LORTONE QT66 Rotary Tumbler

SETTING UP YOUR MACHINE

Install The Barrel Guide: Using the machine screw provided, install the barrel guide under the frame edge as shown in the picture. Align the slot in the guide with the groove in the knurled nut on the barrel. Adjust the position of the guide so the slot is centered on the groove. Tighten the screw securely with the nut provided.

GETTING STARTED

Open the Barrel: Remove the nut and washer, and press down on bolt with your thumb while lifting up on the outside of outer lid with ﬁngers. If outer lid is difficult to remove, insert a washer between edge of outer lid and the barrel, twist to loosen. After outer lid has been removed, lift the inner lid out by center bolt.
Add Rocks: Fill the Barrel about 1⁄2 to 2/3 full of rock. Rocks should be of assorted sizes for best results.
Add Abrasive: Add 60/90 Silicon Carbide Abrasive. Use 10-level Tbsp for a 6 Lb. barrel. Use 20-level Tbsp for a 12 lb. barrel. Add water to cover rocks and abrasive. Do not overﬁll.
Close the Barrel: Wipe the mating surfaces of the barrel and inner lid clean with a damp cloth. Press inner lid into barrel until it rests on shoulder. Press outer lid ﬁrmly down onto the barrel. Install washer and tighten nut. The knurled nut only needs to be snug Do Not Use tools to tighten. Over-tightening of the nut can cause the inner lid to distort and leak.
Tumble : Plug the tumbler into a suitable outlet. Place the barrel on the tumbler making sure the groove in the barrel nut sits on the tumbler guide. Tumble for 2-3 days. Open and check the rocks. The rough edges should be wearing down. After 5-7 days, open the barrel and rinse the rocks in a bucket of water. DO NOT put the rinse water down a household drain as it will clog the drain!
IMPORTANT: Clean the rocks and barrel parts thoroughly using mild soap and water!
Repeat steps II through V: Use succesively ﬁner abrasives according to your tumbling instruction booklet and the chart below:

MAINTENANCE

LORTONE Tumblers are capable of operating 24 hours/day for years with proper care.

For best operation and results follow these simple, but important steps:

MOTOR: The motor is designed for continuous use and does not need oiling or other maintenance. It is normal for the motor to run hot to the touch.
CLEANING: The outside of the barrel should be kept clean. Clean by wiping with a wet soapy cloth and rinse well with fresh water. DO NOT put the barrel in a dishwasher or clean using solvents. If the outside of the barrel becomes so slick that it slips on the rollers, roughen slightly with very ﬁne sandpaper or steel wool.
BEARINGS: Oil each shaft bearing every 30 days of operation, using one drop of lightweight lubricating oil. Do Not Use excessive oil.
DRIVE BELT: Keep the drive belt tight enough to drive the barrel without being over tightened. Improper tension (too tight) can cause motor bearing failure and belt stretch. To adjust the belt, loosen the two motor mounting nuts, slide the motor to the right, and re-tighten the nuts.
DRIVE BELT REPLACEMENT: Remove the belt guard nut and loosen the motor mounting nuts. Remove the old belt and discard it. Carefully slip the new belt over the pulleys.
- Caution: Pulley edges are sharp! Replace the belt guard and tighten the belt guard nut.
