Operation Safety

Your safety is important! Please follow the warnings below during this entire section:

To avoid serious personal injury, read and become familiar with the entire instruction manual before using the jointer.

Damage to your eyes, lungs, and ears could result from failure to wear safety glasses, a dust mask, and hearing protec- tion while using with this machine.

Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing rolled up and long hair tied up and away from machinery.

Stock Inspection & Requirements

Here are some rules to follow when choosing and cutting stock:

•DO NOT joint or surface plane stock that contains knots. Injury to the operator or damage to the workpiece can occur if the knots become dislodged during the cutting operation.

•DO NOT joint or surface plane “against” the grain direction. Cutting “against” the grain increases the likelihood of stock kick- back (See Warning #13 on page 4), as well as tear-out on the workpiece.

•Jointing and surface planing “with” the grain produces a better finish and is safer for the operator. Cutting “with” the grain is best described as feeding the stock on the jointer so the grain points down and toward you as viewed on the edge of the stock (Figure 27). Note—If the grain changes direction along the edge of the board, your best bet for improving cut quality is to decrease the cutting depth and make addi- tional passes.
