CAUTION:
• Always assure that the bit is securely retained by
attempting to pull the bit out of the tool holder after
completing the above procedure.
• The bit without a collar cannot be retained by the method
shown in Fig.(1).
To remove the bit, follow the installation procedure in
reverse.
OPERATION
Chipping/Scaling/Demolition
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the tool
will not increase the efficiency.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically shut
off the motor. When this occurs, both carbon brushes should
be replaced. 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 holder cap plates.
