1.10 Use of Extension Cords
Extension cords should be used only when absolutely
necessary. When a long extension cord is used, a
voltage loss occurs. The longer the cord the greater the
voltage loss. This results in less voltage being supplied
to the pump and increases the amount of current used. A
thicker cord with a larger wire size will reduce the voltage
loss.
For extension cords over 100' (34 m) a larger wire size
may be necessary. Consult a WACKER Service Center
for more information on wire sizes.
Use only extension cords rated for outdoor use and
equipped with a third wire ground.
CAUTION:
Operating the pump at low voltage caused
by the use of the improper extension cord can cause it to
overheat.
If the pump stops during operation, disconnect it
from the power supply immediately.
NEVER
re-
move or handle the pump while it is still connected.
WARNING
1.11 Motor Protection
This pump is equipped with built-in motor protection. If the
pump overheats, it will automatically turn itself off. The
pump will automatically reset itself and resume operation
after it has cooled.
Possible conditions which may cause the pump to turn off
include:
1. Pump operating at the wrong voltage.
2. Pump strainer blocked.
3. Pump running dry.
4. Impeller blocked.
5. Discharge hose blocked.
1.12 Periodic Maintenance
Before Use - Check cable and extension cords for wear
and damage.
Before Use - Check external hardware and tighten when
necessary.
Before Use - Check that hose connections are tight.
Every 3 Months - Change oil in pump housing.
1.13 Lubrication
To change oil in pump housing, remove pipe plug
(a)
from side of pump housing using a 6 mm hex wrench. Tip
pump on its side and allow oil to to drain. Add 4 oz. (120
ml) of Shell Tellus 30W oil through plug hole. Apply pipe
sealant to plug threads and replace plug.
a
Keep all electrical cords in good condition.
DO NOT
use worn, bare, or frayed cords. Worn cords in-
crease the risk of electrical shock.
