To Stop
NOTE: If the machine is unplugged, the GFCI must
be reset prior to use. Always test GFCI before each
use.
1. If detergents were used, draw clean water through
the detergent inlet line to purge detergent. Failure
to do so may clog detergent metering valve.
2. Turn burner switch off and continue spraying,
allowing the water to cool to below 100°F.
3. Turn OFF pump switch.
4. Turn OFF water supply.
5. Squeeze trigger of trigger gun to relieve system
pressure.
6. Turn off main shut-off valve on gas supply.
Storage
DANGER: Do not store flammable liquids (gasoline,
diesel fuel, solvents, etc.) near pressure washer, or
in non-ventilated areas.
Protect from freezing by storing in a heated area, or by
flushing the system with antifreeze (use an automotive
engine antifreeze or windshield washer solvent to anti-
freeze). To flush the system, fill the float tank with anti-
freeze. Start machine and allow to run until antifreeze
flows from the end of the wand. Squeeze and release
the trigger gun several times to antifreeze the unloader
system. Also draw antifreeze through the detergent
inlet line to antifreeze the detergent system. For added
protection after antifreezing, disconnect the pressure
hose from machine and remove the coil drain plug.
After coil has drained, replace pressure hose and coil
drain plug. If the pressure washer is not to be used for
an extended length of time, it is recommended that the
system be flushed with antifreeze for rust protection.

Maintenance
WARNING: Unauthorized machine modification or
use of non-approved replacement parts may cause
personal injury and/or property damage and will

Pump
Lubrication: To lubricate pump, use 10W-40 Non-
Foaming oil for pump crankcase. Crankcase must be
filled to center of sight glass window found on the rear
of the pump. During the break-in-period, make sure the
oil is changed after the first 50 hours of operation. After
that, replace oil every year or 500 hours of operation,
whichever comes first.
