Troubleshooting Information
KMR 1250 B, LPG, D
Check seal on filter housing
Up until S/N 10033, the seal was applied to the
impeller fan inlet. Later, in an effort to improve
seal effectiveness, it was attached to the filter
housing.
With the filter housing lowered, the seal must
reliably seal off the transition to the housing.
Seal on filter housing
Seals on brush well (rear view with raised container)
Checking tire pressure
Check seals on brush well
The three seals shown at left serve to seal off the
brush roller well from the debris container.
The seals must be replaced as required.
Check impeller fan drive belt
The drive belt (see page 14 pos. 3) is elastic and
cannot be adjusted.
Replace belt as required.
Excessive Unit Dusting
KARCHER
Check tire pressure
A too low tire pressure causes a sinking of the
sealing lips and sealing strips and thus a worse
sweeping result.
(See “Specifications” for tire pressures.)
