GENERAL SAFETY RULES 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 meas ures.
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 Grinders 1. ALWAYS WEAR a face shield and/or safety goggles. 2. SECURE THIS GRINDER firmly to a benchtop or stand. 3. NEVER USE A GRINDING WHEEL which has evidence of cracking or chips. “Ring Check” the wheel to test its integrity (See Page 9 for checking procedure). 4. USE ONLY PROPERLY SIZED WHEELS which have the right bore size and overall diameter. 5. DRESS THE GRINDING WHEEL when its surface becomes rutted or uneven.
SECTION 2: CIRCUIT REQUIREMENTS 110V Operation Grounding The motor supplied with the G9717 must be operated at 110V. Use an outlet configuration as shown in Figure 1. Under normal use, the motor draws approximately 2-3 amps @ 110V. We recommend a 15 amp circuit breaker for 110V operation. This should be satisfactory for normal use, while providing enough protection against motor damage caused by power surges.
SECTION 3: GENERAL INFORMATION Commentary We are proud to offer the Grizzly Model G9717 6" Grinder. This Grinder is part of a growing Grizzly family of fine metalworking machinery. When used according to the guidelines set forth in this manual, you can expect years of troublefree, enjoyable operation and proof of Grizzly’s commitment to customer satisfaction. The Model G9717 is intended for home and hobby-type use. It features a 1⁄3 HP, 110V motor, two 6" grinding wheels, one 60 grit and one 30 grit.
SECTION 4: ASSEMBLY Tool Rest Eye Shield The Tool Rest provides a surface which 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 piece against the wheel. The Eye Shield should be positioned between the grinding wheel and the operator’s face during grinding. This lessens the possibility for sparks or metal bits to go flying directly at the operator.
Mounting to Bench Notes The grinder base has two holes directly under the wheel shaft. These holes can be used to mount the grinder to a workbench, table top, or other solid surface. Since grinding does develop a lot of force, it is best to mount the grinder solidly before using. If you wish for the grinder to remain portable, it can be temporarily clamped to a table. Just make certain no part of the clamping device interferes with the wheels or the tool rests.
SECTION 5: OPERATIONS Wheel Selection Starting and Stopping Aluminum oxide and silicon carbide wheels are marked in a somewhat uniform manner by all the major manufacturers. Understanding these markings will help you understand the capabilities of various wheels. Always refer to the manufacturer’s grinding recommendations when selecting a wheel for your project. Once assembly has been completed, the G9717 Grinder is ready for use in the shop.
Wheel Mounting Before mounting any wheel, check it for integrity by performing a “ring check”. Balance the wheel on one finger, then lightly tap the rim of the wheel with a piece of wood such as the handle of a hammer. The wheel should have a ringing or harmonic type of sound. If it responds with a dull thud it may indicate that the wheel has cracks. Do not use a wheel which is suspected of having cracks, or if there are visual chips, nicks or dents in the wheel surface.
SECTION 6: MAINTENANCE General Grinding Wheels Make a habit of inspecting your Grinder each time you use it. Check for the following conditions and repair or replace when necessary: The grinding wheel should be inspected before every use. Use the ring check method noted in the Grinding Wheel section in Operations to verify the structural integrity. If using coolant during grinding, always run the wheel for 5-10 minutes at the end of the operation to remove any coolant from the wheel.
TROUBLESHOOTING This section covers the most common processing problems encountered in grinding and what to do about them. Do not make any adjustments until grinder is unplugged and moving parts have come to a complete stop. SYMPTOM POSSIBLE CAUSE Motor will not start. 1. 2. Low voltage. 1. Open circuit in motor or loose 2. connections. Check power line for proper voltage. Inspect all lead connections on motor for loose or open connections. Motor will not start; fuses or 1. circuit breakers blow. 2.
