5.1

General information

5.1.1 Set up the pump as close as possible to the suction point on a stable surface.
The pump has to be positioned within a flood-protected area.
The engine has to be protected from moistness.
Before application, the pump casing has to be filled with
water through the cup on top of the casing.
5.1.2 Connect suction hose, suction basket and pressure hose. Do not kinck the
hose, use an anti-kinck protection (MAST item-nr.: 501, optional), if needed. Use
only airtight hoses, otherwise the suction process could fail.
Never run the pump without suction basket!
5.1.3 Start the engine as described in the attached operation manual of the
engine manufacturer. If not available, refer to the following chapters.
The suction process starts automatically. The delivery starts
after 20 to 300 sec., depending on suction depth and length of
the suction hose.
5.1.4 The pump is dry-running safe. Though, a longer period of dry-running should
be avoided, because of consequential higher wear-out and for power saving
reasons.
5.1.5 When delivering calcareous water, the pump has to be decalsified frequently.
5.2

Startup with petrol engine

The pumps with 4-stroke petrol engine must be positioned at
inclination below 15°. Above, lubrication may fail.
Check the oil-level before starting!
Engine start:
At cold engine, shift the lever to „CHOKE". At warm engine, shift it to „RUN",
and put the speed lever to full power („rabbit"). The power switch has to be pushed to
ON / EIN (I). Actuate the engine with the hand starting rope. Do not the pull the rope
to the end, and return it smoothly. After the engine has started, put the shifter from
„CHOKE" to „RUN".
