Rollers - Adjustment/Inspection - Husqvarna K3600 Mk II Workshop Manual

ROLLERS – ADJUSTMENT/INSPECTION
The rollers must always be adjusted following:
– changeover to a new blade
– changeover to another used blade
– replacement of guide or support roller
Always check the adjustment whenever the support roller guard has
been removed and refitted.
IMPORTANT: When adjusting the rollers, the knobs must be
screwed out – but not out fully to its end position as this will stop the
engagement roller rotation.

Inspection
At least once during the
life of the blade
The inspection is conducted in
the same way described above.
Correct adjustment
It is very important that the rollers are
correctly adjusted in order to ensure
machine function and to minimise wear.
To be correctly adjusted, the rollers
must be set to the blade with no clearance.
Excessive contact increases roller wear
and results in deformation on the blade
that will, in a worst case scenario, lead to
the blade breaking.
Insufficient contact will result in the
blade being unstable. In extreme cases,
this may lead to the blade leaving its
track.
Function
The support rollers are fitted on levers in
the support roller guard. The position of
the lever is determined by the adjuster
screws (A). The locknuts (B) lock the
lever in position.
Adjustment
Important – knobs screwed out
Roller adjustment must always be per -
formed with the knobs screwed out.
Undo the locknuts (B).
The best way to inspect the adjustment
is to tighten the locknuts slightly before
starting the adjustment process.
Rough adjustment
Rotate the blade by hand and screw in
the adjuster screws (A) until the rollers
rotate.
Fine adjustment
Fine adjust until you reach a position
where you can easily stop the rotation of
the support rollers with your thumb
(lower picture).
