SHREDDING

Yardwastesuchas leavesandpineneedlescanbe placedinthe hopperforshredding.Aftermaterialhasbeenprocessedbythe shred- derbladeandflails,it willbeforcedoutof the chutedeflector,and,if attached,into adebriscollectionbag.

Observethefollowingguidelineswhenshreddingyarddebris:

• Neverattempttoshredmaterialotherthannormalyarddebris (leaves,twigs,pinecones,etc.).

• Avoidshreddingfibrousplantssuchas tomatovines,palmfronds, etc.,untiltheyare thoroughlydriedout. Freshvinesdo notshred wellandtend towrapthemselvesaroundtheimpellerandflails.

• Placereasonableamountsofdebrisintothe hopperat a time. Do notoverloadthe hopper.

• Allowthe materialin the hoppertobedrawnintothebladesand shreddedbeforeaddingadditionaldebristo the hopper.Failureto duesomayresultin acloggedhopper,cloggedchutedeflectoror a stalledengine.

CHIPPING

Branchesupto3" in diametercanbefedintothe chipperchute. Observethefollowingguidelineswhenchippingbranches:

• Keepbothhandsfirmlyonthe branchasyoufeedit intothe chipperchute.

• Neverfeedmorethanonebranchintothe chipperchuteata time.

• Neverfeedanythingotherthanbranches(orwood) intothe chipperchute.

• Applyintermittentpressure(force,inshortpulses)whilefeeding

larger(3-inchdiameter)branchesintothechipperchute,toavoid boggingor stallingtheengine.

IMPORTANT:Neverfeed brancheswitha diametergreaterthan three(3)inchesintothechipperchute.Doingsocan resultin serious damageto yourunit'schipperblades,flailsor impeller.
