SECTION 6: OPERATIONS
Test Run
! | Disconnect power to the | |||
machine when perform- | ||||
ing | any | maintenance, | ||
| assembly | or | adjust- | |
| ments. Failure to do this | |||
| may | result in | serious | |
| personal injury. |
| ||
Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back.
Wear safety glasses during the entire opera- tion process. Failure to comply may result in serious personal injury.
Once assembly is complete and adjustments are done to your satisfaction, you are ready to test run the machine.
Turn on the power supply at the main panel. Press the START button. Make sure that your fin- ger is poised on the STOP button, just in case there’s a problem. The jointer should run smooth- ly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigat- ed and corrected before operating the machine further.
If you cannot easily locate the source of an unusual noise or vibration, contact our service department for help.
Stock Inspection
If the stock has large or loose knots, consider finding another workpiece. Knots in a workpiece can be dangerous to the operator, as well as destructive to equipment.
When jointing, always cut with the grain rather than against it. Cutting against the grain (going against the pattern of the wood’s growth rings) chips the wood instead of cutting it, making the workpiece rough and irregular. Look at the side of your board. If the direction of the grain structure facing the cutterhead runs toward the cutterhead as it sits on the infeed table, your cut will be with the grain as shown in Figure 18.
Occasionally, you will find woods that defy all rules. In those rare cases, it is best to feed the workpiece slowly and take several shallow cuts. A few extra passes will hurt much less than a ruined workpiece.
