Installation
2.1 Machine Lifting
There are 2 hooks on each side of the machine. As the machine has a high center of gravity, the front side is heavier than the backside. Be cautious about balance of the machine, so it will not fall over when you are transporting it with the steel pipe. Lifting fork of the forklift must be in the direction front of the machine. (Refer to figure 1)

2.2 Foundation Installation
The cement foundation of the machine must be prepared 10 days before the machine installation. The hole dimension is 100*100*400mm. Distance between holes is shown in chart 1 and figure 2 in accordance with type of the machine. Placing the machine on the foundation, use hole-in anchor bolts for installation before mortar setting. Place a foundation plate (refer to figure 3) under each of the jack bolts to level the machine with the gradient of the table within 1000 : 0.20 mm.

2.3 Cleaning
Clean the rust-preventive grease on following parts:
2.3.1 Piston rod
2.3.2 Grating gauge guide
2.3.3 Backgauge guide ways, ballscrews and beam surface.
2.3.4 Ram guide
2.3.5 Worktable, die holders and dies.
Notes: Spirit and kerosene oil are allowed for cleaning except for scouring agent with dissolving power.
2.4 Leveling
Adjust the jack bolts for the machine leveling.
Putting the machine in a horizontal position in the front-rear direction, adjust the jack bolts to measure the gradient of the table with the spirit level at both ends of the table. Put the machine in a horizontal position in the left-right direction with the level at the table center.
Repeat the above steps after the electrical connection work. Tighten the nut of the jack bolts and the nut of the anchor bolts respectively.
Check and adjust the gradient of the machine again after 30-50 hours operation for the soil quality and bearing capacity.
Notes: Keep the machine 5 mm higher than the foundation.
2.5 Electrical Connection
Notes:
Power supply should meet requirement of the machine specifications. (Refer to Electrical Circuit Diagram)  
1. Only the trained and authorized personnel can carry out electrical connection in accordance with Electrical Circuit Diagram. Cable inlet is at the bottom of the electrical cabinet. (Refer to figure 5.)
2. After the main switch is connected (phase conductors L1, L2, L3), starting the oil pump motor only for 2-3 seconds, and check if fan rotation of the oil pump motor is in the direction of the indicated arrow. Exchange the two-phase conductors if not.
