Adjusting the Chain Oil
Discharge Rate
To check the chain oil discharge rate:
1.
Position the nose of the guide bar about eight
inches (20 cm) from a smooth surface.
2.
Run the engine wide open for 30–60 seconds.
You should see a light oil spray on the surface.
The chain oil discharge rate is controlled by the oil
discharge adjustment screw on the top of the pruner
head (Fig. 14).
IMPORTANT: Shut off the engine before
adjusting the oiler.
•
Turn the discharge adjustment screw
counterclockwise to increase the chain oil
output.
•
Turn the discharge adjustment screw clockwise
to decrease the chain oil output.
Air Filter
Maintenance Interval
•
The air filter should be cleaned daily, or more
often when working in extremely dusty
conditions.
•
Replace after every 100 hours of operation.
Air Filter Cleaning
1.
Loosen the knob and remove the air filter cover
(Fig. 20).
2.
Remove the foam ring and filter screen from the
air filter cover (Fig. 20).
3.
Clean the foam ring and filter screen with warm,
soapy water. Let the screen and ring dry
completely.
4.
Apply a light coat of SAE 30 motor oil to the
foam ring and squeeze out all excess oil.
5.
Reassemble the filter screen and foam ring to the
air filter cover (Fig. 20).
IMPORTANT: The air filter screen is
designed to fit into the air filter cover ONE
WAY ONLY. Make sure the cutouts in the
screen fit onto the matching plastic posts in
the air filter cover. The fit should be snug
(Fig. 21).
6.
Reinstall the air filter cover and tighten the knob
(Fig. 20).
Fuel Filter
Maintenance Interval
The fuel filter should be replaced after every 100
hours of operation.
Fuel Filter Replacement
The fuel filter is attached to the end of the fuel
pick-up hose inside the fuel tank (Fig. 22).
To replace the fuel filter:
1.
Make sure the fuel tank is empty.
2.
Remove the fuel cap.
3.
Using a wire hook, gently pull the fuel filter out
through the fuel filler opening (Fig. 22).
4.
Grasp the fuel hose next to the fuel filter fitting
and remove the filter, but do not release the hose.
5.
While still holding on to the fuel hose, attach the
new fuel filter.
6.
Drop the new fuel filter back into the fuel tank.
7.
Make sure that the fuel filter is not stuck in a
corner of the tank, and that the fuel hose is not
doubled over (kinked) before refueling.
