HIKOKI G 18DBL, Handling Instructions Manual

toward or away from the operator, depending on direction of 

the wheel’s movement at the point of pinching.

Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect 

operating procedures or conditions and can be avoided by 

taking proper precautions as given below.

a) Maintain a 

fi

 rm grip on the power tool and position 

your body and arm to allow you to resist kickback 

forces. Always use auxiliary handle, if provided, for 

maximum control over kickback or torque reaction 

during start-up.

The operator can control torque reactions or kickback 

forces, if proper precautions are taken.

b)  Never place your hand near the rotating accessory.

Accessory may kickback over your hand.

c)  Do not position your body in the area where power 

tool will move if kickback occurs.

Kickback will propel the tool in direction opposite to the 

wheel’s movement at the point of snagging.

d) Use special care when working corners, sharp 

edges etc. Avoid bouncing and snagging the 

accessory.

Corners, sharp edges or bouncing have a tendency to 

snag the rotating accessory and cause loss of control or 

kickback.

e)  Do not attach a saw chain woodcarving blade or 

toothed saw blade.

Such blades create frequent kickback and loss of 

control.

SAFETY WARNINGS SPECIFIC FOR 

GRINDING AND ABRASIVE CUTTING-

OFF OPERATIONS

a)  Use only wheel types that are recommended for 

your power tool and the speci

fi

 c guard designed 

for the selected wheel. 

  Wheels for which the power tool was not designed 

cannot be adequately guarded and are unsafe.

b)  The grinding surface of centre depressed wheels 

must be mounted below the plane of the guard lip.

  An improperly mounted wheel that projects through the 

plane of the guard lip cannot be adequately protected.

c)  The guard must be securely attached to the power 

tool and positioned for maximum safety, so the 

least amount of wheel is exposed towards the 

operator.

  The guard helps to protect the operator from broken 

wheel fragments, accidental contact with wheel and 

sparks that could ignite clothing.

d) Wheels must be used only for recommended 

applications. For example: do not grind with the 

side of cut-o

ff

  wheel. 

 Abrasive 

cut-o

ff

  wheels are intended for peripheral 

grinding, side forces applied to these wheels may cause 

them to shatter.

e)  Always use undamaged wheel 

fl

 anges that are of 

correct size and shape for your selected wheel. 

 Proper 

wheel 

fl

 anges support the wheel thus reducing 

the possibility of wheel breakage. Flanges for cut-o

ff

wheels may be di

ff

 erent from grinding wheel 

fl

 anges. 

f)  Do not use worn down wheels from larger power 

tools. 

  Wheel intended for larger power tool is not suitable for 

the higher speed of a smaller tool and may burst.

ADDITIONAL SAFETY WARNINGS 

SPECIFIC FOR ABRASIVE CUTTING-

OFF OPERATIONS

a)  Do not “jam” the cut-o

ff

  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.

b)  Do not position your body in line with and behind 

the rotating wheel. 

  When the wheel, at the point of operation, is moving 

away from your body, the possible kickback may propel 

the spinning wheel and the power tool directly at you.

c)  When wheel is binding or when interrupting a cut 

for any reason, switch o

ff

  the power tool and hold 

the power tool motionless until the wheel comes to 

a complete stop. Never attempt to remove the cut-

o

ff

  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.

d)  Do not restart the cutting operation in the workpiece. 

Let the wheel reach full speed and carefully re-enter 

the cut. 

  The wheel may bind, walk up or kickback if the power 

tool is restarted in the workpiece.

e) Support panels or any oversized workpiece to 

minimize the risk of wheel pinching and kickback.

  Large workpieces tend to sag under their own weight. 

Supports must be placed under the workpiece near the 

line of cut and near the edge of the workpiece on both 

sides of the wheel.

f)  Use extra caution when making a “pocket cut” into 

existing walls or other blind areas.

  The protruding wheel may cut gas or water pipes, 

electrical wiring or objects that can cause kickback.

GENERAL SAFETY INSTRUCTIONS 

FOR CORDLESS DISC GRINDERS

–  Check that speed marked on the wheel is equal to or 

greater than the rated speed of the grinder;

–  Ensure that the wheel dimensions are compatible with 

the grinder;

–  Abrasive wheels shall be stored and handled with care in 

accordance with manufacturer’s instructions;

–  Inspect the grinding wheel before use, do not use 

chipped, cracked or otherwise defective products;

–  Ensure that mounted wheels and points are 

fi

 tted  in 

accordance with the manufacturer’s instructions;

–  Ensure that blotters are used when they are provided 

with the bonded abrasive product and when they are 

required;

–  Ensure that the abrasive product is correctly mounted 

and tightened before use and run the tool at no-load for 

30 seconds in a safe position, stop immediately if there 

is considerable vibration or if other defects are detected. 

If this condition occurs, check the machine to determine 

the cause;

–  If a guard is equipped with the tool never use the tool 

without such a guard;

–  When using an abrasive cutting wheel, be sure to remove 

the standard accessory wheel guard and attach the 

wheel guard with side guard (sold separately) (

Fig. 4

);

–  Do not use separate reducing bushings or adapters to 

adapt large hole abrasive wheels;

–  For tools intended to be 

fi

 tted with threaded hole wheel, 

ensure that the thread in the wheel is long enough to 

accept the spindle length;
