• 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
