Belt tension and side-drift adjustment.
Belt tension must be adjusted whenever the machine was first installed or moved. Otherwise, it may cause slipping or damage of belt or
worn-down and breakage of other parts. Belt adjustment consists of belt tension adjustment and level adjustment.
Note
:
Turn the belt adjustment screw-heads in end-cover using 8 mm hexagon wrench to adjust the belt as shown in the above
Adjustment with T-Wrench and movement change of belt and roller
Adjustment of Tension
It is adjustment of distance between front and back rollers to obtain
optimal tension of the belt which is necessary to prevent slipping of
the belt during running..
1 : Turn the power on.
2 : Operate the machine at 4km/h.
3 : Holding the handgrip, push the belt with foot to the opposite
direction of running. If the belt momentarily stops (slips), then
adjustment is necessary.
4 : Adjust belt tension turning the adjustment screws left or right
using hexagon wrench. Repeat the process until no slippage
occurs.
Adjustment of Side-drifting
After the adjustment of belt tension, adjust side-drifting as follows
1 : Increase the belt speed to 10 km/h.
2 : Adjust belt balance using 8mm hexagon wrench while visually
checking the belt for side-drifting.
3 : If no sign of side-drifting shows after 5 minutes, then the balance
of belt has been achieved. If side-drifting occurs within 5 minutes,
repeat the process until balance is achieved.
4 : If necessary, talce out the motor and adjust belt balmce by using
8mm L-wrench as shown in the picture

Do not turn the wrench without checking the change in belt
movement. Too much turning will push the belt to one side and
can damage it. It is recommended to turn the wrench by 1/4 or
by 1/8 revolution at a time for precise ad justment.
