MAINTENANCE

Drive wheel
Replacing the drive wheel
• Lock the axle using the locking button.
• Loosen the centre screw and remove the washer.
• You can now lift off the drive wheel.
Drive belt
Tensioning the drive belt
If the drive belt slips, it must be tensioned. The tension of a
new drive belt must be readjusted after one or two tanks of
fuel have been used.
When the machine is equipped with a friction retarder, a
scraping sound can be heard from the bearing housing when
the blade is turned by hand. This is quite normal. Please
contact an accredited Husqvarna workshop if you have any
questions.
The drive belt is enclosed and well protected from dust and
dirt.
• Dismantle the cover and loosen the belt tensioning screw.
• Press on the belt tensioner with your thumb to tension the
belt. Now tighten the screw holding the belt tensioner.
Replacing the drive belt
• Dismantle the cover and loosen the belt tensioning screw.
Push back the belt tensioning roller and install a new drive
belt.
NOTICE! Replace the drive wheel when fitting a new blade.
A worn drive wheel can result in the blade slipping and
becoming damaged.
Inadequate water flow drastically shortens the life of the
drive wheel.
!
WARNING! Never start the engine when the
belt pulley and clutch are removed for
maintenance. Do not start the machine
without the cutting arm or cutting head
fitted. Otherwise the clutch could come
loose and cause personal injuries.
NOTICE! Make sure that both belt pulleys are clean and
undamaged before a new drive belt is fitted.
