Cutting Blades; Clutch Adjustment - Husqvarna W548 Manual Del Operador

MAINTENANCE

Cutting Blades

For the best mowing effect, it is important that
the blades are well sharpened and not damaged.
Replace blades that have been bent or cracked
by hitting obstacles.
Let the service workshop decide whether a blade
with large nicks can be repaired/ground or must
be replaced.
CAUTION! Blades are sharp.
Protect hands with gloves and/
or wind heavy cloth around the
blades before handling.
IMPORTANT Special blade bolts are heat
treated. Replace with a Husqvarna bolt if
required. Do not use lower grade hardware
than specified.
Checking for Bent Blades
1. Park on a level surface and engage the park
brake.
2. Measure the distance between the blade tip
and the ground surface.
3. Rotate the blade 180° and measure the same
distance again.
4. If the difference between the two blade
measurements is more than 1/8" (3 mm), a
blade must be replaced.
5. Repeat on the other blade.
Replacing the Blades
1. Secure the blade with a wooden block to
prevent rotation.
2. Remove the bolt, blade and spacer from the
spindle shaft.
3. Install the replacement blade, reversing the
order of removal.
4. Remove the wooden block.
IMPORTANT Blade sharpening of must be
carried out by an approved service workshop.
Balance the blades after sharpening.

Clutch Adjustment

If the clutch fails to engage or disengage correctly
or makes unusual noise, it may need adjustment.
Stop the engine and let the mower cool. Check
the inspection slots and air gaps. See a service
workshop for adjustments.
Hardware
Check daily. Inspect the entire machine for loose
or missing hardware.
Cleaning
Regular cleaning, especially under the mower
deck, will increase the machine's life-span. Clean
the machine directly after use (after it is cooled),
before the debris sticks.
Do not spray water on the top of the mower deck.
Use compressed air to clean the top side of the
mower deck. Do not use a high pressure washer
or steam cleaner. Do not spray the engine or
electrical components with water.
Do not rinse hot surfaces with cold water. Let the
mower cool before washing.
