Chipping  
WARNING: Never operate the chipper shredder  
without chipper chute lowered into the operating  
position.  
Starting Engine  
Refer to the engine operator’s manual for the starting  
instructions.  
Branches up to two inches (model series CS 2210) or three  
inches (model series CS 3310) in diameter can be fed into the  
chipper chute. Observe the following guidelines when chipping  
branches:  
Shredding  
Yard waste such as leaves and pine needles can be placed in  
the hopper for shredding. After material has been processed by  
the shredder blade and flails, it will be forced out of the chute  
deflector, and, if attached, into a debris collection bag.  
Keep both hands firmly on the branch as you feed it into  
the chipper chute.  
Observe the following guidelines when shredding yard debris:  
Never feed more than one branch into the chipper chute at  
a time.  
Never attempt to shred material other than normal yard  
debris (leaves, twigs, pine cones, etc.).  
Never feed anything other than branches (or wood) into  
the chipper chute.  
Avoid shredding fibrous plants such as tomato vines until  
they are thoroughly dried out. Fresh vines do not shred  
well and tend to wrap themselves around the impeller and  
flails.  
Apply intermittent pressure (force, in short pulses) while  
feeding larger branches into the chipper chute, to avoid  
bogging or stalling the engine.  
Place reasonable amounts of debris into the hopper at a  
time. Do not overload the hopper.  
IMPORTANT: Never feed branches with a diameter greater  
than two (2) inches (Model Series CS 2210) or three (3)  
inches (model series CS 3310) into the chipper chute. Doing  
so can result in serious damage to your unit’s chipper  
blades, flails or impeller.  
Allow the material in the hopper to be drawn into the  
blades and shredded before adding additional debris  
to the hopper. Failure to due so may result in a clogged  
hopper, clogged chute deflector or a stalled engine.  
NOTE: For best performance, always operate the unit with  
sharp chipper blades. If a noticeable loss in performance is  
encountered while chipping branches, the chipper blades  
should be replaced.  
Avoid placing twigs longer than 24 inches into the hopper.  
Twigs longer than 24 inches may result in a clogged  
hopper.  
IMPORTANT: Never place branches with a diameter greater  
than 1/2-inch in the hopper. Doing so can result in serious  
damage to the unit’s shredder blade, flails or impeller.  
Clearing the Hopper  
Should the hopper become clogged with debris during  
operation, proceed as follows:  
1.  
Grasp the handle with both hands and gently agitate the  
chipper shredder to help loosen debris, drawing it into the  
impeller.  
If the clog does not clear, proceed as follows:  
1.  
Stop engine.  
2.  
Use your hands to remove any debris found near the top of  
the hopper.  
3.  
Use a branch (or other available device, i.e. broomstick) to  
dislodge debris located toward the base of the hopper.  
4.  
Restart engine.
