SECTION 2: CIRCUIT REQUIREMENTS 110V Operation 1 The Model G1052 has a /2 HP motor which oper- ates at 110V. It includes a complete cordset with a grounded plug that’s made for use with a grounded domestic 110V outlet. The G1052 motor will safely draw about 8 amps at 110V under load. If you operate the bandsaw on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist, and Figure 1.

SECTION 5: ADJUSTMENTS Blade Adjustments Blade tension and tracking are two of the most important factors affecting bandsaw perfor- mance. When the blade is properly tensioned and tracked, blade life will be extended, cuts will be straighter, and the bandsaw will run more smoothly. In order to optimize tension and track- ing, the two wheels must be co-planar (or in the same plane). Follow the steps outlined here in the order pre- sented for best results: (A) adjust tension, (B) Figure 4. Checki

Adjust parallelism (i.e., if the middle of the wheels are co-planar, but the sides are not). 2. Set a straightedge against the sides of the Figure 6. wheels. It should fully extend across both of them. Figure 5. 3. The straightedge must touch each of the out- side rims on both wheels. If the straightedge do
