STORING CHAIN SAW
CA| II"T'll#_h|. Never store a chain l
n_L.#ae_,#il, saw for longer than
301
days without performing the following proce-I
dures. J
Storing a chain saw for longer than 30 days requires stor-
age maintenance, Unless the storage instructions are fol-
lowed fuel remaining in the carburetor will evap.orate
leaving gum-like deposits, This could lead to difficult start-
ing and result in costly repairs.
1, Remove the fuel tank cap slowly, to release any pres-
sure in tank. Carefully drain the fuel tank by running,
the unit dry or by tipping the motor housing/fuel tank
over and draining oilYfuel mixture into a container with
the same 2-cycle fuel mixture,
2. Start the engine and let it run until the unit stops to
remove fuel from carburetor,
3. Allow the engine to cool (approx. 5 minutes),
4. Using a spark plug wrench, remove the spark plug,
5. Pour 1 teaspoon of ctean 2-cycle oil into the combus-
tion chamber. Pull starter rope slowly several times to
coat internal components. Replace spark plug (Fig.
36).
NOTE: Store the unit in a dry place and away from possi-
ble sources of ignition such as a furnace, gas hot water
heater, gas dryer, etc.

REMOVING A UNIT FROM STORAGE
1. Remove spark plug.
2. Pul! starter rope briskly to clear excess oil from com-
bustion chamber.
3. Clean and gap spark plug or instatl a new spark plug
with proper gap,
4. Prepare unit for operation.
5, Fill fuel tank with proper fuel / oil mixture. See Oil and
Fuel Information.
GUIDE BAR MAINTENANCE
Frequent lubrication of the guide bar (railed bar which
supports and carries the saw chain) sprocket tip is
required. Proper maintenance of the guide bar, as
explained in this section, is essential to keep your saw in
good working condition,
Sprocket Tip Lubrication
CAUTION:
The sprocket tip on
your new saw has
been pre-lubricated at the factory. Failure to
lubricate the guide bar sprocket tip as
explained below will result in poor perform-
ance and seizure, voiding the manufacturer s
warranty.
Lubrication of the sprocket tip is recom-
mended after 10 hours of use or once a
week, which ever occurs first, Always thor-
oughly clean guide bar sprocket tip before
lubrication,
A lubrication gun (not included) is recommended for
applying grease to the guide bar sprocket tip, The Lube
Gun is equipped with a needle nose tip which is neces-
sary for the efficient application of grease to the sprocket
tip.
.............. Fig. 37
To lubricate the sprocket tip:
1. Move the STOP switch up.
NOTE: It is not necessary to remove the saw chain to
lubricate the guide bar sprocket tip. Lubrication can be
done on the job.
2. Clean the guide bar sprocket tip.
3. Using the Lube Gun (not included), insert tip of lube
gun into the lubrication hole and inject grease until it
appears at outside edge of sprocket tip (Fig. 37).
4, Rotate saw chain by gloved hand. Repeat lubrication
procedure until the entire sprocket tip has been greased.
SAW CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential at all
times to minimize friction with the guide bar.
Never starve the bar and chain of oil. Running the saw
with too little oil wil_ decrease cutting efficiency, shorten
saw chain life, cause rapid dulling of chain, and cause
excessive wear of bar from overheating. Too little oil is evi-
denced by smoke, bar discoloration or pitch build-up.
