SAFETY PRECAUTIONS

7)Start and operate the SURFACE GRINDER only in a well ventilated area. Carbon Monoxide fumes given off by an engine are poisonous. Breathing these fumes can result in property damage and/or personal injury. Operate the SURFACE GRINDER only when/where visibility and light are adequate for the job at hand. Work carefully. Always hold the operator handle firmly with both hands. Wrap your fingers around the handle, keeping it cradled between your thumbs and fingers. Always make sure the operator handle is in good condition and free of moisture, pitch, oil or grease. Wear gloves to improve your grip. Never leave the SURFACE GRINDER running unattended.

8)Special care must be exercised on slippery conditions and on difficult, uneven surfaces. Watch for cracks, high spots and other, surface irregularities. Keep proper footing and balance at all times. The normal use of this machine is on level surfaces. Other terrains can be dangerous and should be avoided. Only properly trained operators should attempt these techniques.

9)Never start the engine or electric motor with the SURFACE GRINDER directly over cracked, uneven or irregular surfaces. Start the engine or electric motor according to the instructions as outlined in this manual.

10)Contact with a hot, engine muffler can cause property damage and/or personal injury. Remain clear of a hot, engine muffler. Do not over speed the engine by altering the governor setting or by disconnecting the engine governor. Serious damage to the engine and/or personal injury can result.

11)Clean and remove all accumulated foreign matter from inside the mainframe area after each use. This practice will maximize bearing and V-belt service life.

12)Because this SURFACE GRINDER is classified as a low cost, hand held, low horsepower, portable type machine, it is limited in the number of practical and/or suitable job applications. A particular job site, actual surface conditions, job specifications and operator skill/common sense may dictate that a different type of machine (with characteristics of higher purchase cost, being mounted to a carrier vehicle, with greater horsepower and less mobility), method and/or process be utilized to properly complete the job with the degree of efficiency and safety required. Contact the Customer Service Department for specific information regarding suitable job applications, job sites surface conditions and

operator experience/skill/common sense recommendations for this SURFACE GRINDER BEFORE utilization. There is no charge for this service.

MAINTENANCE, REPAIR AND STORAGE

1)Use only genuine, approved replacement parts and accessories for maintenance and repair. Use of parts and accessories manufactured by others can result in property damage and/or personal injury.

2)Follow the Service instructions as outlined in the appropriate section of this manual.

3)Always stop the engine or electric motor and disconnect the spark plug wire or power source cable BEFORE checking or working on the

SURFACE GRINDER.

4)Always properly maintain the SURFACE GRINDER. Frequently check all fasteners and individual parts. Built in safety features are effective only if they are maintained in good working condition. Replace any questionable part or assembly with a genuine, factory approved, replacement part. Do not forsake proper maintenance for the price of a few replacement parts. Proper maintenance does not cost...it actually pays dividends. Do not attempt any maintenance repair work not described in this manual. Have such work performed at your dealer's service facility.

5)A worn or damaged engine muffler is a fire hazard and may cause loss of hearing. Check to see that the muffler is in good condition. If the muffler is equipped with a spark arresting device, determine that it is in proper working condition at regular service intervals. Replace the spark arresting device with an approved replacement if there is any question of it integrity. It is the responsibility of the owner(s) and/or operator(s) to provide for and properly maintain a USDA approved, spark arresting muffler in an operating area specified by law. Check with appropriate governing agencies for more specific information. The SURFACE GRINDER must not be operated if the muffler is faulty or has been removed. Contact with a hot engine muffler can cause property damage and/or personal injury.

6)Do not operate the SURFACE GRINDER without the use of factory approved V-belt and diamond blade guards that are maintained in proper structural condition. Frequently inspect the guards for signs of wear, cracks and other signs of fatigue. If there is any question regarding the structural integrity and/or condition
