STORAGE & MAINTENANCE
MAINTENANCE-DAILY:
INSPECT ELECTRICAL CORD: Detach unit from power source and
inspect electrical cords to ensure they are free of cuts. If a cut is
found, replace cord before operating unit.
TEST GFCI: If applicable, test the GFCI. Testing varies according to
the specific GFCI. Follow the instructions given on the GFCI for
correct procedures.
CHECK WATER PUMP OIL LEVEL: Make certain the oil is on the "FULL"
mark on the dipstick or in the center of the oil sight glass. If the oil
appears to be low, fill with SAE20 or 30 non-detergent pump oil.
OIL LEAK INSPECTION: If a leak is found, promptly eliminate any
leaks found in the pumping system. Be sure that all damaged parts
are replaced and that the mechanical problems are corrected prior
to operation of the unit. If you require service, contact Customer
Service.
FUEL LEAK INSPECTION: If a fuel leak is found, turn unit off immediately!
See "Risk of Explosion or Fire", pg. 5. Be sure that all damaged parts
are replaced and that the mechanical problems are corrected prior
to operation of the unit. If you require service, contact Customer
Service.
WATER LEAK INSPECTION: If a leak is found, promptly eliminate any
leaks found in the pumping system by removing suspect parts, applying
thread sealant to the threads and reinstalling. If using teflon tape, be
certain no tape gets inside any plumbing to prevent the possibility of
a plugged spray nozzle. Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of
the unit. If you require service, contact Customer Service.
HOSE INSPECTION: Inspect high pressure hoses for kinking, cuts
and leaks. If a cut or leak is found, DO NOT USE HOSE! Replace
hose before starting unit. See "Risk of Injection or Severe Cutting
Injury", pg. 6. Be sure that all damaged parts are replaced and that
the mechanical problems are corrected prior to operation of the unit.
If you require service, contact Customer Service.
WATER STRAINER INSPECTION: Ensure the water strainers (A) are
clean and free of any obstructions. Periodic cleaning of the water
strainer will help prevent pump problems. As a strainer becomes
obstructed, it restricts proper flow of water to the pump. This can result
in cavitation which will cause premature failure of pump packings.
Remove strainer screens (A), clean or replace.
QUICK COUPLERS INSPECTION: There are o-ring seals inside the
couplers which will deteriorate. To replace, simply install a replacement
o-ring to correct the leak. (Additional o-rings can be purchased from
your dealer.)
HIGH PRESSURE NOZZLE: Inspect high pressure nozzle for wear or
obstructions. Clean or replace if necessary.
FUEL FILTER/WATER SEPARATOR: Inspect bowl on fuel filter/water
separator for water accumulation. If water exists, unscrew drain
valve on bowl to drain water, then close.
