Ec Declaration Of Conformity; Maintenance - Makita 6953 Instruction Manual

Operation
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in Fig. 6 for standard
bolt or Fig. 7 for high tensile bolt. Hold the tool firmly and
place the socket over the bolt or nut. Turn the tool on and
fasten for the proper fastening time.
NOTE:
• When fastening screw M8 or smaller, carefully adjust
pressure on the switch trigger 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 other than M8, per-
form the above test operation to prevent the trouble on
socket or bolt, etc.
The fastening torque is affected by a wide variety of fac-
tors including the following. After fastening, always check
the torque with a torque wrench.
1. 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.
2. Bolt
• Even though the torque coefficient and the class of
bolt are the same, the proper fastening torque will
differ according to the diameter of the 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.
3. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.
4. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
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)
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. 9)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centres,
always using Makita replacement parts.
