Inspecting The Blades; Replacing The Shear Pin - Jonsered FR2115MA Operator's Manual

Inspecting the blades

It is important that the blades are undamaged and
well-ground to give the best mowing result.
Check that the blades' mounting bolts are
tightened.
IMPORTANT INFORMATION
Replacement or sharpening of the blades
should be carried out by an authorised
service workshop.
The blades should be balanced after sharpening.
Damaged blades should be replaced when hitting
obstacles that result in a breakdown. Let the
servicing dealer judge whether the blade can be
repaired/ground or must be discarded.
IMPORTANT INFORMATION
The blades on the double blade Mulching unit
should always be set relative to each other as
illustrated, with a 90° angle between the
blades. Otherwise the blades can collide and
cause damage to the mowing deck.
Replacing the shear pin FR 2113 MA,
FR 2115 MA
The blades are fitted with a shear pin to protect the
Mulching unit and its drive when colliding with
obstacles. A domed, spring friction washer is fitted
to each blade bolt. The washer must always be
replaced with a new washer when replacing the
shear pin. Otherwise the shear pin can break
causing the blades to collide.
Only use original spare parts. A set containing a
blade, shear pin and friction washer can be
purchased from your dealer.
