ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Installing or removing wheel point (Fig. 5 & 6)
Loosen the collet nut and insert the wheel point into the
collet nut. Use one wrench to hold the spindle and the
other one to tighten the collet nut securely.
The wheel point should not be mounted more than 8 mm
from the collet nut. Exceeding this distance could cause
vibration or a broken shaft.
To remove the wheel point, follow the installation proce-
dure in reverse.
CAUTION:
• Use the correct size collet cone for the wheel point
which you intend to use.
OPERATION (Fig. 7)
Turn the tool on without the wheel point making any con-
tact with the workpiece and wait until the wheel point
attains full speed. Then apply the wheel point to the
workpiece gently. To obtain a good finish, move the tool
in the leftward direction slowly.
CAUTION:
• Apply light pressure on the tool. Excessive pressure on
the tool will only cause a poor finish and overloading of
the motor.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before attempting to perform
inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes. (Fig. 8)
Insert the top end of slotted bit screwdriver into the notch
in the tool and remove the holder cap cover by lifting it
up. (Fig. 9)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 10)
Reinstall the holder cap cover on the tool.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
OPTIONAL ACCESSORIES
CAUTION:
• These accessories or attachments are recommended

tor, insert the side handle on the tool barrel as far as it
will go and rotate it to the desired angle. Then tighten the
handle firmly by turning clockwise.
CAUTION:
• When using the tool without handle, always install the
rubber protector on the tool.
• When installing the rubber protector, always push it
onto the tool so that the top round recessed shape of
the rubber is positioned near the switch position.

• Some items in the list may be included in the tool pack-
age as standard accessories. They may differ from
country to country.
Noise
The typical A-weighted noise level determined according
to EN60745:
Sound pressure level (L
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
Wear ear protection
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN60745:
Model BGD800
Work mode: surface grinding
Vibration emission (a
Uncertainty (K): 1.5 m/s
Model BGD801
Work mode: surface grinding
Vibration emission (a
Uncertainty (K): 1.5 m/s
• The declared vibration emission value has been mea-
sured 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.
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 oper-
ator 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).
