INSTRUCTION MANUAL
Column Press with Hand Pump
TYPE OF INSPECTION
FREQUENT: a visual inspection carried out before and after each operation.
PERIODIC: a thorough examination of the equipment, both externally and internally. The equipment is labelled with the inspection date and the date is logged in a
register.
PARTS TO INSPECT
In a FREQUENT INSPECTION, check for:
•
Piston wear
•
Signs of corrosion
•
Wear or damage to the cylinder or pump
•
Cracks, dents or any other damage to the frame, cylinder attachments, work table and its supports
•
Oil leaks
•
Loose or damage screws or joints
•
Damaged or incorrectly assembled accessories
In a PERIODIC INSPECTION, check for the same problems as in a frequent inspection but in addition, the hydraulic equipment should be disassembled and cleaned
by an authorized service dealer so that it may be examined internally.
Periodically clean and relubricate the press’s moving parts, such as the piston, winch, pumping mechanism, etc. This is especially important when working in salty or
humid environments.
Hydraulics equipment, which is subject to the very severe environmental conditions mentioned, previously should be cleaned and relubricated after each use.
To clean the hydraulic equipment, begin by removing the pump’s oil reservoir plug and draining al the oil. Fill reservoir with kerosene and thoroughly circulate it
thorough the hydraulic equipment. After completely purging the kerosene out of the hydraulic circuit, align the pump vertically with the head down and fill the
reservoir with the new hydraulic oil until the oil level rises to the orifice
6. PROBLEMS, DAMAGES AND SOLUTIONS.
6. PROBLEMS
CAUSES
SOLUTIONS
1. The piston does not advance.
- The pump’s relief valve is open.
1. Close the relief valve.
- Air is trapped in the hydraulic circuit.
2. Open the pump’s relief valve, align the pump vertically
with its head down, and pump the oil several times so that the
air is purged out of the hydraulic circuit.
- No oil in the reservoir.
3. With the piston fully retracted, align the pump vertically
with its head down, remove the oil reservoir plug and fill the
oil reservoir until the oil level reaches the plug’s orifice.
- Dirt has accumulated in the hydraulic circuit.
4. Clean the hydraulic circuit with kerosene as described
previously. If the problem persists, take the press to an
authorized service dealer.
- Worn or damaged check valve.
5. Take the press to an authorized service dealer.
- Improperly connected hydraulic line
6. With the piston fully retracted, ensure that the hydraulic line
is properly connected to the pump and cylinder.
2. The piston advances in spurts.
- Air is entrapped in the hydraulic circuit.
See Solution 2.
- Deformed piston.
See Solution 5.
3. The piston will not fully extend.
- Low oil level.
See Solution 3.
- Deformed piston.
See Solution 5.
4. the piston advances very slowly.
- Air is entrapped in the hydraulic circuit.
See Solution 2.
- Dirt has accumulated in the hydraulic circuit.
See Solution 4.
- Worn or damaged check valve.
See Solution 5.
- Improperly connected hydraulic line
See Solution 6.
