INSPECTION AND REPLACEMENT OF MOTOR BUSHES
WARNING:
before inspecting the brushes disconnect the feeder cable.
Brushes' duration is variable. It depends on the
amount of work done by the motor. Verify the
brushes after the first 20 hours of use of a new
machine or after mounting new brushes.
After the first check, inspect them every 10 hours of
work, until the replacement becomes necessary.
The brush-sockets Fig.18 are located inside the
motor carter. Replace each brush when the carbon
left is less than 5mm, or whenever a spring or a wire
are burned or damaged. If the brushes are found
usable at the inspection, remount them in the same
position they were before.
Proceed as follows:
1. Open and unscrew the two screws fixing the
motor carter.
2. remove the carter and then the brushes (B) fig.18. Press the spring (A) to release the brushes, disconnect
the cable (C).
3. take off each brush (B) check it and replace it if necessary. Replace both brushes also if only one is worn
out.
Note : After controlling the brushes, if you do not replace them, make sure to reposition them in the same
position as before.
1. Position the brushes in the motor. Re-position the spring (A)
2. Run the machine for about 5 - 10 minutes to allow the brushes to adapt to their position. If these are not
correctly assembled the motor can be seriously damaged. While the brushes adapt to their position you
can notice sparks coming out of the motor: this is normal for new brushes
WARNING: When using power tools, always refer to the basic safety rules, fundamental to
prevent fire, electric shock and injuries. Also read carefully before using the machine and keep
them for the entire life of the machine.
DISK BLADE REPLACEMENT
Immediately replace the blade disk if worn-out or bad cutting. The bevelled or worn-out blades can cause
serious injuries to the user and make your machine loosing precision
WARNING!
- Before changing the blade disk, disconnect the feeder cable. The feeder cable must remain
disconnected for every repair or maintenance.
- to prevent injuries from ejection of chips, do not use blade diameter bigger or smaller than 305
mm.
- do not use bevelled blades: it could be dangerous.
- only use cross-cut blades. If you use carbide inserted blades, make sure their toothing angle is
neutral or negative
Do not use deep toothed blades: these could flex and touch the disk protection
