Hitachi 303-745 Spare Part - Return Spring

Hitachi 303-745 — Return Spring (original Hitachi)

Description: A genuine Hitachi coiled return spring (part number 303-745) used in the return/restore mechanism on Hitachi slide-compound saws. It’s the small coil spring that provides the restoring tension for the safety/sub‑cover / lock assemblies so the guard/lever returns to its home position reliably.

Compatibility (example models): Designed for Hitachi slide compound saw model C8FS (including C8FS variants shown in the parts diagrams). The part is listed in the C8FS parts breakdown as “Return Spring” (item 165), adjacent to the safety cover and sub‑cover/lock lever components.

What you’ll get and fit notes:

- Exact original Hitachi part 303-745 marked in the C8FS spare-parts diagram (drop‑in fit where the return spring sits under the sub‑cover / near the lock lever).

- Typical replacement task: remove the sub‑cover or nearby guard, swap the broken or fatigued spring for this part, confirm correct hook/orientation so the lever/cover returns smoothly. (Refer to your model diagram for the spring’s seating and orientation.)

Condition and inspection: Replace if the spring is stretched, cracked, or loses consistent tension; a fresh 303-745 restores positive return action and proper safety/locking behavior.
