SECTION 6:  MAKING ADJUSTMENTS

WARNING: 

Do not at any time make any

adjustment to your lawn mower without first
stopping the engine and disconnecting the
spark plug wire.

Handle Height 

Your mower is shipped with the handle in the higher 
height position.To lower the handle height for your 
convenience, proceed as follows.

Figure 9

Remove the starter rope from the rope guide.

Remove the upper handle by removing the hand 
knobs and carriage bolts. Lay the upper handle out 
of the way, being careful not to bend or kink cables.

Remove the hairpin clips from the weld pins on the 
handle brackets. Press outward on the legs of the 
lower handle, and remove it from the mower.

Turn the lower handle around so the notches on the 
bottom of the lower handle are facing forward as 
shown in Figure 9. Reassemble, placing the bottom 
holes in the handle over the weld pins in the handle 
mounting bracket.

Reassemble the upper handle.

Place the hairpin clips in the inner holes in the weld 
pins. Reattach the starter rope.

Carburetor 

WARNING: 

 If any adjustments are made to

the engine while the engine is running (e.g.
carburetor), keep clear of all moving parts and
heated surfaces (e.g. muffler).

Minor carburetor adjustments may be required to 
compensate for differences in fuel, temperature, 
altitude and load. To adjust carburetor, refer to the 
engine manual.

NOTE: 

A dirty air cleaner will cause an engine to run

rough. Make sure air cleaner is clean and attached to
the carburetor before adjusting carburetor. 

Cutting Height 

An adjusting plate and thumb lever at each wheel 
position provides cutting height adjustment. Each 
adjusting plate has nine height positions. Height of cut 
will be changed when the thumb lever is moved from 
one hole to another. 

Simply depress the lever towards wheel and move 
wheel and lever assembly to desired position. All 
wheels must be placed in the same relative 
position. See Figure 10.
