Maintenance; Replacing Carbon Brushes - Makita LC1230 Instruction Manual

CAUTION:
Do NOT cut the workpiece as shown in the Fig. C
•
since this may cause it to be ejected from the vise,
possibly resulting in injury.
The saw blade is subjected to greater wear when the
area A in the Fig. B is cut. Place a wooden block up
against the workpiece as shown in the Fig. D so that the
saw blade will enter area A at an angle. This will help to
extend the saw blade life.
The allowable cutting dimensions are reduced when a
wooden block is used. Use a wooden block whose
dimensions are equivalent to the maximum allowable
cutting dimensions minus the dimensions of the
workpiece to be cut. This will further minimize the
shortening of the saw blade life.

The saw blade is subjected to greater wear when the
areas A and B in figure F and figure G are cut. Place a
wooden block up against the workpiece as shown in
figure H and figure I so that the saw blade will enter
areas A and B at an angle. This will help to minimize the
shortening of the saw blade life.
The allowable cutting dimensions are reduced when a
wooden block is used. Use a wooden block whose
dimensions are equivalent to the maximum allowable
cutting dimensions minus the dimensions of the
workpiece to be cut. This will further minimize the
shortening of the saw blade life.

Secure the workpiece in the vise as shown in figure J,
and proceed to cut it.
CAUTION:
Do NOT cut the workpiece as shown in figure K
•
since this may cause it to be ejected from the vise,
possibly resulting in injury.

Carrying tool
CAUTION:
B
The chain for transportation shall be adjusted to
•
minimize the accessible zone of the saw blade
before transporting the tool.
Fig.13
Fold down the tool head to the position where you can
attach the chain to the hook on the handle. Grasp the
carrying grip when carrying the tool.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
Replacing saw blade
Continuing to use a dull and worn blade may cause
motor overload and decreased cutting efficiency.
Replace with a new blade as soon as it is no longer
effective.

Replacing carbon brushes

Fig.14
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.
