So I have some tree trimming to do and what better excuse to buy a new tool? I picked up a Bosch RS7 (11 amp) reciprocating saw at Lowes for $69.99 on sale.
I’m pretty impressed with it. I cut off a pretty large branch off of a 30year old cottonwood tree and am in the process of chopping it up. All of the small’ish parts are done. To illustrate the size that I have left I got 9” pruning blades and I’m going after some 12” in the morning because they won’t go through to the other side, though you can “roll” around the outside circumference and get through. It is probably around 10-11” at it’s biggest point. I really need a chain saw but one project just doesn’t justify one and for the rental cost I get a new tool. I literally only have like 10 cuts this big to do, all others are on smaller parts and no problem at all.
Does anyone know what the duty cycle is or where to look it up? The saw is handling these cuts fine except for one thing. The gear drive is getting quite hot if I don’t stop and let it cool down. Almost too hot to hold with mechanics wear leather gloves. The motor is not balking one bit though, 11 amps is having no issue with the cuts and it has a good fan and is staying cool, I can’t imagine why one would need 13-15amps with this 11amp saw running like it does. I think the heat is transferring up the blade into the housing since it is essentially buried in the log and unable to dissipate much heat. Each cut is taking about 3 to 4 minutes going easy on the pressure. I apply a little pressure and rock the saw to keep the dust rolling out of the cut and not clogging up things. I’m doing a couple of cuts and giving it time to cool down. I guess my question is what is the duty cycle of these things and just how tough are they? They appear to be pretty dang good but I don’t want to push it too much.
Here is the saw:
