STEP1、MOVINGTHEMACHINE
The machine should be moved to the work site with a fork lifter. Make sure that the loading
capacity of the fork lifter is adequate for the machine's weight. The fork must protrude from
the far side of the machine bottom when moving. Pay attention to the machine balance
while it is being moved, and make sure it does not strike the floor when being place at the
work site.

STEP2、MACHINEINSTALLATION
Once the machine has been moved to the work site, the machine installation must be
performed. The machine should be placed on the ground but not necessary to bolt the
machine to the floor. The machine comes furnished with 4 or 6 steel leveling plates which
should be placed under the leveling screws before proper leveling adjustment can take place.
Place a precision level gauge on the conveyor table to check leveling. There are three labels
show you where to take a measurement. Machine leveling can be adjusted by turning the
leveling screws located at each comer of the base until proper leveling is obtained.

STEP5、CONVEYORBELTHYDRAULICDRIVINGSYSTEM
The hydraulic driving system for the conveyor belt should be filled with circulating oil ISO-R68
either 140 liters. The ends of the two hydraulic hoses are connected to the oil outlet and
inlet port.
The other ends are connected to the outlet and inlet ports of the hydraulic motor. Once all
hoses are
securely connected, the hydraulic pump motor can be connected to the power source wires.
The power source wires of the motor are located at the bottom right of the back of the
machine.
1. If the power phase wires are incorrectly connected, then the conveyor belt will not start.
In this event, it is necessary to change the phase connection points of the power source
wires.
2. If the conveyor belt is running but in the wrong direction, exchanging the connection
positions of the hydraulic hoses.
3. The maximum allow operating pressure is 50kg. In the case of over-pressure, lower the
table may reduce the pressure.
※This system is optional equipment.

STEP、6AIRCIRCUITCONNECTION
The air circuit connector is on the filter/regulator unit which is located below the control
panel.Connect the air source (size: 5/16”) connector to the air supply with the flexible hose.
The working pressure of the machine can be adjusted from the pressure regulator：
1. Set the pressure by lifting the adjustment knob and rotating it clockwise for increased
pressure,
Push the knob down to lock it in place once the correct pressure had been set.
2. The normal working air pressure should be set in between 5~6kg/cm². All horse will
automatically have stopped when the air pressure is under 4 kg/cm².
STEP7、DUSTCOLLECTIONEQUIPMENT
Each sanding head is provided with a dust hood with an outlet diameter of 5”. Connect each
dust hood to the dust collector with a flexible hose. Make sure the dust collector has a
sufficient capacity for the machine or the dust may cause bad sanding performance.
