When my pole saw is extended it is shaking really bad runs fine when it's not what could this be ?

Want to saw up high, but think it's dangerous to saw on a ladder? Good thinking. So how can you get your saw to reach those high branches while keeping your feet planted on the ground?

Take a lightweight chainsaw, add a stick, and you get a pole saw.
TYPE There are three types of pole saw. You can choose any one of them based on your requirements.
CORDLESS POLE SAW Cordless pole saws are said to be the handiest pole saw as it removes the hassle of carrying wires and cords during pruning. It operates through a rechargeable battery. But, due to its battery pack, its operation time is very specific. If you want to extend the time for heavy duties, you can use extra battery packs.
One of the best advantages of cordless pole saw is its need for low-maintenance. You would hardly need to maintain its well-being.
GAS POWERED POLE SAW Gas powered pole saws are mostly chosen by the professionals for its heavy-duty bars and chains and have the power to cut huge and large branches with ease. This pole saw can be extended up to 9 inches so you might distinguish its expertise in trimming high rise trees. It is good for regular use. It is heavier than the electric one and noisy also. Despite being heavy, you would not face any problem working with it as the pole saw is easy to balance.
ELECTRIC POLE SAW Electric pole saws are preferred for small branches trimming as it has blades of 6"-10". It weighs about 10 pounds that means you can carry the saw effortlessly. It does not require high maintenance as well. Plug the long extension cord before you start, aim at the branches and begin pruning with this electric pole saw.

Tried chain saw. Working on limbs about 12 ft above ground.
First limb about 3 inches diameter, Oak. Worked fine.
Second limb same size. Cutter slip off branch could not stop the saw from hitting ground. Broke case where it attaches to pole.
No parts, and no way to repair it as company had no idea what kind of cement/glue I could use. So one branch cost me $120.00.

Like Robert my saw hit the ground and busted in the same spot (this will happen to you sooner or later) and you can not get repair parts, its now a door stop.
Pros: Easy To Use, Light Weight
Cons: Can Not Get Repair Parts
I am guessing you mean the entire cutting end of the saw too, I would get a new one either same model so you have a spare pole or find a another brand that definatly sells spare parts.
Ive never used a electric polesaw but have done alot of work with with longer petrol and shorter hydrolic polesaws, even top of the range they can be broken easily always keep the chain sharp, cut one branch at a time or small clumps on a hedge.
Commonly they get dropped cause they get really heavy extended a shoulder belt helps alot as do coffee breaks.
Or they get jammed in the branch being cut which can be really dangerous with a half cut branch, be ready to run.
Also never use from a ladder

lots of luck there, if you have tried Remington, with no luck may i suggest a automotive hose clamp and a piece of inter tube.

I bought this chain without first examining the "count" of my old chain. I found this new chain had 39 drive-links while my OLD chain had 40 links. My 10" Remington saw had enough chain-tensioning adjustment to compensate for that missing link and this new 39-link chain runs fine... cuts very well. Happy.

Okay here is the Fix for the Remington Pole for the remington saw. Lowes has a plumbing part that will work as I just purchased it 12/2010 The part is by GENOA and its a 3/4" pvc Union and the threads match. Its Lowes part 98996 and its < $6.00

Problem is most likely in the trigger switch on pole. Bypass switch and test bu plugging lamp into power cord coming from pole

The chain has to be tensioned when replaced. You lift the chain away from the bar about halfway and the tangs that run in the bar should just almost come out of the groove. There is a screw that extends the bar near where it attaches near the sprocket. adjust that with the bar mounting nuts not quite tight till the chain is tensioned correctely.
