Section 4 - ADJUSTMENTS & REPAIR 

 

WARNING 

DO NOT attempt any maintenance, adjustments or 
service with engine and blade running. STOP engine 
and blade. Disconnect spark plug wire and secure 
away from spark plug. Engine and components are 
HOT. Avoid serious burns, allow sufficient time for all 
components to cool. Wear heavy leather gloves when 
handling or working around cutting blades. Blades 
are extremely sharp and can cause severe injury. 

 

4.1  MOWER BLADE REPLACEMENT 

4.1.1.  STANDARD BLADE WEAR LIMIT 
1.  
Inspect blade frequently for signs of excessive 
wear or damage.  See Figure 4.1. 

 

 

FIGURE 4.1 

 

WARNING 

DO NOT use a cutting blade that shows signs of 
excessive wear or damage. Refer to Section 
“MOWER BLADE REPLACEMENT” for proper blade 
inspection and service procedures.  

 
4.1.2. BLADE SHARPENING 
1.
  Disconnect spark plug wire and secure end away 
from plug. 
 

IMPORTANT: DO NOT tip machine with carburetor or 
spark plug down. Oil from crankcase will saturate the air 
filter and cause the engine to be hard to start or not start at 
all. If contamination does occur, the air filter will have to be 
replaced. 
 
 
 
 
 
 
 
 

2.  Tilt mower up on its rear wheels.  
3.  Remove blade. See Figure 4.2. 
 
 

 

 

 

FIGURE 4.2 

 

4.  Sharpen blade on a grinding wheel at an angle of 22 
to 28 degrees. DO NOT sharpen blade beyond original 
cutting edge. See Figure 4.3. 

 

 

 

FIGURE 4.3 

 
5. Check blade for balance. If necessary, correct 
balance by grinding heavy end of blade. 
6.  Reinstall blade. See Figure 3.2. Check torque of 
blade retaining cap screw. Recommended torque 
should be 30 to 40 ft. lbs.
