How to tighten chain on black and decker cordless pole saw

if batteries are tested good check and test switch

file should be a 5/32

hi
no much that we can help you now
it look's like you need a new motor and trigger switch
or may be more cheaper to buy a new one try a different make or model this time

A properly-tensioned chainsaw chain should still be just a little loose on the chainsaw guide bar, but the chain needs to be tight enough that you can't pull the drive links out of the bar nose.

1. Remove battery from chain saw.

2. Separate main handle from chain saw

power head by pressing both release

buttons on main handle and pulling

apart. The release buttons are just in

front of the trigger.

3. Align rib on chain saw power head with

groove in power head adapter on pole.

4. Slide power head into power head

adapter until units "snap" together.

IMPORTANT: Both release

buttons on power head adapter must be

fully engaged.

5. Align rib on handle adapter on pole

with groove in main handle.

6. Slide main handle into handle adapter

until units "snap" together.

IMPORTANT: Both release buttons

on main handle must be fully

engaged.

7. Slide battery onto main handle until

release buttons "snap" together.

Be sure the battery is charged.

To extend the pole:

1. Loosen the clamping

lever. Pole will slide

freely.

2. Pull inner pole section out to desired

length of extension.

3. To lock pole in position, tighten clamping

It sounds as though you have bent drive links? I would probably replace the chain. Burrs we can help, see Chain Repair here:

You do not mention the model number.
Honestly, I had never used a pole saw, but I needed to cut down a lot of tree branches and Black+Decke worked wonderfully. With it being cordless I could easily walk around my entire yard without worrying about it. The chain does loosen after cutting through several limbs, but it's super easy to tighten back. It's easy to assemble.

It's depend on parts. chack the link https://polesawusa.wixsite.com/pole-saw

You need to know the size pitch and brand of the chain. See if it has a name on it anywhere. It may have a pitch # stamped on the side. My remington uses a Oregon chain.

Check the chains at walmart and see if they look the same. You may find a cross ref on the package that will give you another part#

Another option is to replace the bar and chain with a new Oregon Replacement Bar & Chain Combo kit.

See this site for examples.
