the nozzle to make sure it is seated properly.
Operating Instructions
| STEP 1: Connect garden hose to the cold water source and turn water on
completely. Never use hot water.
---|---
| STEP 2: Trigger the spray gun to eliminate trapped air then wait for a
steady flow of water to emerge from the spray wand. Then install nozzle.
| STEP 3: Turn machine on by flipping switch at front of machine.
The five color-coded quick connect nozzles provide a wide array of spray
widths from 0° to 40° and are easily accessible when placed in the convenient
rubber nozzle holder, which is provided on the front of the machine.
NOTE: For a more gentle rinse, select the white 40° or green 25° nozzle.
To scour the surface, select the yellow 15° or red 0° nozzle. To apply
detergent select the black nozzle.
WARNING! Never replace nozzles without engaging the safety latch on the spray gun trigger.
Selection of high or low pressure is accompanied by turning the handle.
NOTE: High pressure nozzle must be inserted at end of wand to obtain high
pressure. To apply soap read operator’s manual.
Detergent and General Operating Techniques
WARNING: Some detergents may be harmful if inhaled or ingested, causing
severe nausea, fainting or poisoning. The harmful elements may cause property
damage or severe injury.
STEP 1: Use detergent designed specifically for pressure washers.
Household detergents could damage the pump. Prepare detergent solution as
required by the manufacturer. Fill a container with pressure washer detergent.
Place the filter end of detergent suction tube into the detergent container.
STEP 2: Apply safety latch to spray gun trigger. Secure black detergent nozzle
into quick coupler.
NOTE: Detergent cannot be applied using the Yellow nozzle.
STEP 3: With engine running, pull trigger to operate machine. Liquid detergent
is drawn into the machine and mixed with water. Apply detergent to work area.
Do not allow detergent to dry on surface.
IMPORTANT: You must flush the detergent injection system after each use
by placing the suction tube into a bucket of clean water, then run the
pressure washer in low pressure for 1-2 minutes.
Thermal Pump Protection
If you run the engine on your pressure washer for 2-3 minutes without pressing
the trigger on the spray gun, circulating water in the pump can reach high
temperatures. When the water reaches this temperature, the pump protector
engages and cools the pump by discharging the warm water onto the ground. This
thermal device prevents internal damage to the pump.
Cleaning Tips
Pre-rinse cleaning surface with fresh water. Place detergent suction tube
directly into cleaning solution and apply to surface at low pressure (for best
results, limit your work area to sections approximately 6 feet square and
always apply detergent from bottom to top). Allow detergent to remain on
surface 1-3 minutes. Do not allow detergent to dry on surface. If surface
appears to be drying, simply wet down surface with fresh water. If needed, use
brush to remove stubborn dirt. Rinse at high pressure from top to bottom in an
even sweeping motion keeping the spray nozzle approximately 1 foot from
cleaning surface. Use overlapping strokes as you clean and rinse any surface.
For best surface cleaning action spray at a slight angle.
Recommendations:
- Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.
- If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface.
- Keep the spray nozzle a safe distance from the surface you plan to clean. High pressure wash a small area, then check the surface for damage. If no damage is found, continue to pressure washing.
CAUTION – Never use:
- Bleach, chlorine products and other corrosive chemicals
- Liquids containing solvents (i.e., paint thinner, gasoline, oils)
- Tri-sodium phosphate products
- Ammonia products or Acid-based products
These chemicals will harm the machine and will damage the surface being cleaned.
Rinsing
It will take a few seconds for the detergent to clear. Apply safety latch to
spray gun. Remove black soap nozzle from the quick coupler. Select and install
the desired high pressure nozzle.
NOTE: You can also stop detergent from flowing by simply removing
detergent siphon tube from bottle.
Handheld Wireless Operating Instructions
For Wireless Remote Control Operation
Step 1: Push the control panel pump switch to the “ON” position (first click).
With the switch in this position the wireless remote is ready for use.
Step 2: To control pressure washer in remote mode, press transmitter button 1
to turn pump “ON”. Press transmitter button 2 to turn pump “OFF”. Pump can
also be controlled manually by pressing the control panel pump ON/OFF switch.
Chemical 1: To start chemical 1 flow, press transmitter button 3. The green
indicator light will illuminate when chemical 1 is in use. Press button 3
again to stop chemical 1 flow.
Chemical 2: To start chemical 2 flow, press transmitter button 4. The green
indicator light will illuminate when chemical 2 is in use. Press button 4
again to stop chemical 2 flow.
When machine is not in use, push control panel pump switch to the “OFF”
position. Store transmitter on the transmitter bracket.
NOTE: Normal operating range for the transmitter is about 500 feet
interference-fee (line of site); 300 feet light interference (inside
warehouse, pallet shelves); and 100 feet heavy interference (through concrete/
stone walls, metal doors). If greater range is desired, the antenna can be
mounted at a separate location.
This requires a longer cable – RG-58-U coaxial with BNC end connectors.
Transmitter/Receiver Communication Set-up at Factory
Programming communication between the receiver and transmitter requires the
removal of the receiver enclosure lid. The receiver must have 120V power. This
process utilizes the Function/Select buttons on the main panel control board
(PCB) of the receiver (See Figure below). A number of colored LED’s are used
to indicate various steps in the programming process (See Figure below). It is
recommended that this process is not done while wired to the machine.
Receiver Programming LED’s and Programming Switches
The T60-04CRV receiver programming process is as follows: While programming,
make sure there are no other transmitters are transmitting in the area.
- Press the Function button once to select the “Learn Code” mode. (#6 Red LED lights, you have approximately 5 seconds to make the next selection.)
- Press the Select button once and then press any button on the transmitter and hold. (#6 Red LED will blink on/ off three times and go out. After releasing the transmitter button, the relays will respond to the appropriate buttons (Button 1/R1; Button 2/R2; Button 3/R3; Button 4/R4); and the #6 red LED will blink on/off indicating that one or more adjustable codes have been learned by this receiver.
- Press and hold the Select button for 6-8 seconds so the yellow LED is on solid. (#7 Yellow LED lights)
NOTE: This step is only completed when establishing the first transmitter communication.
The receiver is now programmed to the desired transmitter.
Shutting Down And Clean-Up
