MIX GASOLINE AND OIL - 40:1 RATIO
1. Approved Mixture — For simplicity and best
engine performance, mix the contents of one
3.2-0unce bottle of Toro “EASY MIX” Two-
Cycle Oil with one gallon of fresh unleaded
regular gasoline. Leaded regular gasoline may be
used If unleaded regular is not available.
Toro Two-Cycle Oil is specifically formulated to
provide superior lubrication, make starting easy
and prolong engine life. If Toro Two-Cycle Oil
Is not available, mix one gallon of gasoline and
3.2 ounces of another high grade two-cycle oil
that has the NMMA or BIA-TCW certification
printed on the label.
NEVER USE AUTOMOTIVE OIL (i.e. SAE 30,
10W30, etc.). TWO-CYCLE OIL THAT 1S NOT
CERTIFIED NMMA/BIA-TCW OR THE WRONG
MIX RATIO BECAUSE THE ENGINE CAN
BE DAMAGED AND THAT WOULD NOT BE
COVERED BY THE TORO WARRANTY.
2. Mixing Gasoline and Oil — Pour correct

amount of two-cycle oil into an approved gasoline
container and add a half gallon of gasoline.
Install cap on gasoline container and shake the
container to mix oil and gas thoroughly. Remove
cap and add remaining amount of gasoline.
IMPORTANT: NEVER USE METHANOL,
GASOLINE CONTAINING METHANOL, GAS-
OHOL CONTAINING MORE THAN 10%
ETHANOL, GASOLINE ADDITIVES, PRE-
MIUM GAS OR WHITE GAS BECAUSE THE
ENGINE FUEL SYSTEM COULD BE DA-
MAGED.
FUEL STABILIZERS WITH ISOPROPYL
ALCOHOL CAN BE USED, HOWEVER. TORO
GAS STABILIZER AND FUEL CONDITIONER
IS RECOMMENDED TO KEEP THE ENGINE
CLEAN AND ASSURE EASY STARTS.
NOTE: Do not mix gasoline and oil in the pro-
duct fuel tank. Oil that is at room temperature
mixes easier and more thoroughly than cold oil.

CENTRIFUGAL CLUTCH
This machine is equipped with a centrifugal
OPERATION
clutch which is designed to engage when
engine speed reaches approximately 3600 -
4200 RPM. This is the point at which the cutter
head begins to rotate. The clutch will slip to
prevent possible engine damage should the
cutter head be prevented from rotating.
Should this situation occur, STOP ENGINE,
remove obstruction and resume operation.
ENGINE OPERATION
1. Allow the engine to run at idle speed a few
minutes to warm up before using.
IMPORTANT: The cutting head should not
rotate at engine idle speed. If cutting head
rotates at idle, decrease idle speed by adjust-
ing idle stop screw. Refer to Adjusting Car-
buretor, page 8.
Note: DO NOT have engine under load during
this warm up period.
2. When starting trimmer engine initially, check
carburetor adjustments, refer to Adjusting Car-
buretor, page 8.
3. By squeezing throttle lever, increase engine
RPM to speed required for operation before
placing trimmer under load.
IMPORTANT: Do not use trimmer at very low en-
gine speeds. Cutting efficiency will be poor and
clutch damage could result.
4. ALWAYS reduce engine speed to idle when
not trimming.
5. NEVER operate the engine at high RPM
without line extended.

3. A Get comfortable. Make sure support
handle adjusting knob is tightened securely
before operating Trimmer. When trimming
you should be standing in a natural position
without having to bend over or stand on your
toes.
4. Slowly move Trimmer in a side to side
motion into the area being cut, while, at the
same time, holding the unit at the desired
height of cut. Always tip the leading edge of
the cutter slightly downward to gain maximum
efficiency.
Figure 8
5. The life of your cutting line is dependent
upon following the above trimming tech-
niques, as well as whatis being cut, and where
the cutting is being done. EXAMPLE: Line will
wearfaster when run against a foundation wall
OPERATION
as compared to trimming around a tree. Some
line breakage will occur from moving unit too
fast, from entanglement with foreign matter,
from normal line fatigue, and from attempting
to cut thick, stalky weeds in excess of unit's
capability.
LENGTHENING CUTTING LINE (Fig. 9)
Your Toro Trimmer is equipped with an auto-
matic line feeding device so the line can be
lengthened without STOPPING THE ENGINE.
Note: Engine speed and noise will increase
noticeably when line wears down.
1. To lengthen line, firmly tap spool on the
ground while the engine continues to run at
normal cutting RPM (Fig. 9). The line will be
fed from the spool and cut off to the proper
length by the cutting knife attached to the
shield.
Remember to keep the engine speed up while
lengthening the line. Just tap the Trimmer on
the ground; do not hold it on the ground.
Note: The spool cap may wear during normal
use of the line advance feature and may
require occasional replacement.
Empty spools and spools prewound with 38
feet of cutting line are available through your
local Toro Dealer.
A Never continue to use a spool cap which
has been worn through, cracked or has chips
2 = out of it.
