MAINTENANCE
Tensioning the drive belt
• 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 fully enclosed and well protected from
dust and dirt.
• When the drive belt is to be tensioned, release the bolts
holding the cutting arm.
• Screw the adjuster screw so that the square headed nut
comes opposite the marking on the cover. This
automatically ensures that the belt has the correct
tension.
• Tighten both of the screws holding the cutting head using
a T-wrench.
Replacing the drive belt
• First release the two bolts and then the adjuster screw to
release the belt tension.
• Now unscrew the bolts and dismantle the belt guard.
• Remove the belt from the belt pulley.
• The cutting head is now loose and can be removed from
the machine. Remove the rear belt guard by releasing the
two screws holding the guard.
• Replace the drive belt.
• Assemble in the reverse order as set out for dismantling.
• Check that the guard over the cutting blade is not cracked
or damaged in any other way. Replace when damaged.
Belt pulley and clutch
Never start the engine when the belt pulley and clutch are
removed for maintenance.
Carburettor
The carburettor is equipped with fixed needles to ensure the
machine always receives the correct mixture of fuel and air.
When the engine lacks power or accelerates poorly, do the
following:
• Check the air filter and replace if necessary.
• When this does not help, contact an authorised service
workshop.
IMPORTANT INFORMATION The tension of a new drive
belt must be readjusted after one or two tanks of fuel have
been used.
!
WARNING! Do not start the machine without
the cutting arm or cutting head fitted.
Otherwise the clutch could come loose and
cause personal injuries.
