SHREDDING

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

Observethefollowingguidelineswhenshreddingyarddebris:

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

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

• Placereasonableamountsofdebrisintothe hopperata time. Do notoverloadthe hopper.

• Allowthe materialin thehopperto bedrawnintothebladesand shreddedbeforeaddingadditionaldebristo thehopper.Failureto duesomayresultin acloggedhopper,cloggedchutedeflectoror a stalledengine.

CHIPPING

Branchesupto3" in diametercanbefedintothechipperchute. Observethefollowingguidelineswhenchippingbranches:

• Keepbothhandsfirmlyonthe branchas youfeed itintothe chipperchute.

• Neverfeedmorethanonebranchintothechipperchuteat a 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.

NOTE:Forbestperformance,alwaysoperatetheunitwith sharp chipperblades.If a noticeablelossin performanceisencountered whilechippingbranches,thechipperbladesshouldbe replaced.
