Why is it important to keep the cooling fins clear? (2-stroke tiller)
Here some important information about the Cylinder exhaust port and cooling system .
All cooling fins must be kept clear in order for the engine to operate efficiently.
Here you find the cooling fins on the exhaust port of your Mantis 2-stroke tiller.Back to Index
Carburetor information (2-Stroke Mantis tiller)
In accordance with current EPA Regulations and CARB requirements, limiter caps have been installed on the high and low screws of the carburetor. Removal of these caps by anyone other than an authorized Mantis dealer will void your warranty.
Replacement carburetor, rebuild kits and gasket/diaphragm kits are available. Please contact us directly.
To order parts, you will need the SV# of the engine.

How to locate the SV number of your 2-cycle tiller engine?
When ordering parts for your Mantis 2-cycle tiller, you may need to locate the SV number of your engine. The SV number is located between the gas tank & the carburetor, behind the gas line, on a black and silver tab on the silver engine housing.
It will consist of the letters “SV,” a number and another letter.
Examples: SV4A, SV4B1E.

Why is my engine bogging down when I give it full throttle?
Your air filter or your spark arrestor (muffler screen) may be clogged and not allowing the engine to breathe properly. This will cause it to act as if the choke is on and bog down under a load.
Replace your air filter and check the muffler screen to make sure it is clean.

Why is my 2-cycle engine getting really hot?
You may not have enough oil in your gas mixture to properly lubricate the engine.
Always make sure you use the proper 50:1 mixture ratio. Convenient, pre-measured bottles of premium 2-cycle engine oil are available via our online shopping. Shop here : 2 stroke oil for Mantis tillers.
Also, there may be a buildup of dirt or debris on the cooling fins of the engine; make sure they are kept clean.Back to Index
My rope pulls out with no resistance, why won’t it turn the engine?
There may be some dirt or debris in your pawl catcher assemply causing them to stick.
Remove the 4 screws on the starter assembly and lift it off the tiller. Looking down on the tiller, on top of the flywheel, you will see a gold-colored dish with 2 black levers inside. The levers are called pawl catchers. Use a piece of 80-grit sandpaper and slide it under each pawl. Move the pawl back and forth 10-12 times. This will clean the debris out and smooth the pawls. Replace the starter assembly.Back to Index
How often should I replace my fuel filter?
Your fuel filter should be replaced every 3 months or 100 hours of use.Back to Index
Should I replace the air filter on my Mantis Gas Tiller?
Clean air filters will assist in ensuring optimum performance for your Mantis Gas Tiller. The filters do not clean very well and once dirt infiltrates the fibers of the air filter, the possibility of your engine seizing from dirt ingestion increases.

Why should I walk backwards when using the Mantis Tiller?
Because of the design of the blades (tines) and the light weight of the machine, the tiller digs into the soil by using resistance.
The Mantis tiller is designed to be used in a fashion very similar to running a vacuum cleaner.
It’s not necessary to continuously walk backward, many users find it comfortable to stand in one spot, allow the tiller to walk forward and then slowly pull it backwards, allowing it to dig into the soil.
Then go forward at a different angle and pull it back again.
If you prefer, it will also work to walk slowly backward the length of your garden. By tilling this way, you don’t have to walk through your freshly tilled soil.Back to Index

How do I maintain my Mantis tines?
After each use, remove and clean the tines.
Then spray both the tines and the tine shaft with WD-40 or some other light lubricant to protect them from rust.
This will also prevent the tines from “freezing” onto the tine shaft.

Can I use any lithium grease in my transmission?
No, you cannot; you must use lithium 0 weight grease, double-zero weight is too free-flowing and may not lubricate the gears properly.

Why don’t I see a spark on my spark plug when I test it, I think my coil is bad?
Most likely the coil is not bad on your machine. It is rare that a coil can fail because it is completely sealed and electronic.
The coil is a very low sparking one and can only be properly tested with a 3-point ignition tester.
You will not see or feel a spark by grounding the plug. We recommend having the coil tested by your local Mantis dealer.Back to Index
How do I empty my engine to store it for the winter?
Do not store your tiller with fuel still in it. Even under ideal conditions, stored fuel containing ethanol or MTBE can start to go stale in 30 days. Since stale fuel has a high gum content, it can clog the carburettor. This, in turn, will restrict the fuel flow. When you’re ready to store your tiller, or will not be using for more than 2 weeks, drain the fuel tank completely.
Next, restart the engine to make sure no fuel is left in the carburettor. Run the engine until it stops. This will prevent gum deposits from forming inside the carburettor and possible engine damage.Back to Index
Why won’t my Mantis tiller start – it has been stored away for a few months?
You may have to clean the carburettor of old fuel or replace the gaskets and diaphragms. If the tiller is stored with even a small amount of old fuel (older than 30 days) in the tank, it can clog the carburettor and cause deterioration of the gaskets and diaphragms.
Drain out the old fuel and dispose of it properly. Once the fuel tank is empty, push the primer bulb on your tiller 7 or 8 times to clear out any fuel in the carburettor. Empty the fuel tank again. Next, mix fresh fuel in the correct ratio and fill the fuel tank. Push the primer bulb 11 or 12 times to pull the fresh fuel through the carburettor and let the tiller sit for about thirty (30) minutes. Then press the primer bulb an additional 11 to 12 times to flush out any residue. You should now be able to start your tiller using the standard starting procedure.
Note: Do not use carburetor cleaner. Doing so will void Echo engine manufacturer warranty.
