CONCRETE CUTTER USE AND CARE 

 

Do not force the Concrete Cutter to perform an operation other than its intended use. Concrete 
cutters do a better and safer job when used in the manner for which they are designed. Plan your 
work, and use the correct Concrete Cutter for the job. 

 

Check for damaged parts before each use. Carefully check that the Concrete Cutter will operate 
properly and perform its intended function. Replace damaged or worn parts immediately. Never 
operate the cutter with a damaged part. 

 

Place the power switch in the locked or off position before making any adjustments, changing 
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the 
tool accidentally. 

 

Store the Concrete Cutter when it is not in use. Store it in a dry, secure place out of the reach of 
children. Inspect the cutter for good working condition prior to storage and before re-use. 

 

Use only accessories that are recommended by the manufacturer for use with the Concrete 
Cutter. Accessories that may be suitable for one Concrete Cutter may create a risk of injury when 
used with another Concrete Cutter. 

 

Keep guards in place and in working order. Never operate the Concrete Cutter without the guards 
in place. 

 

Keep the Concrete Cutter blade clean. 

 

Do not leave the Concrete Cutter running unattended. 

 

Shut off the fuel valve when the engine is not in use. 

 

Only use the recommended fuel to avoid damaging the equipment. 

 

Oil does not come with the machine. Add oil to engine before the first use. 

 

Check oil levels before operating the machine. 

 

DO NOT refuel the engine while it is still hot. Fuel is flammable. 

 

DO NOT service engine while it is still hot.
