4.1. Failed oil tank gasket.
Every Comtec press is built with a self-adhesive gasket strip between the top of the oil
reservoir and the underside of the machine’s cover. If this gasket strip is damaged or
wears out, oil will “spill” over the side of the machine every time the machine is
moved. This oil will appear to leak down the sides of the machine. A small amount of
oil leaking down the side of the machine should not affect the machine’s performance.
If this leaking continues to occur, however, it can reduce the level of hydraulic oil in
the machine to a point that will affect machine performance.
4.2. Failing hydraulic cylinder seal.
Oil that leaks from the point where the hydraulic piston comes out of the cover of the
machine is a sign that the hydraulic cylinder seals have failed. Failed hydraulic cylinder
seals will affect machine performance and cause uneven and inconsistent crust
formation. Contact Comtec to see if a cylinder seal repair kit is available for your
machine.
4.3. Broken hydraulic line.
If your Comtec Model 1100 or Model 2200 is pressing incorrectly or inconsistently,
there may be a leak in the hydraulic system under the machine cover. Carefully inspect
the hydraulic tubing for cracks or gaps.
4.4. Failed pump.
Poor pressing performance can be caused by a failed hydraulic pump. A failing pump
can sometime be diagnosed by a dark metallic sediment that continues to appear in the
bottom of the hydraulic reservoir. Contact Comtec to see if a replacement pump is
available for your machine.
4.5. Failed hydraulic valve
When the machine’s hydraulic control valve fails, the machine’s travel plate will not
move when both operating handles are activated. This is not a common problem but
can occur on older machines. Contact Comtec to see if a replacement valve is available
for your machine.
4.6. Hydraulic settings have been changed from factory standards
The hydraulic system on Comtec machines is designed and manufactured to not only
be reliable, durable and safe to use. The hydraulic should NEVER be modified or
adjusted by the customer or maintenance personnel without Comtec’s approval.
Adjusting or modifying the hydraulic system unsafe and will cause inconsistent and
unpredictable functioning of the machine.
