Sun Joe SWJ803E Electric Pole Saw | 10-Inch Bar & Auto Oiler
We built the SWJ803E for homeowners who need serious overhead reach without the weight and fumes of a gas pole saw. This corded electric model extends to 8.7 feet, putting you 15 feet above ground when you factor in your own height and arm extension—enough to tackle most backyard branches while keeping both feet planted.
The 10-inch Oregon bar and chain system cuts through limbs up to 9.5 inches thick, and the 8-amp motor delivers consistent power as long as you have an extension cord. Our automatic chain oiler keeps the bar lubricated during every cut, so you’re never stopping mid-job to manually drip oil. The aluminum telescoping pole is lighter than steel but strong enough for all-day pruning sessions, and the inline motor design balances the weight better than rear-handle chainsaws mounted on a stick.
What’s included with the SWJ803E
Bar, Chain & Cutting Performance
The sun joe swj803e uses a genuine Oregon 10-inch bar paired with a low-kickback safety chain—the same components you’d find on professional-grade equipment. We chose this combination because Oregon’s heat-treated steel holds an edge longer than generic chains, which means fewer sharpening sessions between jobs.
The 8-amp motor spins the chain fast enough to slice through green oak and maple without bogging down, provided you let the saw do the work instead of forcing it. You’ll get the cleanest cuts when you approach branches at a slight angle and let the chain’s teeth pull themselves through the wood. For limbs thicker than 7 inches, make an undercut first to prevent bark tearing as the branch drops.
Reach, Extension & Overhead Clearance
The telescoping pole adjusts from 5.9 feet fully collapsed to 8.7 feet at maximum extension, locking in place with a twist-collar mechanism. Add your own height and arm reach, and most users can access branches 14 to 16 feet off the ground without a ladder.
We built the pole from anodized aluminum to keep the entire saw under 10 pounds—light enough to hold overhead for several minutes at a time without arm fatigue. The inline motor design puts the weight directly behind the bar instead of hanging off to one side, which reduces wrist torque when you’re cutting at awkward angles above your head.
Automatic Oiler & Chain Maintenance
The SWJ803E includes an automatic lubrication system that drips bar oil onto the chain while the motor runs. The translucent reservoir on the motor housing holds 2.7 ounces of oil, enough for about 20 minutes of continuous cutting before you need to refill.
Use standard bar and chain oil—the same stuff sold for gas chainsaws—and check the level before each job. The oil keeps the chain from overheating and prevents premature wear on the bar’s guide groove. You’ll know the oiler is working when you see a fine mist of oil spray off the bar tip during cuts.

Questions About the SWJ803E Pole Saw
Use a 14-gauge outdoor extension cord for runs up to 50 feet, or a 12-gauge cord if you’re stretching 100 feet from your outlet. The saw draws 8 amps, so make sure your cord is rated for at least 12 amps to prevent voltage drop and overheating.
We recommend locking the cord into the strain-relief hook on the motor housing to prevent it from unplugging during cuts. Always plug the saw into a GFCI-protected outlet when working outdoors.
The SWJ803E is designed for overhead pruning, not ground-level logging. The pole length and inline motor design make it awkward to use horizontally for cutting firewood or felled trunks.
If you need to buck logs, we recommend a standard chainsaw with a rear handle and longer bar. The SWJ803E excels at reaching branches 8 to 15 feet off the ground while you stay safely planted on the lawn.
The 2.7-ounce oil reservoir typically lasts about 20 minutes of continuous cutting. Check the translucent window on the motor housing before each job, and top it off if the level is below halfway.
Use standard bar and chain oil—the same type sold for gas chainsaws. You’ll know the oiler is working when you see a fine mist spraying off the bar tip during cuts. If the chain starts smoking or the bar feels hot, stop immediately and check the oil level.
The 10-inch bar can handle branches up to 9.5 inches in diameter, though cutting performance is best on limbs 6 inches and under. For anything over 7 inches, make an undercut on the bottom side first to prevent the bark from tearing as the branch falls.
Let the saw do the work—forcing the bar through thick wood will bog down the motor and wear the chain faster. If you’re regularly cutting branches thicker than 8 inches, consider upgrading to our <a href=’/pole-saws-chainsaws/sun-joe-swj806e/’>multi-angle pole saw</a> with adjustable head positioning for better leverage on heavy limbs.
Yes, the Oregon chain ships factory-sharpened and ready to cut. You’ll get the best performance for the first several hours of use, then you’ll need to sharpen it as the teeth dull from contact with wood.
We recommend sharpening after every 2 to 3 hours of cutting, or immediately if you notice the saw producing sawdust instead of wood chips. You can use a round file and guide, or bring the chain to a hardware store for professional sharpening.
No—always turn off the motor and unplug the saw before adjusting the telescoping pole. The twist-lock collar needs to be loosened to change the length, and doing this while the chain is spinning creates a serious safety hazard.
Set your desired pole length before plugging in, and make sure the collar is tightened fully before you start cutting. The pole locks securely at any point between 5.9 and 8.7 feet.
The SWJ803E motor is calibrated for a 10-inch bar, and installing a longer bar will overload the 8-amp motor and void your warranty. Stick with the original Oregon 10-inch replacement bar and chain designed for this model.
