❶ BRUSH
❷ SLIP RING
❸ BRUSH HOLDER
❹ FLANGE BOLTS
❺ BRACKET COVER
❻ FLANGE BOLTS
Disassembly
1. Remove the two fl ange bolts (M5 x 20), then
remove the bracket cover.
2. Remove the two fl ange bolts (M5 x 16), then
remove the brush.
Assembly
1. While pressing the brush against the slip ring,
secure it (1.5~2N•m) by tightening it with the two
fl ange bolts (M5 × 16).
When doing so, confi rm that the brush is in the
proper position relative to the slip ring.
2. Secure the bracket cover (3~4N•m) by tightening it
with the two fl ange bolts (M5 × 20).
When furnishing the generator as emergency electric
power source, periodic operation and inspection are
needed.
Fuel (gasoline) and engine oil will be deteriorated with
time, and this causes that the engine is diffi cult to start
and as the results improper engine operation and fault.
CAUTION
Since the fuel (gasoline) will be deteriorated
with time, replace fuel (gasoline) with fresh one
periodically; once every three (3) months is
recommended.
When transporting the generator, make sure that the
fuel (gasoline) should be drained from the tank.
WARNING
■
To prevent fuel spillage due to the vibration
and impact, never transport the generator
with the fuel (gasoline) fi lled in the tank.
■
Secure the tank cap thoroughly.
■
To avoid the risk of the gasoline fl ammability,
never leave the generator in an area exposed
to direct sunlight or high temperatures for a
long time.
■
Keep the fuel (gasoline) in the exclusive
gasoline storage tank made by steel when
transporting.
(a) Turn the engine switch to the “STOP” position.
(b) Drain the fuel from the tank.
(c) Secure the tank cap.
CAUTION
■
Do not place any heavy objects on the
generator.
■
Select and place the generator in the proper
position of the transport vehicle so that the
generator not be moved or fallen down.
Fix the generator with rope as necessary.
This is done because if the length of the brush gets
any shorter, its contact pressure with the slip ring will
decrease, resulting in a drop in generator effi ciency
and the output voltage.
Check the brush every 500 hours to confi rm its length.
In addition, check the brush length if the generator
malfunctions, such as when it is not generating power
or its voltage is low.
(a) Check the fuel (gasoline), engine oil and air
cleaner.
(b) Start engine.
(c) With appliance such as lightings activated, run the
engine for over ten minutes.
(d) Check for the following items;
■
Proper engine running.
■
Adequate output and the indicator lamp turned on
properly.
■
The engine switch normally operated.
■
No leakage of engine oil and fuel (gasoline).
