The earlier review did not establish its exact Makita model number. The documented XRU04Z example below applies only if the identification plate confirms that model: it is an older 18V LXT brushless cordless string trimmer sold as a tool-only model. It is most relevant to an existing owner or someone evaluating a secondhand unit. Value depends on its condition and the complete cost of making it usable.
Makita’s official page identifies the XRU04Z as discontinued and links its manual and parts breakdown. This is a documentation-based review, not a hands-on cutting or runtime test. Check the model plate rather than borrowing specifications from a newer Makita trimmer.
Work out what is included
“Tool only” does not establish what a used seller includes. Request an itemized list and photographs. Verify approved battery and charger combinations in the exact manual before buying components.
Ownership of another 18-volt product alone does not establish compatibility. Include any required battery, charger, guard, head and service in comparisons with complete alternatives.
Match the tool to the job
Distinguish ordinary grass edging from dense or woody growth. A string trimmer is not automatically a brush cutter. Use only approved attachments and keep protective components in place.
Comfortable reach and balance matter. If you can assess the machine safely, consider its working position with the approved battery installed. Bare-tool weight or an old “lightweight” description cannot predict every owner’s experience.
Runtime and maintenance
Battery capacity and condition, speed, vegetation and use pattern affect runtime. An “up to” claim does not promise that duration in dense growth. There is no independent runtime test behind this article, so consult the exact manufacturer’s test conditions.
The motor produces no petrol exhaust at the point of use, but that does not mean zero environmental impact. A brushless motor also does not make the whole trimmer maintenance-free: the line, head, guards and general condition still need attention.
Parts and line replacement
Makita provides a model-specific parts breakdown. Use its version information with a service dealer to identify parts rather than choosing a similar-looking head online. A diagram does not guarantee current stock or authorize a substitution.
Follow the manual for permitted line and spool replacement. Remove the battery before opening the head, inspecting damage or handling tangled vegetation. A reverse function, if documented for your version, does not make it safe to put a hand near an energized head.
Inspect before buying
Look for damage, improvised attachments, missing guards and battery or charger modifications. Ask about service history and arrange professional assessment if condition is uncertain. A motor starting is not proof that the complete machine is sound.
An existing XRU04Z may be worth maintaining when supported and suitable. For a purchase, compare condition, approved battery ownership and parts availability with current documented options. No verified evidence here supports a universal best-trimmer ranking, guaranteed lifespan or old customer-review counts.
