ASSEMBLY
Due to packaging requirements, your belt sander is partly assembled. Please do not
operate this belt sander before it is completely assembled and all bolts are completely
secured. The number shown in bracket is the part number.
Please refer to the assembly diagram A (or B if needed) to assembly the belt sander. The
following are the steps to complete the assembly of the belt sander.
Step 1: Assemble the stand. Please note that the short bars(#95) are always ride on the
long bars(96#) and the bolt holes are always aligned.
Step 2: Put the main assembly on the stand and fix it on the stand with 4 bolts(#92) and 4
screws(93).
Step 3: Attach the long (front) table to the Main assembly. Insert the U-bar(#85) into the
two slot on the supporting frame of the table. Then insert the U-bar with the table into the
slots on the main assembly. Both end of the U-bar must be penetrated through the two
holes behind the main assembly. Insert a pin(#84) into the pin hole at each end of the
U-bar.
Step 4: Attach the short(side) table to the Main assembly with the four bolts(#7) and four

screws(#62). Then attach the pointer(#66). The degree label is properly turned in factory,
when the table is at its level position, the pointer must be pointing at 90 degree. If not,
please loose the four bolts(#7) and adjust it.
CHANGING SANDING BELT
To change sanding belt, open the cover (#58),then pull off the bar(#35), loosen the
bolt(#45) that on the dust hood(#44). Turn the tension handle to left(anticlockwise). Take
out the sanding belt and replace with a new one. Recover all steps previously done.
Because the size of a new sanding belt is slightly different from the old one, it may affect
the alignment.
Proper tracking is achieved when drive roller and idler roller are aligned to fit the sander
belt. The knob (#14) is used to tilt the idler roller.
POWER CONNECTIONS
ALLL POWER CONNECTIONS MUST BE DONE BY QUALIFIED EELCTRICIAN. A separate
electrical circuit should be used for the sander. This circuit should not be less that No.12
wire and should be protected with a 15 amperes time lag fuse if three phase current is
applied or a 20 Amperes time lag fuse if single phase current is applied. Before
connecting the motor to the power line, be sure that the electric current is of the same
characteristics as stamped on motor nameplate. All line connections should make good
contact.
If extension cord is allowed according to local codes and ordinances. USE PROPER
EXTENSION CORD. Make sure your extension cord is in good condition. When using an
extension cord, be sure to use heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. The correct cord size to be used depends on cord length and nameplate
ampere rating. If in doubt, consult qualified electric service personnel.
NOTE: RUNNING ON LOWER VOLTAGE OR HIGHER VOLTAGE THAN THE VOLTAGE
THAT THE MOTOR WAS DESIGNED WILL DAMADE THE MOTOR.
DUST COLLECTION
For health and safety reason, using a dust collection system while working with this belt
sander is recommended.
