WARNING: Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury.
• Save all warnings and instructions for future reference.
• The term "power tool" in the warnings refers to your mains-operated (corded) power
tool or battery-operated (cordless) power tool.
Work area safety
• Ensure your work area is clean and well lit. Cluttered or dark areas invite accidents.
• 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.
• Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
Electrical safety
• This power tool plugs must match the power outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
• 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.
• 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 power 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.
• 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.
• If operating a power tool in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
SAFETY & WARNINGS

Personal safety
• 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 distraction while operating power tools
may result in serious personal injury.

control of the power tool in unexpected situations.
• Do not wear loose clothing or jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce
dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe
injury within a fraction of a second.
Power tool use and care
• Always 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.
• 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.
• Disconnect the plug from the power source and/or remove the battery pack, if
detachable, 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.

unfamiliar with the power tool or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or seizing of moving
parts, breakage of parts and any other condition that may affect the power tool’s
operation. Many accidents are caused by poorly maintained power tools. If
damaged, cease use immediately and contact Kogan.com for support.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to seize and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these
instructions, 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.
• Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and control
of the tool in unexpected situations.

• If the replacement of the supply cord is necessary, please contact Kogan.com for
support.
Safety instructions for cut-off machines
Cut-off machine safety warnings
• Position yourself and bystanders away from the plane of the rotating wheel. The
guard helps to protect the operator from broken wheel fragments and accidental
contact with wheel.
• Use only bonded reinforced cut-off wheels for your power tool. Just because an
accessory can be attached to your power tool, it does not assure safe operation.
• The rated speed of the accessory must be at least equal to the maximum speed
marked on the power tool. Accessories running faster than their rated speed can
break and fly apart.
• Wheels must be used only for recommended applications. For example: do not
grind with the side of a cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of correct diameter for your
selected wheel. Proper wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
• The outside diameter and the thickness of your accessory must be within the
capacity rating of your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
• The arbour size of wheels and flanges must properly fit the spindle of the power
tool. Wheels and flanges with arbour holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate excessively and may
cause loss of control.
• Do not use damaged wheels. Before each use, inspect the wheels for chips and
cracks. If the power tool or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the wheel, position yourself and
bystanders away from the plane of the rotating wheel and run the power tool at
maximum no load speed for one minute. Damaged wheels will normally break
apart during this test time.

• Wear personal protective equipment. Depending on application, use face shield,
safety goggles or safety glasses. As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of stopping flying debris generated
by various operations. The dust mask or respirator must be capable of filtrating
particles generated by your operation. Prolonged exposure to high intensity noise
may cause hearing loss.
• Keep bystanders a safe distance away from work area. Anyone entering the work
area must wear personal protective equipment. Fragments of workpiece or of a
broken wheel may fly away and cause injury beyond immediate area of operation.
• Position the cord clear of the spinning accessory. If you lose control, the cord may
be cut or snagged and your hand or arm may be pulled into the spinning wheel.
• Regularly clean the power tool’s air vents. The motor’s fan can draw the dust inside
the housing and excessive accumulation of powdered metal may cause electrical
hazards.
• Do not operate the power tool near flammable materials. Do not operate the power
tool while placed on a combustible surface such as wood. Sparks could ignite
these materials.
• Do not use accessories that require liquid coolants. Using water or other liquid
coolants may result in electrocution or shock.
• Operate the grinder within its indicated design specification. Your grinder has a
plate indicating:
1. Size of arbour.
2. No-load speed in revolutions per minute.
3. Proper grinding wheel.
• Keep work area clean. Cluttered areas and benches are safety hazards. Ensure
that the working area of the grinding wheel is free of tools or other objects before
starting up the grinder. Frequently clean grinding dust from beneath the grinder.
• Do not use power tools in damp or wet environments or expose them to rain. Be
sure to keep the work area well lighted.
• Check the position of the power cord during operation making sure that it remains
outside the range of action of the grinding wheel and is not under tension. Never
operate in the vicinity of other electrical cables/cords.
• Ensure the workshop is child proof with padlocks and master switches. Also, do not
allow anyone but the operator to touch the power cord or remain in the close
vicinity of the grinder while operating.
Note:
The power supply cable/cord comes complete with terminals and circuit protection.
Connecting the power supply cable/cord terminals directly into the switch
completes the electrical system for the grinder. The final electrical connection to the
outlet should be made in such a way as to prevent damage by individuals or
passing vehicles that could endanger both them and the operator.

• Before starting the grinder, ensure that the grinding wheel is correctly secured and
positioned in the up, rest position. Do not over-tighten the wheel mounting flange
nut.
• Use the vice to hold the chain. It frees both hands for moving the grind head/wheel
down to grind the chain.
• Never stand on an unstable platform.
• Always work in a stable and safe position. Serious injury could occur if the grinder is
tipped or if the cutting tool is unintentionally contacted.
• Maintain tools with care. Keep tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories.
WARNING: The grinder must be used only in a place that is protected from
dust and dampness, that is well-lit, out of the reach of children and away
from gases or other flammable or explosive liquids.
