Lubrication
1. The machine is equipped with 2RS-type ball bearings (with double rubber seals). They are therefore
dust-tight, which means that they can get slightly warmer than conventional ball bearings. This is
however not a problem.
2. To ensure proper operation of the machine and to inhibit rust formation and thus moving parts from
getting jammed, the following parts must be lubricated regularly:
- the axes of the planing and thicknessing tables;
- the drill table screw and sliding surfaces for crosswise, longitudinal and vertical travels;
- the chains of the drive system (to reach them, remove the protective plate in which the electrical
control panel is mounted).
Use SAE 30 type oil for lubrication. Chains should be lubricated at least once a year. All other parts
should be lubricated once a month.
Note: When working with wet wood, the machine must be very well lubricated and maintained.
Problems
Causes and solutions
1 The machine does not start after pressing the start button:
- The switch is incorrectly positioned: check and move it to the correct position.
2 The main fuse is blown:
– Motor overload due to dull tools, excessive chip removal or to the fact that wood was pushed
through the tool too fast: sharpen the tool, reduce chip removal, slow down slightly.
– Blocked component: check and clear.
– Lack of power and/or power failure: check the electrical installation.
– Defective fuses: replace the fuses.
3 Speed decrease during operation:
– Belt tension: Tighten the belt. - Blunt tools: Grinding.
4 Vibrations with the tools installed:
– Unbalanced blade: balance the blade.
5 The planer shaft does not turn in the right direction (3 phase machine):
– Incorrect electrical connection: reverse 2 of the 3 feed wires (see Section "Electrical
connection").
Please contact your dealer if you cannot solve the problem yourself or if the problem is not listed
above.
