Your CZ-5 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-5 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.
