OPERATION MANUAL
The thicknesser is supplied with bearings that are lubricated and sealed at the factory. These
bearing do not require any further attention unless they need to be replaced. If a bearing fails,
the thicknesser will probably develop a noticeable rumble or vibration, which will increase
when the machine is under load. The bearings are standard sizes and can be replaced.
MAIN BEARINGS
MOTOR BRUSH REPLACEMENT
Brush life will vary depending on the load placed on the
motor. The brushes should be inspected every 10-15
hours of use.
To inspect:
1. DISCONNECT MACHINE FROM THE POWER SUPPLY
2. Remove the Brush Holders, one of which is shown at (A).
The other is located in the same position on the rear
of the motor assembly. The Brush Holder can be
removed using a flat blade screwdriver. (Fig. 5.4)
3. Once the brush has been removed, inspect the carbon
(B), the spring (C), and the wire (D).
4. If the carbon of either brush is worn down to 4.5mm or
less, both brushes should be replaced. Also if the spring
or wire are burned or damaged in any way, both
brushes should be replaced. (Fig.5.6)
NOTE: Contact your distributor for replacement brushes
