How should I clean the adaptor after use?
Clean the adaptor with a suitable degreaser and a soft brush, then wipe dry with a clean cloth. Store it in a dry place.
Troubleshooting
Adaptor does not thread in smoothly.
Check for damaged threads in the cylinder head or on the adaptor. Ensure you are using the correct adaptor for the engine. Do not force the adaptor; hand-thread it first to check alignment.
Air leaks around the adaptor during testing.
Ensure the adaptor is tightened sufficiently (but not over-tightened) and that the 47mm sealing thread is clean and making full contact. Consider using a small amount of PTFE tape on the threads if the engine design allows and it doesn't interfere with the seal.
Inaccurate compression readings.
Verify that the adaptor is fully seated and sealed. Ensure the connected compression test kit is functioning correctly and calibrated. Confirm the engine is being tested under the correct conditions (e.g., warm engine, throttle open).
Adaptor appears damaged.
Do not use the adaptor if threads are stripped, the sealing surface is marred, or the body is cracked. Replace the adaptor to ensure safety and accuracy.

Setup, Compatibility & Care
Setup:
Ensure the engine is at the correct temperature for testing as per the vehicle manufacturer's specifications.
Carefully remove the appropriate glow plug from the cylinder to be tested.
Thread the Laser Tools Diesel Compression Test Adaptor (7236) into the glow plug aperture by hand, ensuring it enters straight.
Tighten the adaptor gently. Avoid over-tightening. Ensure the 47mm sealing thread makes good contact.
Connect your Laser 4510 compression test kit or 5140 cylinder leakage tester to the adaptor.
Perform the compression test as per the kit's instructions.
