Page 11 3 Safety Regulations Safety Regulations Safety information in this operator's manual This operator's manual contains safety regulations in the categories: DANGER, WARNING, CAUTION, NOTE and COMMENT. These are to be followed in order to reduce the danger of injury, damage to equipment or improper service. This is a safety warning symbol that warns against possible danger of injury.
Page 12 3 Safety Regulations Description and purpose of the machine This machine is a portable power source. The portable generator from PRAMAC consists of a frame, which includes a fuel tank, a gasoline engine, a control panel and an electrical alternator. The control panel contains controls and bushings.
Page 13 3 Safety Regulations Operational safety DANGER Carbon monoxide. The application of a generator in buildings can LEAD TO DEATH WITHIN MINUTES. The exhaust fumes from the generator contain carbon monoxide (CO). This is an invisible odorless poison. If the exhaust fumes of the generator can be smelled, CO is being inhaled.
Page 14 3 Safety Regulations Connection prerequisites The following prerequisites are to be met to connect the generator to the building's mains supply. ▪ The generator must meet the prerequisites with regard to performance, voltage and frequency of the equipment. ▪ The generator must be disconnected from the electric power supply. ▪...
Page 15 3 Safety Regulations ▪ NEVER overload generator. The total amperage of the parts connected to the generator may not exceed the output limit. ▪ NEVER operate the machine in snow, rain or standing water. ▪ NEVER allow untrained personnel to operate or maintain the generator. Familiarize yourself with the operation and shutdown before starting the generator.
Page 16 3 Safety Regulations Safety when using combustion engines WARNING Combustion engines pose a particular danger during operation and when refueling. Failure to follow the warning notices and safety standards can lead to serious injury or death. ➢ Read and always observe the warning notices in the operator's manual of the engine and the safety instructions below.
Page 17 3 Safety Regulations Safety when refueling When refueling the machine: ▪ Immediately wipe away any spilled fuel. ▪ Fill the fuel tank in a well-ventilated area. ▪ Reattach the fuel tank cap after refueling. ▪ Do not smoke. ▪ Do not refuel hot or running engines. ▪...
Page 18 ALWAYS keep fuel lines in a good condition and connected correctly. Leaking fuel and gases are highly explosive. ▪ If spare parts are required for this machine, only use parts from PRAMAC or parts that match the original exactly in terms of dimensions, model, intensity and material.
Page 19 4 Safety and Information labels Safety and information labels There are labels on your equipment that contain important information and safety instructions. ▪ Keep all labels legible. ▪ Replace missing or illegible labels. The item numbers on the labels can be found in the parts book. Item Label Description...

Page 21 6 Lifting and transporting Lifting and transporting Lifting the machine This compact generator is heavy enough to cause injury in the event of incorrect hoisting technology. Observe the following instructions to lift the generator: ▪ Do not try to lift the generator without help. Use suitable lifting bars e.g. loops, chains, twisting hooks, ramps or car jacks.
Page 22 Check the machine and its components for damage. Do not operate the machine if you find visible damage! Ask the PRAMAC dealer for advice at once. Check whether all of the parts belonging to the machine have been delivered and whether all loose parts and fasteners are present.
Page 23 7 Operation Accessories Installation (only for P7500i) Remove accessories Remove the attachment, remove the generator and attachment box from the packing box, and count the number of attachment according to the following table. Wheel kit installation Tool requirements: 12 mm wrench, 10 mm wrench, crosshead screwdriver used for battery wiring and clamp.
Page 24 The "General power requirements for starting" information only applies as a general guideline to assist you in determining the power requirements. The nearest PRAMAC dealer, tool manufacturer can help you if you have questions. NOTE: Do not exceed the specified current limit at any plug receptacle.
Page 25 7 Operation Performance loss with high altitude application Generators run differently due to altitude and temperature differences. Unmodified internal combustion engines have reduced performance at high altitudes due to the lower air pressure. This means less performance and therefore a reduced power exploitation.
Page 26 7 Operation Ground CAUTION The mid-point (neutral) conductor of this equipment is not grounded. Do not drive the PE rod into the ground under normal operating conditions. Refer to the local regulations if the equipment is intended to power a building or similar system.
Page 27 7 Operation Use of extension cables A loss of power takes place when connecting electrical equipment or a tool to the generator with an extension cable — the longer the cable, the greater the loss of power. This means that less voltage is conveyed to the electrical equipment and the input current is increased or the performance is reduced.

Page 31 7 Operation 7.10 Control Functions Throttle Throttle When the Throttle switch is in the “I” position the throttle controls the engine speed according to the connected electrical load. The results are better fuel consumption and less noise. When the switch is in the “O” position the engine runs at 4,500 rpm regardless of the electrical load.
Page 32 7 Operation After checking, restart the engine. NOTE: The Overload Alarm may come on for a few seconds when first using electrical devices that require a large starting current, such as a compressor, pump, or refrigerator. This is normal behavior it is not a malfunction. Low Oil Alarm (Red) When the engine oil falls below the required level the Low Oil Alarm will come on and the engine will stop automatically.
Page 33 7 Operation Off / Run / Choke switch The Off / Run / Choke switch controls the flow of gasoline from the fuel tank to the carburetor. The switch should be in the “I” position when starting and operating the generator. The switch should be in the “O” position when the engine is not running and when storing or transporting the unit.
Page 34 NOTE: Do not disconnect any parallel kit connections once the units are running Start both units per starting instructions. Once the green output indicator illuminates, devices can be connected and turned on using the parallel kit outlet. Follow Stopping the engine instructions NOTE: Only use Pramac approved parallel kit...
Page 35 7 Operation 7.11 Before starting DANGER Carbon monoxide. The application of a generator in buildings can LEAD TO DEATH WITHIN MINUTES. The exhaust fumes from the generator contain carbon monoxide (CO). This is an invisible odorless poison. If the exhaust fumes of the generator can be smelled, CO is being inhaled.
