Gear; Cleaning And Lubrication - Husqvarna 525HF3S Manual De Instrucciones

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

There is a grease nipple for filling lubricant on the gear
housing. Use a grease gun to fill with grease. This should
be done after every 60 working hours. Use Husqvarna's
special grease.
Use Husqvarna's special grease.
CAUTION! The gear housing must not be filled
completely with grease. The grease expands as the
machine heats up during operation. If the gear housing
was completely filled with grease it could damage the
seals and lead to leakage of grease.
The grease in the gear house does not normally need to
be changed except if repairs are carried out.
