Suggestions to solve some working problems of the products Hand grease guns, pneumatic grease guns and battery grease guns (cordless) PROBLEMS | POSSIBLE CAUSE | CORRECTIVE ACTION | The grease gun doesn’t dispense | Air in the cartridge or in the cylinder of the grease gun | Unscrew the cap on the head and let leak | The grease gun for cartridges is locked | The cartridge has been badly fit | Open the head, remove the cartridge and assemble it in the correct way ( follow the direction of the arrow printed on the cartridge) | The grease gun doesn’t work with the cartridge | Type of cartridge is not suit to that grease gun | Unscrew the head, remove the cartridge and check the diameter of the cartridge with the plunger diameter. If this components are not suitable, it is necessary to use a cartridge fit to that grease gun or only loose grease | During the use of the grease gun a part of grease flows behind the plunger | The grease gun is manufactured to be utilized with the cartridge (check the diameter) | To open the head, remove the grease behind the plunger and use the grease gun with the correct cartridge. | The pneumatic grease gun doesn’t dispense grease (no movement of the plunger inside) | Breaking of the spring inside the head | Unscrew the cover of the head and replace the spring | The battery grease gun (cordless) dispense grease (no noise inside) | The battery is discharged (it happens also after a long period of inactivity) | Charge the battery ( it would be better to charge completely the battery and to get it cool before the recharge | The battery grease gun (cordless) doesn’t recharge when it will be fixed on the battery charger | The battery charger and the terminals of the battery could be corroded or dirty | Clean the terminals with a rough cloth | The battery is damaged or it is not rechargeable. | Replace the battery | The battery charger is damaged (it becomes warm and produces a strong noise, or it produces smoke during the charge) | Remove immediately the plug from the socket. Replace the battery charger | The battery grease gun (cordless) doesn’t dispense (low noise, the engine turns empty-handed) Do not insist with the action because it could irreparably damage | Lack of the grease in the tank. | Fill the tank. | The exit hole is obstructed | Clean the exit hole. | The grease come out from the valve of the battery grease gun (cordless) | The exit hole and/or the bearings are obstructed. | Clean the exit hole and also the internal bearings (don’t spoil the safety valve). |
Barrel pumps for grease PROBLEMS | POSSIBLE CAUSE | CORRECTIVE ACTION | The barrel pump doesn’t work ( the lever is locked) | The plunger is locked | Open the pump, unscrewing the nuts, to remove the cover and clean the plunger.

A) and clean filter (part.5 fig. A). Check and move pin (part.3 fig.A); 2) Disassemble distributor body, removing pipe (part.24 fig. B), screws (part.14 fig. B) and check the free movement on the nylon valve. Re-assemble and take care to position the valve into the reversing bush seat (part.22). 3) Remove silencer and increase pressure. | Air leakage from the silencer | 1) Distributor valve worn out; | 1) Unscrew as indicated in the chap. maintenance and check that nylon valve striking surface is neither deformed nor dirty, nor blocked in its movement (part.35) | Air leakage through pumping element | 1) Faulty lip seal (part.18 fig. B) | 1) Change seal. | Motor deceleration while working | 1) Water at air inlet, causing condensing effect. | 1) Fit a filter with condensate separator. | Pump does not stop | 1) Dry running; 2) Ball by-pass (part.11 fig.B) is not closing because of impurities in the grease ; 3) Valve (part.6 fig.B) blocked or ruined. | 1) Check that there is no vacuum near suction pipe (part.4 fig.B). Eventually fit a plate with membrane; 2)The ball is dirty. Pump oil to purge for 10 min.; 3)Unscrew valve body (part.7 fig.B) and check that valve (part.6 fig.B) turns freely around the pin (part.3 fig.B) and that it is turned towards the motor (groove upwards). |
Mechanical flow-meter PROBLEM | POSSIBLE CAUSE | CORRECTIVE ACTION | Leak from the shaft gasket | Damaged gasket | Remove (see section “Gear unit”) and replace the O-ring (pos. “22”) and the bush | Insufficient accuracy | Wrong calibration | Repeat calibration following the instruction in section “Measuring chamber” | Soiled or blocked measuring chamber | Clean the measuring chamber following the instruction in section “Meter unit” | Air in the fluid | Locate and eliminate leaks in inlet lines | Reduced flow rate | Clogged or blocked measuring chamber | Clean the measuring chamber following the instructions in section “Measuring chamber” | Blocked or soiled filter | Clean the filter |

Adjust the voltage and/or use cables of greater cross-section | The suction tubing is resting on the bottom of the tank | Raise the tubing | Increased pump noise | Cavitations occurring | Reduce suction pressure | Irregular functioning of the by-pass | Dispense until the air is purged from the circuit | Air present in the diesel fuel | Verify the suction connections | Leakage from the pump body | Seal damaged | Check and replace the mechanical seal |
Electric pumps 220 Volt (art.229, 700, 705, 815) PROBLEM | POSSIBLE CAUSE | CORRECTIVE ACTION | The motor is not turning | Lack of electric power | Check the electrical connections and the safety systems | Rotor jammed | Check for possible damage or obstruction of the rotating components | The motor protecting thermal switch has tripped | Wait for the motor to cool, verify that it restarts, and research the cause of the overheating | Motor problems | Contact the Service Department | The motor turns slowly when starting | Low voltage in the electric power line | Bring the voltage back within the anticipated limits | Low or no flow rate | Low level in the suction tank | Refill the tank | Foot valve blocked | Clean and/or replace the valve | Filter clogged | Clean the filter | Excessive suction pressure | Lower the pump with respect to the level of the tank or increase the cross-section of the tubing | High loss of head in the circuit (working with the by-pass open) | Use shorter tubing or of greater diameter | By-pass valve blocked | Dismantle the valve, clean and/or replace it | Air entering the pump or the suction tubing | Check the seals of the connections | A narrowing in the suction tubing | Use tubing suitable for working under suction pressure | Low rotation speed | Check the voltage at the pump. Adjust the voltage and/or use cables of greater cross-section | The suction tubing is resting on the bottom of the tank | Raise the tubing | Increased pump noise | Cavitations occurring | Reduce suction pressure | Irregular functioning of the by-pass | Dispense until the air is purged from the circuit | Air present in the diesel fuel | Verify the suction connections | Leakage from the pump body | Seal damaged | Check and replace the mechanical seal |
