♦ ELECTRICAL: Connect the machine to an
electrically grounded circuit that is fuse or
circuit breaker protected. Do not use any type
of adapter. If the correct type of receptacle is
not available, have one installed by a qualified
electrician.
♦ OIL LEVEL: Check the oil level in the water
pump.
♦ BELT (if so equipped): Make sure the belt
tension and condition is as specified in
MACHINE MAINTENANCE.
♦ METERING VALVE (if so equipped): Make sure
the metering valve is closed before
operation. If air enters the system through this
valve, poor performance and machine damage
will occur. Refer to the metering valve insert
for proper operation.
♦ WATER SUPPLY: This machine must have a
water supply meeting or exceeding the
maximum discharge volume specified in the
machine specifications, and a minimum water
inlet pressure of 40PSI / 12.1KGM.
♦ LIME: Water containing large amounts of lime,
calcium or other similar materials can produce
a coating on the inside of the impact nozzle or
spray tip and coil pipe.
♦ FLOAT TANK: Check the float tank (if so
equipped) to assure it is full and the float
tank valve shuts off securely.
♦ BALL VALVE: Check the position of the ball
valve (if so equipped) on outlet line of the float
tank assuring that it is in the open position.
1. GUN ASSEMBLY IN HAND: (on trigger gun
models hold the trigger gun valve in open
position) and with a good flow of water turn
the switch to pump position.
CAUTION: A good flow of water must be Flowing
from the end of a gun for 30 seconds, before
proceeding. Lack of water can cause damage to
the water pump and like components.
CAUTION: On a machine equipped with a
trigger gun valve, if the trigger gun valve
remains in the closed position
for more than 3 minutes, water pump damage
may occur.
2. To CLEAN:
A. Start on the lower portion of the area to be
cleaned and work up using long, even,
overlapping strokes.
B. Dirt is generally removed easily if grease
and/or oil is not present. However if grease
and/or oil are present, hot water and
chemical will accelerate in the cleaning
process.
3. TO APPLY CHEMICAL:
CHEMICAL: Use factory recommended
chemicals for best cleaning action and for
extended pump life. Contact your dealer for
chemicals available. Follow instructions on
chemical container.
Mix chemicals per label instructions. Use
necessary safety precautions.
A. Insert chemical screen into chemical
container
B. Adjust metering valve (if so equipped).
C. If the gun assembly is equipped with
variable or multiple nozzle assembly,
adjust as desire.
4. TO RINSE:
A. If the machine is equipped with a panel
mounted metering valve, close the chemical
metering valve (if so equipped). NOTE: It is
advisable to dip the chemical screen in a
container of clean water and open the valve
1 minute to clean the valve of any remaining
residue.
B. If the gun assembly is equipped with
variable or multiple nozzle assembly, open
and close to clean nozzle of any remaining
residue.
C. After a clear flow of water is noted from the
end of the wand, start from the top, working
downward using long, overlapping
strokes.
SHUT-DOWN
1. Turn the pump switch to the off position.
2. Turn off the water supply.
4. If freezing conditions may exist, refer to
STORAGE in MACHINE MAINTENANCE.
