Trimmers FAQ
What is the recommended procedure for preparing my ZOMAX trimmer for long-term storage (over 30 days)?
Only if you plan to “mothball” your lawn trimmer, brush cutter or chainsaw for a longer period – say during the winter months – should you pay a little more attention to the topic of “care.” This will ensure that your equipment, when required, will be ready for action.
1. The fuel stored for a long time will cause the engine can not always start, so when storing the machine for a long time, pour the fuel in the fuel tank, then start the engine until the residual fuel in the carburetor is consumed, and the machine automatically shut off.
2.Clean the surface of the paper filter element, if it is seriously damaged, please replace it in time: Wash the air filter mesh with soapy water,2 then dry it thoroughly and put it back.
3. Remove the spark plug, inject a few drops of oil into the combustion chamber, pull the starter so that the piston stops at the upper stop position and put back the spark plug.
4. Remove the blade and rub a little oil on both sides.
5. Clean each part and replace the damaged ones in time.
6. Take necessary measures against dust and rust, and store the machine in a ventilated and dry room.
My ZOMAX trimmer will start and run at idle but will not run at full throttle. What's wrong?
There are several things you can check. First, make sure that you are using fresh fuel mix (never store or use fuel mix older than 60 days in can or fuel tank). Second, clean spark arrester screen in the muffler. Third, replace fuel filter in fuel tank. Fourth, clean or replace air filter. If none of these work please contact us or take the machine to your local authorized servicing ZOMAX Dealer for evaluation.
My trimmer line won't advance or breaks off at the head. What's wrong?
This can occur when the trimmer head is not bumped often enough and it becomes too short for centrifugal force to advance the line. When advancing trimmer line, be sure to do so at wide open throttle.
My ZOMAX trimmer won't start. What can I do?
Always read your product instruction manual. When starting your ZOMAX trimmer make sure that you have fresh fuel mix of 25:1/40:1 octane or higher and never pull the starter more than 3 times in the choke position. If you have pulled more than that, more than likely it is flooded. Indications of flooding are the strong smell of gasoline or gasoline coming from the muffler. The best thing to do at this point is allow the trimmer to rest for 20 to 30 minutes then attempt starting again. Do not choke the unit, but leave the throttle lock on. If it still will not start, we recommend contacting us or taking it to your local ZOMAX Dealer for evaluation.

Can I put an attachment on my ZOMAX curved shaft trimmer?
Curved shaft trimmers are not authorized for any attachments.
Does ZOMAX make a straight shaft trimmer that turns clockwise?
ZOMAX does not produce a straight shaft trimmer that turns clockwise. Only our curved shaft trimmers do.
What is the difference between curved and straight shaft trimmers?
Curved shaft trimmers are designed for light duty trimming while straight shaft trimmers are designed for more aggressive trimming and brush cutting. Most models are available in loop handle or bike handle versions.
How do I know if my ZOMAX trimmer will accept other cutting heads?
Please contact your authorized ZOMAX Dealer for special accessories that may be available for your trimmer.
Where do I find my serial number?
On homeowner trimmers, it is located on the bar code label on the fan casing. On professional units and brush cutters it is on the bar code label and stamped in the top of the cylinder or main crank case. All current serial numbers will be nine digits long and begin with the numbers 1, 2, 5, 8, or 9.
Can I adjust my own carburetor?
The carburetor comes from the factory with a standard setting. This setting provides an optimum fuel-air mixture under most operating conditions. With most carburetors, it is only possible to adjust the engine idle speed within fine limits. Quite often adjusting the carburetor will not solve acceleration issues. To find the correct setting for your machine, please refer to your instruction manual. If you do not have a copy of your instruction manual, please go to our product manual web page where you can download a PDF version.
How often should I have my ZOMAX trimmer tuned up?
Please refer to your instruction manual under the maintenance and repairs heading.
How can I tell when my ZOMAX trimmer was made?
ZOMAX does not incorporate production dates into our serial numbers.
What is the correct spark plug gap for my ZOMAX trimmer, chainsaw or blower?
The correct gap setting is 0.020".
