STP SERIES PRESSURE WASHER
OPERATOR’S MANUAL
7
Shark STP • 97-6153 • Rev. 7/03
READ OPERATOR’S
MANUAL THOROUGHLY
PRIOR TO USE.
CAUTION
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for proper
power supply using a volt meter.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away from walls should be adequate.)
Water Source:
The water source for the pressure washer should be
supplied by a minimum 5/8" I.D. garden hose with a city
water pressure of not less than 30 PSI. If the water sup-
ply is inadequate, or if the garden hose is kinked, the
attached pressure washer will run very rough and the
burner will not fire.
Connection:
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon tape
to avoid water leaks. (See Component Identification).
Venting:
Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes car-
bon buildup, which affects the operation, and increases
maintenance on the coil. If a stack must be used, refrain
form using 90° bends. If the pipe can not go straight up
then use only 45° bends and go to the next size pipe.
The overall pipe length must not exceed 6 feet in length.
STARTING AND OPERATING
INSTRUCTIONS
To Start:
1.
STOP!
Read operator's manual
before operating. Failure to read
operation and warning instruc-
tions may result in personal in-
jury or property damage.
2. Connect water supply hose and
turn on water.
3. Check fuel tank and pump oil
levels.
4. Connect high pressure hose to discharge nipple by
sliding quick coupler collar back. (If detergent is to
be applied, insert a detergent injector as shown in
Component Identification).
5. Insert quick coupler onto discharge nipple and se-
cure by pushing quick coupler collar forward.
6. Securely attach the desired high pressure nozzle into
wand coupler as described in steps 4 and 5.
7. Connect the power cord into the proper electrical
outlet, then push in the GFCI reset button (Refer to
serial plate for information.)
8. Grip spray gun handle securely and pull trigger. Then
turn variable pressure control handle counterclock-
wise.
9. Turn switch to pump position. When a steady stream
of water flows from the spray gun and wand, the
machine is ready for cold water cleaning by turning
the variable pressure control handle clockwise to
raise the pressure.
10. For hot water washing, turn the switch to the burner
position. (The burner will light automatically when
the trigger on the spray gun is pulled.)
To Stop:
1. If using the detergent injector, place the suction line
in a bucket of water allowing detergent to be flushed
from system.
2. Turn STP burner switch off and continue spraying
water, allowing the water to cool.
3. After water has cooled to less than 100°F, turn the
attached pressure washer off.
4. Turn garden hose water off. Open the spray gun to
relieve remaining pressure.
5. Protect from freezing.
