MAINTENANCE

Your CZ-3D doesn’t require a lot of care. It’s built with high quality materials but there are a few things you should do to keep it in peak operating condition.

1.If you’re not going to be using it for a while, take the batteries out. Acid damage caused by leaking batteries can be severe.

2.Avoid extreme temperatures. Don’t leave it inside a closed car sitting in the sun, or even worse, the trunk of a car.

3.If you “scrub” the search coil on the ground, you’ll eventually wear through the bottom of the coil. Replacement coils are expensive. Instead, invest in a coil cover. They’re cheap.

4.Keep your CZ-3D dry and clean. If you’ve been working in or around salt water or dust, wipe it down with a damp cloth and dry it with a hair dryer (low or no heat) or dry cloth. Remove and clean the lower stem. Keep the lock nut free of sand and dirt.
