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.
