freely up and down. To tighten the upper jaw screw, place a hex wench in the small set screw
located on the back side to hold it in place when the attachment screw on the front side is
tightened.
To thoroughly clean the diamond coated surfaces of
the clamp heads, remove the adjustment knob screw
to expose the inside surfaces of the clamps. Using the
cleaning stone provided with your machine (you can
also use a small tooth brush or a sharpening stone for
knives), scrub the diamond coated plates until all debris
is removed. Clean any dust or residue with a damp cloth
and re-assemble the clamp head.
To thoroughly clean the diamond coated surfaces of the
string gripper jaws, remove the gripper drum from the motor
shaft by loosening the drum attachment screw located at 5
o'clock on the side surface of the gripper drum, and sliding
the gripper drum off the shaft.
Note: To provide easier access to the attachment screw,
press the tensioning button switch to rotate the gripper
drum. When the screw is positioned at the top of the drum,
switch the power off on the machine to stop the gripper drum
from turning and remove the screw.
Remove the gripper jaws from the gripper drum by removing
the 4 cap screws that attach the jaws to the drum. When
removing the grippers, take care to not loose the compres-
sion springs inside the cavities of the lower gripper jaw. With
the gripper jaws removed from the drum, using the cleaning
stone provided with your machine (you can also use a small
tooth brush or a sharpening stone for knives), scrub the
diamond coated plates until all debris is removed. Clean any
dust or residue with a damp cloth and wipe down the gripper
drum surfaces to remove any residue as well.
To re-assemble the gripper jaws to the drum, fit the springs
over the spring retainers of the upper jaws and fit the upper
jaw to the lower jaw. While holding the jaws together position
them onto the drum and align the holes in the jaws to the
holes in the drum. Re-attach the jaws to the drum with the
cap screws. The hole in the drum for attachment of the upper
jaw has a small set screw inserted into the hole from the back
side of the drum. This set screw was adjusted at the factory
to provide the proper engagement of the upper jaw screw
with the drum. When tightened the upper jaw should slide
