Does anyone know how the washers are supposed to work in a Jonsereds 70e brake assembly? Is there a certain alignment of the washers that matters or certain # of washers? I've got one that I can either put together with the brake engaged or not engaged (but not functional). I'm struggling with how to set it up so it can be both applied and released.
The washers (shims) are all the same or should be. There is no lock on the brake.
I didn't find they were very effective on my 801.
From a repair manual,
KICKBACK MECHANISM. Models
451E, 451EV, 50, 51, 52E, 521EV and
70E are equipped with a kickback
mechanism to stop the chain should the
saw kickback while cutting. Mechanism
is activated when operator's hand
strikes kickback bar. Brake shoe (22-
Fig. J12 or 18-Fig. J13) is forced
against the clutch drum to stop chain.
The ignition on Models 50 and 51 is also
grounded to stop the engine.
On all models except Models 50 and
51, there should be 0.5-1.0 mm
(0.020-0.040 in.) between brake shoe and
clutch drum with kickback lever in rest
position. Add additional shims to shim
