NOTE
1. OIL FILLING
NOTE: Push the press lever "PUSH" to adjust
the stitch length. It's designed to prevent knob form rotating at GC6-9.
15. ADJUST THE SYNCHRONIZATION OF THE NEEDLE MOTION WITH FEED MOTION
Before putting a new machine into operation,
remove the plugs (A) at the top of the arm and replenish
sufficient amount of oil, then lift the presser foot and run
the machine at a low speed of 2000 rpm to check oil
distributing condition through oil check window. When
lubricating is normal, the machine runs at in at this speed
for 30 minutes, then increase the running speed
gradually. After one month run-in operation, the machine
can be run at the Max speed under normal working
2. ROTATING HOOK OIL AMOUNT ADJUSTMENT
3. OIL PUMP ADJUSTMENT
(1) The oil amount in the oil reservoir is controlled
through the reference marks A and B shown in Fig2. The
max. oil amount level will be under the mark A indicates the max. oil amount level. If the oil level is under
the mark B, replenish the oil reservoir with oil in time.
(2) When filling oil, loosen the oil draining screw (c),
drain off the remaining oil in the oil reservoir completely,
clean the oil reservoir and tighten the oil draining screw (c),
then fill the oil reservoir with fresh oil.
Adjust the oil amount of the rotating hook by
turning the oil amount adjusting screw (A). Turn the
screw(A) clockwise (in the "+" direction) to
increase the oil amount; turn it counter-clockwise
(in the "-" direction) to decrease the oil amount.

4. NEEDLE INSTALLATION
Turning the balance wheel to lift the needle bar to
the upper end and of its stroke. Loosen the needle
clamp screw while keeping the long groove of the
needle leftward, fully insert the needle shank up to
the bottom of the needle socket, then tighten the
needle clamp screw.
5. CONNECTION OF THE CLUTCH-LEVER WITH THE PEDAL
(1) The optimum tilt angle of pedal is
approximately 15 deg.
(2) Adjust the clutch so that the clutch lever (c)
align with the draw bar (B) as shown in Fig. 6
(3) The machine pulley should rotate counter
clockwise when viewed from the outside of it. The
rotating direction of motor pulley can be reversed by
turning the plug of the motor at 180 deg.
(4) Adjust the tension of O-Belt (F) by moving
the motor up and down, the proper tension of the
O-belt is a slack of 10-20 mm when the belt is
depressed at the center of the belt by finger.
6. BELT COVER INSTALLATION
7. ADJUST THE OPENING TIME OF THE TENSION DISCS
Install the belt cover for the sake of safety.
Install belt cover (C) to arm with screw(A) and screw (B),
and install belt cover(E) on board with screw(D).
Note: there aren't screw (A) and screw holes on belt
cover in GC6-9.
Within the presser foot lift range of
the tension discs can be adjusted as follows:
(1) Remove the rubber plug (A) from the
arm and Loosen the screw (A) of the knee lift level
(left)
(2) Move the tension releasing lever to the
earlier opening or rightward for later opening. It will
facilitate the adjustment if put a block under the
presser foot lift.

Pressure of the presser foot is adjusted in
accordance with thickness of materials to be sewn.
First loosen the lock nut (A), for heavy materials,
turn the pressure regulating thumb screw as shown
in Fig. 11 (a) to increase the pressure while for light
materials, turn the pressure regulating thumb screw
as shown in Fig. 11(b) to decrease the pressure,
the tighten lock nut (A).
