Introduction
The STAC M 500 plow was specially designed to break compacted
layers with safety, agility and reduced maintenance.
Manufactured with 5 and 7 shanks, this plow has a modern
structure with high resistance. The working depth is determined
by the cylinder stops installed on the hydraulic cylinder rods.
This plow model can be optionally supplied with:
•Disc blade: perfect to cut straw;
•Cage roller: Break the clods and facilitates the job of other
equipments, leaving a pre-leveled soil.

for the best performance of this plow. The operator must carefully
read the entire manual before working with the equipment. Also,
read and understand the safety recommendations.
For any further clarification or in the event of technical
problems that may arise during the service, consult your dealer
and the Technical Support department of the factory. They can
ensure the fully functioning of your Civemasa plow.

Transportation over truck or trailer
To the operator
Civemasa does not advise the equipment traffic on highways, because this
practice involves serious security risks in addition to being prohibited by the
current existing traffic law. The transportation for long distances should be
done on truck, trailer or other by following these safety guidelines:
• Use adequate ramps to load or unload the equipment. Do not make the loading
on ditch banks, it can cause a serious accident.
• When lifting with a hoist, use the appropriate points for lifting.
• Underpin the equipment appropriately.
• Fasten the moving parts that may get loose and cause accidents.
• Use chock blocks and safety chains to secure the equipment to the truck or
trailer during the transport.
• Make sure the SMV (Slow Moving Vehicle) sign, and all the lights and reflectors
that are required by the local highway and transport autorithies are in place,
are clean and can be seen clearly by all overtaking and oncoming traffic.
• After 8 to 10 km transporting, please inspect the load condition. Repeat this
procedure every 80 to 100 km. Give more attention when transporting the
equipment on rough roads, slopes and other adverse conditions.
• Always be careful with the load height, especially when passing under electrical
power lines, bridges and others.
• Check all laws and regulations regarding the height limits and load width while
transporting the equipment to the truck or trailer. If necessary use banners,
lights and other devices in order to give adequate warning to the other drivers.

To facilitate transportation, the plow leaves the factory unassembled. To start assembling,
choose a flat and clean place and follow the steps below:
Separate the parts to facilitate identification and check them
according to the list that can be found
inside the box.
Place the frame over four trestles
with at least 850 mm of height each.
Assemble the drawbar (A) to the frame using pins (B) and cotter pins. Then, couple
the extensor arm (C) to the frame and drawbar using pins (D) and cotter pins.

IMPORTANT
• After assembling the equipment, activate the hydraulic circuit so just one
side of the equipment will lift up. Activate some more until the equipment is
leveled.
• This procedure is executed just once so the hydraulic circuit is filled
completely, thus the other activations will carry out the operation with a
leveled equipment.
• Frequently observe the general state of the connectors, hoses and
cylinders to see if there is not physical defect, wear or leakages.
• If necessary, use thread sealing tape to couple the hoses and the
'male' part of the quick couplers.

ATTENTION
The following instructions must be carefully observed in order to get the best work
performance.
The addition of ballast water in the tires and a set of weights on the front part and rear
wheels of the tractor are the most used ways to increase the soil traction and give greater
stability to the tractor. Check if the tractor is in good condition before using it.
Check the condition of all parts, retightening nuts and bolts, especially from the disc
gangs. These will damage the axle and other components when working loose.
Check the tires inflation and keep the same pressure on all of them.
Lubricate all grease fittings appropriately. (See 'lubrication' instructions).
Couple the equipment to the tractor by hitching the drawbar (A) to the hitch bar (B)
using a pin (C) and connect the hydraulic cylinder hoses (D) to the tractor remote control
couplers.
If necessary, use the extensor arm (E) to facilitate hitching.
• The tractor drawbar must remain fixed and centralized.
• The hitch pin (C) is not included with some equipment models.
• During transportation, the hydraulic lower arms must remain lifted.

Important recommendations
AA
To couple the hydraulic cylinder hoses (D) to the tractor remote control couplers, shut
down the tractor engine, relieve the control valve pressure by activating the lever a couple
of times and check if the quick couplers are clean.
Before starting the subsoiling job, inspect the plow and retighten all bolts and nuts;
also check the conditions of all pins and cotter pins to avoid future damages. Repeat this
operation after the first day of work.
The tractor drawbar must remain fixed and centralized.
It is really important to check the tires inflation and to keep the same pressure on both
of them.
Before connecting the equipment hoses to the tractor, check if the hose is pressurized.
If the answer is positive, the operator will not be able to connect the male part to the female
one - and forcing this operation may lead to severe damages to the eye and skin as the
fluid may escape. To remove the pressure on the tip of the hose, press the male coupling
against a non-metallic surface to move the retention valve, until there is no oil leakage
anymore.
Activate the control valve lever and check for any leaks on the terminals and on the
quick couplers.
To transport the equipment, it is necessary to use the transport locks which are coupled
to the hydraulic cylinder rods. When they are not being used, the safety locks must remain
fixed to the equipment on their appropriate place.
