Procedures
4Test 20 - Check Spark Plugs / Test 23 - Check Valve Adjustment adjustment
Tools: feeler gauge, crow foot wrench
- Adjust valve clearance with engine at room temperature
- Position piston at TDC of compression stroke (both valves closed), or set intake/exhaust valve fully open method
- Loosen rocker arm jam nut; turn pivot ball stud while checking clearance with a feeler gauge
- When clearance is correct, hold pivot ball stud and tighten rocker arm jam nut to specified torque with a crow foot wrench
- Recheck valve clearance to make sure it did not change
- Install rocker arm cover with a new gasket
Test 27 - Check / Adjust Governor adjustment
Tools: AC frequency meter
- Loosen governor clamp bolt
- Hold governor lever at wide open throttle position
- Rotate governor shaft counterclockwise (389/208/196cc) or clockwise (410cc) as far as it will go
- Tighten governor lever clamp bolt to 110 in-lbs (389/208/196cc) or 70 in-lbs (410cc)
- Turn speed adjustment screw counterclockwise three full turns to avoid overspeed
- Start engine and let warm up under no-load
- Connect AC frequency meter; no-load frequency should be 62.0-62.5 hertz
- Turn speed adjust screw until frequency/RPM is within limits
- Apply removable Loctite (Loctite 241) to speed adjust screw threads
Test 41 - CO Module Verification Test diagnostic
⚠ Do NOT insert the drill bit into the LED holes; damage to the LEDs will occur
Tools: 3/64 inch drill bit
- Do not install CO badging (decal) prior to performing this test
- Run generator under normal operation with no CO module notifications for a minimum of 65 seconds
- With generator running, insert blunt end of a 3/64 inch drill bit into test switch hole
- Hold the drill bit against the mounting panel until notification LEDs appear and generator shuts off
- Successful pin test shows both LEDs on solid (not blinking)
Determine what size generator you need operation
- Choose which devices you want to power at the same time.
- Record and add the running watts listed for each device that you need to power.
- Record the starting watt requirements for each device.
- Add the starting watts for the highest starting watt device plus the total running watts to determine the total watts requirements.
- Consult the specifications to find the correct generator for your needs.
