Melco Fast Clamp Adjustment

When attaching the Melco Fast Clamp onto the machine's X Carriage for the first time, verification is required that
the top surfaces of the Lower Clamp Arms are not located too high in relation to the Needle Plate. If the Clamp Arm
Assemblies are set too high negative results related to embroidery quality can be expected due to flagging of the
embroidery media during the embroidery process.
Clamp Arm Assembly Height Setup
STEP 1: Checking Clamp Arm Assembly Height
With the Upper Clamp Arms in the open position, place a ruler or similar
rigid and straight device across the Lower Clamp Arms to check the gap
between the top side of the Lower Clamp Arms and the top side of the
Needle Plate (see images).
 If there is a gap between the ruler and the Needle Plate, the Clamp
Arm Assemblies need to be lowered.
 It is acceptable if the Lower Clamp Arms are slightly lower than the
Needle Plate.
 In case the Lower Clamp Arms are positioned significantly lower than
the top side of the Needle Plate (more than 2mm (0.08")), the Clamp
Arm Assemblies need to be raised.
The Melco Fast Clamp is assembled with one (1) set of Spacer Plates.
There are two (2) additional separate Spacer Plates supplied with the Melco
Fast Clamp Assembly.
 If there is a gap between the ruler and the Needle Plate, one
additional Spacer Plate needs to be added to the each of the Clamp
Arm Assemblies to lower the Clamp Arm Assemblies.
 If the Lower Clamp Arms are positioned significantly lower than the top
side of the Needle Plate, more than 2mm (0.08"), the Spacer Plates built
into the Clamp Arm Assemblies need to be removed.
STEP 2: Adding or Removing Spacer Plates
1. Loosen the two (2) Hex Head Screws (#1 in image below). The Lower Clamp Assembly will detach from the
Sliding Block.
2. Insert or remove one (1) Spacer Plate (#2 in image below) between the Lower Clamp Arm Assembly and the
Sliding Block.
3. Re-insert the two (2) Hex Head Screws (#1 in image below) and securely tighten both.
4. Repeat for the other Clamp Arm Assembly
