Xinabo builds the XJ.204 as the compact end of its cordless chainsaw line: a 16V DC brushless tool with a 4-inch guide bar, a 100 mm maximum cutting diameter and an automatic oiling system that lubricates the chain during the cut instead of relying on a manual oil can. It belongs to our Cordless Power Tools group, which we produce alongside the intelligent pipe threading equipment and pipe fabrication machinery that made our name in fire protection and construction work.
Where a 100 mm cut covers the job — branch trimming, fruit-tree shaping, small timber, model and furniture repair, campfire wood — the XJ.204 replaces a hand saw with a clean, fast cut in a body light enough to run one-handed. The XJ.204 16V 4" Brushless Electric Chainsaw — Compact & Lightweight, Auto-Oiling System manufacturer page carries the full parameter set for this model.
Where the XJ.204 Sits in Our Cordless Chainsaw Range
We supply two bar lengths in this family, and the choice is decided by the largest diameter the operator has to pass through the cut. The XJ.204 is the single-hand compact unit for trimming and light woodworking; the XJ.206 16V 6" Brushless Electric Chainsaw — 150mm Max Cutting Diameter, Two-Hand Grip takes the same 16V platform to a 6-inch bar and a two-hand grip for heavier limbs and larger section timber.
- Home and estate gardening: branch trimming, fruit-tree shaping and yard wood cutting where the cut stays under 100 mm.
- Light woodworking: small timber, model making and furniture repair that need a short, controllable bar rather than a bench saw.
- Outdoor and camp use: campfire wood and outdoor equipment work where mains power is not available.
- Site housekeeping: cutting down packaging timber, pallets and offcuts where a compact cordless tool is easier to carry than a full-size saw.
Specifications and What Each One Means on the Job

Practical meaning |
| Rated voltage |
16V DC |
Cordless operation on the 16V battery platform; no mains lead in the tree or on the bench. |
| Motor type |
Brushless |
No carbon brushes to wear or replace and no brush dust; energy goes to the chain rather than to friction. |
| Guide bar size |
4" |
Short bar keeps the nose visible and the tool balanced for one-handed trimming. |
| Chain speed |
450/min |
Fast chain travel for clean cuts in green branches and dry timber within the bar's capacity. |
| Max cutting diameter |
100 mm |
Defines the working limit: limbs, board offcuts and small logs up to 100 mm across. |
| Lubrication |
Automatic oiling |
Oil reaches the bar and chain during cutting, so the operator does not stop to oil between cuts. |
| Safety features |
Safety lock, anti-kickback |
The safety lock stops the chain on accidental contact; anti-kickback control limits reaction at the bar nose. |
| Standard accessories |
Guide bar, chain, charger, lubricating oil, carry bag |
Ships as a working kit; bar and chain are fitted and tensioned at first assembly. |
Brushless Motor and the 16V Platform
A brushless motor removes the two consumable parts that decide the working life of a small chainsaw: the brushes and the commutator they ride on. On a 16V tool that matters more than on a large machine, because the pack has limited energy and every loss shows up as shorter runtime and slower chain recovery under load.
- No brush dust inside the motor housing, so the tool stays cleaner in sawdust-heavy work.
- Electronic commutation keeps torque available as the chain meets a knot or a denser section of timber.
- Fewer wearing parts means a maintenance routine built around the bar, chain and oil rather than motor service.
Automatic Oiling and Chain Life
Chain wear is decided by lubrication as much as by cutting technique. The XJ.204 feeds oil to the bar and chain automatically while the motor runs, which keeps the rivets and the bar groove supplied during long trimming sessions and reduces the heat that stretches a chain and dulls cutters.
- Fill the reservoir with the lubricating oil supplied in the kit before the first cut and check the level at each refill of the session.
- Keep the oil feed hole and bar groove clear of sawdust; a blocked channel starves the chain however full the tank is.
- Re-tension the chain after the first few cuts on a new bar, then check tension before each use.
Safety Systems, Grip and Handling
The safety lock cuts the chain immediately on accidental contact, and the anti-kickback arrangement limits the reaction that occurs when the top of the bar nose meets wood. The anti-slip handle keeps the tool steady in a gloved hand, which is the practical requirement for pruning work carried out at height or on uneven ground.
The body is balanced for one-handed use on light trimming cuts. For heavier sections, sustained cutting or work at full bar depth, both hands belong on the tool and the workpiece should be supported so the bar cannot pinch.
Battery, Charger and Delivery Scope
Each XJ.204 ships with the guide bar, chain, charger, lubricating oil and a portable carry bag, so the kit can be issued to a crew or a retail shelf without extra assembly items. Battery quantity and pack format are fixed at order stage, together with the plug type and input voltage of the charger for the destination market.
For wood cutting beyond the 4-inch bar, our XJ.853 21V Lithium-Ion High-Magnetic Brushless Circular Saw — 140mm Blade with Laser Guide Line covers straight cuts in board and sheet, and the 6-inch XJ.206 covers larger limbs.
Quality Control and Acceptance Checks
Hangzhou Xinabo Intelligent Electromechanical Technology Co., Ltd was established in 2010 and operates a 10,000 m² factory in Linpu, Xiaoshan, Hangzhou, Zhejiang, China, with more than 100 employees, a 99.9% finished product rate and 30-plus patents to its name, together with the National High-Tech Enterprise title. Our certificate file includes Machinery Directive and Electromagnetic Compatibility Directive attestation of conformity for the equipment we build.
Before a chainsaw batch is packed, we run the checks that decide whether the tool works on the first pull of the trigger:
- Bar and chain fit, chain tension and free rotation of the chain by hand.
- Oil delivery at the bar during a short run, with no leakage when the tool is stored upright.
- Safety lock and anti-kickback function, plus trigger and motor response.
- Charger output and pack contact, accessory count against the packing list, and carry-bag contents.
Installation, First Run and Maintenance
First assembly is a bench task: mount the bar on the stud, loop the chain with cutters facing forward on the top run, engage the sprocket, then tension until the chain sits against the bar and can still be pulled around by hand. Fill the oil reservoir, check that oil reaches the bar, and run the tool briefly before the first cut.
- Daily: oil level, chain tension, bar groove and oil hole, visible damage to cutters or drive links.
- Weekly or after heavy use: flip the bar, clean the sprocket cover, check the charger and pack contacts.
- Wear parts: chain, guide bar, lubricating oil and charger are the items that keep the tool in service; we hold spares for the products we build.
- Storage: drain or check oil before long storage, and keep the tool in the carry bag away from damp.
Information We Use to Configure Your Solution
- Wood type and the largest diameter to be cut, so the 4-inch XJ.204 or the 6-inch XJ.206 is specified correctly.
- Cuts per day and how the tool is carried — belt, bag or vehicle — to set the battery quantity per kit.
- Destination market, charger plug type and input voltage, and the language required on labels and manuals.
- Order quantity, packaging format, branding requirements and whether a spare chain and bar should be included.
- Spare-parts and after-sales plan, including who handles warranty exchange in the destination market.
Frequently Asked Questions
What is the maximum cutting diameter of the XJ.204?
100 mm with the 4-inch guide bar. Anything larger belongs on the 6-inch XJ.206, which reaches 150 mm and is built with a two-hand grip for that load.
Does the operator have to oil the chain by hand?
No. The automatic oiling system feeds oil to the bar and chain while the motor runs. The operator keeps the reservoir filled with the lubricating oil supplied in the kit and keeps the oil hole and bar groove clean.
Can the XJ.204 be used with one hand?
Yes. The compact body and 4-inch bar are balanced for one-handed trimming and pruning. For heavier cuts, full bar depth or work at height, use both hands and support the workpiece so the bar cannot pinch.
What is included with each chainsaw?
Guide bar, chain, charger, lubricating oil and a portable carry bag. Battery quantity and pack format, charger plug type and input voltage are confirmed on the order so the kit matches the destination market.
How do we place a first order or request a sample?
Send the cutting application, the largest diameter, expected cuts per day, destination market and required quantity.
