The introduction of the PM1000 into Australia seen this as McCulloch's new big saw
at 100cc, personally i sold many of these being a great sale especially to those
farmers wanting a big saw to rip fence posts a job they done exceptionally
well giving many many years of dependable service. Not long after there release intial problems included poor auto oilers and fine saw dust getting through the origional filters and causing problems with wear and a build up in the oil pump gear .... both problems were soon overcome Australian hardwoods produced a very fine saw dust. Most of this model i sold with 24" bars and .404 pitch chains. All the early models released in Australia had a half wrap front handle. The later versions had a 3/4 wrap and a brace from the front handle to the rear of the pistol grip. All PM1000 came with both auto oiling and a manual thumb operated oil pump. These saws with take the large mount cutter bar of the SP125 with spacers for the difference in bar stud size Fuel mixture ratio is 40-1 |

Only the later P100's and Super P100's had the handle brace |
I pulled the manual and automatic oilers on my PM 1000 and found the o-rings were
as follows: ID OD CS 5/32 9/32 1/16 Manual Oiler 7/32 11/32 1/16 Automatic Oiler Standard BUNA-N (Nitrile 70) o-rings work excellent |
Handle braces Early PM1000 and P100's were not fitted with a brace from the front
to the rear handle i don't personally know when the upgrade took place but i have
seen later PM1000, P100 and Super P100's along with the Jonsereds 1020 fitted
with them. |

If you look at the provision for a decompressor the casting has it but its not drilled
theres even a top shroud with a rubber bung where it would be fitted but
no decompressor button. |
P100 with the problematic Partner Thyrister electronic ignition. |
Airfilters for the Australia PM1000 where changed soon after the saws release as
the european filters proved hopeless at keeping Australian hardwood fine sawdust
from being ingested into the engines. Use the double flocked air filter |
At long last an answer The Differences are The Super P100 has a chainbrake a wrap around handle and 2 spiked bumpers |
PM1000 later version notice the brace from the front to the rear handle |
Early PM1000 no handle brace but had chainbrake |
Final update April 7th 2011 |
Notice these have a Nickel / silicon plated Bore |
Forerunner to the P100 P100 Super PM1000 and Jonsereds 1020 the Partner 440 |
