You must install the Grinding Wheel (54) before using your tool.
1.Place the Backing Washer (2) on the Arbor Spindle (7) as shown, making sure it fits tight.
2.Place the Grinding Wheel (54) on top of the Backing Washer (2), making sure the bore of the Grinding Wheel fits onto the step of the Arbor Spindle (7).
3.Place the Disc Locking Nut (1) onto the Arbor Spindle (7) with the concave recessed side against the grinding wheel.
4.Press in and hold the Spindle Lock (22). Be sure that the Spindle Lock has engaged in the Arbor Spindle (7) and is preventing it from turning.
5.While holding in the Spindle Lock (22) tighten the Disc Locking Nut (1) by turning it clockwise with the Spanner (501). Tighten securely.
6.Before using the tool, let it run for a minute, checking to be sure there is no excess vibration. If there is excess vibration, the grinding wheel is either not installed properly, or is damaged. Unplug the tool, and reinstall or replace the Grinding Wheel.
7.Removing the grinding wheel is the reverse of these steps.
About Power Grinders and Grinding Wheels
54
While an extremely useful tool, power grinders can be dangerous if damaged or used improperly.
1.Grinding wheels are made of aggregates of a cutting material (grit) such as Aluminum Oxide, an epoxy binder and usually a fabric matrix. During manufacture, the grit portion of the wheel is bonded to steel flanges which provide an area to slide onto the arbor and fix in place using the arbor nut.
2.Grinding wheels come in dimensional sizes, speed ranges and grit sizes.
3.This grinder is designed to accept 9” diameter grinding wheels, with an arbor hole diameter of 5/8”. The included adapter will allow you to use arbor sizes of 7/8”. Do not use wheels of any other size.
4.This grinder has a maximum speed of 6500 rpm. WARNING: Do not use a grinding wheel which is not rated for at least this speed. Using lower speed rated wheels at higher speed may cause the grinding wheel to come apart and be ejected from the grinder at high speed, possibly causing severe personal or property damage.
5.Grinding wheels are identified by the material which makes up the grit, the recommended work piece material, and a grit number which indicates the coarseness of the grit. Lower numbers are more coarse. Coarse grits cut faster, but leave a rough surface. Finer grits (higher grit numbers) cut more slowly, but leave a more finished surface. Select the grit which is appropriate to the job at hand.
6.During use, grinding wheels may become unevenly worn, cracked or chipped.Wheels which are damaged in this way will usually cause the grinder to vibrate. WARNING: Damaged grinding wheels may break apart during use, possibly causing injury. Never use a damaged or unevenly worn grinding wheel.
