Help with old Sachs Dolmar 153

[Big Sach]

Hello Im new to saws but I recently bought a Sachs Dolmar 153 with 24 inch professional Windsor roller tip bar and Windsor 3/8 semi chisel chain. 90 bucks Cdn!!! I got a saw this big as a first saw because I live close to a pole yard which is where i get firewood it is mostly Douglas Fir. The poles are big, sometimes 18 inch diameter or more so I figured I'd need a saw this big to cut through that stuff.

The saw runs very strong. But I have problems with bar oiling. The oil hole in the bar always gets clogged up with wood debris and then the chain doesn't get enough oil.

Can I adjust the auto oil to "flow" more, so that it can maybe overcome the constant blockage?If so, where is the adjusment screw? I can't find it.

Should I run lighter winter bar oil to try to get more flow?

How come this saw doesn't have a chain brake? They didnt put them on saws back then I suppose.I guess if it ever kicks on me Im a dead :censored:

Thanks in advance for any help.

Just got one of these this summer,paid more than that! Goood buy!

Had problems with the oiler on mine too, figured out that the bar on the saw had the oiler hole in the wrong place. built for some other saw?Drilled a couple of holes in the bar, works great now. I've got a 33" hardnose Cannon bar, oils lots. The screw for the oiler can be accessed from the front of the saw, reach in with a straight screwdriver by the bottom left of the muffler. Should be labeled, maybe on the muffler if I remember right.

Let us know if you don't find it!

Almost forgot, mine has no brake either, but the picture on Mike Acres site show one with a brake. Must be around...........

Post some pictures. Those older Sachs were good saws.

Thats a pretty big saw for someone new to them. If you are only cutting 18" diameter wood, you are way overgunned for it. You stole that saw if you only paid $90CDN for it.
Check to ensure the bar mount is the correct one for the saw. As PWB mentioned, the oiler hole may not be lining up properly. If wood debris is clogging it up, you may have a slightly dull chain when cutting that is producing excess fine dust. Cutting correctly, it should produce mostly chips, not dust.
As to whether you need winter bar oil or not, it depends upon where you are at. On the coast, no you probably don't need it. In the interior, you likely don't need it, but it won't hurt either. I know lots of places you don't really have much choice, because they only sell winter weight in the winter, and summer weight in the summer. So unless you have it sitting around from the summer, you may have to buy winter weight.

oiling

All good information.

Man you guys are good You are also very right. When I had the saw apart this past summer I noticed that the bar"s oil hole and saw oiler tube do NOt line up . I have a mechanical background so I did think of drilling another hole but if I drill the new hole to line up properly with the oil tube then the top of the new hole will "break " through the bottom of the bar groove. My concern was that the chain runners might catch in this hole, Or is this the way its supposed to be anyways so that oil flows into the bar groove?(haven't looked at other saws yet)


Also I do know this is a huge saw for a first timer 100cc I think it is, but I have alot experience around other dangerous power tools and I always respect what im working with and having run this saw alot this past summer I'ts got my respect . This things a beast! Also i'm not planning to go out and start felling.The chain is very sharp because I asked an ol timer to teach me how to do it and I bought the files and a jig so now I do get nice big chips.



Question for TIMBER PIG (sounds like your experienced cutter)I dont think this saw ever had a chain brake on it from factory because it must be made prior to 1980. Should I consider finding a chain brake and putting one on if thats possible, or keep doing what I'm doing and run it with respect and full safety gear. A chain brake isn't neccessarily going to save my ass if a saw this big kicks back anyways is it?

Pictures are coming....

 

[PWB]

You're right, it's 100 cc. According to Mike Acre's website, saw was introduced in 1986. He does have a picture of one on the site with a chainbrake, although mine doesn't have one. Besy bet is to start haunting some of the shops in the area looking for a parts saw with a brake. Most of the parts for the saw have been discontinued by Dolmar, so I don't thing you'd be able to order a new one. I've been wrong before though..........

I've been told that at one time WSIB would let you use a saw that big without a brake if it had a bar at least 28" long. THe longer bar will tend to kick up over your head instead of into your face. Big thing is just make D**mned sure you keep the tip away from anything on the other side of your cut! Get someone who cuts a lot, preferably someone with training, to spend an hour or two with you while you cut. You'll learn a lot.

The 153 was not introduced in 1986, it was discontinued in 1987. I forget the year it came out. I can go back to a 1981 parts list and it is shows a chain brake for the 153. If you would like I can email you the copy of the parts list. You must now that most of the parts for the 153 have been discontinued and are no longer available. There may be some laying around in dealers. Power Source Canada in Vancouver, BC is the new Dolmar Distributor in Canada.
The 153 did use a unique bar mount that was for Sachs-Dolmar saws only. Sandvik Windsor referred to as a DCX mount and we still sell the 25" Sprocket Nose Replaceable bar for that saw. Part number is 431063012.
I too would have to agree that the 153 is a beast and some serious over kill for 18" timber. But to each his own. Be careful with that saw and no chain brake.

Weird thing that posted twice!!! Computers - go figure!

When you say Sandvik Windsor -if thats the company out of Ontario Canada then thats got to be the bar thats on this saw already. It is stamped Windsor and it is 25'' Sprocket Nose and it obviously fits so it must be the DCX style mount I dont think its been milled out.. Too bad the oiling holes dont line up though but Im fixing that soon.

I would really appreciate a parts list emailed that be great.

So there's a chance Power Source in Vancouver might have a chain brake sitting around or know where one is thats encouraging. Do you have a contact there at all?

1980 mandate

Also if the 153 was introduced prior to 1980 and mine was made before that then it would make sense it has no chain brake because wasn't 1980 the year that chain brakes became mandatory?

 

[Dolmar_Tech_Mgr]

Windsor makes many bars with many mounts but even thought it fits over the studs doesnt mean it is a DCX mount bar. Check the bar there should be some numbers on it close to the motor end of the bar.
I will send you a private message with the parts list attached. I know that Power Source Canada will not have that part there as they have only been the distributor for 6 months.
I was up there a few months ago and can not remember the gentlemans name, but it is a small office and there are only a few guys working there some they will be able to assist you.
The parts that were still available for the 153 were scrapped back in 1995 and your only avenue for finding a chain brake for that saw would be the Dolmar dealer network in the USA and Canada. The arboristsite would be the best place to post looking for a part that old.
Not sure of dates prior to 1985 as that is when I went to work for Sachs-Dolmar in Shreveport, LA.

 

[TimberPig]

If the oil hole doesn't line up, I would check to make sure it is the correct mount. There will be a series of numbers and letters stamped in the bar near the mount. Post that and you will soon know if you have the correct bar or not.

I doubt Power Source has a cover and brake sitting around if they are the new distributor. They likely don't know where once is either if they are new in distributing the line either. You will have to get extremely lucky to find an old Dolmar dealer who has one sitting on their shelf, or look for a used one.

It was sometime around 1980 that chainbrakes became standard. You used to be able to use a saw without a break still so long as it had a 27" bar or longer, but they changed it a year or so ago and frown on it now.

The idea of the brake isn't totally to save you from the saw kickback, as it is to reduce the severity of injury by stopping the chain and allowing you more time to react. A saw with a brake is much safer than one without it, but safe use of the saw, and being particularly careful to keep the upper quarter of the saw nose out of the wood are better than a brake for keeping your butt intact.

Chainsaws are commonly regarded to be very close to the most dangerous tool you can legally buy freely in an open market. Full safety gear and some instruction form a qualified person will go a long way to keeping you from being injured, and the instruction will help make your cutting more productive, when they teach you about pressure points, and ways to avoid pinching your bar.

 

[Dolmar_Tech_Mgr]

Here is the latest parts list for the 153. Both copies I have show the chain brake.

 

[Dolmar_Tech_Mgr]

You know chain brake were not required but you had to have a least 2 methods to reduce kickback. Some saws used a gaurd tip on the bar that did not all the tip of the bar to contact the material. All manufacturers use low kick back chain on saws smaller than 60cc as required by OSHA. Even today you will see saws for sale that dont have a chain brake but use the guard tip on the bar.

 

[TimberPig]

I was speaking more specifically to BC and Canada. I don't believe they are allowed to sell them without a chain brake new anymore up here.

 

[Big Sach]

So should I hunt for a chainbrake for this saw that I'm probably never going to find anyways ? Or use it sensibly watch my tip control and always gear up? Also I've got the throttle set so that if you release it all the way the saw dies. Sort of a cheesy kill switch if you will.

Why is it that only 60cc and smaller saws have lowkickback chain ? Is it because the bigger saws have the power not to "bog" and catch?

 

[PWB]

Thanks for the correction about the dates. Mike's site is good, but not infallible. I'll be downloading that parts list too! If you find two brakes floating around, I'd be interested in one if it's not too dear.

BAr

The bar is stamped with the following:

Windsor J53T

Right Bar or wrong bar?
