Adding bar and Chain Oil: initial Use

This chainsaw comes from the factory with the chain oil reservoir
empty. Refer to Adding Bar and Chain Oil instructions in the
Maintenance section.

Adjusting the Chain Tension: initial Use

The saw chain must be properly tensioned before attempting
to start or operate the chainsaw. The saw chain may also
require additional tensioning as the saw chain heats up during
operation. Refer to Adjusting the Chain Tension instructions in the
Maintenance section.
Testing the Chain Brake

Always activate the chain brake slowly and deliberately. Keep
the saw chain from touching anything. Do not let the chain saw
tip forward.
Always test the chain brake before using the chainsaw.
1. Set the chainsaw on a flat, level surface.
2. Make sure the chain brake lever is pulled back in the
disengaged position (Fig. 1).
3. Start the chainsaw. Refer to Starting Instructions in the
Starting and Stopping section. Maintain a proper grip. Refer
to Holding the Chainsaw in the Operation section.
4. While the chainsaw is running, squeeze the throttle control
to 1/3 throttle and then engage the chain brake by pushing
the chain brake lever forward with the left hand (Fig. 1). The
chain should stop moving abruptly.
IF... If the chain stops moving, the chain brake is working
correctly.
IF... If the chain does not stop moving, have the chainsaw
serviced by Champion or other qualified service dealer.
5. Stop the engine and return the chain brake to the disengaged
position. Refer to Stopping Instructions in the Starting and
Stopping section.

Oil and fuel Mixing instructions

The use of old and/or improperly mixed fuel is the most common
cause of performance problems. Use only fresh, clean unleaded
gasoline. Follow the instructions carefully for the proper gasoline/
oil mixture.
The chainsaw engine works with 10% or less ethanol blended
gasoline. When using ethanol-gasoline blends there are some
issues worth noting:
– Ethanol-gasoline blends can absorb more water than gasoline
alone.
– These ethanol blends can eventually separate, leaving water
or a watery goo in the fuel tank, fuel lines, fuel filter and the
carburetor. This compromised gasoline can be drawn into the
carburetor and cause damage to the engine and or create
potential hazards.
– Any damages or hazards caused by using ethanol blended
gasoline higher than 10% by volume, improperly stored
gasoline, and/or improperly formulated stabilizers, are not
covered by the manufacturer's warranty.
– When a fuel stabilizer is used, confirm that it is formulated to
work with ethanol-blended gasoline.
– It is recommended to drain the fuel after each use and run the
engine to starvation. See Storage instructions for extended
non-use.
DO NOT use E15 fuel in this chainsaw.
Using fuel containing greater than 10% ethanol will damage
this engine and void the warranty. Always use E10 or less to
protect the engine's power.
Using Fuel additives
Always use a 2-cycle oil designed for air-cooled engines and
mix it with a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent. Add 0.8 oz. (23mL) of fuel additive per gallon of fuel,
according to the instructions on the container. NEVER add fuel
additives directly to the chainsaw's fuel tank.
mixing the Fuel
For proper engine operation and maximum reliability, pay strict
attention to the gasoline and oil mixing instructions on the
2-cycle oil bottle. Using improperly mixed fuel can severely
damage the engine.
