Operation - Scheppach Pwp32 Originalbetriebsanleitung

• Do not use a hose* that is smaller than the suction
line* of the pump.
• The suction line* should only be as long as necessary.
• Pumping performance is best when the pump is as
close to the surface of the water as possible and the
hoses* are short.
• A leaking suction line* will prevent the water from be-
ing sucked in due to air ingress.
1. Insert the hose adapter (18) into the union nut (18a).
2. Insert the seal (18b) into the union nut (18a).
3. Screw a union nut (18a) onto the suction connection
(16) and tighten it firmly (8 - 10 Nm).
Make sure that the seal (18b) of the union nut (18a) is
in contact with the suction connection (16).
4. Attach the suction line* to the hose adapter (18) of the
suction line* with a hose clamp (19) to avoid air leak-
age and loss of suction power.
Use screwdrivers (22).
5. Fit the pre-filter (20) to the other end of the suction
line* and fasten it with a hose clamp (19).
Use a screwdriver (22).
Avoid sucking in foreign bodies (sand etc.).
If necessary, fit a pre-filter (20).
6. Disassembly takes place in reverse order.
9.4 Installation of the pressure line*
(Fig. 6)
1. Insert the hose adapter (18) into the union nut (18a).
2. Insert the seal (18b) into the union nut (18a).
3. Screw a union nut (18a) onto the pressure connection
(17) and tighten it firmly (8-10 Nm).
Make sure that the seal (18b) of the union nut (18a) is
in contact with the pressure connection (17).
4. To improve pump performance and reduce fluid fric-
tion, use a short, large diameter pressure line*. A long
or thin hose* increases fluid friction and reduces
pumping performance.
5. Attach the pressure line* to the hose adapter (18) of
the pressure line* with a hose clamp (19).
Use a screwdriver (22).
6. Disassembly takes place in reverse order.
9.5 Priming the product with water
(Fig. 7)
Notes:
Dry operation of the pump will cause damage to the pump
seals. If the pump runs dry, switch off the engine immedi-
ately and let the pump cool down before priming with wa-
ter.
If the pump is removed after use, it is essential to fill up
with water again when it is reconnected and put into oper-
ation.
Filling the suction line with water is not necessary!
1. Before starting the engine, remove the cover (8a) of
the water filling plug (8) from the pump chamber and
fill the pump chamber with water.
2. Screw in the cover (8a) of the water filling plug (8)
again and tighten it firmly.

10 Operation

10.1 Start the engine (Fig. 8)
DANGER
Danger of poisoning!
Only use the product outdoors and never in closed or
poorly ventilated rooms.
ATTENTION
– Do not let the pull starter whip back in. This can re-
sult in damage.
– In case of cool weather, it may be necessary to re-
peat the starting process numerous times.
NOTE
Only use the fuel pump "primer" when the
engine is cold!
NOTE
If the engine is being started for the first time, several
tries are required to start until the fuel has been deliv-
ered from the tank to the engine.
10.1.1
1. Turn the on/off switch (9) to the "ON" position.
2. Set the fuel valve (12) to "ON".
3. Set the "CHOKE" (13) to the "ON" position.
4. Now pull the pull starter (11) and the engine should
start.
If the engine does not start, repeat the process.
5. Once the engine is started (after approx. 15-30 sec-
onds), move the "CHOKE" (13) from the "ON" position
to the "OFF" position.
6. Use the throttle to set the required speed (14).
This is how you increase or decrease the delivery
rate.
LOW = Engine at idle speed
FAST = Maximum delivery rate
7. If the engine does not start even after several at-
tempts, read the "Troubleshooting" chapter.
Note:
Let the engine warm up at idle for about 10 minutes.
10.1.2
1. Set the fuel valve (12) to "ON".
2. Now pull the pull starter (11) quickly. The product
should start after 2 pulls. If the product has still not
started, repeat the procedure described under 10.1.1.
3. Use the throttle to set the required speed (14).
This is how you increase or decrease the delivery
rate.
LOW = Engine at idle speed
FAST = Maximum delivery rate
Note:
Let the engine warm up at idle for about 10 minutes.
