Hansa C7 Questions & Answers (page 2 of 2)

4.8kw

This question is best referred to Hansa.

I have not had to do this yet, however I do know you need to remove/move the engine. This may seem like a major task, but it actually looks pretty easy. Once I get to that I intend on making a video and putting it up on YouTube.

I've found it easy to do with my machine. It's an older design which has the clutch lever (I believe the newer ones use a jack screw). Remove the two bolts holding the belt guard. Remove the four bolts holding the engine to the engine mount and move the engine out of the way. Then the belts can be pulled off the bottom pulley. It's the reverse procedure to put belts back on.
Tips: Marking the position of the engine on the mount before undoing anything so you can get it back to the same position. Once everything is back together, use a paint pen to mark the orientation of the nut/bolt head in relation to what it's securing so it's easy to see if they're coming loose - I've never had this problem, but I see it as cheap insurance (just like grease, oil and filters).

Xclnt - thank u v much - not a 5 min job but do- able for someone like me - thanks agaon

Hi Tim, I would have no problem feeding all of that and more into my Hansa C7. As long as it is no wider than the chute (about 70mm) then shove it in and chomp it up.

If the material is too stringy I find it can clog the machine, however if you simply feed it slower and less in each bundle then it shouldn't be an issue.

Good Luck :)

Hi Michael K. Firstly, can I say that after 8 months of using the Hansa C7 I'm still very impressed in all respects with it. I have mulched leaves in it but it needs woody material to help feed the leaves through. Remember this machine is a 'chipper' mulcher not a 'shredder'. The mulch it produces is course not fine. Sometimes when mulching gum tree branches some of the gum leaves come out in one piece but the branch and twigs get mulched. If you are wanting fine mulch for your garden you might need to keep looking for a different machine. If you are after a chipper that starts easy and eats through large branches (up to 60mm) and produces course garden mulch then you won't be disappointed with the C7. I hope this helps.

As far as I'm concerned belts are an consumable iteam, I get my belts from car places like Bursons, I'm on our 3rd set, one per year for us.

I've had to replace the belts only once in two years of fairly regular workload, and I think they wore out because I had overtightened the tension. In any cae, I agree with the other submitter - they are are designed to be serviceable items, and replacing 'em from time to time is expected rather than a design flaw.

You want the Gates 6823 Powerated belt. It's 2-sided kevlar v-belt, 23" x 1/2". There are two of these in the machine and I recommend replacing them at the same time.

When I'm using the C7 I have varied diameters to chip, I use mostly green, but I'm unable to answer your testing question with the accuracy you are asking for, I use the C7 heavily on our property for domestic use, and it doesn't disappoint.

Depends. Softer green wood is easily handled at 7cm without stopping, older dry hardwood takes a bit more time, and you may have to "feed" a 3m long branch a bit at a time to keep the rpm's up.

I've gently fed in 10cm branches, and the chipper will handle it. In that sense, you're doing what the hydraulic rollers do on the huge tree-chomping chippiers :)

Did you end up getting one? if so how was it on the fronds?

My Hansa will basically spit wet leaves out untouched... at best it will bust them in half. It will obliterate dry leaves though

No problems with leafy greens, although *very* watery weeds can occasionally form a gooey mush which needs to be scrapped out from the outlet shoot. I now just let these sit a few days prior to shredding.

No problems with sloshy stuff. We were operating for over an hour in moderate rain, shredding a mixture of fully grown yuccas and wet hedge clippings. Water started streaming back down the outside of the chute but the machine never blinked. With heavy stuff you may have to control the feed in rate so that the disc keeps the momentum it needs to chop the wood.
