Low-oil safety feature
The low-oil safety feature serves to avoid damage to the engine in case there is insufficient engine oil in the crankcase.
Before the engine oil level falls below the safety limit, the low-oil safety feature automatically switches the engine off (the
motor switch remains in the ON position when this happens).
6.4. Filling the pump with water, venting the system
Prior to putting the pump into operation for the very first time, the pump
housing should be fully vented - i.e. filled with water - even in the case of self-
priming units. If this venting is omitted, the pump will not suck in the liquid to be
discharged. It is highly recommendable, yet not mandatory, to vent the intake
line as well, i.e. to fill it with water.
Please use the filling opening to fill the pump housing with water. Check to make sure that no leakage is present.
Then close the filling opening airtight. It is recommendable - but not indispensable - to fill the intake line with
water, too.
Petrol engine pumps are self-priming. This means that putting them to operation requires only the pump casing to
be filled with water, i.e. not necessarily the intake line, too. However, in this case the pump will take some more
minutes to suck in the liquid to be discharged. The additional filling of the intake line will facilitate and accelerate
the first suction cycle considerably. If the intake line is not filled with liquid, it might be necessary during putting to
operation to fill the pump housing more than once. This will depend on the length and diameter of the intake line.
To permit the air to escape, you should open a shut-off devices in the pressure line, such as for instance a faucet.
6.5. Starting the engine
To start the engine of an LTP 250/25 model, you have to put the ignition breaker to the "ON" position, the choke
lever to the start position, and the throttle control to "full throttle". Subsequently, pull the starter rope several times
strongly until the engine starts. As soon as the engine is running, slowly move the choke lever to the "operating"
position. Priming will start as soon as the engine has begun to run. During this process, please leave the throttle
control in the "full throttle" position. As soon as the liquid is being discharged evenly without any noticeable air
admixture, priming is completed and the system is fully vented. The throttle control can now be set according to
the specific needs.
6.6. Operation
The petrol engine pump must not run with the withdrawal point being shut off.
The pump must not be operated permanently in the absence of water. This so-called dry
running - i.e. the operation of the pump without any water being discharged - may cause
considerable damage to the unit.
The petrol engine pump including the entire line system have to be protected from frost and
climatic influences.
Combustible or easily inflammable or explosive matters and objects are to be kept out of the
area of the pump while in operation.
Please do not top up fuel motor oil while the engine is running. Stop the pump for fuelling it.
During operation, some parts of the petrol engine pump become extremely hot, for instance
the exhaust pipe and its cover. After switching the device off until its cooling down, to avoid
injury by burning, the device must only be touched at the points provided for this purpose, e.g.
at the control elements or handles.
During the first 20 hours of operation of a new device, the engine must not be operated at its full capacity. During
this period of time, operation at two thirds of the possible speed is recommended. During this running-in period,
full-throttle operation is admissible only for short periods of time up to a max. of 10 minutes, for instance during
the priming operation at the time of putting the units to operation.
The pump must not be operated permanently in the absence of water. This so-called dry running - i.e. the
operation of the pump without any water being discharged - may cause considerable damage to the unit because
the required cooling is missing. If necessary, you have to stop the engine, check the intake line and the
connection ports for leakages and refill the pump body and possibly the intake hose, too, with water.
