The loudest tool in the game, and the only one you cannot make
The chainsaw is the fastest wood gatherer in Rust by a distance — and the one tool you are not allowed to craft.
There is no blueprint. There is no research. You either find one in a military crate, an elite crate, a locked crate or a Chinook crate, or you take it off someone who did.
That is the whole design tension. Every other tool in the game is replaceable with metal; the chainsaw is a found object you have to keep alive, and the thing that keeps it alive is low grade fuel, which is the same resource you need for med syringes and furnaces.
The stats
| Stat | Value |
|---|---|
| Craftable | No |
| Fuel | Low Grade Fuel only |
| Fuel burn | ~1 per second while running |
| Fuel capacity | 500 |
| Damage to trees | 50 per tick |
| Damage to players | 40 per hit (a hatchet does 10) |
| Max HP | 300 |
| Inventory slots | 6 |
| Sound radius | Several map grids |
Getting it running
1. Load the fuel
Equip the chainsaw and press R to open its internal inventory slot. Drag Low Grade Fuel in.
It takes Low Grade Fuel and nothing else — crude oil has to be refined first, and if you have loaded the wrong thing the saw will not turn over.
Low grade is easy to come by: 1 animal fat + 1 cloth recycles into 3 LGF, and it is a common drop from red barrels. You can also cook animal fat in a campfire or furnace.
Carry far more than you think you need. One guide’s rule is a minimum of 50 fuel for a dedicated wood run.
2. Pull the cord
Hold the secondary fire button (right mouse button by default) to pull the starter cord.
It will not start first time, and that is not you doing it wrong — the ignition has a randomised delay as a deliberate balancing feature, so you are exposed while you stand there pulling. Most saws catch within two to four pulls, but keep holding; it often needs several seconds before the engine roars into a steady idle.
3. Do not put it away
Switching to another hotbar item stalls the engine. Every time you swap to a weapon, you have to do the whole start sequence again.
That is the single biggest time-waster on a wood run, and the reason to clear the area before you start rather than midway.
4. Holster it when you stop
The engine burns fuel the entire time it runs, whether you are cutting or not. Put the saw away the moment you finish a cluster of trees instead of leaving it idling while you sort inventory.
If it will not start
| Symptom | Cause |
|---|---|
| Clicking, no engine | Normal random ignition — hold longer |
| Nothing at all | No Low Grade Fuel loaded, or it is crude oil |
| Nothing at all | Durability at 0 — it is destroyed |
| Stalls every time you swap weapons | Working as intended; not a bug |
One guide also claims waist-deep water prevents ignition. Only a single source makes that claim, so treat it as unverified — but if your saw will not turn over on a riverbank, move to dry land before assuming it is broken.
Cutting
Hold left mouse button with the engine running and walk into the trunk.
On the red X: sources directly contradict each other. One guide says the chainsaw ignores the X minigame entirely and you should aim for the centre of the trunk mass; another guide — from the same site — says you must follow the X for a 200% gathering bonus. Nobody has settled it.
What both agree on: stay centred. Standing too far back makes the blade miss the hitbox intermittently and the wood stream stutters. Walk into the tree until the contact is continuous.
Counter the vertical recoil — the blade tries to climb the trunk, so pull your mouse down gently.
The speed claim, honestly stated
One guide claims ~14,000 wood per minute against ~1,100 for a salvaged axe. That is a 12x multiplier and should be read as a best-case ceiling, not an average.
More conservative sources say the chainsaw is 5-10x faster than an axe and that a chainsaw plus Pure Wood Tea — listed at 10 wood, 5 cloth and 1 water jug for +50% gather rate — can clear 10,000+ wood in 30 minutes.
Either way it is not close. The chainsaw is the only sensible tool for a large build.
The noise is the real cost
The chainsaw can be heard several map grids away. It is not a sound other players mistake for anything.
You are a beacon for counter-farmers and grubs. Two rules follow directly:
- Never stay in one forest more than a couple of minutes. Clear a cluster, move.
- Bring a weapon and keep your eyes moving. You cannot hear anyone approaching over your own engine.
Plan the run before you pull the cord, not during.
It is also a weapon
The chainsaw does 40 damage per hit — four times a hatchet — with a fast swing rate. Three hits kills an unarmoured player.
It also damages wood doors and barricades, which makes it a real soft-side raiding tool for wood structures.
Where it works: ambushes in dense forest, and tight base corridors where the target cannot back away.
Where it does not: anywhere with range. There is a ~1 second wind-up, no ranged attack at all, and every player within render distance hears you first.
The fear factor is genuine — the engine noise makes people miss shots — but use it as an opener, not a plan.
Keeping it alive
- Repair it at a Repair Bench with metal fragments. Keep it above ~20% durability or it can fail mid-run.
- It takes 6 inventory slots. That is a lot. Bring a backpack, and stash a box near your farming route.
- Do not leave it on the ground. A dropped chainsaw is the best thing a passing player will find all wipe.
- Do not take it to a fight you intend to lose. A found chainsaw is far harder to replace than a crafted SAR.
