aintenance
Under normal operating conditions, the bevel gear sets and roller bearing should be inspected
every 100 hours of operation and lubricated as needed. If exceptionally difficult work has been
performed or if excessive coolant has contaminated the gear sets and roller bearings, inspection
should be done much more frequently.
The bore of the cutting head, feed nut and mandrel must be kept cleaned and oiled.

tool bit into one of the slots on the cutting head. Clamp machine into a bench vise. Using the lock
nut tool and a torque wrench, tighten locknut to 50 ft. lbs. while rotating the main housing. Once

After 40 hours of operation, flush the air motor with a solution of three parts cleaning solvent and
one part air motor oil. After flushing, add 1 oz. (30 cc) air motor oil into air line and run air motor
for one minute. It is very important that the components of the mandrel assembly remain clean and
free from corrosion. The legs and machine surfaces should be cleaned and oiled on a daily basis.
