Safety instructions

Your safety and the safety of others are very important. We have provided important safety messages in this manual and on the water pump. Please read these
messages carefully. A safety message alerts you to potential hazards that could hurt. You or others. Each safety message is preceded by a safety alert symbol.
Warning: In some cases, the engine is delivered without engine oil. Please add the correct amount of engine oil before using the machine.
Water Pump Safety
• Please read the manual carefully before using the gasoline water pump set.
• Before operating, perform the pre-operation inspection to make your operation on the water pump safer.
• For the sake of safety, be sure not to pump inflammable or corrosive liquids (such as gasoline or acid). Similarly, be sure not to pump corrosive such as sea-
water, chemical solutions, alkaline liquids (used engine oil, alcohols and honey).
• Locate the water pump on a firm and levelled ground. A sloped or overturned water pump may result in fuel spilled out
• Operate the water pump in a well-ventilated place without fire resources and keep the water pump at least one meter from other devices.
• Because touching hot parts of the engine may get severe burns when operating the water pump keep children and pets far away from the operating site.
• Master the method to quick stop the water pump; learn manipulation control devices.
Using the water pump without following the instructions in the manual must be avoided.
Warning: Gasoline is extremely flammable and explosive in certain conditions.
Filling gasoline in a well-ventilated place with a stalled engine. In gasoline filling and storage sites, be sure there are no smoking and fire resources such as
flame, fire spark and so on.
Do not spill gasoline out of the tank. After filling, make sure to tighten the fuel tank cap.
When filling, avoid spilling gasoline out, for spilled gasoline and gasoline vapour is prone to ignite. Once gasoline is spilled out, make sure to wipe it up before
operation.
Do not run the engine in an enclosed room and poor-ventilated place, since exhaust emissions from the engine contain toxic carbon monoxide (CO), which may
make people lose consciousness even lead to death.
Safety label location
Safety labels indicate potential danger to result in severe accidents. Read carefully the instructions here with respect to safety labels and safety precautions. If
safety labels become illegible or lost, contact your dealer for a new one.

Pre-operation preparation

Connecting the water inlet pipe
Use commercially available hose, hose joint and clamp. The water inlet hose must be of continuous and be non-folded. The length of the hose should be as
the same as or not more than that required. In this case, not far away from the surface of water supply, the water pump will arrive its optimal performance.
Self- suction time varies with the length of the water inlet hose with a hose clamp, shown in the diagram below.
Caution: Before pumping, install the filter securely to the end of the water inlet hose. The filtrates any impurity, which may produce passage jam to damage
impellers.
Be sure to install the hose joint and clamp well so as to prevent from air leaks and pumping performance drop; loose water inlet hose will decrease the water
pump performance and self-suction ability.
Note: tighten the hose clamp to avoid falling off under high pressure.
Connecting the water outlet hose
Use commercially available hose, hose joint and clamp. A short hose with a big diameter is the best. A long hose with small diameter will increase flowing
resistance and decrease the power output of the water pump.
Engine oil and fuel check
Picture C: (1) Filler Cap/Dipstick (2) Upper Limit (3) Lower Limit
Picture D: (1) Maximum Fuel Level
The quality of the engine oil is one of the key factors in deciding engine performance and service life. Not apply filthy engine oil or vegetable oil.
Be sure to check engine oil level with the engine stalled and stand vertically in level ground.
Use 4-stroke gasoline engine oil or engine oil equivalent in quality with SF, SG from API. Oil velocity varies with average temperature, so engine oil with proper
velocity in accordance with your region temperature.
Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.
a) Remove the oil filler cap/dipstick and wipe it clean,
b) Insert the filler cap/dipstick into the oil filler neck, but do not screw it in,
c) If the level is low, fill to the top of the oil filler neck with the recommended oil.
Notice: Running the engine with insufficient oil can cause serious engine damage.
1. Remove the filler cap check fuel level.
2. Refill the tank if the fuel level is low. Do not fill above the shoulder of the fuel strainer.
