Makita UC3551A specifications and status
The table uses the combined UC3551A/UC4051A instruction manual unless a different Makita document is named. The UC3551A is the 14-inch model in that manual; values for its 16-inch sibling should not be copied onto this page or onto a replacement-parts order.
| Item | UC3551A documentation |
|---|---|
| Power type | Corded electric |
| Standard guide bar | 350 mm (14 in); manual part number 165201-8 |
| Cutting length | 320 mm (12 5/8 in) |
| Chain details in manual | 91PX; 3/8 in pitch; 52 drive links |
| Maximum chain speed | 14.5 m/s (2,900 ft/min) |
| Net weight | 5.5 kg (12.1 lb), as stated in the instruction manual |
The bar's 350 mm length is not the same as its 320 mm cutting length: the manual reports both values for the UC3551A. Neither number is a safe maximum log diameter or a promise of cut capacity in every species and setup. A log's support, condition, chain sharpness and operator control all affect the work; use the saw only for tasks allowed by its manual and your training.
The manual's maximum chain speed is a specification, not an independent cutting-speed test. The manual lists a net weight of 5.5 kg (12.1 lb), while Makita's older flyer labels 12.1 lb as weight without the bar and chain. Because the published documents describe the measurement basis differently, compare weight figures only when the fitted bar, chain and measurement method are stated.
Makita's US product page marks the UC3551A as discontinued. It still links to a manual and parts breakdown, which helps identify the original configuration, but a documentation link is not proof that a spare part is currently available. Check stock and the exact part reference with the seller or an authorized service source before planning a repair.
Which chain fits the UC3551A?
There is a consequential discrepancy in Makita's own documents, so a generic “14-inch chain” answer is not reliable. The instruction manual identifies chain type 91PX, 3/8-inch pitch and 52 drive links. Makita's older UC3551A flyer lists the original chain part 196207-5 as 3/8 inch with a .050-inch gauge. A current Makita E-00228 accessory page describes a 14-inch, 52-link 90PX chain with 3/8-inch low-profile pitch and .043-inch gauge and says it is for the UC3551A; Makita's newer accessory catalog also maps that chain to the model.
Pitch describes chain size; gauge is the thickness of each drive link where it sits in the guide-bar groove. The chain gauge must match the bar groove, while pitch must also suit the saw's drive sprocket. Drive-link count determines the chain length needed for the particular bar. That is why matching only “14 inch” or “52 links” cannot resolve the Makita document discrepancy.
Those references do not establish that every UC3551A still has the same guide bar. A bar may have been replaced during the saw's service life, and a chain's pitch, gauge and drive-link count must match that bar together. The safest conclusion from the documents is that Makita lists E-00228 as a compatible accessory, while older documents describe a different original chain specification. Confirm the marking and part number on the installed bar before ordering; if the marking is missing or unreadable, ask Makita service or a qualified chainsaw shop to identify the correct combination.
Compatibility check at a glance
- Manual: 91PX, 3/8-inch pitch, 52 drive links.
- Older flyer: original chain part 196207-5, 3/8-inch pitch, .050-inch gauge.
- Current Makita accessory listing: E-00228, 90PX, 3/8-inch low-profile pitch, .043-inch gauge, 52 drive links; listed for UC3551A.
- Before fitting any chain, match its specifications to the actual installed guide bar and the saw's instructions.
How to verify a replacement bar or chain
Use this sequence to reduce the chance of buying a chain that fits the nominal bar length but not the saw. It is an identification checklist, not an installation procedure; use the manual for removal, adjustment, tensioning and safety steps.
- Read the saw model plate. Confirm that the body is marked UC3551A. The similar UC4051A uses a different standard bar and chain length.
- Read the bar markings. Look for the manufacturer's part number and the pitch and gauge stamped on the guide bar. Do not infer these measurements from the bar length or saw model alone.
- Match all chain dimensions. Confirm pitch, gauge and drive-link count against the installed bar. “14 inch” only describes nominal bar length; it does not identify those other dimensions.
- Compare the part reference. Makita's current E-00228 listing and older part references describe different specifications. If the saw has an older or replacement bar, verify the relevant bar-and-chain pairing first.
- Check the documentation for the exact revision. Makita notes that specifications can vary by country and change over time. Use the matching manual and parts breakdown where possible, and ask a service professional when the installed configuration cannot be identified.
Do not use a chain that merely slides over the bar or appears to have the right number of cutters. An incorrect pitch or gauge can prevent proper seating and lubrication; a wrong drive-link count cannot maintain the specified fit. If the bar, sprocket or chain has been changed, the replacement must suit the full cutting system, not just the UC3551A name.
UC3551A vs UC4051A
The UC4051A is a related corded model, not a longer-bar version whose parts can automatically be swapped. The manual gives it a 400 mm (16-inch) standard bar, 355 mm cutting length, 56 drive links and 5.6 kg net weight. The UC3551A uses a 350 mm (14-inch) standard bar, 320 mm cutting length, 52 drive links and 5.5 kg net weight. Both models appear in the same manual, which is one reason listings and parts pages can mix the names.
When comparing a used saw or searching parts catalogs, check the complete model code before relying on a family description such as “Makita electric chainsaw.” A 16-inch UC4051A chain listing is not a substitute for a UC3551A chain. The manual's model-specific table and the part number on the fitted bar are the most useful references.
What owners should check on a discontinued saw
A discontinued tool can still be useful to an existing owner, but an old listing is not enough to confirm that a saw is ready for service. Check the condition of the power cord, plug, switch, chain brake, guide bar and chain; confirm that the oiling system and chain tensioner work as the manual describes; and make sure the correct guard and other safety parts are present. Stop using the saw if an electrical part is damaged or a safety control does not work, and have it assessed by a qualified service provider.
Before buying a second-hand UC3551A, ask the seller for clear photographs of the model plate, bar markings, plug and saw body. Confirm whether the bar and chain are original or replacements, whether the manual and bar cover are included, and whether the saw can be inspected safely. Do not treat a claim that it “runs” as evidence that its brake, lubrication, cord and chain fit have been checked.
If you are deciding whether to repair or replace one, compare the diagnosis and parts cost with the needs of the job. The UC3551A is a corded 14-inch saw; it requires suitable outdoor power access and cord management throughout the cut. If the work site cannot provide that safely, the older saw's specifications will not make it a suitable choice. For another corded model documented for the US market, see the Oregon CS1500 guide; it covers a different saw and is not a direct test comparison.
Cord, moisture and chainsaw safety
Use the UC3551A instruction manual for the required supply, extension-cord size and length, chain adjustment, lubrication and operating procedure. Do not guess the cord specification from another Makita model or generic listing. Before each use, inspect the cord and plug for cuts, crushed sections, exposed conductors or damaged pins. OSHA warns that damaged flexible cords can cause shock, burns or fire, and that connectors exposed to water can create a shock path.
Makita's manual warns against operating the saw in rain or wet conditions. Route an approved outdoor cord so it remains visible and away from the bar, chain, feet and likely cut path; keep connections out of standing water and disconnect power before inspection or maintenance as the manual directs. Keep both hands on the handles, secure the workpiece, maintain stable footing and wear the protective equipment specified by the manufacturer. Do not use a chainsaw for overhead cutting or work beyond your training; seek qualified instruction for felling or cutting tensioned wood.
