On most trumpets, you simply pull it out.
you can try to oil it with slide grease or take it to instrument store.
Take it to a gunsmith
Your slide on your carberator is not allowing the carb to open all the way. You need to take it off and trim the slide about 1/4 inch
First, remember to hold down the valve before moving the slide. If you can get the slide off (by pulling gently), then I would suggest wiping off the slide and applying some slide grease. Note that this is not the same as valve oil. If you don't have slide grease, try asking a trombone player if you can borrow a little bit.If you still cannot get the slide to go all the way back in, take it to a repair shop. Never try to force one piece of an instrument into another - you risk doing permanent damage.
Look for master link then take off master link clip then slide master link off
Hold the power button until you see the power off slide, and then turn it off. This process may take twice as long to get to the power off slide and for it to totally turn off.
take it off the ring, slide off the black plastic cover on your key
take tire off! remove the slide pins on caliper,should be Allen wrench heads on bolts. then slide off of rotor!!
take out top slide pin using Allen wrench push and pry top of calliper down , i mean way forward streching hose slightly and take caliper and slide it off the bottom slide pin .
Should be "peel off" type Remove wheels Remove caliper mouting bolts Slide caliper off rotor Rotor should slide off hub
take wheels off, remove brake calipers. rotors slide right off.
You have to take out the bolts on the hub and then the big lock nut on the axle then it should slide off.
