A complete original manual for the 2CRH typically includes: iwata 2crh bundy clock manual

  1. Installation & Setup: Leveling the unit, securing it to a wall/stand, and connecting to an AC power source (if electrically assisted—note: many 2CRH models are purely mechanical with a manual lever).
  2. Loading & Aligning Time Cards: How to insert card stock, adjust card guides, and set the print registration so stamps land in the correct daily columns.
  3. Setting the Time & Date: Instructions for manually advancing or correcting the analog clock face, setting the day-of-week and month/date wheels (mechanical linkages, not digital).
  4. Print Hammer & Ribbon Adjustment: Adjusting the print force for clear impressions, replacing/re-inking the ribbon, and cleaning the metal type wheels.
  5. Troubleshooting Common Issues: Jams, partial prints, incorrect date display, and lever resistance.
  6. Lubrication Schedule: Recommended oil points (light machine oil, not grease) and frequency (every 6–12 months).
  7. Parts Diagram & Exploded View: Essential for identifying worn components like springs, pawls, or the main drive gear.

Section 3: Programming the Iwata 2CRH (The "Hard Part")

Most user manuals are lost because the programming section is complex. The Iwata 2CRH uses a series of DIP switches and rotary dials located behind the front panel or inside the mechanism cover. Iwata 2CRH Bundy Clock Manual Model: 2CRH (Two-Column

Setting the Time

  1. Open the top cover.
  2. Locate the Time Setting Knob (often a small wheel or knob located near the face of the clock mechanism).
  3. Turn the knob clockwise (or as indicated by arrows on the mechanism) until the hands on the internal clock face show the correct time.
  4. Note: Do not move the clock hands counter-clockwise, as this can strip the gears in mechanical clocks.

2. How the Iwata 2CRH Works

The clock uses a synchronous motor (locked to mains frequency) to keep accurate time. When an employee inserts their time card into a slot, it presses a micro-switch or mechanical trip lever. That activates a solenoid which:

  1. Pulls the print hammer forward.
  2. Advances the date/print wheels to current time.
  3. Presses the ribbon and card against a fixed platen.
  4. Prints the precise hour/minute, AM/PM (or 24h), and date in one or two lines.

The "2C" in the model likely refers to 2 Color capability: The clock can switch ribbon position (black for on-time, red for late) based on a mechanical cam connected to the minute wheel.
