Preparing The Machine For Operation; Generator Operation - YATO YT-85451 Manual Original

eration of the device.
The generator must be switched off immediately if the following
symptoms are noticed:
- changes of the engine's speed of revolution,
- overheating of the devices connected to the generator,
- sparking,
- smoke or fl ames coming out of the device,
- unwanted vibration.
The fuel feed system must be checked periodically. If you notice
leaks, have the unit repaired by an authorised servicing centre.
Wait until the engine of the unit has reached its rated engine
revolutions before connecting electrical equipment.
All repairs should only be carried out by an authorised servicing
centre.
Do not allow fuel to run out while the engine is running!
Do not cover the ventilation inlets and outlets. Even when the
generator is not running.
Before transporting the generator, it is necessary to empty the
fuel tank.

PREPARING THE MACHINE FOR OPERATION

CAUTION! The checking procedure must be carried out on the
generator before each start-up.
WARNING! The generator is supplied with only a small amount
of oil in the gearbox. The oil must be topped up before the gen-
erator's fi rst operation. Check the oil level regularly and top up if
necessary. Starting the generator without oil or with too little oil in
the gearbox will cause irreparable damage to the engine.
Checking the oil level
Twist off the oil fi ller cap. The oil fi ller cap has a dipstick attached.
The oil level should be between the lower and upper limit marks
on the dipstick. If necessary, add oil to the level indicated in Fig-
ure (II).
Use four-stroke premium engine oil with the viscosity class
shown in the product specifi cations table.
Close the oil fi ller by twisting on the cap.
Caution! Put the power generator on a fl at and level surface be-
fore adding oil. If the power generator is off level, move it to a fl at
and level surface and wait at least 30 minutes for the oil level
to stabilize.
Caution! Add oil through a fi lling pistol or a funnel. This will re-
duce the risk of a spill. If spilled, thoroughly wipe off all oil before
starting the power generator.
Caution! The power generator features an oil level sensor which
will prevent ignition when the oil level is too low. If the power
generator fails to start, check the oil level.
Refuelling
93-octane unleaded petrol or better is recommended.
Use four-stroke engine fuel and oil which are free from solid im-
purities. Premium quality products are recommended. They will
extend the service life of the engine.
Do not refuel above the maximum level marked on the fuel tank.
Leave a headroom of air between the fuel level and the top of
the fuel tank.
Refuel with a fuel pump and/or a funnel. This will reduce the risk
of a spill. If spilled, thoroughly wipe off all fuel before starting the
O R I G I N A L
GB
power generator.
Never smoke when refuelling.
Open the fuel fi ller cap counter-clockwise to open. Remove the
cap from the fuel fi ller. The cap has two bosses which need to en-
gage the two locating grooves in the fuel fi ller's neck (III). Close
the fuel fi ller by twisting on the cap clockwise. This is the only
way to open and close the fuel fi ller cap.
A fuel fi lter (IV) is inside the fuel fi ller to retain some of the solid
impurities that may be present in the fuel. Always refuel the fuel
tank with the fi lter installed in the fuel fi ller. The fuel fi lter fl ange
features locating grooves. Make sure that they are engaged fully
with the bosses in the fuel fi ller.
See the product specifi cations table for the fuel tank capacity.
The insert (V) in the fuel fi lter shows the maximum fuel level. Do
not exceed the maximum fuel level shown by the FUEL LEVEL
insert.
Generator grounding
Connect the cable between the grounding system and the power
generator to the ground terminal marked on the generator. The
power generator must be connected to a grounding system by a
person with appropriate electrical qualifi cations.
With the preparations for operation complete, you may now start
the power generator.

GENERATOR OPERATION

Start-up of the combustion engine
Before starting the power generator, unplug all electrical loads
from the power outlets of the power generator.
Open the fuel supply valve by rotating it to "ON" (VI).
Move the engine ON/OFF switch to "ON" / O.
Close the throttle by moving the priming accelerator lever to stop
at "OFF" (VIII).
Caution! Do not close the throttle if the engine is warm (for ex-
ample, after a break for refuelling). In this case, move the priming
accelerator lever to "ON".
Pull the starter pull cord smoothly several times until you feel the
resistance caused by the engine compression, which is when
you should pull it vigorously and fi rmly (VIII).
While holding the handle, let the starter pull cord retract itself in
a controlled manner until it is fully inside the power generator
housing. Do not release the starter pull cord handle so that it is
suddenly retracted into the housing. This can damage the starter.
As the engine is heating up, open the throttle gradually by mov-
ing the priming accelerator lever gradually towards "ON". Allow
the engine to start running smoothly every time you reposition
the priming accelerator lever. The rate at which the priming ac-
celerator lever should be reversed depends on the ambient tem-
perature in which you start the engine. The lower the ambient
temperature, the slower the lever should be reversed.
Connecting electrical loads to the power generator
CAUTION! Do not connect electrical loads with a power rating
higher than the rated power output of the power generator. If
more than one electrical load is connected, the total rated power
of all connected loads must be lower than the rated power output
of the power generator.
CAUTION! Verify that the ratings of the electrical loads to be con-
nected match the ratings of the power generator.
