SECTION 1: SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substi- tute for proper accident prevention measures.

7. Place the round table insert in the table top and replace the tapered pin so it fits snugly in the hole on the side of the table. Do not use excessive force. The tapered table pin should always be in position when operating the bandsaw. Operating without the pin can allow a step in the table top which can catch your work- piece during cutting. Serious personal injury may occur if this caution is ignored. Figure 3. Trunnion support in correct position. 3. Before you place the table on the trun

Rails and Fence When installing the fence, notice that the front and back edges of the table have two threaded holes. These holes accept the round spacers and socket head cap screws that attach the fence rails to the table. To install the rails and fence: 1. Place the two spacers in the table, similar to Figure 6. Figure 8. Rail and fence assembly. 4. Slide the back rail into the fence rear lock and secure the rail to the back edge of the table with the cap screws and spacers pro- vided. 5. Chec

F Blade Tension Proper blade tensioning is important for optimum bandsaw performance. See Figure 11 for the G location of the bandsaw tension controls. I Since a wide range of blades will work well in this saw, proper blade tension ultimately depends on the type and the size of blade you use. Thinner blades require less tension than wide blades. Too H much tension will result in blade breakage. A properly tensioned blade will track the cutting line accurately and the cut will be smoother. Figure

Blade Tracking Wheel Alignment Blade tracking involves positioning the blade on Wheel alignment is one of best ways to ensure the wheels of the bandsaw. There are two meth- that you get optimal performance from your band- ods of tracking: Center Tracking and Coplanar saw. Tracking. Center tracking, the easiest, is simply adjusting the tilt of the upper wheel so the blade When both wheels are aligned, or coplanar (see rides in the middle of the rubber tire.

5. Place your gauge up against both wheels in the positions shown in Figure 15. Figure 15. Coplanarity gauge placement. 6. Adjust the tracking knob to get both wheels coplanar. If the wheels will not go coplanar to each other, then move the lower wheel at the adjustment hub so they line up. If you are not familiar with the lower wheel adjustment hub, refer to the “Controls” section. Figure 14. Coplanarity gauge. 3.
