Makita GA007G, Instruction Manual

7 ENGLISH

4. 

Wheels must be used only for recommended 

applications. For example: do not grind with the 

side of cut-off wheel.

 Abrasive cut-off wheels are 

intended for peripheral grinding, side forces applied 

to these wheels may cause them to shatter.

5. 

Always use undamaged wheel flanges that are 

of correct size and shape for your selected 

wheel.

 Proper wheel flanges support the wheel 

thus reducing the possibility of wheel breakage. 

Flanges for cut-off wheels may be different from 

grinding wheel flanges.

6. 

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:

1. 

Do not “jam“ the cut-off wheel or apply exces

-

sive 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 possibil-

ity of kickback or wheel breakage.

2. 

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 spin-

ning wheel and the power tool directly at you.

3. 

When wheel is binding or when interrupting 

a cut for any reason, switch off the power 

tool and hold the power tool motionless until 

the wheel comes to a complete stop. Never 

attempt to remove the cut-off wheel from the 

cut while the wheel is in motion otherwise 

kickback may occur.

 Investigate and take correc-

tive action to eliminate the cause of wheel binding.

4. 

Do not restart the cutting operation in the work-

piece. 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.

5. 

Support panels or any oversized workpiece to 

minimize the risk of wheel pinching and kick-

back.

 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.

6. 

Use extra caution when making a “pocket cut” 

into existing walls or other blind areas.

 The 

protruding wheel may cut gas or water pipes, elec-

trical wiring or objects that can cause kickback.

Safety Warnings Specific for Sanding Operations:

1. 

Do not use excessively oversized sanding 

disc paper. Follow manufacturers recommen-

dations, when selecting sanding paper.

 Larger 

sanding paper extending beyond the sanding 

pad presents a laceration hazard and may cause 

snagging, tearing of the disc or kickback.

Safety Warnings Specific for Wire Brushing 

Operations:

1. 

Be aware that wire bristles are thrown by the 

brush even during ordinary operation. Do not 

overstress the wires by applying excessive 

load to the brush.

 The wire bristles can easily 

penetrate light clothing and/or skin.

2. 

If the use of a guard is recommended for wire 

brushing, do not allow any interference of the 

wire wheel or brush with the guard.

 Wire wheel 

or brush may expand in diameter due to work load 

and centrifugal forces.

Additional Safety Warnings:

1. 

When using depressed centre grinding wheels, 

be sure to use only fiberglass-reinforced wheels.

2. 

NEVER USE Stone Cup type wheels with this 

grinder.

 This grinder is not designed for these 

types of wheels and the use of such a product 

may result in serious personal injury.

3. 

Be careful not to damage the spindle, the flange (espe

-

cially the installing surface) or the lock nut. Damage to 

these parts could result in wheel breakage.

4. 

Make sure the wheel is not contacting the 

workpiece before the switch is turned on.

5. 

Before using the tool on an actual workpiece, 

let it run for a while. Watch for vibration or 

wobbling that could indicate poor installation 

or a poorly balanced wheel.

6. 

Use the specified surface of the wheel to per

-

form the grinding.

7. 

Do not leave the tool running. Operate the tool 

only when hand-held.

8. 

Do not touch the workpiece immediately after 

operation; it may be extremely hot and could 

burn your skin.

9. 

Observe the instructions of the manufacturer 

for correct mounting and use of wheels. 

Handle and store wheels with care.

10. 

Do not use separate reducing bushings or 

adaptors to adapt large hole abrasive wheels.

11. 

Use only flanges specified for this tool.

12. 

For tools intended to be fitted with threaded 

hole wheel, ensure that the thread in the wheel 

is long enough to accept the spindle length.

13. 

Check that the workpiece is properly supported.

14. 

Pay attention that the wheel continues to 

rotate after the tool is switched off.

15. 

If working place is extremely hot and humid, 

or badly polluted by conductive dust, use a 

short-circuit breaker (30 mA) to assure opera-

tor safety.

16. 

Do not use the tool on any materials contain-

ing asbestos.

17. 

When use cut-off wheel, always work with 

the dust collecting wheel guard required by 

domestic regulation.

18. 

Cutting discs must not be subjected to any 

lateral pressure.

19. 

Do not use cloth work gloves during operation.

Fibers from cloth gloves may enter the tool, which 

causes tool breakage.

SAVE THESE INSTRUCTIONS.
