Fuses; Checking The Cutting Unit's Parallelism; Checking The Blades - Husqvarna Rider Operator's Manual

Fuses

Fuses are located in a fuse holder under the rear battery
cover.
The fuse holder houses three fuses.
• Yellow - 5A, Key switch fuse
• Blue - 15A, Charge fuse
• Green - 30A, Freewheel fuse
Do not use any other type of fuse when replacing.
A blown fuse is indicated by a burnt connector. Pull the fuse
from the holder when replacing.
The fuse is there to protect the electrical system. If it blows
again shortly after replacement, it is due to a short circuit,
which must be fixed before the machine can be put into
operation again.
Fuse on the battery charger.
A glass fuse is fitted to the battery charger.
Replacement must be performed by an authorized servicing
dealer.
Checking the cutting unit's
parallelism
Check the cutting unit's parallelism as follows:
1 Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.
2 Place the machine on a flat surface.
3 Measure the distance between the ground and the front
and rear edges of the cutting unit hood.
The cutting deck must have a slight tilt, with the rear edge
5-7 mm (1/5-1/4") higher than the front edge.
MAINTENANCE AND SERVICE
Adjusting the parallelism of the cutting unit
1 Check the air pressure in the tyres 60 kPa / 0.6 bar / 9 PSI.
2 Loosen the parallelism stay's nuts, the inner nut has a left-
hand thread.
3 Screw out (extend) the strut to lower the rear edge of the
cover.
Screw in (shorten) the strut to raise the rear edge of the
cover.
4 Tighten the nuts after adjustment.
5 On completion of the adjustment the unit's parallelism
should be re-checked.

Checking the blades

WARNING! Wear gloves to protect your
!
hands when working with the blades.
To achieve the best mowing results it is important that the
blades are undamaged and well-sharpened.
Excessive vibration in the machine may be caused by
damaged or loose blades.
• Remove the cutting deck. See the "Removing the Cutting
Deck" section.
• Check that the blades' attachment screws are tight.
• Check that the blades are intact and not damaged.
Damaged blades should be replaced when hitting obstacles
that result in a breakdown.
The blades should be balanced after sharpening.
WARNING! Do not use blades that are
!
cracked, chipped, or otherwise show signs
of damage or severe wear. Replace the
blades. The risk increases if the blades are
poorly balanced.
