1. GENERAL SAFETY INFORMATION:
Danger Warning Caution
1.1. A “LAYMAN” and or “CHILDREN” may not recognize the possible dangers of operating a
Welder Generator. We recommend that only competent persons should operate the Welder
Generator.
1.2. Fuel is combustible and easily ignited. Do not refuel during operation.
1.3. Do not refuel whilst smoking or near naked flames. Do not over fill or spill fuel. If this happens
clean the fuel on and around the Welder Generator properly before operating.
1.4. Only use the specified fuel and oil when operating the Welder Generator.
1.5. Some parts of the internal-combustion engine are hot and might cause burns. Pay attention
to the warning signs on the generating set.
1.6. Engine exhaust gases are toxic. Do not operate the Welder Generator set in an unventilated
room. When installed in a ventilated room, additional requirements for fire and explosion
protection shall be observed.
1.7. Regularly check that the bolts and nuts are properly tightened as they may become lose due
to the vibration of the Welder Generator whilst in operation.
1.8. Before using the Welder Generator ensure that you have checked the periodic maintenance
4
schedule in the operator manual.
1.9. Always use a face shield/welding mask when welding with the Welder Generator. Your face
and eye protection is of the utmost importance.
1.10. Looking at a welding arc may cause damage and or severe pain to your eyes and even
possible temporary blindness. DO NOT BE NEGLIGENT.
1.11. Always wear the correct specified gloves when operating the Welder Generator.
1.12. Always wear the correct specified safety shoes/boots when operating the Welder Generator
1.13. Always wear an apron when operating the Welder Generator.
2. ELECTRICAL SAFETY INFORMATION:
2.1. Electrical equipment including cables, cords and plug connections must not be defective.
Please check before using.
2.2. Do not plug a Welder Generator directly into a wall socket – outlet.
2.3. The Welder Generator shall not be connected to other power sources such as the power
company supply mains. In special cases where stand-by connection to existing electrical
systems or integration therewith is intended, note that it is a legal requirement that such
connection or integration may only be performed by a competent person.
2.4. Protection against electrical shock depends on circuit-breakers that are specially matched to
5
the Welder Generator. If a circuit breaker requires replacement, it shall be replaced by a
circuit breaker that has identical ratings and performance characteristics.
2.5. Due to high mechanical stresses only tough rubber-sheathed flexible cable should be used
2.6. If the Welder Generator is of Class II construction then earthing of the Welder Generator is
not required.
2.7. Cord Extensions Sets:
When a cord extension set is connected to the generating set the following should be
considered:
2.7.1. A 1mm2 flexible cable can draw a maximum of 10A provided that the cable is not longer
than 25m.
2.7.2. A 1.5mm2 flexible cable can draw a maximum of 10a provided that the cable is not longer
than 35m
2.7.3. A 1.5mm2 flexible cable can draw a maximum of 16a provided that the cable is not longer
than 20m
2.7.4. A2.5mm2 flexible cable can draw a maximum of 10a provided the cable is not longer than
65m
2.7.5. A 2.5mm2 flexible cable can draw a maximum of 16a provided that the cable is not longer
than 45m
6
2.7.6. A 4mm2 flexible cable can draw a maximum of 10a provided that the cable is not longer
than 100m
2.7.7. A 4mm2 flexible cable can draw a maximum of 16a provided that the cable is not longer
than 65m
3. VOLTAGE DROP IN ELECTRIC EXTENSION CORDS
When a long electric extension cord is used to connect an appliance or tool to the generator, a
certain amount of voltage drop or loss occurs in the extension cord which reduces the effective
voltage available for the appliance or tool.
The chart below has been prepared to illustrate the approximate voltage loss when an extension
cord of 300 feet (approx.100 meters) is used to connect an appliance or tool to the generator.

5. PRE OPERATING INSPECTION:
Caution
5.1. Engine Oil – This is a major factor affecting the performance and life span of the Welder
Generator. Do not use non-detergent and 2 stroke oil as this will damage the Welder
Generator.
5.2. Before using the Welder Generator check the oil level, ensure that the unit is on a flat and
level surface when doing this and that the unit is “OFF”
5.3. The recommended oil to use is 4 – stroke gasoline engine oil IE SAE10w-30
5.4. Running the Welder Generator with insufficient engine oil will cause damage to the Welder
Generator.
5.5. Please note that the Welder Generator is fitted with a “low oil alert sensor”.
5.6. Only use clean un- leaded fuel when operating/running the Welder Generator.
Dirty/contaminated fuel will cause damage to the Welder Generator and will affect the
performance.
Warning
5.7. Gasoline is extremely flammable, exercise extreme caution when putting fuel into the fuel
tank. DO NOT BE NEGLIGENT.
