Service Schedule - Kärcher AP 100/50 M Operating Instructions Manual

PERIODIC MAINTENACE
Twice a month, flush a white vinegar solution (one
quart vinegar to two gallons of water) or anti-
browning solution (mixed as directed) through the
machine. This will prevent build-up of alkaline
residue in the system. If spray jets become clogged,
remove the spray tips, wash them thoroughly, and
blow dry.
NOTE: Do not use pins, wires, etc. to clean nozzles
as this could destroy the spray pattern.
Periodically inspect all hoses, electrical cables and
connections on your machine. Frayed or cracked
hoses should be repaired or replaced to eliminate
vacuum or solution pressure loss. The electrical
cable must be well insulated and cable connector
screw kept tight. If the cable insulation is broken or
frayed, repair or replace immediately. Don't take
chances with elctrical fire or shock.
