Question about Senco FP18 FinishPro 18 - Gauge Brad Nailer, 5/8" - 2"

1 Answer

My senco finishpro 18 won't shoot

I've adjusted the pressure on the compressor up & down, have raised & lowered the pin. There are no other visible means of adjusting the tool. When I depressed pin against wood & pull the trigger, air is released. I've tried & tried again. Occassionally it'll fire a few at startup, but that's it. I've had the gun since 2003 & have trimmed 2 houses w/it and built a few small projects. It gets a few drops of oil each time I use it (per mnfr recommendation). Any clues?

    You're right...I'd taken it to the local repair/fastener shop the day before receiving this email & an o ring replacement kit ws just the ticket. Thanks.

    Bet I haven't fired more than a dozen clips. Press the trigger and the air will fire but no about annoying.

How do you adjust nail pressure to make sure nail goes in all the way?? Bostitch model n60fn

Some devices have a control knob where the air connects. If not, you have to wait for pressure to build up. A drop or two of pneumatic air tool oil in the inlet pipe each day helps a lot. If your compressor is too small, the hose too long, or too many people on one hose, you can have a problem.

Bn125a nailer not sinking nails all the way

The depth to which a fastener is driven is controlled by the depth adjustment

knob (A) Fig. 19 below. The depth of drive is factory adjusted to a nomimal setting.

Test fire a fastener and check depth. If

a change is desired, rotate the

adjustment knob (A) Fig. 19: the

adjustment knob has detents every 1/4

turn. Rotate the knob clockwise (see

Fig. 19), to increase the depth of drive,

rotate the knob counterclockwise to

decrease the depth of drive. Test fire

another fastener and check depth.

Repeat as necessary to achieve

desired results. The amount of air pressure required will vary depending on the

size of the fastener and the material being fastened. Experiment with the air

pressure setting to determine the lowest setting that will consistently perform

the job at hand. Air pressure in excess of that required can cause premature
wear and/or damage to the tool.


Good Luck

How do I adjust the depth of the brad nail on the porter cable BN 125A brad nailer

Hello. To adjust the depth of the nail you have to increase or decrease the air pressure from the compressor. Look at the compressor and you will see a knob or dial that you can turn to increase or decrease the air pressure. Do this adjustment in small increments testing the nailer by driving nails into a scrap of the same material you will be driving the nails into on the actual job. Increasing the pressure will drive the nail deeper and decreasing the pressure will drive the nail less deep. Joe

Is there a depth adjustment for a bostitch modle mlll hardwood flooring nailer

I take it your gun isn't setting the nails? Are the nails too long?Is the pressure on 120? Is there an adj on the air line? What are you nailing into? That gun should work on 120 lbs pressure and set the nail every time, If not, one of those things is wrong, or the drive pin is broken.

When shotting the gun the nails dont go in all the way. ive tryed raising the air pressure and adjust that littlet still doesnt shoot all the way. thing on the gun but still doesnt work

you can try to use connections with bigger holes and a hose of bigger diameter, so you have more air at the gun en less pressuredrop over the hose and connections. try first to fit the gun direct to the compressor and test if it is better.

1967 case 990 tractor. My hydraulics raise but I can push them down by hand. I just purchased the tractor when I noticed water in the oil. I would like to test system pressure but I'm not sure at what...

On the right hand side of the axle on top is a cover with 2 slotted bolts holding it on. Pull this and you will see additional linkage, and a heavy cable which conrols the rockshaft. There should also be 2 valves under this cover. Pull the valves out, inspect for damage, clean them up real good and reinstall. If it continues to leak off at the rockshaft with hand pressure, Then readjust the linkages. NOTE: There are 7 adjustments to the linkage to get this to operate properly, each adjustment affects the sensitivity of the rockshaft and need to be done in sequence. Yours is a David Brown 990 tractor. Your Case dealership will have the manuals for the adjustment procedure. If after adjustment, it continues to leak off, you will need to pull the rockshaft cylinder inside the axle and have it rebuilt.

I am trying to fill a pillow for my above ground pool-can't figure out how to use my bostitch air compressor

Plug the compressor in, turn on the start switch, one gauge reads the tank pressure, the other gauge indicates the pressure in the air hose. The dial adjusts the pressure to the air hose.
