3 Structure
This machine is specially designed with the structure of plate combined bench type. It is very
convenient and reliable in usage and maintenance. It is mainly made up of front and back
bench, right and left bearing base，right and left wall board, press planing table, sawing table,
arbor, motor and driving system. The machine can be accommodated to either one phase or
three phase motor (1.5kW／1.1kW)
The main driving is by V-belt as chain and gear ways. The feeding of press planing is
automatically. The anti-kickback jaw guarantee the security of operation. The cutter head is
installed on the milling arbor. The milling protective device guarantee the security of milling
operation.
4 Carriage & Installment
During carriage, using lifting hook (Fig.2). To keep the machine balance, handle carefully.
Keep the machine in a wide and arid place. Fix the machine with ground bolt (see Fig.3) On
behalf of carriage, some of the parts are packed with small packing box. In this case, the
customer must mount the dismounted parts in accordance with the stages and means
showed below.
As Fig.15 showing to mount the box base.
As Fig.4 showing, mount milling part first. Fix supporter 35 on left wallboard 36 with bolt 34.
Let milling table 7 parallel with surface planing table, then insert column guide 23 into the
hole of milling table 7. Screw the bolt 28 tightly and then mount presser 11 and push presser

●Keep the blade in the middle, put the ruler 1 on the back bench 2, rotate the arbor 6, adjust
the length of the knives above the surface of the bench until it can reach the ruler1 on the
back bench 2. Adjust the blade and make it parallel with the back bench or 0.05mm higher
than the back bench on basis of back bench 2. Then lock the three screws 5 of tool presser 4.
Turn the middle one first, then the both sides. Repeat the operation and mount the three
knives.
Caution:
●Never mix knives of different types and series.
●Sharpen the knives in a way that the sharpening height and the angle (38°～42°) are
always the same for each series.
●The knives can be sharpened up to a minimum height of 21mm (original dimensions 260×
30×3mm).
7.2 Surface planing (Fig.9)
Surface planing occurs with one or more passes to straighten the first and the second side of
a rough piece of wood. After obtaining the complete flatness on the first side, pass on to
planing the second side at 90° to the previous one. Let the first side against the guide 7 and
the second side against the infeed table 4, put the left hand in front of the right one, push the
wood lightly. After the wood passing guard 3. Place left hand forward to press the wood on
outtable. Push the wood by right hand continually. Never put hand under guard 3.
You should move the guide to the right side of the table 4 and lock it by bar 6 make full use of
bridge guard 3.
Caution: Let the smooth surface of guide 7 face leftwards (Fig.9) dismount sawblade. Drill bit
cutterpan and milling hood. Mount saw cover and arbor cover. Let button 1 in the position of
R (Fig.14).
●For planing operations on the wide side with a height of up to 60mm. Adjust guard 3
laterally against guide 7 and rest it on the workpiece.
