Bevel Gear; Drive Shaft - Husqvarna 545RXT AutoTune Operator's Manual

CAUTION: A damaged filter must always be
replaced.

Bevel gear

The bevel gear is filled to ¾ with grease at the factory.
Before use, make sure that the grease level has not
changed. Use Husqvarna special grease if it is
necessary to fill up. Do not change the grease in the
bevel gear. Let servicing personnel do the repair of the
bevel gear.

Drive shaft

Lubricate the drive shaft at an interval of 3 months. Let a
service agent help you if you are not sure about the
procedure.
To attach and remove the locknut
WARNING: Stop the engine, use protective
gloves and be careful around the sharp
edges of the cutting attachment.
Use the locknut to attach some types of cutting
attachments. The locknut has a left thread.

• Use a socket wrench with a shaft that is sufficiently
long to let you keep your hand behind the cutting
attachment guard. The arrow in the illustration shows
the area where you can safely operate the socket
wrench.
• To attach, tighten the locknut in the opposite
direction to how the cutting attachment rotates.
• To remove the locknut, turn it in the same direction
as how the cutting attachment rotates.
• Keep count when you remove and attach the
locknut. Replace the locknut after approximately 10
times.
Note: Make sure that you can not turn the locknut by
hand. Replace the locknut if the nylon lining does not
have a resistance of a minimum of 1.5 Nm.
To examine the spark plug
CAUTION: Always use the recommended
spark plug type. Incorrect spark plug type
can cause damage to the product.
• Examine the spark plug if the engine is low on
power, is not easy to start or does not operate
correctly at idle speed.
• To decrease the risk of unwanted material on the
spark plug electrodes, obey these instructions:
a) Make sure that the idle speed is correctly
adjusted.
b) Make sure that the fuel mixture is correct.
c) Make sure that the air filter is clean.
