sugahari

Hi There, The biggest bar i have run on my 880 is a 36inch, but i have just recieved my sugahari 46inch this morning for some big rounds and milling. Does anyone have some advice on starting its cutting life right....any dos and donts for the first cuts?

 

thanks in advance.

Nothing different springs to mind . All my saws are on those bars . I find them much harder wearing than anything else I have tried including Canon .

Grease the nose sprocket regularly. Other than that superb bars.

Put some oil in the groove before first run if you think to but not too important if the oiler is good.

I would say the opposite . I stopped greasing nose sprockets a few years ago and since stopping have had none fail . Prior to stopping I had a few explode albeit on cheaper chocolate Husky bars . I think the grease allows grit and crud to stick to it jamming up the sprocket .

Yep - nose sprockets on these need to be regularly greased in the correct way.

 

 

Instructions as below:

 

Sugi bars need to have the bar noses greased every 6 hours of work.

 

 

• Clean out grease hole
  
• Couple of pumps of grease, turn nose sprocket, couple of pumps, turn nose sprocket...
  
• Same other side
  
• Any resistance as you are doing this or if you can feel debris inside as you turn sprocket keep greasing until turns smoothly and evenly
  
• run chain gently for a minute or two (you can blow a nose sprocket by revving hard after greasing as the hydraulic effect of the grease can cause failure)
  
• After running in use as normal

It's a million dollar question really - but I always advise regular greasing purely as it says in on the bar packaging - I have asked a few manufacturers about this - it's safer not to grease but you do risk earlier nose failure. That's not to say it will happen - just more chance of it happening.

 

 

I've had x5 sugi noses back that failed earlier than they should have - all as dry as a bone - not had any fail that have been greased so I think they do better greased than un greased.

 

 

But if you've had no probs up to now stick with what you are doing - I expect there's a lot of variables at work and it's not just a straight answer of 'this is right and this is wrong' only - this is what works for me!
