3. Safety Guidelines
This manual contains information that is important for you to know and understand. This information relates to protecting YOUR
SAFETY and PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the symbols below. Please
read the manual and pay attention to these sections.
Improper maintenance and operation are responsible for the majority of accidents involving gas pressure washers. The largest
portion of these could be prevented by recognizing the basic safety rules and precautions. Most accidents can be avoided if the
operator recognizes a potentially hazardous situation before it h 叩 pens and by observing appropriate safety rules and procedures
as outlined in this manual. Basic safety precautions are outlined in the SAFETY portion of this manual and throughout the text in
this manual where a potential hazard might occur. Hazards that MUST be avoided to prevent serious injury follow headers marked
DANGER or WARNING. These same precautions are placed as labels on the tool itself. NEVER use this pressure washer for
applications that are NOT specified in this manual.
WARNING- READ AND FOLLOW ALL INSTRUCTIONS
• Failure to follow all instructions in this manual may result in severe
personal injury or death. Keep this manual and refer to it for Safety
Instructions, Operating Procedures, and Warranty.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious
WARNING indicates a potentially hazardous
situation which, if not avoided, could result in death
or serious injury.
CAUTION used without the safety alert symbol indicates

be inhaled.
ALWAYS use the only fluids specifically recommended for high pressure washers.
NEVER operate unit in a location occupied by humans or animals.
NEVER use chlorine bleach or any other corrosive compound.
ALWAYS shut off engine and allow it to cool a least 2minutes before adding fuel to the tank.
ALWAYS use care in filling tank to avoid spilling fuel. Move pressure washer away from fueling area before starting engine.
ALWAYS Keep maximum fuel level below top of tank to allow for expansion.
ALWAYS operate and fuel equipment in well ventilated areas free from obstructions. Equip areas with fire extinguishers suitable
for gasoline fires.
ALWAYS keep pressure washer a minimum of four feet away from surfaces (such as houses, automobiles, or live plants) that
could b e damaged from muffler exhaust heat.
ALWAYS store fuel in an OSHA approved container, in a secure location away from work area.
NEVER spray flammable liquids
NEVER operate pressure washer in an area containing dry brush or weeds.
•Keep the area of operation clear of all persons, particularly small children, pets and obstacles.
•Do not operate the product when fatigued or under the influence of alcohol or drugs. Stay alert at all times.
•If engine does not start after two pulls, squeeze trigger of gun to relieve pump pressure. Pull starter cord slowly until
resistance is felt Then pull cord rapidly to avoid kickback and prevent hand or arm injury.
•Do not overreach or stand on an unstable support.
•The cleaning area should have adequate slopes and drainage to reduce the possibility of a fall due to slippery surfaces.
•Be extremely careful if you must use the pressure washer from a ladder, scaffolding, or any other similar location.
Beware of kick-back force and the sudden torque on the spray gun assembly when operating the trigger. Firmly grasp spray
gun with both hands to avoid injury when spray gun kicks back.
DANGER- RISK TO BREATHING
• Running engine gives off carbon monoxide, an odorless, colorless, poison gas.
• Breathing carbon monoxide can cause nausea, fainting or death.
• Some chemicals or detergents may be harmful if inhaled or ingested, causing
severe nausea, fainting or poisoning.

NEVER attach or remove wand or hose fittings while system is pressurized.
NEVER use a spray gun which does not have a trigger lock or trigger guard in place and in working order.
ONLY USE hose and high pressure accessories rated for pressure higher than your pressure washer's p.s.i.
To relieve system pressure, shut off engine, turn off water simply, and pull gun trigger until water stops flowing.
DO NOT allow CHILDREN to operate pressure washer.
NEVER repair leaking connections with sealant of any kind. Replace o-ring or seal.
NEVER connect high pressure hose to nozzle extension.
DO NOT secure spray gun in open position.
DO NOT leave spray gun unattended while machine is running.
ALWAYS be certain spray gun, nozzles and accessories are correctly attached.

can cut through skin and its underlying tissues, leading to serious
injury and possible amputation. Spray gun traps high water
pressure, even when engine is stopped and water is disconnected,
which can cause injury.

Keep children away from the pressure washer at all times. They may not be able to recognize the hazards of this product.
DO NOT let hoses come in contact with very hot engine muffler during or immediately after use of your pressure washer.
AVOID hot exhaust gases.
NEVER operate pressure washer without protective housing or covers.
DO NOT wear loose clothing jewelry or anything that may be caught in the starter or other rotating parts.
Tie up long hair and remove jewelry.
ALWAYS wear safety goggles when using this equipment or in vicinity of where equipment is in use.
Before starting the pressure washer, be sure you are wearing adequate safety goggles.

NEVER pull water supply hose to move pressure washer. This could damage hose and/or pump inlet.
DO NOT use hot water, use cold water only.
NEVER turn water supply off while pressure washer engine is running or damage to pump will result.
DO NOT stop spraying water for more than two minutes at a time. Pump operates in bypass mode when spray gun trigger is
not pressed. If pump is left in bypass mode for more than two minutes internal components of the pump can be damaged.
Before starting pressure washer in cold weather, check all parts of the equipment to be sure ice has not formed there.
DO NOT use the pressure washer if excessive noise or vibration is present. Have it repaired immediately.
DANGER-- RISK OF HOT SURFACES

5.3 General Technology
PSI: Pounds per square inch -common unit measure used for water pressure, air pressure, hydraulic pressure and pounds of force.
GPM: Gallons per minute (liters per minute [metric]) -common unit measure used for flow rate of water.
Bypass Mode: In bypass mode, high pressure pump recirculates water because spray gun trigger is not pulled.
High Pressure Washer Pump
1. Pump Model & Serial Number: It contains the year, month and day of production, and can track the batch of materials
assembler and tester. Please provide the serial no. along with the pump model and version when ordering spare parts and
reporting any issues of concern.
2. Pressure Adjusting Knob: To raising or reduce the pressure by turn the knob.
3. Detergent Injector: Use to siphon detergent or other pressure washer chemicals into the low pressure stream.
4. Water Outlet Connector: To connect high pressure hose.
5. Water Inlet With Filter Screen: Connect garden hose here, and always have the filter screen present in it.
6. Red Shipping Plug Attached With Vent Plug: the pump is ship with red shipping plug to prevent oil leaking during
transportation.
Replace with the attached vent plug before using.
7. Thermal Relief Valve: Cycles water through pump when water reaches 125-155°F (50-68°C). Warm water will discharge from
pump onto ground. This valve can prevent internal pump damage.
8. Pulse Control Valve：Pulsation makes the hose vibrate, helping the jet go longer distances and around tight bends easier.
The pulse control valve is located on the front of the pump. Simply turn the valve on to engage the pulse.
