Allow only persons who understand this

Manual to operate your blower.

To receive maximum performance and

satisfaction from your STIHL blower, it is

important that you read and understand

the maintenance and safety precautions,

starting on page 3, before using your

blower.

Contact your STIHL dealer or the STIHL

distributor for your area if you do not

understand any of the instructions in this

Manual.

!Warning!

Because a blower is a high-speed tool,

some special safety precautions must

be observed as with any other power

tool to reduce the risk of personal injury.

Careless or improper use may cause

serious or even fatal injury.

STIHL's philosophy is to continually

improve all of its products. As a result,

engineering changes and improvements

are made from time-to-time. If the

operating characteristics or the

appearance of your blower differs from

those described in this Manual, please

contact your STIHL dealer for

information and assistance.

My Stihl BR420/420C has after 15 years developed a gasoline leak. I fill tank with gasoline. Next day it’s empty. I removed tank, cleaned it up and inflated the tank with air compressor. Tank holds air without air leaks. Cleaned fuel lines. So no broken areas.
Can someone advise me on where to look and what to replace? Submitted on 1-12-2021 at 02:11
