Protect the power cable from high temperatures, oils, paint thinners and make sure that the cable is not
hanging over sharp edges.
Inspect the power cable regularly. If damaged have it replaced by qualified technician. Inspect extension
cables regularly. If damaged, have it replaced.
If you need to use an extension cable, use cable with appropriate power rating. Use only completely
unwound. Inspect extension cables regularly. Damaged cable must be repaired or changed immediately.

• Clean the sliding surfaces and surfaces with no paint coating with turpentine or paraffin oil to remove the
conservation grease.
• Then lubricate it with oil.
• Inspect position of all parts.
• Before switching your machine on, make sure that the main switch and the direction switch are in the OFF
position.

OPERATION
Drive train drawing
• Using the rpm/speed regulator set the revolutions to minimum.
• Connect the power cable to the wall outlet and turn the main switch and the direction switch to ON
position. Let the machine run for at least two minutes to make sure that it is working properly.
• Then slowly adjust the revolutions to the desired value.
• Before putting the machine in reverse, switch it off and set the revolutions/rpm to minimum. Then set the
reverse turning direction and switch the machine on.
NOTE: If you will not set the speed control to the minimum before putting the machine in reverse, you will
damage the electronic rpm control unit.
• If you wish to change the toothed gear, you must stop the machine first. The "L" position refers to the
lower wheel. The "H" position refers to the upper wheel.
• If, during the machine operation the electric power supply suddenly shuts off, turn the speed regulator to
the lowest revolutions setting.
• When the power comes back on, turn the switch to the "ON" position to restore the working process.
Additional notes
• Your machine is equipped with overload protection, which limits the feed.
• When the main chuck turns within the lower gear speed ratio (the lower toothed gear has been selected 1,000 rpm), the allowed feed speed is up to 4 mm (0.16").
• When the main chuck turns within the upper gear speed ratio (the upper toothed gear has been selected 1,000 rpm), the allowed feed speed is up to 2 mm.
• If the feed speeds are set higher than the above described values, the protection system will shut the
electric power supply off.
