Unpacking

Remove staples, break glue on top flaps, or cut 
tape at carton end and peel along top flap to open 
carton.

Remove loose parts if included with unit (i.e., 
owner’s manual, etc.).

Cut along corners and lay carton down flat.

Remove packing material.

Roll or slide unit out of carton. Check carton 
thoroughly for loose parts.

Tools Required 

1.

Pair of Pliers 

2.

Phillips Screwdriver 

  

3.

7/16" or Adjustable Wrench 

 Required for models with hardtop grass bags only.

NOTE: This operator’s manual covers various models
of lawn mowers. Follow only those instructions which
pertain to your unit.

Disconnect Spark Plug Wire

Figure 1

Before setting up your lawn mower, disconnect  
spark plug wire from the spark plug, and ground it 
against the engine. See Figure 1 .

In the case of lawn mowers where engine is 
equipped with a rubber boot, attach rubber boot to 
a bolt on the engine to ground. See Figure 1.

Assembling Handle

NOTE: Reference to right or left hand side of the mower
is observed from the operating position.

Remove any packing material which may be 
between the upper and lower handles for shipping 
purposes. 

Pull up and back on the upper handle to raise the 
handle into the operating position. Make certain the 
lower handle is seated securely into the handle 
mounting brackets. 

Figure 2

Tighten the hand knobs on each side of the handle 
(carriage bolts must be seated properly into the 
handle). See Figure 2.

NOTE:  Your mower is shipped with the handle in the
higher height position. If you wish to lower the height of
the handle, refer to the Adjustment Section at this time.

Using a pair of pliers, squeeze one leg of the lower 
handle against the handle mounting bracket. 
Remove the hairpin clips from the outer hole in the 
weld pins on the handle mounting brackets. Insert 
the hairpin clip into the inner hole on the weld pin. 
See Figure 3. Repeat on other side.
