WARNING
 Fuel is highly flammable and its fumes should not be 
inhaled. Be particularly careful when handling the 
machine as the sparks produced when cutting metal can 
easily ignite any fuel spillage.
Cutting safety
○Keep bystanders at a safe distance, away from the 
work area. Anyone entering the work area must wear 
personal protective equipment. Flying fragments from 
the workpiece or the cut-offwheel may cause injury.
 Children, other unauthorized persons and animals must 
remain well away from the work area.
○Hold the machine firmly with the right hand on the rear 
handle and the left hand on the front handle.
○Keep firm footing and balance. Do not over-reach.
○Keep all parts of your body away from the muffler and 
cutting attachment when the engine is running.
○Make sure to check the work area for any hidden 
hazards such as water or gas pipes, electrical cables 
and flammable substances.
○Never place the machine on the ground when running.
○Always ensure that the engine is shut offand any cutting 
attachments have completely stopped before clearing 
debris from the cutting attachment.
○Always carry a first-aid kit when operating any power 
equipment.
○The muffler gets very hot during and after use. This also 
applies during idling.
 Be aware of the fire hazard, especially when working 
near flammable substances and/or vapours.
WARNING
○Exhaust gases from the engine are hot and may contain 
sparks which can cause a fire. 
 Also, sparks are generated when cutting metal with this 
machine.
 Never use the machine where flammable substances 
and gases are present.
○Sparks generated from cutting operations can cause 
fires. Always have adequate fire extinguishing equipment 
available.
○When relocating to a new work area, be sure to shut off
the machine and ensure that all cutting attachments are 
stopped.
○Always ensure that the engine is shut offand any cutting 
attachments have completely stopped before moving.
 Gyroscopic forces occur when moving while the engine 
is operating and the cut-offwheel is rotating. This may 
cause you to lose control of the machine.
○Never cut materials that consist of asbestos. 
○Never leave the engine running while unattended 
(e.g. on the ground).
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged 
rotating wheel. Pinching or snagging causes sudden stalling 
of the rotating wheel which in turn causes the machine to 
be forced in the direction opposite of the wheel's rotation at 
the point of the binding. For example, if an abrasive wheel is 
snagged or pinched by the workpiece, the edge of the wheel 
that is entering into the pinch point can dig into the surface of 
the material causing the wheel to climb out or kick out. The 
wheel may either jump toward or away from the operator, 
depending on the direction of the wheel's movement at the 
point of pinching. Abrasive wheels may also break under 
these conditions. 
Either of these reactions may cause you to lose control of the 
machine which could result in serious personal injury.
Kickback is the result of cut-offmachine misuse and/or 
incorrect operating procedures or conditions that can be 
avoided by taking proper precautions as given below.
○Kickback occurs when the upper angle of the cut-off
wheel is used or touches an object when the cut-off
wheel is running. Pay special attention not to touch the 
upper angle of the cut-offwheel to any object. (Fig. 2, 
Fig. 3)
○Use special care when working corners, sharp edges 
etc. Avoid bouncing and snagging the cut-offwheel.
 Corners, sharp edges or bouncing have a tendency to 
snag the rotating wheel and cause loss of control or 
kickback. (Fig. 4)
○Do not use cut-offwheels other than those approved or 
recommended by the manufacturer. Never use blades 
designed for cutting wood. Failure to comply could result 
in personal accidents or injury.
○Do not jam the wheel or apply excessive pressure. Do 
not attempt to make an excessive depth of cut.
 Overstressing the wheel increases the loading and 
susceptibility to twisting or binding of the wheel in the cut 
and the possibility of kickback or wheel breakage.
○If the wheel binds or a cut is interrupted for any reason, 
stop the engine and hold the machine motionless until 
the wheel comes to a complete stop. Never attempt 
to remove the wheel from the cut while the wheel is in 
motion otherwise kickback may occur. Investigate and 
take corrective action to eliminate the cause of wheel 
binding.
○Do not restart the cutting operation with the wheel in the 
workpiece. After allowing the wheel to reach full speed, 
carefully re-enter the cut. The wheel may bind, walk up or 
kickback if the power tool is restarted in the workpiece.
○Provide supports for panels or any oversized workpiece 
to minimize risk of wheel pinching and kickback.
 Large workpieces tend to sag under their own weight. 
Supports must be placed under the workpiece so that 
the cutting surface to open. (Fig. 5)
Maintenance safety
○Maintain the machine according to recommended 
procedures.
○Disconnect the spark plug before performing 
maintenance except for carburetor adjustments.
○Keep others away when making carburetor adjustments.
○Use only genuine HiKOKI replacement parts as 
recommended by the manufacturer.
CAUTION
 Do not disassemble the recoil starter. There is a 
possibility of personal injury with recoil spring.
WARNING
 Improper maintenance could result in serious engine 
damage or in serious personal injury.
Transport and storage
○Carry the machine by hand with the engine stopped and 
the muffler away from your body.
○Allow the engine to cool, empty the fuel tank and 
carburetor, and secure the machine before storing or 
transporting.
○Store machine out of the reach of children.
○Clean and maintain the machine carefully and store it in 
a dry place.
○Make sure stop switch is offwhen transporting or storing.
○Do not store the cut-offwheels in a wet or frost condition. 
Pay special attention about the abrasive wheel.
 There is a risk of bursting to using the abrasive wheel 
wetted.
If situations occur which are not covered in this manual, take 
care and use common sense. Contact HiKOKI Authorized 
Service Centers if you need assistance.
