About This MTD String Trimmer

This trimmer is part of MTD’s RM series of two cycle gas trimmers, sold with several closely related specification codes that share the same basic small displacement engine and bump feed head design across different production runs. Because MTD revised minor components across these specification variants, confirming the complete model and specification code stamped on the engine housing helps ensure a carburetor kit or air filter is sized correctly for this specific trimmer rather than a similar sibling from the same RM series. Like most two cycle handheld outdoor tools, this trimmer requires fuel premixed with two cycle oil rather than straight gasoline, and running the wrong fuel mixture even briefly can cause lasting engine damage. Storing the trimmer indoors or under cover between uses protects electrical connections and fuel system components alike from the moisture that accelerates corrosion and wear over time. Wiping debris from the shaft and head after each use, before it has a chance to harden or dry in place, keeps moving parts working smoothly for longer between services. Checking that fasteners along the shaft and head remain properly tightened before each use helps prevent excess vibration that can accelerate wear on internal components. Reviewing the owner’s manual for this specific model before attempting any repair helps confirm torque specs and part orientations that are easy to get wrong from memory alone. Inspecting the cutting attachment for damage before each use catches a cracked or unbalanced head before it causes excess vibration or uneven cutting. Keeping the guard shield securely attached during use protects the operator from thrown debris and is worth confirming after any disassembly for repair. Letting the trimmer cool fully before storing it in an enclosed space reduces the fire risk that comes from packing away a warm engine or a freshly charged battery pack. Rotating trimmer line stock periodically rather than leaving a single spool loaded for a long stretch helps prevent the line from becoming brittle before it is ever used.

Most Replaced Parts on the RM2560

Carburetor and Hard Starting Issues on the RM2560

A trimmer that floods, stalls right after starting, or will not start at all after sitting over winter usually has a gummed up carburetor from stale, ethanol blended fuel. Confirm the fuel mix is fresh and correctly ratioed and the spark plug fires before disassembling the carburetor.

Spark Plug and Ignition Problems on the RM2560

When the engine will not fire despite fresh fuel, remove the spark plug and check its condition before assuming the ignition module has failed. A plug fouled by a rich fuel mixture is a far more common cause of no spark than an actual ignition failure on this size of engine.

Air Filter and Airflow Issues on the RM2560

A clogged foam air filter forces the engine to run rich, causing rough idle and difficulty restarting once warm. Inspect and clean or replace the filter before assuming a carburetor problem, since a dirty filter is a more common cause of poor running.

RM2560 Parts FAQ

Does this trimmer need mixed fuel?

Yes, this is a two cycle engine that requires fuel mixed with two cycle oil at the ratio listed in the owner’s manual rather than straight gasoline.

Why won’t the trimmer start after winter storage?

Stale, ethanol varnished fuel in the carburetor is the most common cause. Check the spark plug and air filter first, then inspect the carburetor if it still will not fire.

Do parts from other RM series trimmers fit this one?

Often similar, but always confirm the complete model and specification code stamped on the engine housing before ordering, since MTD revised minor components across production runs.

How should I store the trimmer between seasons?

Drain the fuel tank or run the engine dry before long term storage to prevent carburetor varnish from building up.
