The Model H4378/H4379 weighs 22/27 lbs. Make sure the workbench on which you plan to mount the grinder is sturdy enough to hold the weight of the machine and any downward pressure that may be applied during operation. The workbench should have a level surface and be heavy, or attached to the floor, so it will not move during operation. To mount the grinder:
•Pick a spot on the workbench that will allow enough room to move the size of an antici- pated workpiece around the grinder. The operator (and possibly bystanders) should have enough room to stand out of the way in an emergency.
•Mount the grinder to the workbench with bolts that are long enough to exceed the thickness of your workbench and the grinder base. Secure each bolt with flat washers, a lock washer and a hex nut. Because sizes vary for each individual situation, the hard- ware in this step is not included with the Model H4378/H4379.
•Mount the grinder in an area with proper lighting and near electrical outlets. Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to han- dle amperage requirements. Keep power or extension cords clear of
Make your shop “child safe.” Ensure that your workplace is inaccessible to children by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting, or operating equipment.
The tool rest provides a surface that can be used to support the workpiece during grinding. Certain types of grinding may require jigs or accessories to assure the proper angle of the workpiece against the wheel.
The tool rest attaches to the inward side of the wheel guard; it should be positioned as close to the grinding wheel as possible. Insert the 1Ú2" x 1Ú4" hex bolt with a flat washer and a lock washer through the rest support, and thread it into the tapped hole. Repeat this installation for the oppo- site side wheel. The tool rest can be adjusted by loosening these bolts and moving the bracket. Always retighten before using the machine.
Eye Shields
OSHA requires that the eye shield be positioned between the grinding wheel and the operatorÕs face during grinding. This lessens the possibility of sparks or metal bits flying directly at the opera- tor.
Attach each support bracket to the top end of the wheel rim guards with the knob bolts. Note that the brackets are slotted to allow up and down adjustments.
Snap the eye shields into the grooves on the sup- port brackets. The shields should be able to swiv- el up and down.
