9. Use
9.1 Initial use (first time only)
Check the equipment for damage. Do not use the equipment if it is not in good condition. Notify
the supplier. Check whether the warranty registration card has been supplied and filled in. This
must be sent back to Holmatro to register your warranty.
When you receive the pump it must first be made ready for operation. Perform the following
actions:
* Remove the red shipping cap from the hydraulic tank and replace it with the orange breather
cap. Note: Keep the red shipping cap and label for future shipping.
* Check the pump for external damage.
* Open the hydraulic fill cap vent.
Note: Keep the hydraulic fill cap label for future shipping.
* Check whether the bottle with engine oil has been supplied.
* Fill the crankcase with the specified amount of engine oil. The engine will be shipped with
approx. 20cc of additive for the first time use of the engine. Do not remove the additive.
* Fill the fuel tank with un-leaded gasoline up to the required level.
* Open the fuel cap vent.
* Switch the choke lever to its CHOKE position.
* Turn the engine switch to the ON or "1"position. This also opens the fuel valve.
* Pull the recoil starter until resistance is felt, let the cord be retracted and then pull fast.
Repeat this if the engine does not start the first time. This unit may require several pulls to
start the engine when it is received new from the factory. After the initial start-up the engine
should start after a few pulls of the recoil.
* Guide the starting cord back after starting.
Switch the choke lever to RUN after approx. 20 – 30 seconds, or when the engine begins to run
irregularly.
NOTE: Run the engine for at least 20 minutes or until the engine reaches operating temperature.
(Depending on ambient temperature. Run the engine longer in colder weather)
After verifying that the equipment operates, turn off the engine. To properly prepare the engine to
start again, the following shut down procedure is recommended:

Turn the engine switch to the OFF or "0" position.

Switch the choke lever to the CHOKE position and try to start the engine. The engine may
re-start and run for a few seconds. This is okay. If the engine does not start, pull the recoil
four more times.

On the last pull, pull the recoil slowly until resistance is felt. This will close the valves so
that moisture cannot enter the engine cylinder.

Leave the engine switch in the OFF or "0" position until ready to re-start the engine.
The pump is now ready for use.
