Environmental Containment Onsite Type Point 0. 0kA SDG-F series operation for the time from day & half days A big capacity fuel tank equipped as a standard one enables long continuous operation without any additional fuel tank provided. operation 0 (day) 8(day) (day) hr SDGS-F Hz Hz at % load at % load SDGS-F Hz Hz SDGS-F SDGS-F SDG00S-F SDGS-F SDGS-F Hz Hz Hz Hz Hz Hz Hz Hz Hz Hz SDG0S-F Hz Hz Point Specially designed construction for prevention of rain penetration Unlike separate fuel bund and generator oil bund, Airman s fully bunded with extended tank minimize any potential of rain water penetration into the bund and minimize the maintenance work required. Prevention of rain penetration Patent Prevention of rain infiltration Prevention of water and oil leak For the series from SDG to SDG, the portions of oil fence are formed by bending so that welding work is minimized. Further, air tight welding work is continuously performed on welded portions. Separate oil bund is not required No separate oil bund is required for the generator as well as the additional fuel tank. Additional fuel tank is not required No potential fuel leakage along the interconnecting pipes. Rain water ingress is minimized Rainwater will not be collected like traditional oil bund as it is fully integrated within the enclosure package. Complete package is fully transportable Without separate fuel tank and oil bund, the fully integrated generator with long-range tank and integrated bund is fully transportable as one package. Convention package Engine generator Portion of oil bund tank Additional fuel tank Air inlet port is specially designed to increase intake air and to reduce the suction pressure inside to minimize the potential rain water penetration. Facilitated maintenance Utility model Oil fence can be easily removed and reinstalled by removing the stud bolts ( 8 pieces ). Insert type seal which is usually used for automobile is adopted so that rain penetration can be avoided. Double wall steel fuel tanks have 0% fluid capacity containment. Warning indicator The warning lamp on the panel goes on when oil / water is filled in the oil bund. tank is provided with Oil bund line bund lifting hooks as ( for generator ) ( for additional fuel tank ) standard. Oil bund and Oil Fence are same meaning

3 High Generating Performance Better Generating Performance SDG series generators are coupled to low transient reactance alternator and reinforced damper coil. This increases the negative-phase-sequence current capability and minimizes the output waveform distortion. Therefore, they are suitable for wide range of non-linear load such as inverter, thyrister, computer control, discharge lighting, precision instruments and instrumental device. 0 Preset oltage Regulation within 0.% Fully Equipped Dual oltage s By changing over the short connecting plate in the control panel, the three phase output voltage can be switched to 00/0 from 00()/0 and vice versa. When starting engine, the indication lamp at the operation panel goes on to display the operating voltage iediately. 00/0 00()/0 phase 00/0 phase / U W O switch phase 00()/0 phase ()/ U W O Environmental Friendly Low Noise Level Operating noise has been minimized with low noise engines, equipped with highly attenuated muffler and special exhaust system design. All SDG models (excluding SDG00S) are adopted panel structure to minimize structural clearance and reduce internal space. Combined inlet duct design further reduces the overall noise level. Exhaust muffler system is mounted on special design support structure to reduce vibration. Super Silent SDGS~0S Ultra Super Silent SDGAS~AS Silent SDG00S~0S Clean Engine SDG~(excluding AS,S-F,S) 00S-F~S-F generators are approved by Japanese Government Authority as "The rd Driven Construction Machinery Exhaust Gas Regulation". Other generators are approved by Japanese Government Authority as "The nd Driven Construction Machinery Exhaust Gas Regulation".

They are driven by such environmental friendly engine to keep the generator outside as well as the inside from being stained. Operation available for a long time A large capacity fuel tank and low fuel consumption engine have made the generators run continuously for a long time. Also for SDGS~00S three-way selection valve is provided as a standard equipment to be easily connected to an additional outside fuel tank. One way selection method by one selection lever avoids wrong operation when changing over suction side to return side and vice versa. In case the mounted fuel tank is used Selector handle Plug Engine being fueled by separate fuel tank Suction side Return side Automatic Air Bleeding System (SDG~) Automatic Air Bleeding Device is equipped to automatically bleed air from fuel line system. This eliminates the need to prime the fuel system again should the generator be shutdown due to running out of fuel. Simply top up the fuel and turn the key switch to operation position, air in the fuel line system is bled automatically. As for both SDGS/S/AS, it is possible to automatically bleed air by pushing the push button provided at the operation panel. Parallel Operation (SDG,S/AS) High Accurate Parallel Operation System (CCR cross current prevention device) is provided as a standard equipment. Combined with an accurate AR(automatic voltage regulator), it is possible to perform parallel operation manually. 0 Selector handle Separate fuel tank

4 Easy Maintenance Operation filter air-bleeding electromagnetic pump Air cleaner pump Reserve tank Engine Starting Efficiency For SDG~0, engine preheating system consists of quick heating glow plug to easily start up engine in low temperature conditions. SDG0~0 are driven by high start-up engine which exercises great power for earth auger and vibro-haer operations requiring instant electric flow. Start-up characteristics have been more improved for electric motor start-up as well as turbo charger and governor improved. Electronic Governor (SDG~,00S-F~S-F,0,00,0) Stable engine speed can be secured because engine speed is made easier to be adjusted. It is possible to select frequency and make fine adjustment of engine speed only by moving up and down "Switch for fine adjustment of engine speed". It is also possible easily to perform" Idling Operation" with the slowdown switch. Control Panel Engine oil level gauge Engine oil filter Maintenance with Great Ease Daily inspection such as engine oil and coolant level can be done by opening the right side door. For SDG &, one battery of two mounted batteries has been eliminated, thus dedicated to reducing industrial waste and maintenance cost. Engine oil filler port Sedimentor SDGS-F Radiator Flat Frame (SDG~00, excluding AS/00S/AS) The interior of the machine is flatly constructed so as to be easily cleaned. Control devices for generator and electrical appliances for engine are concentrated inside the control panel for better maintenance.

It is easy to clean the interior by removing the fuel tank. Radiator Safety Inspection and Cleaning Radiator For SDG series inspection of radiator and cleaning radiator can be easily performed by removing both side front covers and dividable fan shrouds. Maintenance Cycle Newly-Designed Panel Construction (excluding00s) The bonnet is of panel constructed type for easily dismantling and assembling for maintenance. unit : per hour Completely Monitoring System For SDG~, 00S, in order to eliminate the electric fault when restarting engine, they are provided with shunt trip as standard equipment to trip the main circuit breaker in case of emergency shutdown.

When using generators for extremely low efficientwelders, reduce the numbers of welders. When using generators for AC arc welders equipped with condenser, it is necessary to be very careful for self-exciting phenomena (Output voltage of generator extremely increases in case of no load or light load). The above table shows the numbers of welders when operating 0%. In case of more Percentage than 0%, reduce the numbers of welders. When using generators for more welders than units, connect evenly it to each welder, not concentrating one unit only.
