FAQs

Gas Lawn Mowers

Newly arrived gas lawn mowers won't start

1. Check the oil - a new mower will not start on arrival. Sometimes it is because too much or too little oil has been added. Please check with the dipstick after adding oil.

2. Check starter cable - Please check that the starter cable connector has not fallen off.

3. Check spark plugs - Check for loose spark plug connections.

4. Check the engine for oil ingress - The engine may have too much oil ingress during repeated starting and the spark plug cannot produce a good spark, resulting in the machine not starting. Please open the air filter, check for gas, remove the filter element and let it sit for about 30 minutes.

5. Press the ignition bulb - When starting the engine for the first time, please press and release the ignition bulb 3 times.

The machine will not start after a period of use

1. check the oil - the mower will not start. Sometimes this is because too much or too little oil has been added. Check with dipstick after adding oil.
2. Check starter cable - Check if the starter cable connector has fallen off.
3. Check the spark plug - Please check if the spark plug connection is loose; whether it is carbonized and cannot be started, the spark plug will form a layer of carbon on the metal surface after using for a long time, which will affect the ignition effect. Generally speaking, as a household tool, a product that has been used for one or two years will not build up carbon unless very poor gasoline is used. It can usually be cleaned with a detergent. If you can't get rid of it, we will replace the spark plug for free.
4. Check whether the engine is oiled - the engine may be oiled too much during repeated starts, and the spark plug cannot produce a good spark, resulting in the machine not starting.
5. Please open the air filter, check whether there is gasoline on the filter, if so, you need to replace the filter (we can send you a replacement or free of charge), remove the filter, take out the sponge, and dry the gasoline in the sun; then install the dried filter before starting the engine, if the filter is very wet it will prevent the air from entering the cylinder, and the condition of stalling and not being able to start will occur.
6. Check whether the carburetor is clogged or not, you can clean the carburetor (if the engine is not used for a long time, the gasoline in the carburetor will evaporate and concentrate into a gel, which will clog the carburetor).
7. Press the ignition bulb - When starting the engine for the first time, press and release the ignition bulb 3 times.

Gasoline engine won't start

The machine can be pulled, but can not start, mainly for the following reasons:

1. ignition problems, that is, bad spark plugs, carbon deposits may affect the ignition, you can remove the spar.plug to check, but also available gasoline to clean the burnt parts.

2. fuel line problems, from the gasoline tank to the fuel line, carburetor whether the oil supply is smooth. Check whether the fuel line valve is open; loosen the carburetor screws, release a small portion of gasoline, so that the carburetor can be cleaned.

3. Circuit problems, check whether the flameout switch is intact, whether it is in the starting position.

4. Oil problems, many gasoline engines with oil alarm device, that is, no oil, oil is too low, the engine can not start, so spin down the oil scale, check whether the oil is enough.

5. air supply problems, check whether the air filter is clean, if very dirty will affect the air supply, resulting in failure to start. So remove the air filter and clean or replace it.

Can not be started because the machine can not be pulled, mainly due to the following reasons:

1. start pull disk failure: remove the start pull disk, pull the start pull rope, check:
2. 1, the rope can be pulled; 2, the rope can be pulled under the circumstances, the pawl can be extended.
If the two are normal, it is good to start pulling the disk; as long as there is an abnormality, it shows that the pulling the disk is bad, you need to replace the pulling the disk assembly.
3. Cylinder block internal embrace, stuck (may be due to the cylinder block internal oil or lack of oil running caused by), need to replace the engine.

Oil leakage

1. The engine model has a fuel pipe connected to the air filter element at the fuel tank port, if the gasoline is overfilled, the gasoline will flow into the air filter element through this pipe, thus leaking oil.

Handling method:‚φGasoline must not be added to the full tank mouth;

‚Ď°Open the filter element, take out the sponge and dry the gasoline in the sun;

‚ĎĘInstall the dried filter element and then start the engine. If the filter element is wet, it will prevent the air from entering the cylinder, and you will not be able to start the engine.

2. Loose carburetor screwsLoosen the oil drain bolt, then check the dipstick to drain some of the oil. The drain bolt number in the owner's manual is 303020518. you can find the enclosed owner's reference manual.

3. Seal failureIf oil leakage occurs when the engine is shut down, faulty seals (bushings, o-rings, seals and washers) should be the most likely cause.

Mower starts but doesn't cut grass

Possible faults:

‚φ Horizontal shaft (product model H series)
1.Belt damaged or detached, need to repair or replace
2.Tensioner pulley is badly worn, tensioner pulley tension spring is broken or detached, etc., need to be repaired or replaced
3.The blade is loose, and the connection with the blade holder is slipping. Reinstall the blade and blade holder, and tighten the blade bolts.
4.The flat key that connects and positions the blade holder and engine output shaft is broken or peeled off, resulting in the output shaft not being able to drive the blade to run together. The output shaft needs to be replaced.

‚Ď° Vertical shaft (Product model R series)
1. The blade is loose and the connection with the knife seat slips. It is necessary to reinstall the blade and the blade holder and tighten the blade bolts.
2. The flat key that connects and locates the blade holder and the engine output shaft is broken or peeled off, resulting in the output shaft not being able to drive the blade to run together, and needs to be replaced.

Mower once started, it mixes gas and oil together

Adding too much oil or starting the machine after it has been tilted can cause the oil and gasoline to mix together, creating smoke, see below for how to deal with this:

Starting bulb will not deliver gas to the engine:

The fuel line connecting the starter bulb to the carburetor is not connected, cracked, etc., and needs to be reconnected or replaced.

White smoke
Usually smoke is produced because
It is because the engine is not in a horizontal position, causing the oil to enter the cylinder and burn, resulting in smoke. Therefore, the engine should not be tilted too much when working.
Solution:
1, remove the spark plug, wipe the head metal parts clean;
2„ÄĀCheck the oil dipstick to see if the oil level is in a reasonable range; if the oil level is appropriate, continue to start the engine and make it run for a period of time to see if the smoke is reduced or disappears.

Black smoke

Generally, black smoke is caused by insufficient combustion and difficult air intake.

SolutionÔľö

1. Remove the spark plug and wipe the metal part of the head clean; disconnect the oil circuit of the machine and pull the starter by hand to discharge the residual waste oil in the cylinder.

2.Open the air filter, take out the sponge inside and clean the accumulated gasoline inside before installing and using.

Abnormal/disordered self-propelled function

Solution:

1, Remove the belt cover inside the base and check if the belt is intact (there is a video on Amazon);

2„ÄĀDisassemble¬†the¬†rear¬†wheel¬†to¬†check¬†whether¬†the¬†transmission¬†gear¬†is¬†intact;.

3„ÄĀIf¬†you¬†exclude¬†the¬†above¬†problems,¬†it¬†is¬†the¬†problem¬†of¬†the¬†self-propeller,¬†we¬†will¬†apply¬†for¬†repair¬†and¬†replace¬†the¬†self-propeller¬†for¬†you.

Or Typically, if the self-propulsion function stops working, it is related to the drive belt coming off the pulley system under the round deck housing.

How to replace a bad self-propulsion brake control cable

1. remove the control cable end from the operating lever and top tube; and

2. Loosen the screws on the rear seat and base to separate the rear seat from the base; and

3. Remove the other end of the control cable from the connection of the self-propelled vehicle.

4. Pull out the removed cable from the hole of the rear seat.

5. Install the new control cable in the order of 4→1 . After the installation is completed, you need to adjust the tubular thread structure on the cable to adjust the tightness of the cable.

Self-propelled speed can not be adjusted

The gasoline mower is not equipped with speed adjustment function, the self-propelled speed of the mower is in the range of 3.6~4.1km/h.

Loud noise, shaking violently, even stop running

1. Whether it touches hard objects such as stones, water pipes, etc. during the mowing process;

2. The grass collection port is blocked, and it can't get out the broken grass, which causes the blade to be overloaded;

3. The moving parts rubbing against the immovable parts due to external force.

Mower drive belt and belt cover installation

1. First remove the blade bolts as well as the blade, belt protection cover and adapter so that the pulley can be fully accessed.

2. you must pull the belt over the pulley first and then pull the drive assembly securely.

3. Next, turn the unit back onto the wheels and push the unit forward to turn the pulleys and the belt will be secured to the pulley system. 

4.Turn the unit back onto its side and then reattach the adapter, blade and bolts to the unit accordingly. Tighten the bolts and you are ready to go!

How to clean the carburetor

In the following steps:

1. disconnect the fuel line from the carburetor to the fuel tank;

2. remove the carburetor and loosen the drain bolt at the bottom to release any residual gasoline;

3. Remove the main internal fittings (gauge hole, float, fuel nozzle);

Clean the main fittings and oil lines with a special carburetor cleaner (I can send you a video of cleaning the carburetor if needed).

How to drain gasoline and oil

A.Drain gasoline:

1.Disconnect the fuel line from the carburetor to the fuel tank;

2. Remove the oil drain bolt at the bottom of the carburetor and drain the residual gasoline.

B. Oil Drain.

1. Unscrew the oil cork and tilt the machine in the direction of the cork so that the oil is discharged from the cork opening, or use a pumping device to pump out the oil.

How to remove and replace the pull-tab assembly

Cordless Products

Battery cannot be charged

The Power Smart is equipped with a 40V charger with a maximum output voltage of 42VDC and a rated output voltage of 36VDC, and an 80V charger with a maximum output voltage of 84VDC and a rated output voltage of 72VDC. 

The maximum output voltage of 80V charger is 84VDC and the rated output voltage is 72VDC.

Use a multimeter to measure the voltage at the output of the charger, if it is lower than the above value, it means that the charger is faulty; if it is normal, it means that the battery pack is faulty. Need to replace the battery.

The battery does not last long, even only 10-20 minutes, but it takes a long time to charge.

1. Charging time:

It takes about 120-150 minutes to fully charge a 40V battery pack configured for Power Smart products; it takes about 80-90 minutes to fully charge an 80V battery pack.

2. Range time;

Range time is greatly affected by the actual use of the situation, if the site grass is deep and thick, then the actual use of time will be relatively short. If the site grass is shallow and sparse, then the actual use of time is relatively long. If the battery lasts only a few minutes, then consider replacing the battery pack.

The battery cover will not stay open to allow for insertion of the battery and is difficult to insert and remove, requiring multiple attempts.

1. The battery cover routinely stays closed, which prevents rain and broken grass from entering the battery compartment and damaging the battery.

2.The battery pack is inserted into the battery compartment in the required direction, if the direction is wrong, it will be impossible to insert and difficult to remove.

The correct way to install and remove the battery pack

Installation of the battery: the charging electrode of the battery to the electrode of the battery compartment, slide along the battery base into place, squeeze hard, you will hear a clear "click" sound, then the correct installation is complete.

Remove the battery: Press the battery limit button to eject the battery from the battery compartment, then pull the pack outward along the battery base until it is removed.

How to adjust the speed

Power Smart lithium self-propelled mowers are equipped with a self-propelled speed adjustment function, you can adjust the speed knob on the panel to control the self-propelled speed.

Flame out problem

1. Normal stalling: release the operating switch, pull out the safety key and battery pack.

2. Overload/overheat protection flameout: When the mower is in use and the blade hits hard obstacles or thick grass, the working current increases instantly and exceeds the set overload protection current, the mower will stop temporarily due to overload. At this time, you need to re-insert the safety key and battery pack, and start the work again.

3. Abnormal flameout: If the mower stalls several times during normal operation, the internal controller is considered to be faulty and needs to be replaced.

The bag does not collect grass, it just sprays it on the lawn

1. Power Smart mowers are equipped with a rear discharge, side discharge, and shredding function. When both the side discharge and rear discharge functions are used at the same time, most of the shredded grass will be sprayed out of the side discharge ports, and the amount of shredded grass collected in the grass bag will be greatly reduced.

2. When the rear discharge port is clogged, the grass collected in the grass bag will be reduced and the chopped grass that is cut will be left on the lawn, so it is necessary for us to stop the machine and clear the clogged grass from the rear discharge port.

<40v lawn mower + leaf blower combo set>

It works fine on the blower but when I try to use it on the lawnmower mower it doesn't start

1. check that the battery pack is properly in place

2. safety key is inserted in place

3. Make sure the battery pack is sufficiently charged

4. Follow the instructions for proper operation

5. If all of the above are OK, the internal wiring or controller of the machine is faulty and needs to be replaced.
