Section 4 - REPAIR & ADJUSTMENTS 

 

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. 

 
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 4.4. 
 
 

 

FIGURE 4.4 

 
5. Check blade for balance. If necessary, correct 
balance by grinding heavy end of blade. 
6.  Reinstall blade. See Figure 4.1. Check torque of 
blade retaining cap screw. Recommended torque 
should be 30 to 40 ft. lbs. 

 

NOTE: The following sections 4.2 through 
4.4 are for self-propelled models. 

 
4.2  WHEEL DRIVE CONTROL ADJUSTMENT 

1.  The wheel drive control is properly adjusted when 
there is 1/16” to 1/8” clearance between the inside of 
the spring hook and the inside of the clutch cable 
eye with the wheel drive control released. See 
Figure 4.5.

2.  To adjust, unhook upper spring from cable eye 

and rotate spring in direction required to extend 
or shorten spring length. 

3.  Rehook upper spring to cable eye and check 

clearance. Repeat procedure if required. 

 
NOTE: The vinyl spring cover should be kept over the 
spring at all times except for adjustments. 
 

4.  If the wheel drive control fails to return quickly to 
the “OFF” position when released, check for binding 
at the cable holdings located on the side of the right 
handle.  The upper clip should be located 2” below 
the upper knob; the lower clip should be 4” above 
the lower knob. The cable should slide freely with 
the clips installed at these locations.
