LUBRICATION AND MAINTENANCE

•Check daily for any unsafe conditions and fix immediately.

•Check that all nuts and bolts are properly tightened.

•On a weekly basis clean the machine and the area around it.

•Lubricate threaded components and sliding devices.

•Apply rust inhibitive lubricant to all non-painted surfaces.

Note: Proper maintenance can increase the life expectancy of your machine.

Machine Lubrication

The main lubricating positions of machine:

Cutting Beam roller bearings

Calcium-based grease

2000 hours

Rolling surface of rollers and guides

Calcium-based grease

40-50 hours

Lead screws, chain and guiding groves

Calcium-based grease

40-50 hours

Exposed wear surfaces and bare metal parts

Calcium-based grease

40-50 hours

Blade Changing and Grinding

It is very important to grind the blade edges regularly. Long time use of blade, with no grinding,

will increase the cost of grinding, and shorted the blade life as a whole. Continuous shearing

with blunt cutting edges, will cause the outer crystal grains of the blade to be damaged under

the excessive pressure.

Through the grinding of cutting edges, the outer layer of the damaged crystal grains can be

removed. For this, a schedule for blade edges grinding should be made based upon actual

production material and schedule.

The following schedule for cutting edge grounding is recommended:

•Cutting edge change after 80-100 working hours for blade;

•Cutting edge grounding after 320-400 working hours for blade. There are 4 cutting edges for

the each of blades equipped on the machine.

WARNING:Make sure the electrical disconnect is OFF before working on

the machine.

Maintenance should be performed on a regular basis by qualified personnel.

Always follow proper safety precautions when working on or around any machinery.

•The schedule recommended above is only to be used for the shears put into normal

operation. If the cutting edges of blade are arranged for grinding following the schedule, the

removal quantity of blade would be minimum, and its lifetime be maximum possible.

•After the edge grinding or replacement of blade, the blade clearance has to be re-inspected

and readjusted.

Hydraulic System

•Inspect the oil level of tank regularly. If the oil is below the mid-line of oil level, replenish the

tank immediately.

•The first oil change has to be made after 500 working hours. Afterwards oil change is to be

made regularly whenever the machine has worked for 2000 hours.

•Clean the oil suction filter after the first 40 hours of operation and then follow the hydraulic oil

changing schedule.

•Clean the hydraulic breather cap after the first 40 hours of operation and then follow the

hydraulic oil changing schedule.

•It is recommended not to work below 23°F (-5°C) or above 167°F (75°C). In cases where the

temperature is very low, running the system at idle for several minutes will warm the oil. If

needed, install a heater in the hydraulic system to warm the oil, or a cooler if the temperature

is too high.

Changing Hydraulic Oil

The hydraulic oil is the primary medium for transmitting pressure and also must lubricate the

running parts of the pump.

Cleaning of the oil tank is very important. Proper hydraulic operation depends upon clean

hydraulic oil and a clean hydraulic system.

Important: Used oil products must be disposed of in a proper manner following

your local regulations.

1. Remove the center (and right if desired)

front cover to access the reservoir.

2. Have a container capable of holding at least

30 gal. (114L) available to drain the tank

into.

3. Using the drain plug at the front of the tank

or a siphon pump through the top of the

tank, empty the tank into the container and

recycle according to local standards.

4. Remove the top cover and clean the hydraulic tank and re-install the top cover.

5. Use hydraulic oil #68 SHELL BRAND or an equivalent with similar specifications to fill the

hydraulic tank until it reaches the midpoint on the sight gauge.

6. Keep hydraulic reservoir filled to 90% of capacity.

7. DO NOT rely totally on the oil gauge as they can sometimes

indicate an incorrect level reading. Do a visual inspection with

the oil fill cap removed as well.

8. A shortage of hydraulic oil will cause hydraulic system

breakdown to major mechanical components due to

overheating.

9. Change the hydraulic oil and clean the suction filter after the first

500 hours of operation. Thereafter the hydraulic oil and filter

should be changed at 2000 hours or annually.

Hydraulic Pressure Filling the Accumulator

Note: This operation requires two people to be able to reach switches and valve at

the same time.

1. Open the shutoff needle valve #8 to allow

pressure to the pressure gauge.

2. IF THE SHEARING RAM IS NOT ALL THE

WAY AT THE BOTTOM OF ITS TRAVEL,

OPENING THE BALL VAVLE #7 WILL

CAUSE THE RAM TO FALL. Open the

shutoff ball valve #7 slowly allowing the ram

to lower to the bottom position.

3. Start the pump and place the stroke key

switch in the left jog stroke position.

4. Place the accumulator switch in the right “1”

position. This will energize the YA1 and YA2

valve.

5. Adjust the relief valve #16, until the oil pressure of accumulator is at 11MPa, this is the P2

value as shown on the hydraulic diagram.

6. Close the shutoff ball valve #7. Then turn the accumulator switch to the “0” position. The

cutting beam will raise by the pressurized oil from the accumulator.

7. Close the shutoff needle valve #8. This will prevent the pressure gauge from feeling any

pressure spikes during normal operation.

NOTICE: This is not a common function. The accumulator has been charged from the

factory and will not require charging unless someone has tempered with or inadvertently

actuated the accumulator hydraulic circuit ball valve. The accumulator will only require

hydraulic pressure filling if the hydraulic pressure gauge is below 8MPa AND the shearing

ram will not lift and hold at the full up position.
