(continued)
UNLOADER
To adjust the pressure
turn the unloader handle.
Rotate handle in a
counter-clockwise
direction to reduce
pressure. Rotate in a
clockwise direction to in-
crease the pressure back to the maximum.
(Maximum pressure is set at the factory. Tamper-
ing with the setting will void pump warranty).
DIRT KILLER NOZZLE
When cleaning hard
surfaces such as concrete,
steel, etc, you may achieve
better and faster cleaning
results by using the Dirt
Killer or Industrial Dirt Killer
rotary nozzle.
The Dirt Killer and Industrial Dirt Killer nozzles hit
much harder than regular spray nozzles and
should be used carefully to avoid damage to
surfaces to be cleaned. To insure long life of your
Dirt Killer nozzle follow these simple rules: 1) al-
ways point the nozzle down when starting to spray,
2) do not use with water hotter than 160
degrees F., 3) keep dirt out of the nozzle.
WARNING
- Do not use a rotary nozzle on
wooden or painted surfaces. It may damage the
wood or remove the paint.
VARIOJET NOZZLE
Models H200, H357, H260,
come equipped with the
Variojet nozzle. For high
pressure spray pull back on
the nozzle body. For low
pressure application of
soap/chemical, push the
nozzle body forward. To
vary the fan spray angle
twist the nozzle body to desired angle.
SPECIAL INSTRUCTIONS FOR HOT
WATER PRESSURE WASHERS
PRESSURE SWITCH
Dirt Killer hot water pressure washers use a
pressure switch to control burner ignition. When
the gunjet trigger is pulled the pressure switch
detects the pressure in system and ignites the
burner. When the gunjet is closed, and the pump
is in by-pass mode and no pressure is registered
on gauge; the pressure switch shuts down the
burner. At no time should the burner be on when
the gunjet is closed. If this occurs, shut off the
pressure washer immediately and consult a
service technician.
H3612 OPERATIONS
These units are equipped with a 12 volt burner.
This burner is powered by both a rectifier on the
Honda engine and the battery installed on the
pressure washer when operating in the hot water
mode. The system can operate for 12 hours in the
hot water mode before the battery needs to be
recharged. This 12 hours can be continuous or
through periodic operation. When the battery is
depleted the burner will no longer run. Recharge
the battery with a slow trickle charger with
automatic shut-off. An overnight charge should
completely recharge the battery. The battery will
also recharge when operating as a cold water unit;
the rectifier of the Honda engine provides a charge
to the battery. However, this process is much
slower than a battery recharger.
SHUT DOWN INSTRUCTIONS
For gas powered pressure washers
:
1 Move throttle lever to idle position, the turn
engine switch to off. Shut off gas to the carburetor
by moving valve to the left.
For electrically powered pressure washers:
1. Turn motor switch to off.
After turning the pessure washer off:
2. Turn water source off.
3. Squeeze gunjet trigger to relieve remaining
pressure in the high pressure hose.
