It operates a diaphram every time the piston moves up or down. Has a check valve to keep the oil flowing in the right direction.
Lots of people talk poo about them but they are probably the most reliable oiler ever invented.
I've only ever seen one that was bad and the old guy ran used motor oil for bar oil from the time the saw was new. (12-15 years)
I wish I could buy a new lightweight saw with the impulse automatic oiler and manual over-ride still today. I'd be on that like a settin' hen on a housecat!!!
When you pick up a 3400/3700/4000 for the first time each day you can hit the manual oiler as you set the throttle lock. Pull the choke, hit the ignition and crank 'er up. You know the chain has proper lubrication from the first time it fires.
The gear drive oilers, especially when its cold, may not get oil to the chain for 30 seconds or more and if it is REALLY cold you can strip the gears in them trying to pump super thick oil and not get any at all.
