Optional Accessories; Maintenance - Makita TW0200 Instruction Manual

NOTE:
• When fastening screw M10 or smaller, carefully
adjust pressure on the switch so that the screw
is not damaged.
• Hold the tool pointed straight at the bolt or nut
without applying excessive pressure on the tool.
• If you fasten the bolt for a time longer than
shown in the figures, the bolt or the socket may
be overstressed, damaged, etc. Before starting
your job, always perform a test operation to
determine the proper fastening time for your
bolt. Especially for the bolt over than M10,
perform the above test operation to prevent the
trouble on socket or bolt, etc.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. Voltage
• Voltage drop will cause a reduction in the
fastening torque.
2. Socket
• Failure to use the correct size socket will
cause a reduction in the fastening torque.
• A worn socket (wear on the hex end or
square end) will cause a reduction in the
fastening torque.
3. Bolt
• Even though the torque coefficient and the
class of bolt are the same, the proper fasten-
ing torque will differ according to the diame-
ter of bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class
of bolt and the bolt length.
4. The use of the universal joint or the extension
bar somewhat reduces the fastening force of the
impact wrench. Compensate by fastening for a
longer period of time.
5. The manner of holding the tool or the material
of driving position to be fastened will affect the
torque.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
Never use gasoline, benzine, thinner,
NOTICE:
alcohol or the like. Discoloration, deformation or
cracks may result.
Replacing carbon brushes
► Fig.7: 1. Limit mark
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.
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.
