Two-Piece Shaft; Air Filter; Gear - Husqvarna 535FBX Operator's Manual

5 Slide the drive shaft back into the sleeve. Make sure
the shaft engages correctly by turning it and pushing
at the same time.
6 When the axle is correctly fitted in the cover, the end
of the axle should align with the edge of the cover.
7 Fit the drive axle cover in the shaft. Twist the shaft
back and forwards while pushing it in.
8 Tighten the carriage bolt.
9 Make sure the wire cover is not twisted around the
flexible axle.

Two-piece shaft

The drive shaft end in the lower shaft should be lubricated
with grease every 30 hours. There is a risk that the drive
shaft ends (splined coupling) on models with two-piece
shafts will seize if they are not lubricated regularly.
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts.

MAINTENANCE
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.
If the machine is used in dusty conditions the air filter
should be soaked in oil. See instructions under the
heading Oiling the air filter.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48.
The filter oil contains a solvent to make it spread evenly
through the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour
off the excess before fitting the filter to the machine. Never
use common engine oil. This would drain through the filter
quite quickly and collect in the bottom.

Gear

Check that there is grease in the gear housing, and fill
with new grease if necessary. This should be done
approximately every 6 months. Do as follows:
