Freight Orders

Freight deliveries require a delivery time be scheduled and someone must be present at the time of delivery to inspect and sign for the merchandise. A representative from the freight carrier will call the phone number entered at checkout to schedule the delivery.

Liftgate Service

For freight deliveries, you have the option of adding a liftgate to your delivery. A liftgate is the device that lowers a product from the truck to ground level.

CPO recommends adding liftgate service for freight deliveries exceeding 100 lbs if you do not have a loading dock or fork lift at the delivery address. Additional charges may apply. The liftgate option will be presented during the checkout process.

Please note that liftgate service only ensures the product is removed from the truck. We recommend you have the additional help of two to four people to move the product to its desired location because drivers are not required to assist.

Requesting liftgate service after ordering may result in additional charges and delays.

Easy To Use
New Jet JJP-12HH a pleasure to use
Machine was set to tolerance from the factory. Very easy to use and change set ups. Takes about 20 seconds to go from jointing to planeing or back. Wood is very smooth from planer. A really great design. High five to Jet on this one.

Get's it done right out of the box
Doesn't take up a lot of space and very easy to use. I thought it would be difficult to switch between tasks on a combination machine. I can switch from jointing to planing in about 20 seconds.

One of best investment I've made
I do segmented turning. So proper sizing of the wood I use is critical. The Jet JJP-12HH leaves a smooth finish, it virtually eliminates tear-out. Even in exotic and highly figured wood. The helical head makes a world of difference. It is also a lot quieter than a straight blade jointer or planer. Change over is very quick and easy, takes about 15 seconds. Dust collection also works very well. I think every woodworker should have one of these!

I purchased a JJP-12HH from CPO outlet.
It arrived earlier than expected, but it had a little damage from shipping. I called CPO, they were very helpful giving me the information needed to call Jett for replacement parts. I called Jett and they were very politree and responsive to my request to replace the damaged parts, the parts were in stock and I received them in a day or two. I have only had the opportunity to run a few boards through the machine, so far I am happy with the choice I made to purchase a Jett. I will update my review after a few more hours of operation.

Had my first opportunity to use my new JJP-12HH 12" planer/jointer and the boards are coming out concave from end to end on face joints? I would expect some of this on longer boards but I was flattening boards only 48" long. Please advise as to solution. David Turner, Raleigh, NC.

Please contact the manufacturer direct @ 1-800-274-6848 for technical assistance.
Does this item come shipped in multiple parts or fully assembled? I need to get this into a basement and can't see moving it fully assembled.

BEST ANSWER: This item will ship in two containers, so there is some assembly required.
