(2) Leveling: 

The production accuracy of all precision machinery depends on the accuracy which the machine is 
installed. Manufacturing tolerance of the machine can only be guaranteed if the machine is firmly and 
properly installed . Once the machine is lowered on the prepared foundation. Machinist levels should be 
Used alternately on the vise slide plates and the work feed table , and adjust the left-and-right and 
fore-and-aft level of the machine with leveling bolt . 
The fore-and-aft level should be adjusted so that the level of the rear end is approximately 10 mm (3/8" -   
1/2") higher than the level of the front end , to provide proper return of the cutting fluid , and easy 
operation of car feeding . 
The left-and-right level should be adjusted so that the level of the left end is approximately 3 mm (1/8")   
higher than the level of the right end , to provide proper return of the cutting fluid , After the proper   
leveling position has been obtained anchor the machine with anchor bolts . 

CAUTION 

: All leveling bolts should support the weight of the machine evenly . 

Leveling as fig 5 below : 

 

FIG 5 

  (3) Cleaning and oiling : 

After the machine has been placed in position , thoroughly remove its rust preventive coating using a   
suitable cleaning solvent and then apply a coat of machine oil . To clean the machine , Kerosene is   
preferable to gasoline . It does not evaporate and level dried slushy compound on finished surfaces. 
Rags are better than waste as they leave no lint or strings. The machine as received by you. has been 
completely drained of all oil. Before any attempt is made to run it . Before any motor connections are   
made .... every detail of the following oiling instruction must be complied with. Refer to the oiling chart in 
chapter 7. Especially, don't forget to fill up the cutting fluid mixture. Usually, the ratio of cutting fluid to   
water should be 1:30 - 1:50. Check the sight gauge to ascertain the fluid level in the tank every day. 
Transmission gear box, bar feed gear box, hydraulic oil tank should to topped up monthly. Oil levels 
should  
be strictly observed, for it is of primary importance for proper operation and long life. 
 

(4) Power Source Connection : 

A. Power Source - This machine is equipped with 

7.5HP main motor

 and 

2HP

 

hydraulic motor

, and 

1/8HP

 

coolant pump

. Connect the power supply cable to the circuit breaker (N.F.B.) terminals.   

The power supply to your machine should agree with the wring voltage that is indicated on the label 
attached to the electrical enclosure and main motor. 

B. Earth - Be sure to connect the earth cable to the earth terminal. 
C. Starting - After making the necessary wiring connections, turn the power switch on the control panel 
clockwise to turn power on, depress the vise limit switch (if necessary, e.g. if there is no stock bar clamped 
in the vise) and push the button to see if the saw head moves upward. 
If the saw head does not rise , the hydraulic pump motor is rotating in the wrong direction. 
If the motor runs in the wrong direction, turn off the power switch and disconnect the power supply cable, 
Then interchange any two phase connections.
