2. GENERAL DESCRIPTION
Hand Pumps Series 3415 and 3416 have been designed to be used with Serial 26.
Pumps of sturdy construction and reliability; steel body, hardened and lapped double acting steel piston with pressure gauge
and by-pass valve.
Series 3415 for grease is completed with follower plate, with or without spring and re-filling valve. The level indicating rod is
hooked to the following plate, therefore the height dimensions change from minimum (empty reservoir) to maximum (full
reservoir).
3. PRODUCT – MACHINE IDENTIFICATION
Pump identification label is located on the front side of the grease operating pump and contains pump serial number and details
of its operating parameters.

6. UNPACKING AND INSTALLING THE PUMP
6.1 UNPACKING
Once a suitable location has been found to install the unit remove the pump from the packaging. Check the pump has not been
damaged during transportation or storage. No particular disposal procedures are necessary, however packing should be disposed
of in accordance with regulations that may be in force in your area or state.
6.2 INSTALLING THE PUMP
•Allow sufficient space for the installation, leaving minimum 100 mm (3.9 in.) around the unit.
•In order to avoid unnatural posture for personnel install the machine in a comfortable and easy-to-reach location.
•Do not install the unit in aggressive/explosive/inflammable environments or on vibrating surfaces.
•For the fixing use only the bracket arranged with n°3 holes Ø10.5 mm (0.4 in.).
6.3 HYDRAULI CONNECTIONS
Connect the system to pump outlet thread ¼ BSP.
PUMP BODY
WARNING: At the end of all the connecting operations, make sure that pipes and wires are safe from impacts
and carefully fixed.

7. INSTRUCTIONS FOR USE
7.1 PRELIMINARY CHECKS
-Verify the unit is undamaged.
-Check that the hydraulic connections has been carefully carried out.
-Refill the reservoir with impurity-free lubricant.
7.2 PUMP OPERATION
Operating the pump is very easy: to deliver lubricant simply pull and push completely the hand control lever and then release.
We recommend to carry out some lubrication cycles to discharge air from the system.
8. TROUBLESHOOTING
ANOMALY
CAUSE
SOLUTION
Pump does not deliver
lubricant.
Pump does not deliver
the p
roper quantity of
lubricant.
Pump intakes air because the
reservoir is empty
Refill the reservoir and discharge air form the system.
Loose fittings
Tighten the fittings. Be sure there are no leaks.
Obstructed filter.
Clean or replace the filter
Incompatible lubricant Verify lubricant thickness/viscosity and replace it, if necessary.
Pump does not deliver
lubricant at the proper
pressure
Pompa deteriorata Sostituire pompa
By-pass valve not regulated
properly Regulate the pressure valve (3294002)
9. MAINTENANCE PROCEDURE
The machine does not require any special tool for checking or maintenance tasks. However, it is recommended the use only of
appropriate and in good conditions tooling, protective devices (gloves) and clothing to avoid hazards to equipment or persons.
The machine has been designed and manufactured to require the minimum maintenance:
Keep the unit clean and periodically check the pipe joints to detect possible leaks.
10. DISPOSAL
During maintenance or disposal of the machine care should be taken to properly dispose of environmentally sensitive items.
Refer to local regulations in force in your area.
When disposing of this unit, it is important to ensure that the identification label and all the other relative documents
are also destroyed.

12. HANDLING AND TRANSPORTATION
Prior to shipping, pumps are packed and in cardboard containers. During transportation and storage always maintain the pump
the right way up as indicated on the box.
On receipt check that the packaging has not been damaged and store the pump in a dry place.
Given the low weight and the small dimensions, the pump may be handled without any special lifting apparatus.
13. OPERATING HAZARDS
It is necessary to read and understand the possible hazards and risks involved when using a lubrication pump.
The operator must fully understand the hazards implied in pumping grease under pressure.
Flammability
The lubricant generally used in lubrication systems is not normally flammable. However, it is desirable to avoid contact with
extremely hot substances or naked flames.
Pressure
Prior to any intervention, check the absence of residual pressure in any branch of the lubricant circuit as it may cause oil sprays
when disassembling components or fittings.
Spring
Be careful! Pre-loaded spring in the reservoir.
14. PRECAUTIONS
No particular operating hazards characterize these pumps, except for the following precautions:
•Operator’s contact with lubricant in case of piping breaking/opening or during refill/maintenance. -> Protection
against direct and indirect contact with the fluid must be provided by the user: the operator must be provided with
suitable individual protective clothing and devices.
•Use of incompatible lubricant -> Main incompatible fluids:
⇓
Fluid
Danger
Lubricants containing abrasive components
Premature wear of pump
Lubricants containing silicon
Pump failure
Petrol – solvents – inflammable liquids
Fire – explosion –seal damage
Corrosive products
Pump damage - danger to persons
Water
Pump oxidization
Food Products
