A power chain saw is a most useful and efficient woodcutting tool. As in the
operation of other mechanical equipment, however, it requires common
sense handling to provide safety as well as labor saving performance. A few
simple Do's and Don'ts can make all the difference.
Be safe!
Start your saw without help.
Start the saw
on a firm surface.
Turn off your
saw when moving between cuts.
Be su re of your footing and pre·plan a safe exit
from a falling treo.
Watch
out for falling limbs.
Refuel
in a safe place. Guard against fire hazards.
Keep a firm grip on a running saw with both hands.
Beware of "kickback".
Wear close fitting and protective clothing including
safety hat
s, goggles, shoes and gloves.
Obey all laws, rul es and regulations of the cutting
area.
Keep the chain snug on the guide bar.
Keep
all screws and fasteners tight.
Be sorry!
Fail to follow the instructions for operat ion of the
saw in this owner's manual.
Start a saw
on your leg or knee.
Let a moving cha in touch your clothing.
Touch
or try to stop a moving chain with your
hand.
Allow any other person or animal close to a running
saw
or where a tree is being cut down.
Cut with a dull or loose chain.
Smoke while operating the saw.
Spill fuel or sta rt a saw whero you fuel it.
Refuel a
hot saw., (Allow it to cool a few minutes.'
Use any other fuel than that recommended in your
owner's manual.
Run the saw without an exhaust stack, muffler or
spark arrester.
Allow dirt, fuel or sawdust to build up on the engine
or outside
of the saw.
Forget the rules for fire prevention and forest
protection.

Two-cycle engines are lubricated by oil mixed into the gasoline. The correct
ratio of oil to gasoline is very important. Follow the ratio specified in the
FUel Mixture Table. Use only regular grade gaSOline. McCulloch 40:1 Oil is
the best two-cycle motor oil to use. If it isn't available, use any well -known
brand of SAE 40 two-cycle, non-additive, motor oil. Never use dirty or re-
claimed motor oils.
Thoroughly mix the gaSOline and oil in a container equipped with a flexible spout
before filling the fuel tank of your saw. Wipe the fuel cap and the area around
it clean before filling the fuel tame. Do not let dirt get into the fuel tank. Dirt
can seriously damage the engine.

Your chain is lubri cate d with oil from the chain oil tanle Fill the oil tank each
time you fill the fuel tan1e
We r ecommend using McCulloch Chain , Bar and Sprocket Oil which co ntains
additives to reduce friction and wear and to assist in the prevention of pitch
for mation on the bar and chain . If McCulloch Chain , Bar and Sprocket Oil is
not available, use SAE 30 non-additive motor oil at temperatures above 40 and
SAE 10 non-additive motor oil at lower temperatures.
Keep the oil supply container clean. Wipe the oil tank cap and the o il tank
surrounding the fill area clean before filling the oil tank. Do not use dirty or
reclaimed motor oils under any circumstances. Dirt can plug the chain oiling
system. Never operate your saw if the oiler system does not work.
AUTOMATIC OILER ADJUSTMENT
Some Mini Mac 6 saws are equipped with an automatic cha in oiler. adjusted
at the factory for average cutting conditions. Oil now may be adjusted however,
6

to suit individual desires by an adjustment screw at the front of the saw. Turn
the screw clockwise to decrease oil fl ow and counterclockwise to in c reas e it.
The automatic oiler adjust m ent
screw should never be t urn ed more
than a qu arter turn at a ti me without
checking the oil flow after the ad-
justment. Maximum o il flow can
em pty the ch ain o il tan k in ap proxi-
mately ten minutes of cutti ng. Where
increased oil flow is desired for
short periods, it is better to sup-
pl ement the o il flow by mor e frequent
use of the manual oiler button. The
automatic oiler supplies o il when-
ever the engine is running. Long
periods at idle speed can result in
oil puddl es beneath the saw and
wasted oil. It is advisable to turn
the saw off between cu ts unless it is
in almost contin uous us e.

CHAIN TENSION IS IMPORTANT:
A too loos e ch ain can be danger ous - a too tight chain can be expe nsive because
it will wear rut fast.
Even th ough your ch ain is installed , check chain te nsion before you start your
saw. Chain te nsion is correct wh en the chain has a snug fit on the bar rut ca n
sti ll be pu ll ed easily aroun d the bar
by hand. Ch ain is sharp - protec t
your hand when touc h ing it.

Follow these steps to adjust chain
tension:
1. Loosen the bar mounting nut.
See Figure 3.
2. With the bar nose or rounded end
of
the bar held up! turn the ten-
sion adjusting screw clockwise to
tighten the chain. Turn the screw
counterclockwise to loosen the
chain. See Figure 4.
3. When tension is correct! tighten the bar mounting nut while still holding
the nose of the bar up and then recheck chain tension by pulling it around
the bar. Protect your hand from the sharp cutting teeth of the chain.
See Figure 5.
A
chain will lengthen during the first few hours of use. If the chain is hot to
the touch, allow it to cool before checking tension. Keep chain and bar groove
oiled. For more information on chain maintenance, tUrn to page 27.

STARTING & STOPPING
1. Fill the fuel tank with the correct
fuel mixture . Fill the chain oil tank
with McCulloch Chain, Bar and
Sprocket Oil. Pump the manual
oiler lxItton until oil shows between
the chain and the bar at the top of
the bar where the chai n comes Qut
from b ehi nd the clu teh guard.
Figure 6.
2. Make sure the chain has the cor-
rect tension and that the bar is
tight on the saw.
3. Slide the ignition switch to th e ON position.
4. Turn the choke l ever to the fully closed pOSition. A warm engine usually
does not r e quir e the us e of the choke. However, when restarting an ex-
