 4. Safety precautions 5. Set up

 ENGINE 

•  Using attached 4 bolts, secure the connection firmly 

with equal force. 

 HANDLE

1. Loosen the 4 bolts on the upper cap and insert the 

handles equally. Retighten the bolts.

2.  Put the handle assembly into the bracket and put the 

upper cap over it. Tighten the cap securely.

 CONNECTING THROTTLE WIRE 

1.  Remove the air cleaner cover.

2.  Connect the end of the throttle wire to the joint on the 

top of the carburetor. 

NOTE

When installing the cleaner cover, make sure to put the 
high-tension wire in it.

1.  What causes blade thrust:

Blade thrust can occur when the moving blade 
contacts an object that it cannot cut. This contact 
causes the blade to stop for an instant and then 
suddenly move or ”bounce” away from the object 
that was hit. The operator can lose control of the 
unit and the blade can cause serious personal 
injury to the operator or any person nearby if the 
blade contacts any part of the body.

2.   How  you  can  reduce  the  chance  of  blade 

thrust:

(1) Recognize that blade thrust can happen. By 

understanding and knowing about bounce, you 
can help eliminate the element of surprise.

(2) Cut fibrous weeds and grass only. Do not let 

the blade contact materials it cannot cut such 
as hard, woody vines and brush or rocks, 
fences, metal, etc

(3) Be extra prepared for blade thrust if you must 

cut where you cannot see the blade making 
contact such as in areas of dense growth.

(4) Keep the blade sharp. A dull blade increase 

the chance of blade thrust.

(5) Avoid feeding the blade too rapidly. The blade 

can bounce away from material being cut if the 
blade is fed faster than its cutting capability.

(6) Cut only from your right to your left.
(7) Keep your path of advance clear of material 

that has been cut and other debris.

3.   How you can maintain the best control:

(1) Keep a good, firm grip on the unit with both 

hands. A firm grip can help neutralize bounce. 
Keep your right and left hands completely 
around the respective handles.

(2) Keep both feet spread apart in a comfortable 

stance and yet braced for the possibility that 
the unit could bounce. Do not overreach. Keep 
firm footing and balance.
