Dressing diamond wheel
If the cutting action of the diamond wheel begins to
diminish, use an old discarded coarse grit bench grinder
wheel or concrete block to dress the diamond wheel. To
do this, tightly secure the bench grinder wheel or con-
crete block and cut in it.
After use
Blow away dust from the inside of the tool by running the
tool at an idle for a while. Brush off accumulation of dust
on the base. Accumulation of dust in the motor or on the
base may cause a malfunction of the tool.
Cleaning covers (Fig. 12 & 13)
When accumulation of dust on the cover (A) looks exces-
sive, loosen the clamp and remove the cover (A). Wash
off accumulation of dust inside the cover (A) and wipe it.
Then install the cover (A) on the tool so that its side with
“Upside
” mark faces upward. Push the cover (A)
toward the motor as far as it will go and secure it by tight-
ening the clamp.
When changing the wheel, clean the cover (B) at the
same time. Loosen the screw securing the cover (B) and
remove the cover (B). Wash off accumulation of dust
inside the cover (B) and wipe it. Then attach the cover (B)
to the tool by tightening the screw. Accumulation of dust
inside the covers may cause a malfunction of the tool.
CAUTION:
• When using the tool, be sure to attach the covers (A)
and (B).
Replacing carbon brushes (Fig. 14 & 15)
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.
First, remove the cover (A).
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.
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.

• 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).
