4 GENERAL POWER TOOL SAFETY WARNINGS

Read all safety warnings and instructions. Failure to heed warnings and follow instructions may result in electric shock, fire and/or serious injury. Keep safety warnings and instructions for future reference. The term "power tool" in the safety warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

4.1 Working area

§ Keep working area clean and well lit. Untidy and dark areas can lead to accidents.

§ Do not operate power tools in potentially explosive surroundings, for example, in the

presence of inflammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

§ Keep children and bystanders at a distance when operating a power tool. Distractions can cause you to lose control of it.

4.2 Electrical safety

Always check that the power supply corresponds to the voltage on the rating plate.

§ Power tool plugs must match the outlet. Never modify the plug in any way. Do not use adapter plugs with earthed power tools. Unmodified plugs and matching outlets will reduce the risk of a lethal electric shock.

§ Avoid body contact with earthed surfaces such as pipes, radiators, kitchen ranges and refrigerators. There is an increased risk of a lethal electric shock if your body is earthed.

§ Do not expose power tools to rain or wet conditions. If water gets inside a power tool, it will increase the risk of a lethal electric shock.

§ Do not damage the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of a lethal electric shock.

§ When operating a power tool outdoors, use an extension cable suitable for outdoor use. Using a cord suitable for outdoor use reduces the risk of a lethal electric shock.

§ If operating a power tool in a damp location is unavoidable, use a power supply protected by a residual current device (RCD). Using an RCD reduces the risk of a lethal electric shock.

4.3 Personal safety

§ Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool when you are tired or under the influence of drugs, alcohol or medication. A moment of inattention when operating a power tool may result in serious personal injury.

§ Use safety equipment. Always wear eye protection. Using safety equipment such as a dust mask, non-skid safety shoes, a hard hat, or hearing protection whenever it is needed will reduce the risk of personal injury.

POW4820-POW4830(SC) EN

§ Avoid accidental starts. Ensure the switch is in the off position before inserting the plug. Carrying power tools with your finger on the switch or plugging in power tools when the switch is in the on position makes accidents more likely.

§ Remove any adjusting keys or spanners before turning on the power tool. A spanner or key left attached to a rotating part of the power tool may result in personal injury.

§ Do not reach out too far. Keep your feet firmly on the ground at all times. This will enable you retain control over the power tool in unexpected situations.

§ Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from the power tool. Loose clothes, jewellery or long hair can become entangled in the moving parts.

§ If there are devices for connecting dust extraction and collection facilities, please ensure that they are attached and used correctly. Using such devices can reduce dust-related hazards.

4.4 Power tool use and care

§ Do not expect the power tool to do more than it can. Use the correct power tool for what you want to do. A power tool will achieve better results and be safer if used in the context for which it was designed.

§ Do not use the power tool if the switch cannot turn it on and off. A power tool with a broken switch is dangerous and must be repaired.

§ Disconnect the plug from the power source before making adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

§ Store power tools, when not in use, out of the reach of children and do not allow people who are not familiar with the power tool or these instructions to operate it. Power tools are potentially dangerous in the hands of untrained users.

§ Maintenance. Check for misalignment or jammed moving parts, breakages or any other feature that might affect the operation of the power tool. If it is damaged, the power tool must be repaired. Many accidents are caused by using poorly maintained power tools.

§ Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to jam and are easier to control.

§ Use the power tool, accessories and cutting tools, etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work which needs to be done. Using a power tool in ways for which it was not intended can lead to potentially hazardous situations.

4.5 Service

§ Your power tool should be serviced by a qualified specialist using only standard spare parts. This will ensure that it meets the required safety standards.

5 SAFETY INSTRUCTIONS

§ The generator is designed to give safe and dependable service if operated according to instructions.

§ Read and understand the Owner's Manual before operating the generator. Failure to do so could result in personal injury or equipment damage.

§ Exhaust gas contains poisonous carbon monoxide. Never run the generator in an enclosed area. Be sure to provide adequate ventilation.

§ The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before storing the generator indoors.

§ The engine exhaust system will be heated during operation and remain hot immediately after stopping the engine. To prevent scalding, pay attention to the warning marks.

§ Gasoline is extremely flammable and explosive under certain conditions. Refuel in a well ventilated area with the engine stopped.

POW4820-POW4830(SC) EN

§ Keep away from cigarette, smoke and sparks when re-fuelling the generator, Always refuel in a well ventilated location.

§ Wipe up spilled gasoline at once.

§ Connections for standby power to a building's electrical system must be made by a

qualified electrician and must comply with all applicable laws and electrical codes. Improper connections can allow electrical current from the generator to back feed into the utility lines. Such back feed may electrocute utility company workers or others who contact the lines during a power outage, and when utility power is restored, the generator may explode, burn, or cause fires in the building's electrical system.

§ Always make a pre-operation inspection before you start the engine. You may prevent an accident or equipment damage.

§ Place the generator at least 1m (3ft) away from buildings or other equipment during operation.

§ Operate the generator on a level surface. If the generator is tiled, fuel spillage may result.

§ Know how to stop the generator quickly and understand operation of all the controls.

Never permit anyone to operate the generator without proper instructions.

§ Keep children and pets away from the generator when it is in operation.

§ Keep away from rotating parts while the generator is running.

§ The generator is a potential source of electrical shocks when misused; do not operate with

wet hands.

§ Do not operate the generator in rain or snow and do not let it get wet.

10.3 Hot

§ Shove the choke completely to the right to restart a hot motor.

§ Shove the choke to about halfway to restart a warm motor.

A hot motor will not start if there is too much fuel in the cylinder. If this happens, wait five to ten minutes before trying again. Shove the choke completely to the right and the motor should start.

§ Set the motor switch in the “ON”-position.

Fig 11 11.1 Engine switch

§ Pull slightly on the start cord until you feel resistance and then yank hard and swiftly.

Fig 12 12.1 Starting grip

Do not let the start cord retract by itself: guide it back by hand.

Hold the carrying handle firmly to prevent the generator from falling over when you pull the start cord.

§ After the engine starts, allow the engine to run continuously and warm up.

POW4820-POW4830(SC) EN

§ Press the choke in completely after the engine is started.

If the engine stops and will not restart, check the engine oil level before troubleshooting in other areas.

Fig 9 9.2 Move to the right to deactivate

Before using the device once it is connected, switch off the ECO switch.

8.2 High altitude operation

At high altitude, the standard carburettor air-fuel mixture will be excessively rich. Performance will decrease, and fuel consumption will increase. High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburettor and readjusting the slow tempo screws. If you always operate the generator at altitudes higher than 1,500 m (5,000 feet) above sea level, have your dealer perform these carburettor modifications. Even with suitable carburettor jetting, engine horsepower will decrease approximately 3.5% for each 300m (1,000 feet) increase in altitude. The effect of altitude on the horsepower will be greater than this if no carburettor modification is made.

Operation of the generator at an altitude lower than the carburator is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture.

8.3 Generator use

8.3.1 Warning!

§ To prevent electrical shock from faulty appliances, the generator should be grounded.

Connect an electric conductor (cable) of at least 1.5mm² between the generator's ground terminal and an external ground source.

10 TRANSPORTING AND STORAGE

To prevent fuel spillage when transporting or during temporary storage, the generator should be secured upright in its normal operating position, with the engine switch OFF. The fuel cap vent lever is turned counter clockwise to the OFF position. Allow the engine to cool well before turning the fuel cap vent lever to the OFF position.

10.1 When transporting generator:

§ Do not overfill the tank. (there should be no fuel in the filler neck)

§ Do not operate the generator while it is on a vehicle. Take the generator off the vehicle

and use it in a well ventilated place.

POW4820-POW4830(SC) EN

§ Avoid a place exposed to direct sunlight when putting the generator on a vehicle. If the

generator is left in an enclosed vehicle for many hours, high temperature inside the vehicle could cause fuel to vaporize resulting in a possible explosion.

§ Do not drive on a rough road for an extended period with the generator on board. If you

must transport the generator on board. If you must transport the generator on a rough road, drain the fuel from the generator beforehand.

10.2 Before storing the unit for an extended period:

§ Be sure the storage area is free of excessive humidity and dust.

§ Drain the fuel.

Gasoline is extremely flammable and explosive under certain conditions.

Do not smoke or allow flames or sparks in the area.

§ Completely drain the fuel from the tank. Open the fuel valve, start the engine and operate

it in the idle position until all remaining fuel is gone and the engine stops automatically.

§ Discharge oil.

§ Remove spark plug and fill cylinder with 2cc’s fresh oil. Pull start motor 3-4 times to

discharge the remaining oil. Then reinstall the spark plug.

§ Pull the starting cord slowly until resistance is strong. At this time, the piston is moving to

the top of the compression stroke and the valves will be closed.
