PHW SERIES PRESSURE WASHER
OPERATOR’S MANUAL
LANDA PHW • 9/02
GENERAL WASHING
TECHNIQUES
This machine is equipped with a spray gun and various
nozzle patterns, use the wide patterns on easy soil re-
moval jobs and the narrow patterns on the more difficult
jobs or tight areas such as cracks and holes.
In most cases, faster results and better detergent
economy will be obtained by applying the detergent and
letting it “set” for a few minutes, prior to rinsing. This en-
ables it to do its soil penetrating and loosening work.
Most cleaning work terminates with a high pressure rinse
as part of the normal cleaning procedure. In some cases,
however, the last operation may be the application of a
detergent (sanitizing, for example). After such work, run
machine for 20 - 30 seconds to clear the pump and lines.
Do not run anything through this machine that will dam-
age the steel heating coil and pump.
STEAM COMBINATION
❑
Open the pump access panel.
❑
Turn the unloader knob counterclockwise lightly un-
til you feel resistance. (Detergent will not siphon when
the steam valve is opened.)
❑
Turn the thermostat knob to the 270° mark. (The ther-
mostat is a high limit device and does not regulate
temperature).
❑
To stop, reverse steps 1 to 3 and set all controls to
their original settings.
❑
Turn burner switch off, open trigger on spray gun
and allow water to cool.
PREVENTATIVE
MAINTENANCE
❑
Use clean fuel - kerosene, No. 1 home heating fuel
or diesel. Clean or replace fuel filter every 100 hours
of operation. Avoid water contaminated fuel as it will
seize up the fuel pump. De-soot coils monthly or use
an additive if diesel is being used.
❑
Check to see that water pump is properly lubricated.
❑
Follow winterizing procedure to prevent freeze dam-
age to pump and coils.
❑
Always flush detergents from system after use.
❑
If water is known to be high in mineral content, use a
water softener on your water system or use a
LANDA
recognized coil cleaning detergent.
❑
Do not allow acidic, caustic or abrasive fluids to be
pumped through the system.
❑
Always use high grade quality
LANDA cleaning de-
tergents.
❑
Never run pump dry for extended periods of time.
❑
Periodically delime coils as per instructions.
❑
If machine is operated with smoky or eye-burning
exhaust, coils will soot up and prevent water from
reaching maximum operating temperature. See sec-
tion on burner adjustments.
MAINTENANCE AND SERVICE
Pump Lubrication:
Use only
LANDA SAE 30 weight, non-detergent oil.
Change oil after first 50 hours of use. Thereafter, change
oil every three months or at 500 hour intervals. Oil level
should be checked through use of dipstick found on top
of pump or red dot visible through oil gauge window. Oil
should be maintained at that level.
Fuel:
Use clean (not contaminated with water and debris) kero-
sene, No. 1 home heating fuel or diesel. Drain fuel tank
and replace fuel filter every 100 hours of operation.
