⚠️ Safety glasses

Tumbler

• Do not store the tumbler canister on the tumbler. This causes the steel burnishing shot to become highly magnetized and not work as well. Please store it on the table!
• Always store the canister with the lid on and shot fully immersed, otherwise the steel shot will rust.

It rotates in one direction for about 15 minutes, and then automatically rotates to the opposite direction for 15 minutes. We suggest a two-way rotation, which is more efficient.

After selecting the direction you want, press the button in the center, then tumbler started to work.

You can choose a specific time by turning the time control button.

Tum Tumbler has self-protection function. When it works for a long time, it will stop and rest. When the motor is cooled down, it will continue to work.

Pickle Pot

• Only use copper tongs in pickle solution, never steel!
• Neutralize pickle solution in the sink by pouring it into a bowl of 1/4 baking soda and 3/4 water mixture.
• Unplug before leaving the studio!
• Silver work should not be used in a pickle pot where copper/bronze/brass work is pickled, otherwise it will become copper plated. Neutralize and make fresh pickle if this is the case.

Buffs Buffs should not be gummed up with polishing compound! Use compound sparingly so the buffs stay fluffy.
