Spark Plug; Replacing And Adjusting The V-Belt; Replacing And Adjusting The Centre Belt - Husqvarna WC 48 Se Manual De Instrucciones

Assembly
• Place the cutter with the friction washer against the cutter
bracket. Make sure the cutter centres correctly on the
shaft. To avoid vibrations, place the mower cutter so that
the cutter bracket marking can be seen on the sides of the
cutter.
• Fit the washer and tighten the bolt correctly. The bolt
should be tightened with a torque of 45-60 Nm.
• Pull the blade around by hand and make sure it rotates
freely. Test run the machine.

Spark plug

NOTICE! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/
cylinder.
• If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking other steps.
• If the spark plug is dirty, clean it and check that the
electrode gap is 0.5 mm. Replace if necessary.

Replacing and adjusting the V-belt

• Remove the protective cover by unscrewing the screws.
Remove the hubcap on the front wheel by the gearbox,
prize carefully with a screwdriver.
• Loosen the carriage bolt and remove the wheel.
• Remove the belt.
• Fit the new belt and make sure it fits correctly by the ball-
bearing before adjusting the belt.

MAINTENANCE
• Adjust the belt by moving the ball-bearing up or down.
• A new belt stretches and becomes longer, so adjust the
belt again after a few hours of operation.
• Fasten the wheel and the belt cover and test run the
machine.
Replacing and adjusting the centre
belt
The centre belt runs between the engine shaft and the
gearbox.
Adjusting the centre belt
• Unscrew the adjuster screws a few turns.
• Adjust the belt by moving the gear forwards or backwards.
• The belt should be stretched so that it can move 10mm in
the centre. That corresponds to a pull of approx. 3 kg. Use
a fishing scale to check.
• Tighten the adjustment screws properly.
• Check the drive operation, as adjustment of the gear
affects the belt tension in the gearbox.
Replacing the centre belt
• Remove the cutter.
• Loosen the adjustment screws.
• Replace the belt with a new one and tighten the
adjustment screws a little.
• Adjust the centre belt. See instructions under the heading
"Adjusting the centre belt".
• Assemble the blade.
