Maintenance; Optional Accessories - Makita DGA455 Instruction Manual

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 some European countries,
when using a diamond wheel, the ordinary guard can
be used. Follow the regulations in your country.)
• 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.
Operation with wire cup brush (optional
accessory)
CAUTION:
• Check operation of brush by running tool with no load,
insuring that no one is in front of or in line with brush.
• Do not use brush that is damaged, or which is out of
balance. Use of damaged brush could increase
potential for injury from contact with broken brush
wires.
Remove the battery cartridge from the tool and place it
upside down allowing easy access to spindle. Remove
any accessories on spindle. Thread wire cup brush onto
spindle and tighten with supplied wrench. When using
brush, avoid applying too much pressure which causes
over bending of wires, leading to premature breakage.

Operation with wire wheel brush (optional
accessory)
CAUTION:
• Check operation of wire wheel brush by running tool
with no load, insuring that no one is in front of or in line
with the wire wheel brush.
• Do not use wire wheel brush that is damaged, or which
is out of balance. Use of damaged wire wheel brush
could increase potential for injury from contact with
broken wires.
• ALWAYS use guard with wire wheel brushes, assuring
diameter of wheel fits inside guard. Wheel can shatter
during use and guard helps to reduce chances of
personal injury.
Remove the battery cartridge from the tool and place it
upside down allowing easy access to spindle. Remove
any accessories on spindle. Thread wire wheel brush onto
spindle and tighten with the wrenches. (Fig. 22)

When using wire wheel brush, avoid applying too much
pressure which causes over bending of wires, leading to
premature breakage.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and the
battery 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.
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. 23)
Remove the dust cover from inhalation vent and clean it
for smooth air circulation. (Fig. 24)
NOTE:
• Clean out the dust cover when it is clogged with dust or
foreign matters. Continuing operation with a clogged
dust cover may damage the tool.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
