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 substitute for proper accident prevention measures.
Safety Instructions For Power Tools 9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.
Additional Safety Instructions For Buffers 7. DO NOT allow your hands to come into contact with buffing wheels during operation. Abrasive accessories have the ability to remove a lot of material, including skin, very quickly. MAKE SURE BUFFER IS SECURED FIRMLY TO A BENCH OR STAND BEFORE USE. Any “wobbles” must be corrected by shimming or blocking before operation. 8.
SECTION 2: CIRCUIT REQUIREMENTS 110V Operation The Model H4380 is wired for 110V. The 1⁄2 H.P. motor will safely draw 3.5 amps at 110V. If you operate this machine 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 a power failure still occurs, contact a qualified electrician or our service department. A 10 amp circuit should be used with this buffer.
SECTION 3: INTRODUCTION Commentary We are proud to offer the Grizzly Model H4380 8" Buffer. The Model H4380 is part of a growing Grizzly family of fine woodworking machinery. When used according to the guidelines set forth in this manual, you can expect years of trouble-free, enjoyable operation and proof of Grizzly’s commitment to customer satisfaction. The Model H4380 offers a 1⁄2 HP, 3450 RPM, 110V motor. A number of buffing wheels for the Model H4380 are available through the Grizzly catalog.
Unpacking Mounting The Model H4380 is shipped from the manufacturer in a carefully packed carton. If you discover the machine is damaged after you have signed for delivery, immediately call Customer Service for advice. The Model H4380 weighs approximately 17 lbs. Make sure the workbench on which you plan to mount the buffer is sturdy enough to hold the weight of the machine. The workbench should have a level surface and be heavy, or attached to the floor, so it will not move during operation.
SECTION 6: OPERATIONS Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. ! Disconnect power to the machine when performing any maintenance, assembly or adjustments. Failure to do this may result in serious personal injury. Wear safety glasses during the entire operation process. Failure to comply may result in serious personal injury. Using this machine produces sawdust which may cause allergic reactions and respiratory problems.
Buffing & Polishing For buffing and polishing, Grizzly offers a broad line of buffing wheels and polishing compounds. Please refer to our current catalog for more information on these. To buff or polish with the buffer: 1. Make sure the power cord is unplugged and remove the 5⁄8" hex nuts at the end of each shaft. Facing the machine, the left-hand shaft has left-handed threads. The right-hand shaft has right-handed threads. 2.
Buffing Wheel Selection Buffing wheels are available for most types of metals and for different stages in the buffing process. The following pictures and descriptions describe some of the more common wheel types: Check with your current Grizzly catalog for availability on any of these wheel types. Loose Muslin Soft feather-edged muslin stitched together near the center leaves the outer edge to provide a wide angle, fine polishing surface. Perfect for polishing stainless steel, chrome, gold or silver.
Buffing Tips • Keep buffing wheels raked out before each use and when buildup gets heavy during use. “Raking” means to clean the buffing wheels with a wheel rake to remove buildup compounds and metal particles. An old rough-cut saw blade or a large hacksaw blade will also work as an alternative to a wheel rake. ALWAYS use light pressure when raking wheels! • Do not mix two different compounds on the same wheel. For best results, use a separate wheel for each compound.
SECTION 7: MAINTENANCE ! Miscellaneous Disconnect power to the machine when performing any maintenance, assembly or adjustments. Failure to do this may result in serious personal injury. Lubrication Shielded and pre-lubricated ball bearings require no lubrication for the life of the bearings. All bearings are standard sizes, and replacements can be purchased from our parts department or a bearing supply store. -12- Always be aware of the condition of your buffer.
