1.     The engine must be off and allowed to cool 

at least three minutes before adding fuel.

2.     Remove the fuel filler cap and fill the tank. 

(See engine manual for fuel capacity, fuel 
recommendation, and location of fuel cap.)

3.     Reinstall the fuel cap and tighten. Always 

clean up spilled fuel.

IMPORTANT: DO NOT OVERFILL!

This equipment and/or its engine 
may include evaporative emissions 
c o n t r o l   s y s t e m   c o m p o n e n t s , 
r e q u i r e d   t o   m e e t   E P A   a n d /
or CARB regulations, that will 
only function properly when the 
fuel tank has been filled to the 
recommended level. Overfilling 
may cause permanent damage 
to evaporative emissions control 
system components. Filling to 
the recommended level ensures 
a vapor gap required to allow for 
fuel expansion. Pay close attention 
while filling the fuel tank to ensure 
that the recommended fuel level 
inside the tank is not exceeded. Use 
a portable gasoline container with 
an appropriately sized dispensing 
spout when filling the tank. Do not 
use a funnel or other device that 
obstructs the view of the tank filling 
process.

Fill the fuel tank outdoors, never 
indoors. Gasoline vapors can ignite 
if they collect inside an enclosure. 
Explosion can result.

ADJUSTING TRIMMER HEIGHT

The height of cut can be set to five different 
positions ranging from 1.5 inches to 3.5 inches. 
Higher positions are useful when trimming 
tall grass or in conditions where frequent 
objects (rocks, small limbs) are on the ground. 
Lower positions will provide a more finished 
appearance. Recommended cutting height for 
the average yard is 2 inches. 

1.     

To adjust the trimming height, push the 
trimmer head height locking plate tabs on 
each side of the trimmer head and move 
trimmer head up or down to desired 
position. If the head will not disengage, 
slightly rotate the head while pushing the 
locking plate tabs.

2.     Release the tabs and be sure the trimmer 

head is locked into one of the 5 height 
positions.
