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 The Sander 1. BE AWARE OF DRUM OR FLAP ATTACHMENT ROTATION DIRECTION when sanding. 2. KEEP FINGERTIPS AWAY FROM MOVING PARTS. 3. 4. 5. NEVER USE EXCESSIVE FORCE WHEN SANDING. Doing so greatly increases the chance of personal injury, mechanical damage, or damage to your workpiece. ALWAYS FEED YOUR WORK AGAINST THE DIRECTION OF ROTATION. DO NOT OPERATE THE SANDER IF THE DRUM OR FLAP ATTACHMENT IS DAMAGED OR BADLY WORN.
SECTION 2: CIRCUIT REQUIREMENTS 110V Operation Grounding The Model G8749 is wired for 110V, single phase operation. Figure 1 depicts the typical grounded receptacle which should be used. In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. This tool is equipped with a power cord having an equipment-grounding conductor. See Figure 1.
SECTION 3: GENERAL INFORMATION Commentary Grizzly Industrial, Inc. is proud to offer the Model G8749 Drum/Flap Sander. This sander is a part of Grizzly’s growing 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 G8749 features a powerful 1 HP motor with a 1725 RPM arbor speed.
Unpacking The Drum/Flap Sander is shipped from the factory in a carefully packed carton. If you find the machine to be damaged after you’ve signed for delivery and the truck and driver are already gone, you will need to file a freight claim with the carrier. Save the containers and all packing materials for inspection by the carrier or their agent. Without the packing materials, filing a freight claim can be difficult. If you need advice regarding this situation, please call us.
SECTION 4: ASSEMBLY Securing Motor to Bench Attaching Flap Sander The sanding motor body must be securely mounted before the machine can be safely used. There are four 3⁄8" holes in the motor base which can be used to secure the machine to a tool stand or workbench. Figure 2 shows the approximate dimensions of the hole pattern. It is best to use the actual motor base as a guide for positioning the holes. The Sander can be temporarily mounted by using bolts with wing nuts.
Attaching Sanding Drum The Sanding Drums are shipped with abrasive sleeves already installed. Slide the sleeves off of the drum far enough to check to see which way the direction arrows run. See Figure 4. Be sure to deflate the drum completely to allow removal of the sleeve. Even with no air pressure it is a snug fit. Spindle Rotation Arrow Figure 5. Attaching inflatable drum. The Sanding Drums need to be inflated in order to retain the abrasive sleeve.
SECTION 5: OPERATIONS The inflatable sanding drum accepts hard or softsanding sleeves 31⁄4" and 43⁄4" diameter by 8". These are available in a variety of grits. See the current Grizzly catalog for prices and ordering information. Please review all safety rules for sanders and all power tools before attempting operation. The hints listed below are also worth your consideration: 1. Use great care when first engaging the workpiece against the drum or flap sander.
Drum Sanding Flap Sanding Drum sanding is perfect for performing sanding operations on edge contours. Inflate the drum to the desired air pressure using a hand pump. Use a soft sleeve and lower pressure when sanding contours with rounded or soft edges. A hard sleeve and higher pressure is desirable when the edge is to be sharp. Be certain to mount the abrasive sleeve on the drum so the direction of rotation of the sleeve will match the spindle rotation of the machine you are using.
SECTION 6: MAINTENANCE General The Flap/Drum Sander is ruggedly constructed to provide years of dependable service. To ensure that you enjoy maximum performance and longevity, we suggest the following routine maintenance: 1. Check all fasteners for tightness before each use. Tighten when necessary. 2. Keep the Sander clean for maximum efficiency and heat dissipation. Wipe away accumulated sanding dust and grime after each use. 3. Inspect sanding sleeves for excessive wear and damage. Replace if necessary.
Replacing Sandpaper Flaps Remove the Flap Sander from the machine. Set the assembly down on a bench or table top and then remove the top plate. It will be easier to reassemble the brushes and sandpaper if they are not all removed from the lower plate at the same time. Note that each retaining strip holds two pieces of the 114mm x 152mm (4.5" x 6.0") sandpaper. Select the proper replacement grit and cut to size. Loosen the two screws holding the retainer plate and remove the old sandpaper.
