Operation techniques:
The machine may suddenly stop and
require a rest period from time to
time; this is normal and does not
indicate a problem (See Trouble-
shooting, page 20). However, cer-
tain operating techniques may help
reduce or even prevent the need for
such rest periods, increasing effi-
ciency:
Do not release the trigger between a.
sweeps. Release the trigger as few
times as possible during use. In-
terrupted or sporadic spraying will
cause the unit to heat up quickly and
will increase the need for rest peri-
ods.
Make sure that all obstacles have
b.
been moved and the entire area is
ready before starting.
For small jobs, try to finish an entire
c.
portion of the job before taking a
break.

After cleaning this area, switch off the
pressure washer and inspect the area
carefully for any damage or discolor-
ation. If any damage is noted from
the pressure setting, use a lighter
setting when cleaning the rest of the
area. If damage or discoloration is
