(15) MAINTAIN TOOLS IN TOP CONDITION.
Keep tools sharp and clean for best and safest performance. Follow
instructions for lubricating accessories.
(16) DISCONNECT TOOL before servicing and when changing accessories
such as blades, bits, cutters etc.
(17) USE RECOMMENDED ACCESSORIES.
Consult the owner's manual for recommended. The use of improper
accessories may cause hazards.
(18) AVOIDE ACCIDENTAL STARTING
Make sure witch is in “OFF” position before plugging in power cord.
(19) NEVER STAND ON TOOL
Serious injury could occur if the tool is tipped or if the cutting tool is
accidentally contacted.
(20) CHECK DAMAGED PARTS
Before further use of the tool, a guard or other part that is damaged
should be carefully checked to ensure that it will operate properly and
perform its intended function-check for alignment of moving parts,
breakage of parts, mounting,. and any other conditions that may affect
its operation. A guard or other part that is damaged should be
properly pre-paired or replaced.
(21) DIRECTION OF FEED
Feed work into tool bit against the direction of moving of the tool bit
only.
(22) NEVER LEAVE TOOL RUNNING UNATTENDED. PUSH POWER
STOP.
Don’t leave tool until it comes to a complete stop.
(23) DRUGS, ALCOHOL, MEDICATION.
Do not operate tool while under the influence of drug, alcohol or any
medication.

(24) MAKE SURE TOOL IS DISCOUNNECTED FROM POWER
SUPPLY while motor is being mounted, connected or reconnected.
1-2. ADDITIONAL SAFETY RULES FOR SLOTTER
(1) BE SURE cutting tool is securely locked in the chuck.
(2) BE SURE chuck key is removed from the chuck before turning on
power.
(3) ADJUST the table or depth stop to avoid cutting into the table.
(4) SHUT OFF the power, remove the cutting tool, and clean the table
before leaving the machine.
(5) CAUTION. When pratical, use clamps or a chuck to secure workpiece
to keep the workpiece from moving with the cutting tool.

3. UNIT AND INSTALLATION
4-1. TRANSPORT INSTRUCTION AND SAFETY:
(1) For the safety transport of the machine. The lifting hooks (∮33MM ) is
provided with each machine. And the hool on the machine top are
pre-installated ex work for this purpose.
(2) Use belts or tables going through hooks as shown in ligure to transport the
machine. Always keep the balance of machine during transport.
(3) Be sure to tighten the lifting hook.
(4) To transport the machine by forklift, be sure to tighten four holes on the
pallet.
4-2. The machine is to be installed on the solid level base of cement concret. It
is essential to test the accuracy by the water level so that it may no affect
the working precision.
4-3. Water level method:
In order to upkeep the machine’s accuracy, the water level testing must be
prudently carried out. Firstly wipe the table surface until it is perfectly
clean then place the tester onto the central part of the work table. The is
to check if every part of the table is in perfect leveling.
4-4. Power source connection:
There are wires behind the machine body to be connected with the power
source. The giant gear should be turhedd according to the allowed
direction for accuracy.

3. Preliminary Work Before start slotting process
Before start slotting edit, operator need to do following work:
①. install the workpiece well
②. Install slotting tool well
③. Adjust suitable stroke length
④. Adjust the suitable slotting top point and bottom point range
⑤. Adjust the cutter lip parallel with X axis travel or two side of cutter surface
parallel with Y axis
⑥. Measuring the cutter center and set the cutter center at workpiece center point
X0, Y0.
⑦. Test cutting to get the first slotting point and set 0 point at graduation scale
ring.
⑧. Select the suitable slotting speed in advance before start slotting.
4. How to adjust slotting stroke length
Before start slotting process, operator must adjust suitable stroke length according
keyway length, usually the machine stroke length must longer at least 30 mm (25mm
at top position + 5mm at bottom position), but if machine stroke length is not longer
100 mm than workpiece keyway length, operator no need to often adjust stroke length
every time.

13
How to adjust the stroke length
一、 The stroke length means the distance between Ram at top point (Dt) and Ram
at bottom
point (Db). (Stroke = Dt - Db)
二、 The stroke is adjustable, Each model minimum stroke and maximum stroke
are as
following table
Stroke
Model
Minimum stroke Maximum stroke
200 60 200
300 75 300
350 75 350
三、 The stroke adjustment procedure are as below:
A: Turn the connecting position between driving wheel and linking road at side-door
location.
B: Loosen the clamping nut (N)
C: Use stroke adjusting handle (H) to move the Radius (R) location for different stroke
length
requirement, The stroke = R x 2 , Move connecting position into near center, The R
will be
reduced and stroke length will be shorter, Move connecting position far away the
center the R
will be increased and stroke length will be longer.
D: After ajusted the stroke well, tighten the clamping nut (N) well before start running
the Ram.

14
5. The adjust stroke procedure is
(1) Open the side cover (as photo X)
(2) Set operation mould at MPG mold or JOG mold (Manual mold)
(3) Use Ram JOG Button to turn the front linking rod driving wheel to let the
adjusting screw at door direction.
(4) Loose the Hexagon linking rod clamping nut (as photo X)
(5) Use stroke adjusting driving handle (as photo Y) to turn the linking rod
connecting position , Move the linking rod connecting position outside, the stroke
length will be longer, if move the linking rod connecting position inside, the
stroke length will be shorter, operator can adjust the stroke length according to
keyway length requirement.
(6) After finish stroke adjustment, Tighten the linking rod Hexagon clamping nut.
(7) Close the side cover.

6. How to adjust the slotting top point and bottom point range
After adjust the suitable stroke length, operator need to adjust the top point/ button point
running range according to workpiece, clamping device and slotting bar conditions.
Procedure:
1) Loose the Hexagon clamping nut A in the front of ram (Photo A)
2) Turn the square Bolt B (Photo B) to move the clamping block higher or lower to
adjust the slotting top and bottom point, usually operator can switch speed to 0 which
locate at backword of speed 1, the speed 0 mean “disengage”, then operator can move
the ram at bottom position by hand rotating backward flywheel, then stop slotting tool
bottom point lower than keyway width bottom position about 5-10mm, the cutter lip
must over keyway length bottom position at least 3mm. (While adjust the position, it
must under speed engage status)(Refer attached Photo C.D.)
3) After finish slotting top/bottom point range adjustment, Note to tighten the Hexagon
clamping nut A well.

7. Traverse travel manual feed of table:
For each turn of the left handwheel, the table feed range is 4mm (0.2”) and
each scale of the micro indicator ring is 0.02mm (0.001”).
8. Manual longitudinal Feed:
For each turn of the handwheel of the ahead & behind, the table, feed range
is 4mm (0.2”) and each scale of the micro indicator ring is 0.02mm (0.001”).
9. Clearance eliminating mechanism:
The clearance between the right & left screws may be eliminated simply by
turning the worm clockwise by means of M5 hexagonal spanner.

7. HOW TO OPERATE ROTARY TABLE
TURNTABLE LOCKING AND UNLOCKING
LOCKING THE URNTABLE
Must lock the turntable before starting cut Rotate both right and lefts locking
handles 26 clockwise. The clamps 24 will hold fixedlx the turntable.
UNLOCKING THE TURNTABLE
Unlock the turntable when the Swivel both right and left locking handles counter
clockwise. The clamps 24 will release the turntable.
WORM SHAFT DIRECTION ADJUSTMENT
WORMSHAFT DIRECTION ADJUSTMENT
When looseness in the axial direction of the worm shaft has been found adjustment
has be done. Remove the assembly in front of the eccentric housing, and then
tighten the worm shaft nut 13 so that the looseness will be adjusted. Do not
forget to lock set screws after adjustment.

19
WORM GEAR ENGAGEMENT & DISENGEMENT
DISENGAGEMENT
Direct rotating the turntable by hand is performed by first disengaging the worm
shaft from the worm wheel by means of an eccentric device. Loosen the set
screw 31 of the eccentric housing and rotate the eccentric housing by the lever 27
clockwise until the seitch finger touches the stop bin on the cover. Lock the
eccentric housing. The worm gear has completely engaged with the worm wheel.
