twist to loosen. After outer lid
has been removed, lift inner lid
out by center bolt.
II. Add Rocks: Fill Barrel about
1⁄2 to 2/3 full of rock. Rocks
should be of assorted sizes for
best results.

Abrasive. Use 4 level
Tbsp for a 1.5 - 3 Lb.
barrel. Use 6-8 level
Tbsp for a 4 lb. barrel.

IV. 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.

V. 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 (45C). Tumble for 2-3 days.

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!

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 three motor mounting nuts, slide the motor to the
right, and re-tighten the nuts.
Slide motor
to adjust
belt tension.
Motor mounting nuts
DRIVE BELT REPLACEMENT: Remove the motor top
cover and loosen the motor mounting nuts. Remove the old belt
and discard. Carefully slip the new belt over the pulleys.
Caution: Pulley edges are sharp! Replace the motor top cover
and tighten the belt guard nut.
