○ Keep others away when making carburetor adjustments. ○ Use only accessories as recommended for this machine

by the manufacturer.

○ Select and mount the correct cut-oﬀ wheel for the type of

work to be carried out.

○ All items, other than the items listed in the operator’s/

owner’s manual, should be performed by HiKOKI Authorized Service Centers. (For example, if improper tools are used to remove the ﬂ ywheel or if an improper tool is used to hold the ﬂ ywheel in order to remove the clutch, structural damage to the ﬂ ywheel could occur and could subsequently cause the ﬂ ywheel to burst.)

WARNING

○ Never modify the machine in any way. Do not use your

machine for any job except that for which it is intended.

○ Never use wheels that are rated for speeds lower than

the maximum spindle speed indicated on the machine.

A wheel running faster than its rated speed can break

and ﬂ y apart.

○ The arbor size of wheels and ﬂ anges must properly ﬁ t

the spindle of the machine.

Wheels and ﬂ anges with arbor holes that do not match

the mounting hardware of the machine will run oﬀ - balance, vibrate excessively and may cause loss of control.

○ It is important to use only cut-oﬀ wheels designed for use

on hand-held cut-oﬀ machines. It is dangerous to use a cut-oﬀ wheel that is not intended for a hand-held cut-oﬀ machine.

Fuel safety

○ Mix and pour fuel outdoors and where there are no

sparks or ﬂ ames.

○ Use a container approved for fuel. ○ Wipe oﬀ all fuel spills and allow any remaining fuel to

evaporate before starting engine.

○ Move at least 3 m away from fueling site before starting

engine.

○ Stop engine and let it cool for a few minutes before

opening fuel tank cap.

○ Store the machine and fuel in area where fuel vapors

cannot reach sparks or open ﬂ ames from water heaters, electric motors or switches, furnaces, etc.

WARNING

Fuel is highly ﬂ ammable 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-oﬀ wheel may cause injury. Children, other unauthorized persons and animals must

remain well away from the work area. ○ Hold the machine ﬁ rmly with the right hand on the rear

handle and the left hand on the front handle.

○ Keep ﬁ rm footing and balance. Do not over-reach. ○ Keep all parts of your body away from the muﬄ er 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 ﬂ ammable substances.

○ Never place the machine on the ground when running. ○ Always ensure that the engine is shut oﬀ and any cutting

attachments have completely stopped before clearing

debris from the cutting attachment. ○ Always carry a ﬁ rst-aid kit when operating any power

equipment. ○ The muﬄ er gets very hot during and after use. This also

applies during idling. Be aware of the ﬁ re hazard, especially when working

near ﬂ ammable substances and/or vapours.

WARNING

○ Exhaust gases from the engine are hot and may contain

sparks which can cause a ﬁ re. Also, sparks are generated when cutting metal with this

machine. Never use the machine where ﬂ ammable substances

and gases are present. ○ Sparks generated from cutting operations can cause

ﬁ res. Always have adequate ﬁ re 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 oﬀ and any cutting

attachments have completely stopped before moving. Gyroscopic forces occur when moving while the engine

is operating and the cut-oﬀ wheel 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-oﬀ machine misuse and/or incorrect operating procedures or conditions that can be avoided by taking proper precautions as given below.

English

○ 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-oﬀ wheel to any object. (Fig. 2, Fig. 3)

○ Use special care when working corners, sharp edges

etc. Avoid bouncing and snagging the cut-oﬀ wheel.

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-oﬀ wheels 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 muﬄ er 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 oﬀ when transporting or storing. ○ Do not store the cut-oﬀ wheels 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.
