoof in one hand while using the
grinder with chain saw in the other
hand. Use clamps to secure the hoof
whenever practical.
Clamping allows
you to use both hands to control the
tool.
If it is absolutely necessary to
hold the hoof or work object, allow
for suffi cient space between your
hand and the spinning blades/discs.
Use clamps to support workpiece
whenever practical. Never hold a
small workpiece in one hand and the
tool in the other hand while in use.
Allow for suffi cient space between
your hand and the spinning grinder.
Round material such as dowel rods,
pipes or tubing have a tendency to roll
while being cut, and may cause the
grinder to “bite” or jump toward you.
Clamping a small workpiece allows you
to use both hands to control the tool.
Inspect your hoof or workpiece
before cutting. When cutting
irregularly shaped objects, plan your
work so it will not slip, pinch the
grinder and be torn from your hand.
For example, if carving wood, make sure
there are no nails or foreign objects in
the workpiece. These alien materials
may cause the grinder to jump.
Never start the tool when the grinder
is engaged in the hoof or material.
The accessory’s cutting edge may grab
the cutting object causing loss of control
of the cutter and possible injury to the
animal.
Avoid bouncing and snagging the
accessories, especially when working
corners, sharp edges, etc.
This can
cause loss of control and kickback.
If the grinder becomes jammed or
bogged down in the hoof/workpiece,
turn the tool off by the switch. Wait
for the spinning accessory to stop
and unplug the tool, then work to
free the jammed material.
If the switch
is left on, the grinder could restart
unexpectedly causing serious injury.
Do not leave a running tool un-
attended; turn power off.
Only when
the accessory on the grinder comes to
a complete stop is it safe to put down.
Do not grind or sand near fl ammable
materials. Sparks from the wheel
could ignite these materials.
W A R N I N G !
Do not use the unit
on materials which contain asbestos.
Do not alter or misuse tool.
Any
alteration or modifi cation is a misuse
and may result in serious personal
injury.
This product is not intended
for use as a dental drill or in medical
applications.
Serious personal injury
may result.

SAVE THESE INSTRUCTIONS
GENERAL SAFETY RULES
Warning! Read and understand
all instructions.
Failure to follow all
instructions listed below may result
in electric shock, fi re and/or serious
personal injury.
Work Area
Keep your work area clean and well
lit.
Cluttered benches and dark areas
invite accidents.
Do not operate power tools in
explosive atmospheres, such as in
the presence of fl ammable liquids,
gases, or dust.
Power tools create
sparks which may ignite the dust
or fumes.
Keep bystanders, children, and
visitors away while operating a
power tool.
Distractions can cause
you to lose control.
Electrical Safety
Double Insulated tools are equipped
with a polarized plug (one blade is
wider than the other).
This plug will
fi t in a polarized outlet only one way. If
the plug does not fi t fully in the outlet,
reverse the plug. If it still does not fi t,
contact a qualifi ed electrician to install
a polarized outlet. Do not change the
plug in any way.
Double Insulation
eliminates the need for the three
wire grounded power cord and
grounded power supply system.
Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges, and refrigerators.
There is
an increased risk of electric shock if
your body is grounded.
Do not expose power tools to rain
or wet conditions.
Water entering
a power tool will increase the risk of
electric shock.
Do not abuse the cord. Never use
the cord to carry the tools or pull
the plug from an outlet. Keep cord
away from heat, oil, sharp edges
or moving parts. Replace damaged
cords immediately.
Damaged cords
increase the risk of electric shock.
When operating a power tool
outside, use an outdoor extension
cord marked “W-A” or “W”.
These
cords are rated for outdoor use and
reduce the risk of electric shock.
Personal Safety
Stay alert, watch what you are
doing and use common sense
when operating a power tool. Do
not use tool while tired or under
the infl uence of drugs, alcohol, or
medication.
A moment of inattention
while operating power tools may result
in serious personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long
hair. Keep your hair, clothing, and
gloves away from moving parts.
Loose clothes, jewelry, or long hair
can be caught in moving parts.
Avoid accidental starting. Be sure
switch is off before plugging in.
Carrying tools with your fi nger on the
switch or plugging in tools that have
the switch on invites accidents.
Remove adjusting keys or wrenches
before turning the tool on.
A wrench
or a key that is left attached to a
rotating part of the tool may result in
personal injury.
Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpected
situations.
Use safety equipment by always
wearing safety goggles or full-face
visor and dust mask.
Additionally,
non-skid safety shoes, hard hat, or
hearing protection must be used for
appropriate conditions. Using personal
safety devices and working in safe
environment reduces risk of injury. Use
the tool only in ventilated area.
Tool Use and Care
Use clamps, vise or other practical
ways to secure and support the
workpiece or hoof to a stable
platform.
Holding the object by hand
or against your body is unstable and
unsafe and may lead to loss of control.
Disconnect the plug from the
power source before making any
adjustments, changing accessories,
or storing the tool.
Such preventive
safety measures reduce the risk of
starting the tool accidentally.
Store idle tools out of reach of
children and other untrained
persons.
Tools are dangerous in
the hands of untrained users.
Maintain tools with care. Keep
cutting tools sharp and clean.
Properly maintained tools, with sharp
cutting edges, are less likely to bind
and are easier to control.
Check for misalignment or binding
of moving parts, breakage of
parts, and any other condition that
may affect the tools operation. If
damaged, have the tool serviced
before using.
Many accidents are
caused by poorly maintained tools.
Use only accessories that are
recommended by the manufacturer
for your model.
Accessories that may
be suitable for one tool may become
hazardous when used on another tool.
Service
Tool service must be performed
only by qualifi ed repair personnel.
Service or maintenance performed
by unqualifi ed personnel could result
in a risk of injury and could void the
warranty.
When servicing a tool, use only
identical replacement parts. Follow
instructions in the Maintenance
section of this manual.
Use of
unauthorized parts or failure to follow
Maintenance Instructions may create a
risk of electric shock or injury. Certain
cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc.
may damage plastic parts.
SPECIFIC SAFETY RULES
Be aware of the switch location,
when placing the tool down or
when picking the tool up.
You may
accidentally activate the switch.
After changing any accessory or
making any adjustments, make
sure the Allen key or any screws
are securely tightened
but not over
tightened.
tightened.
Hold the grinder by insulated
gripping surfaces when performing
an operation where the cutting tool
may contact hidden wiring or its
own cord.
Contact with a “live” wire
will make exposed metal parts of the
tool “live” and shock the operator. If
cutting into existing walls or other blind
areas where electrical wiring may exist
is unavoidable, disconnect all fuses or
circuit breakers feeding this worksite.
