off by use, the wheel may be worked in both A and B
direction. (Fig. 9)
Operation with abrasive cut-off/diamond
wheel (optional accessory) (Fig. 10)
The direction for mounting the lock nut and the inner
flange varies by wheel thickness.
Refer to the table below. (Fig. 11)
WARNING:
• When using an abrasive cut-off/diamond wheel, be
sure to use only the special wheel guard designed for
use with cut-off wheels. (In European countries, when
using a diamond wheel, the ordinary guard can be
used.)
• NEVER use cut-off wheel for side grinding.
• 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, wheel breakage and
overheating of the motor may occur.
• Do not start the cutting operation in the workpiece. Let
the wheel reach full speed and carefully enter into the
cut moving the tool forward over the workpiece surface.
The wheel may bind, walk up or kickback if the power
tool is started in the workpiece.
• During cutting operations, never change the angle of
the wheel. Placing side pressure on the cut-off wheel
(as in grinding) will cause the wheel to crack and break,
causing serious personal injury.
• A diamond wheel shall be operated perpendicular to
the material being cut.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the vents
start to become obstructed. (Fig. 12)
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.

Noise
The typical A-weighted noise level determined according
to EN60745:
Sound pressure level (L
Sound power level (L
Uncertainty (K): 3 dB (A)
Wear ear protection.
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN60745:
Model GA4030
Work mode: surface grinding
Vibration emission (a
Uncertainty (K): 1.5 m/s
Model GA4530
Work mode: surface grinding
Vibration emission (a
Uncertainty (K): 1.5 m/s
Model GA5030
Work mode: surface grinding
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration emission value has been
measured in accordance with the standard test method
and may be used for comparing one tool with another.
• The declared vibration emission value may also be
used in a preliminary assessment of exposure.
• The declared vibration emission value is used for main
applications of the power tool. However if the power
tool is used for other applications, the vibration
emission value may be different.
WARNING:
• The vibration emission during actual use of the power
tool can differ from the declared emission value
depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of exposure in
the actual conditions of use (taking account of all parts
of the operating cycle such as the times when the tool
is switched off and when it is running idle in addition to
the trigger time).
