• 4.5 in/ 115 mm Model 450 • 3.75 in/ 95 mm Model 375
New Terminologies
• Only 6 basic components
• Knob• Eyelet carrier• Core• Spool• Cover
Shindaiwa’s Unique New Head!
• In-house design• US Pat #6,952,877• Others pending• Unique features• Glass-filled nylon
Low-Vibration
• Top (winder) serves as vibration-dampening disk
• Most parts secured to gearcase• Rigid control of dimensions, molding process
• Diecast eyelets shaped for less line breakage
• Slotted for faster loading if head disassembled
Replaceable Eyelets
Less Line Welding
• Separate spool for each line
• Line exists in opposing direction for line tensioning
Large Wear Surface At Base
• Less frequent replacement of bump knob• Less chance of devoting/scalping
Better Sealing• Double-wall design prevents internal debris buildup• Maximizes rigidity, strength
Fastest Line Fastest Line LoadingLoading
•Load right off the spool!
Demonstration is Essential!
•This head has extremely unique features
•It must be demonstrated for maximum impact
Assembly NoteAssembly Note
• Mount arbor bolt securely into gearcase.
• Thread head onto arbor bolt.
• Will cause excessive vibration if not tight in gearcase!
Head DisassemblyHead Disassembly (TSB272) (TSB272)
• Remove cover with your thumbs.
• Thumb pressure is much greater than finger pressure!
• Two clicks when properly assembled!

Design Differences vs. Competitive Design Differences vs. Competitive HeadsHeads
• Eliminate small-diameter bump knob.
• Cover is the advancing mechanism.
• Larger surface area.• Less wear.• Less divoting, scalping.• No disassembly to reload
line (30 sec. or less)!• Stays cleaner inside
ConclusionConclusion• Two serious threats to Stihl’s
AutoCut business!
