D. CHAIN
TENSION
• Chain tension isvery Important:
_A
loose chain willwear the bar and itself.
-- A loose chain can jump offthe bar while you are
cutting
-- A tightchain can damage the saw and/or break.
e. The chain stretches during.use, especially when
new. Check tension:
-- each lime the saw is used
--more
frequently when the chain is new
--as
the chain warms up to normal operating
temperature.
&WARNING.
r_VOld accidental sta_ing. Always. unplug the _..I
'
Irrom the power source before adjusting chain l
tension,
i
• It is recommended that the saw be turned upside
down for chain tensioning,
• Chain tensioning procedure:
NOTE: The bar clamp nuts must be no more than
finger tight to tension the chain correctly.
1. Hold the saw and turn the AdjustingScrew clocl<.
wise _
until the Tangs on the chain enter the
Guide Bar Groove. Figure 13 (inset).
NOTE: To tighten chain, turn the adjusting screw
clockwise ,,--._. To loosenchain, turn the adjusting
screw counterclockw_se_l[-"_. Figure13.
2. With your g_oved hand, "snap" the chain several
times by pulling down and. letting go of'the_chain:: -
Figure 14.This action removes some ofthe stiffness
in the chain.
3. Turn the Adjusting Screw clockwise.,,--_
until the
chain tie-straps sag 1116"below the bar railS. Figure
!4 (inset).
E. BAR AND CHAIN
OIL
. • The gut_lebal' and cutting chain require con-
tinuous lubrication in order to remain in operating
•condition.
-- Lack of oil will quickly ruin the bar and chain.
Too little oil will cause overheating shown by
smoke comingfrom the chainand/ordiscoloration
of the guide bar rails.

ill! the oil tank. Clean SAE30W oil may alsobe
:used. Never use waste oil for this purpose.
1. IMPORTANT POINTS
a: Fill the oil tank every time you use the saw
and recheck after every 15 minutes of use.
See "Specifications"
for oil Cap location.
b. Wipe off surfaces beforefilling with oll toavoid

and causingdamage.
c. Use a funnel to fill the tank. Pour slowly to
allow air to escape, Wipe up all spills. Do not
use the saw until itis wiped clean and iscom-
pletely dry fromspilled oil
d. Replace the otl cap securely to ensure pro-
per operation of the oiler.
e. Checktheotllevellndicatorfrequenttydur.
ing use. Locate the indicator in the saw frame
just below and behind the front handle. Figure
15. If of! is not visible in the slot when saw is
upright on a level surface, the tank requires
filling.
4. Hold the saw and.tighten the Bar Clamp Nuts with a
9116"wrench.
5. Recheck tension.

before storing. It is'normalfora small amount
ofoil todrip off the bar and chainwhen the saw
is not in use. The excess oil should be wiped
from the saw before storing.
USING THE MANUAL OILER
Your saw is equipped with an oiler actuator/cap
whioh manually suppliesoil.tothe b_ andchain.
Fig uce"15. T he oiler actuatoi'/cap must be usei_
i'egularly andoffen_enough to maintain a thin
film of oil on the barand chain while the saw is
cutting. It is recommended that the oiler
actuator/cap beoperated six(6) times aminute
and held 'for approximately three (.3)seconds
each time it is pressed.
a. Operate the oiler bypressingclown on theoiler
actuator/capwith yourright thumb. Figure 15.
b. Be sure that you continue to grip handles
firmly while usingthe oiler actuatortcap.
